Why Ionic Hybrid network becoming more popular day by day

Introduction of Ionic Framework

Ionic is a complete open-source SDK for hybrid mobile app development created by Max Lynch, Ben Sperry and Adam Bradley of Drifty Co. in 2013. Ionic is world’s most popular cross platform mobile development technology. Basically it’s hybrid mobile app development framework. Using Apache Cordova, it can be easily run on mobiles. A big advantage of using Ionic is that the code base remains the same for all mobile platforms and the UI/UX looks like a native mobile platform. The good news is: if you can manage to create websites, you already know how to build mobile apps. Ionic Framework offers the best web and native app components for building highly interactive native and progressive web apps. It is the only mobile app stack which allows developers to design apps for all app stores and the mobile web, using an unique code base. Moreover, Ionic’s Platform Continuity guarantees your app will look superb on every single device. Ionic provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by leveraging Cordova.

Benefits of Ionic Framework

Platform Independent Framework- Ionic can recognize the platform specific advanced CSS proportional to the native look and feel on different mobile operating systems. It reduces the requirement for code changing as it gives the codes of mobile-optimized HTML, JS, and CSS components. Apart from this, ionic integrates into Angular JS which becomes a robust structure making code excellent as well as more manageable. This empowers the Start-up entrepreneurs to come out with newer concepts at reduced budget.

Cross-Platform Mobile App Development with Ionic- Building an application without a moment's delay is essential, and it should be compatible with all mobile devices. However, it needs extremely limited use of time, assets and efforts, and helps in giving a unified look and feel. Besides, Ionic helps with building applications quickly and with expertise, and deploys standard tools with a solitary code base.

Default User Interface- Ionic has many default CSS and JS parts that cover the vast majority of the basic things you need to make a mobile application. . Apart from regular ones like buttons and navigation it also includes form inputs, lists, cards, sliding boxes and many more. These can be easily customized by adding CSS classes to the element. The default styles are basic, smooth, and you can without a doubt redo them by adding pre-defined CSS classes to the component.

Based on AngularJS- If you’ve worked upon Ionic, and then you would likely realize that it is developed on top of the Angular JS framework. The extensions to HTML's sentence structure offered by AngularJS are extremely useful for mobile app designers. The Ionic structure utilizes AngularJS to offer a bunch of center functionalities to the designer with the goal that they can incorporate alluring components into the application.  AngularJS is an ideal approach to make program based applications, while with the assistance of the Ionic structure, versatile designers can make hybrid applications and web applications.

Utilizes Cordova Plugins- Plugins play an essential part in Ionic application development. Modules are coded in JavaScript and come appended to the application. Ionic framework application development utilizes Cordova plugins to help designers in accessing different components of the versatile framework- for example, camera, GPS, and so on. According to your business and offered administrations, mobile app developers can utilize any of these modules to build their ideal mobile application.

There are a few good reasons to go with Ionic, depending on what you would be using it for:

1. Ionic use Angular’s MV* paradigm: If you are a web developer and want to be able to compete in the mobile space Ionic is great for you. Ionic uses HTML and CSS to lay out its views, so not only will you have all of the power of CSS transitions and canvas drawing, but you will also feel at home with the DOM. If you’ve ever used Angular in production, this will be doubly true for you, because the logic layers of Ionic use Angular’s MV* paradigm.

2.Desktop support: Ionic has added a flexible grid, and split-pane type features, allowing you to build mobile-first apps with responsive desktop layouts.

3.Open Web Standards: To paraphrase one of their founders, you’re betting on the open web, rather than getting stuck learning single-platform technologies that don’t carry over. (e.g. Learning CSS and DOM layouts versus Xcode’s autolayout)

4.Progressive Web Apps: This is a big trend on Google and Ionic’s radar, and it seems like Ionic is uniquely positioned to let you build app-class web experiences that can also be published in the App Store.

5.If you are bootstrapping a start-up and want to cut development time and cost by leveraging existing skill sets, Ionic is one of the best choices. Ionic creates apps for iOS, Android and Windows. It has default CSS that changes between versions for a Native experience. And all this can be done in JavaScript which is one of the most common programming languages known by developers now because of its ubiquity on the web. There are other frameworks around now that can achieve this in different languages, but most of them are not as popular or have as much support. So unless you have a specific reason you need to use python, Ruby, C++, Java etc. stick with Ionic or React Native in JavaScript or Xamarin in C#. Those are the most mature communities for cross-platform apps.

6. If you are new to web/mobile development the skills you will learn making things with Ionic will take you a lot further than what you will get with native. JavaScript is everywhere. It is more popular than Swift, and more importantly, it can be used for a lot more things. Java is really popular as well, but in my opinion, JavaScript seems to be slowly taking over Java’s position in the web development world. Companies that were built on java will stick around for a long time, but many new ones are being built on stuff like JavaScript, Ruby, Go and the like. And yes that list will be different in a few years, but Java will not be making it back on, and JavaScript will be the longest lasting one that is around for now.

7.Ionic Community: There’s a community of over 30,000 members on the Ionic forum, an active Slack Channel, and Ionic is the 45th or so most popular/starred repo on Github.

How to Install Ionic Framework

Make sure you have an up-to-date version of Node.js installed on your machine. If you don't have Node.js installed.

Open the command prompt and verify the Node.js version by using the command node -v.

To install Cordova and Ionic, use - npm install -g cordova ionic.

Make sure to install the latest version of JDK and Android Studio IDE for Android development.

To create a new project, use - ionic start projectname template.

Inside the project folder, you can add Android/iOS platform based on your development using the command - ionic cordova platform add android.

After these code changes are done, you can generate the required .apk file with the command - ionic cordova build android.

Once the .apk file is generated successfully, you deploy the file on a real device and do the testing, or you can test it as a web application using a browser.

To run it in a browser, use - ionic serve.

To run it on a device, use - ionic Cordova run android -device.

Finally, play with Ionic!

Angular Vs ReactJS – The Right Pick For Your Next Project

JavaScript frameworks are a dime a dozen in the development marketplace. Such frameworks are platforms that provide structures of application design for developing web applications based on JavaScript.

Angular vs Reactjs are two of the most famous front-end frameworks for web development. But how can you pick between the two?

If you're trying to decide whether to use Angular or React for your next project, it's important to understand the key differences between the two.

React is a JavaScript library, while Angular is a framework. This means that with React, you're getting a set of tools that you can use as you see fit, whereas, with Angular, you're getting a more opinionated structure.

React is also component-based, while Angular is template-based. This means that in React, you can break your UI down into small, reusable pieces, and then compose them together to create a complete UI. With Angular, you're working with templates compiled into components at build time.

When it comes to front-end web development, two of the most popular frameworks are Angular and React. Both these javascript Frameworks offer a lot of features and benefits that make them ideal for modern web development.

Finally, React uses JavaScript, while Angular uses TypeScript. This means that React is more flexible when it comes to the language you can use, as you're not limited to TypeScript.

However, there are some key differences between the two frameworks that you need to take into account before deciding which one to use for your next project.

Here’s a quick comparison of Angular vs React to help you make the right decision:

Angular:

- Developed by Google

- Uses TypeScript language

- Follows MVC structure

- Has a large community and extensive documentation

- Offers two-way data binding

- Ideal for large-scale projects

React:

- Developed by Facebook

- Uses JavaScript language

- Follows component-based architecture

- Has a small community but growing rapidly

- Offers one-way data binding

- Ideal for small to medium-sized projects

Also, Read this - Top Benefits of MEAN Stack for Web App Development

As you can see, both Angular and React have their own advantages and disadvantages. It’s important to evaluate your project requirements before deciding which framework to use.

So, which one should you choose? It really depends on your project and your preferences. If you're looking for a more flexible framework that will allow you to use the language of your choice, then React Developer is the way to go.

However, if you're looking for a more opinionated framework that will give you a fast and reliable structure, then Angular Developers is the right pick.

Vue vs React are frontend JavaScript frameworks famous in the developer world. Both tools offer developers a productive approach to developing diverse web programs, but everyone has their own satisfactory use instances and responds to specific enterprise desires.

React.JS JavaScript libraries, one may want to argue that the principal purpose for React JS’ fulfillment is that became birthed through none apart from Facebook itself however, this will be extremely simplistic. In reality, in spite of the truth that returned in 2013, the framework became launched to cater to Facebook’s desires, these days, this company backing is in particular indicative of each balance and reliability, and its miles utilized by many different organizations including Netflix, Yahoo, and Outlook.

📷

Vue.Js Vue is an open-source JavaScript framework evolved in 2014 through creative technologist evan you. At the time, you became accountable for UI/UX prototypes and innovative experiments at Google, and curiously sufficient, to be able to do this with each Angular and React. His suspicion has proved to be in large part, as Vue has additionally been followed through some of the big-call gamers like Nintendo, GitLab, and Adobe.

📷

Differences between vue vs react

Learning curveLet’s kick off our Vue vs React contrast with gaining knowledge of curves. While each framework is like one another, Vue is less complicated to work with. Both include legit documentation with masses of step references and realistic examples, but even as React is built across the internet additives method, Vue is capable of doing the equal in a substantially greater light-weight fashion. Vue vs React can also work additionally in tandem with effective JavaScript libraries for dealing with utility state Vuex and Redux respectively. And feature architectures to help complicated front-end which consist of module loading on demand.

📷

CommunityEven though its miles genuine are substantially greater tasks using React than Vue, it’s also not possible to disclaim the truth that Vue.js is speedy gaining ground. On GitHub, for instance, Vue has already handed React in the number of presented stars. This is essential because growing with Vue is frequently effective than react, as developers are capable of greater within an equal quantity of time.

CostSimilarly, as stated through the State of JavaScript survey, in practice, which means that in case you need to prepare your own software program development team, even though it can be less difficult to discover them, React JS builders will also be dearer to hire.

PerformanceReact is truly snappier at runtime, at the same time as Vue comes out on top in each reminiscence allocation and start-up times. In addition, whilst evaluating DOM manipulations, even though react can be quicker than Angular, its miles nevertheless slower than Vue.

Mobile development If you develop your app as soon as and reuse your code throughout a mess of devices, then React JS will absolutely be a great choice. The framework consists of React Native, which permits developers to develop local programs with JavaScript in the place of Android and iOS local technologies. In Vue’s case, through contrast, there are some specific alternatives for developing local mobile programs. Native Script is by some distance the maximum famous, even though each Wee and Quasar also are nicely really well worth checking out.

Vue vs React: When to use At SPG, we trust that each Vue vs React is similarly great gear for developing jaw-losing person interfaces. The bulk of our tasks are a mixture of Vue + Python or Node or React + Node or Java. But within this, identifying which one to apply in your subsequent task will depend upon many factors, along with the budget, use instances, your precise enterprise desires, and environment.

Conclusion Each framework has positive benefits over the opposite. For example, Vue is smaller and quicker, it’s handy because of its templates and has a simplified shape of syntax. On the other, react gives greater flexibility for larger, greater complicated apps. Also, it’s less difficult to check, greater suitable for mobile app development, and also you additionally have to get entry to greater data if you have trouble.

Blockchain is not a Cryptocurrency

In 2008, Bitcoin, the first and most successful cryptocurrency, used blockchain technology to create a network in which anonymous people could make non-fiat currency transfers without the need for intermediaries. After the birth of Bitcoin, many other cryptocurrencies began to be launched using blockchain, being today more than 2,000. However, blockchain is not a cryptocurrency, but it is a technology used by crypto currencies.

Beyond crypto currencies, the success of blockchain technology to generate consensus, function in a decentralized manner and resist hacking attempts thanks to the immutability of the information guaranteed by network cryptography, motivated the entrepreneurial community to consider it as an option attractive to build digital solutions at government and business level.

Once it is understood that blockchain is not a cryptocurrency but a decentralized record of information that is stored in the form of transactions that are grouped in blocks, questions such as what are the transactions. Or what are the participants and how do they interact with the network?

So What are the Key Elements of Blockchain to Design a Solution?

First, it is worth recognizing that not all blockchains are equal, as we anticipated at the beginning. Its main differences are the administration model, the level of decentralization or the degree of transparency, among other characteristics. The most used option when developing digital solutions with social impact value are the permissible networks, which allow companies and government institutions to use blockchain technology to decentralize information, generate consensus and increase the accuracy of validation and increase security. . The example we will give in this blog corresponds to a blockchain of this type.

However, there are certain ingredients that almost all blockchains have in common by default. The three key elements in the blockchain function are its participants, assets, and transactions.

1. Participants

The participants are all those groups that will play a role in the digital solution with blockchain. These include from companies that manage the network (if any) to ordinary users, through auditing entities, financial institutions, etc.

To size the role of each participant, it is worth asking: What are the permissions you will have on the network? How will you interact with the system? Will you have access to a copy of the entire chain? Can you see only the transactions in which you participate or will you have access to more information? What are the transactions you can perform?

Depending on what the answers to these questions are, participants will receive a copy of the entire chain or not and will have or not permission to view and / or validate transactions. Only participants who have a copy of the chain, even if they do not have access to all transactions because they are some private, are considered nodes. The rest, which will be accessed in general through a web service or a mobile application, are simply users.

2. Assets

Once we are clear who the participants are going to be, we need to know what they are going to exchange through the blockchain network. The way to understand this group is to think that when participants make a transaction, they are often transferring something. That “something” is the asset, and it can be a document, a certificate, a report, a token, a digital currency, etc.

It is also important to highlight that heavy documents are not stored in the blockchain but in databases connected to the blockchain, which also allows registering their modifications. This is motivated by efficiency issues, since all nodes have an updated copy of the chain and the inefficiency is directly proportional to the weight of the chain.

3. Transactions

The third element is transactions. Although we already know who is going to “play” (the participants) and what the “toys” (the assets) are going to be, it remains to be defined what the rules of the game will be. Transactions are how any modification is registered in the blockchain, from the change of a user’s permissions in the system, to the issuance of a certificate or the sending of an economic transfer. They can also be seen as the operations through which participants create, exchange, modify or destroy assets.

How to Bundle a Simple Static Site Using Webpack

Webpack has established itself as an indispensable part of the JavaScript toolchain. It has over 55,000 stars on GitHub and is used by many of the big players in the JavaScript world, such as React and Angular.

However, you don’t need to be using a front-end framework, or be working on a large-scale project to take advantage of it. Webpack is primarily a bundler, and as such you can also use it to bundle just about any resource or asset you care to think of.

In this article, I’m going to show you how to install and configure webpack, then use it to create minified bundles for a simple static site with a handful of assets.

But Why Would You Want to Do That?

Good question. Glad you asked!

One of the reasons for doing this is to minimize the number of HTTP requests you make to the server. As the average web page grows, you’ll likely include jQuery (yes, it’s still popular in 2020), a couple of fonts, a few plugins, as well as various style sheets and some JavaScript of your own. If you’re making a network request for each of these assets, things soon add up and your page can become sluggish. Bundling your code can go some way to mitigating this problem.

Webpack also makes it easy to minify your code, further reducing its size, and it lets you write your assets in whatever flavor you desire. For example, in this article I’ll demonstrate how to have webpack transpile modern JavaScript to ES5. This means you can write JavaScript using the latest, most up-to-date syntax (although this might not be fully supported yet), then serve the browsers ES5 that will run almost everywhere.

And finally, it’s a fun learning exercise. Whether or not you employ any of these techniques in your own projects is down to you, but by following along you’ll get a firm understanding of what webpack does, how it does it and whether it’s a good fit for you.

Getting up and Running

The first thing you’ll need is to have Node and npm installed on your computer. If you haven’t got Node yet, you can either download it from the Node website, or you can download and install it with the aid of a version manager. Personally, I much prefer this second method, as it allows you to switch between multiple versions of Node and it negates a bunch of permissions errors, which might otherwise see you installing Node packages with admin rights.

We’ll also need a skeleton project to work with. Here’s one I made earlier. To get it running on your machine, you should clone the project from GitHub and install the dependencies:

git clone https://github.com/sitepoint-editors/webpack-static-site-example cd webpack-static-site-example npm install

This will install jQuery, plus Slick Slider and Lightbox2 — two plugins we’ll be using on the site — to a node_modules folder in the root of the project.

After that, you can open index.html in your browser and navigate the site. You should see something like this:

If you need help with any of the steps above, why not head over to our forums and post a question.

Introducing Webpack to the Project

The next thing we’ll need to do is to install webpack. We can do this with the following command:

npm install webpack webpack-cli --save-dev

This will install webpack and the webpack CLI and add them to the devDependency section of your package.json file:

"devDependencies": { "webpack": "^5.1.3", "webpack-cli": "^4.0.0" }

Next, we’ll make a dist folder which will contain our bundled JavaScript:

mkdir dist

Now we can try and run webpack from the command line to see if it is set up correctly:

./node_modules/webpack/bin/webpack.js ./src/js/main.js --output-filename=bundle.js --mode=development

What we’re doing here is telling webpack to bundle the contents of src/js/main.js into dist/bundle.js. If everything is installed correctly, you should see something like this output to the command line:

asset bundle.js 1.04 KiB [emitted] (name: main) ./src/js/main.js 192 bytes [built] [code generated] webpack 5.1.3 compiled successfully in 45 ms

And webpack will create a bundle.js file in the dist folder. If you have a look at that file in your text editor of choice, you’ll see a bunch of boilerplate and the contents of main.js at the bottom.

Automating Our Setup

If we had to type all of the above into the terminal every time we wanted to run webpack, that’d be quite annoying. So let’s create an npm script we can run instead.

In package.json, alter the scripts property to look like this:

"scripts": { "test": "echo \"Error: no test specified\" && exit 1", "build": "webpack ./src/js/main.js --output-filename=bundle.js --mode=development" },

Notice how we can leave out the full path to the webpack module, as when run from a script, npm will automatically look for the module in the node_modules folder. Now when you run npm run build, the same thing should happen as before. Cool, eh?

Create a Webpack Configuration File

Notice how we’re passing the path of the file to bundle and the path of the output file as arguments to webpack? Well, we should probably change that and specify these in a configuration file instead. This will make our life easier when we come to use loaders later on.

Create a webpack.config.js file in the project root:

touch webpack.config.js

And add the following code:

module.exports = { entry: './src/js/main.js', mode: 'development', output: { path: `${__dirname}/dist`, filename: 'bundle.js', }, };

And change the npm script to the following:

"scripts": { ... "build": "webpack" },

In webpack.config.js we’re exporting a configuration object, which specifies the entry point, the mode webpack should run in (more on that later), and the output location of the bundle. Run everything again and it should all still work as before.

Including the Bundle

Now that we have webpack generating a bundle for us, the next thing we need to do is to include it somewhere. But first, let’s create a different entry point, so that we can list the assets we want webpack to bundle for us. This will be a file named app.js in the src/js directory:

touch src/js/app.js

Add the following to app.js:

require('./main.js');

And change the webpack config thus:

entry: './src/js/app.js',

Run npm run build again to recreate the bundle. Everything should work as before.

Now, if you have a look at index.html you’ll notice that there’s not much going on JavaScript-wise. At the bottom of the file we are including jQuery and a file called main.js, which is responsible for showing more information when you click the Read more… link.

Let’s edit index.html to include the bundle instead of main.js. Look at the bottom of the file. You should see:

<script src="./node_modules/jquery/dist/jquery.min.js"></script> <script src="./src/js/main.js"></script> </body> </html>

Change this to:

<script src="./node_modules/jquery/dist/jquery.min.js"></script> <script src="./dist/bundle.js"></script> </body> </html>

Refresh the page in the browser and satisfy yourself that the Read more… link still works.

Bundling jQuery

Next, let’s add jQuery to the bundle. That will reduce the number of HTTP requests the page is making. To do this, we have to alter the app.js file like so:

window.$ = require('jquery'); require('./main.js');

Here we’re requiring jQuery, but as we installed this using npm, we don’t have to include the full path. We’re also adding its usual $ alias to the global window object, so that it’s accessible by other scripts. We’re requiring main.js after jQuery, as the former depends on the latter, and order is important.

Alter index.html to remove the jQuery script tag:

<script src="./dist/bundle.js"></script> </body> </html>

Run npm run build and once again, refresh the page in the browser to satisfy yourself that the Read more… link still works. It does? Good!

VueJS & Firebase Cloud Firestore Stripped-Back - Tutorial Part 1

In this tutorial series we will explain how to start developing with the Vuejs framework & Firebase Cloud Firestore to build full-stack web applications. We’ll start from scratch by stripping everything back to the basics - no CLIs, build tools or bundlers, just a HTML page, an editor and a browser so you can get to grips with building apps with Vue & Firebase more quickly and be productive faster.

VueJS

Vuejs is now one of the big 3 Javascript frameworks in the web client ecosystem. However it’s not developed or backed by a huge corporation, it was developed by one individual, Evan You. The proliferation of JS frameworks in recent years has led to the term “Javascript Fatigue” where developers have become weary of all of the new and self-proclaimed “latest and greatest” open source frameworks. It is in this environment that Vue has emerged through all of the noise to become a major player alongside Angular and React (both backed by huge technology companies, Google and Facebook respectively). That Vue has achieved such a status in this environment backed by one individual highlights just how Vue has hit a chord with developers and is filling a gap that isn’t being met by Angular, React or other competitors like Ember and Aurelia.

Evan You is an ex-Googler who was familiar with AngularJS (often referred to as Angular 1) and used it for internal projects at Google that he was working on. He set out to achieve a framework that delivered the benefits of AngularJS but was more lightweight, faster and better suited to smaller apps that didn’t require the heavy-lifting of the huge apps that AngularJS was originally built to develop such as their Adwords platform and their internal CRM system. What he produced was a beautifully simple solution and it quickly attracted adoption as the front-end framework of choice for many PHP developers, particularly from the Laravel community.

Despite promising early adoption in some quarters, Vue may well have stayed a “me-too” framework in the ecosystem had it not been for Google’s decision to redevelop their AngularJS framework from scratch. Angular (often referred to as Angular 2) was such a departure from the original AngularJS framework that it introduced a fundamental shift in approach and required developers to learn many new concepts just to build basic apps. Developers were kept in limbo between AngularJS and Angular for almost 2 years, with many alphas and then  betas and many breaking changes and missing pieces to deal with during the transition and then no easy migration path for their existing code and apps.

There’s no doubt that, as a new framework in it’s own right, Angular is a fantastic, powerful, all-in-one next generation framework but it isn’t “Angular” as millions of developers know it. Perhaps the biggest mistake Google made was in not launching their next-gen framework under new branding. In any event and unfortunately for Google, Angular 2 was too big a change for many developers and while uptake was initially high, it hasn’t achieved the type of ongoing adoption or love as AngularJS or React and it’s clear that Vue, with many obvious similarities to the original Angular, has arrived just in time to sweep up and become a magnet for disgruntled Angular devs.

In addition, the droves of developers jumping in to the Javascript ecosystem over the past years, in their evaluation of an appropriate framework, are choosing Vue in vast numbers due to how easy it is to learn and how quickly they can start building apps. I would say that the best word to describe Vue to developers choosing a framework is “approachable” - it seductively invites you in and once there you find it’s so intuitive and simple to get productive, covering all of the bases you need, that once you’re in you tend to stick with it. For me personally I actually enjoy spending my days developing around Vue, I cannot say the same for Angular unfortunately.

In 2018, Vue is set to gain even greater momentum and overtake Angular into second place in the Javascript framework popularity chart. The main reason for this may be that the massively popular Ionic mobile and PWA framework is about to release a version that decouples it from Angular and enables developers to build apps with Ionic using any framework (or none at all). It’s interesting that this is likely to be a tipping point for Vue to achieve critical mass and yet is due to the Ionic team’s concern that Angular isn’t seeing the level of adoption anticipated and continuing to hitch their wagon to Angular is likely to hamper their own growth.

To address this, in Ionic 4, they’ve developed a framework-agnostic, web component-based edition of their mobile framework. When you look online it’s fairly clear that the majority of the delight at Ionic’s shift away from Angular is coming from those who want to use Ionic with Vue. Personally I only stuck with Angular because of Ionic despite my preference for Vue and since their announcement of Ionic 4, I have thrown myself fully into Vue. The sweet spot that Vue hits between Angular and React is in delivering a more lightweight and simple approach than Angular, focussing first and foremost on being a view renderer like React but providing optional elements that are officially supported and developed by the Vue core team, such as routing that can be easily dropped in to your app. This is what is meant when Vue is called a “progressive framework”, you can start by using as little or as much of the framework as you need, progressively using more of it’s subsidiary elements as required. Another advantage to using Vue is that it’s lightweight enough to use it in one part of your app and progressively expand it to other parts when you’re ready, for example if you have existing app in vanilla Javascript, jQuery or another framework that you want to change over to Vue piece by piece.

As mentioned, Vue’s biggest advantage is it’s simplicity and approachability. While other frameworks require knowledge of build systems, CLIs, Node, NPM etc just to start building an “Hello World” app, with Vue you can strip everything right back, open up an HTML file in an editor and get started simply without needing to spend time learning anything else. While you’ll likely want to move over to the full modern JS development environment as you get more involved, it isn’t required to get started.

Firebase Cloud Firestore

So Vue is a fantastic front-end framework but to build even the most trivial worthwhile app, we need a back-end and a data store. Like with using Vue, we want to use something that delivers simplicity and approachability yet gives us the power to build advanced apps as you become more experienced. For this project Firebase Cloud Firestore is a no-brainer to use as the database back-end. Like Vue, we can just get started using Firebase with just a basic HTML page - no need for CLIs and build tools to just start building something.

I first used Firebase back in 2014, when they were a small, private company shortly before they were acquired by Google. At the time Firebase was not a platform but a hosted realtime database and I fell in love with it immediately - for prototyping it was perfect and it’s realtime capabilities were just awe-inspiring at the time.

However Firebase did have some serious limitations that made it unsuitable for me to use as the back-end database in a production app. It didn’t allow server-side code, so all of your logic was exposed on the client and it’s database querying facilities were extremely limited. Also, as a No-SQL document database, organising relational-style data into something that was manageable without joins and queries required denormalisation and duplication of data, something which is anathema to those coming from a SQL-based relational database background. I felt it was a real shame as, despite these limitations, it was very impressive and working with it’s Javascript API was a joy.

After Google’s acquisition, Firebase was expanded into a full serverless platform allowing for storage, cloud messaging, hosting, authentication, analytics and much much more. What had been “Firebase” became the Realtime Database element of the platform. Fortunately Google started to address the limitations that I and many other developers had found with the original Firebase. First server-side code, in the form of Cloud Functions, was added which enables you to put more of your sensitive business logic code onto the server.

More recently Google introduced an alternative database to the original realtime database which they call Cloud Firestore. Cloud Firestore addresses many, but not all, of the issues with the realtime database in terms of querying and organisation of data. It still provides the full realtime capabilities that we know and love and is still a No-SQL database based on documents. However you can now organise them into Collections (similar to relational DB Tables) which enables you to perform much more advanced queries. You can have specifically defined fields each of which can have a specific type. One of these types is the Reference type which lets you store links between documents on different collections to enable a form of join. In addition Cloud Firebase enables offline usage so the user can continue to use your app even if access to the server isn’t available. There are still limitations, remembering it’s not a relational database, and full joins are not possible and neither are aggregate queries such as SUM, COUNT etc. However with 90% of the issues I had with the original Firebase realtime database now dealt with through Cloud Functions and Cloud Firestore, Firebase is now an excellent choice as the back-end, serverless platform and data store for building full-scale production apps.

OK so enough talk about the what and why, let’s get going with the how and write some code. We’re going to start, as we’ve talked about, with a single HTML page. Choose your OS, code editor and browser of choice (I’m using VSCode on OSX and highly recommend using Chrome as your browser).

Open up your editor and select to create a new file in a new folder. Just call the new file index.html. Once you’ve done this, start with a skeleton html page as shown below :

<html>

     <head>          <title>VueJS & Firebase From Scratch</title>      </head>

     <body>

     </body>

     <script>

     </script>

<html>

The first thing we’ll need to do is to import the VueJS library. We can do this with a CDN link (see below) which is placed below the closing body tag and before the opening script tag  :

<script src="https://cdn.jsdelivr.net/npm/vue"></script>

This recommended CDN link is correct at the time of writing however may change in future. To ensure it’s correct, once you’ve inserted this link into your page, save it and open it up in Google’s Chrome browser (select File from Chrome’s menu and select Open File … to navigate and select your newly created index.html file). The page will show as blank in any case however right-click on the page and select Inspect from the pop-up menu and click the Console tab. If this displays nothing eg there are no error messages then you’re good however if you do get an error complaining about the vue library then browse to https://vuejs.org/v2/guide/ and look for the link displayed under Getting Started.

We’re ready to build our app! The first thing we need to do is to create the Vue Instance Object that will be used as the core of your app.

<script>      var app = new Vue({                           el : '#app'      }) </script>

This creates a new Vue instance that we can reference throughout our html template and which contains all of the data and methods that we’ll create to develop the app. Some call it the View Model however we’ll stick to calling it the Instance Object. We simply create a new object called app from Vue and pass in an object with all of the information about our app. To begin with, we only declare a single property in this object which is el, short for element, and we assign #app. This tells Vue that any reference to an element that has the id of app is to be controlled by our Vue Instance Object.

In our html template we can now simply create a container html tag and assign it the id of app. All of the content within that tag is then controlled automatically by our Vue instance object. (Please note that any content in bold from here on in denotes new or changed content.)

<body>

     <div id=‘app’>

     </div>

</body>

Please note : Unlike AngularJS, with Vue you cannot assign the reference to the Instance Object on the body tag, you have to create your own container tag to assign it to, as in this case we’re assigning it to a div container.

Great but we’re not actually doing anything yet. Now we want to give our app some life. To do this we’ll give the app a name and display it as a title and we’ll do this as data held on the Instance object rather than write it directly on the template. To do this we’ll need to add another property called data to our instance object. The data property is an object which contains any variables you want to reference in your template or elsewhere in your app. In this case we’ll create a variable called appTitle and assign it a name. The app we’re going to build is an employee tracker that is going to be so indispensable to it’s users that it will be like magic!

<script>      var app = new Vue({                           el : '#app’,                           data : {                                       appTitle : ‘EmployeeMagic’                           }      }) </script>

We can now use the data binding features of Vue to display our new app title in our page template.

<body>

     <div id=“app”>

         <h1>{{ appTitle }}</h1>

     </div>

</body>

Save and refresh your page in Chrome and you’ll see EmployeeMagic as your app header. The double curly braces are pretty standard in most frameworks these days to denote data-binding (also called interpolation). The content inside the double-curlies is interpreted by Vue and the required content is displayed at that point in the template. In this case Vue recognises that we have a variable called appTitle in data in our Instance Object and replaces it in our template with the value contained in the variable. There are many benefits of data-binding, the main one being that any change in the variable in our instance object is automatically reflected in our template without any additional effort on our part.

So far so good but it’s a little plain-Jane so let’s add the Bootstrap library link for a bit more aesthetic to it without any extra effort. The link used below for then Bootstrap CDN was current at the time of writing however check the Bootstrap website if you have trouble with the link :

<header>      <title>EmployeeMagic</title>

     <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.3/css/bootstrap.min.css"/>

</header>

Let’s say however we want to add a margin around the app so it’s not displaying right up against the edge all the time. To do this we’ll need to add some CSS styling however we can take advantage of a cool Vue feature which lets us set our styles programatically.

Let’s add another variable to our data object which is specifically for styles, let’s call it mainStyle. This will be an object so that we can assign as many different CSS style settings as we like. For now we just want to assign a margin of 20 pixels :

<script>      var app = new Vue({                           el : ‘#app’,                           data : {                                      appTitle : ‘EmployeeMagic’,                                      mainStyle : { ‘margin’ : ‘20px’ }                            }      }) </script>

Now we need to tell Vue where to use that styling property in our template. We’ll create a new container div tag to wrap around the rest of our app. In that tag we need to tell Vue to assign the styling we’ve defined in mainStyle. To do this we can use a Vue directive called v-bind:style and assign it the name of style object we want to use.

<body>

     <div id=“app”>

         <div v-bind:style=“mainStyle”>

             <h1>{{ appTitle }}</h1>

         </div>

     </div>

</body>

Save and refresh in Chrome and you’ll see the margin has been applied. I personally love this feature of Vue and there are lots more you can do to apply styling which we’ll cover later in the tutorial.

It’s interesting to note that when using directives such as v-bind:style, Vue offers a more shorthand way by dropping the v-bind. If Vue just sees :style it knows what to do, so we could have used ...

<div :style=“mainStyle”>

... instead. Throughout these tutorials I’ll continue to use the more verbose version to show the full directives consistently however where a new directive is shown, I’ll also highlight the shorthand version. Generally if you see v-bind followed by a colon and the command, you can drop the v-bind although there are exceptions that we’ll cover in a future part of the tutorial.

We’ve so far covered what VueJS and Firebase Cloud Firestore are, why we’re using them as the framework and platform for this app, and the basics of setting up a simple HTML page to build our employee tracker app, setting up our Vue object, basic data-binding and styling using a Vue directive.

In the next 4 parts of this tutorial we’ll focus on each element of CRUD (Create, Read or Retrieve, Update and Delete) so in part 2 we’ll deal with Creating records to store in our Firebase Cloud Firestore.

Hope you can join me in Part 2 :)

React

React is a product of Facebook. It is a very flexible and efficient Javascript library for building interactive user interfaces. React forms the view layer of the web application which is technically the frontend. This makes it easier to make web applications with essential features such as reusable components, state management, DOM rendering and many more which are explained later. React is mainly used in making single-page web applications. In this article we'll see the fundamentals of react library and why is it so popular.

Features

Components

ReactJS makes use of components which are independent and reusable bits of code. In other words, components are functions that work in isolation and each component manage their own state. It makes building web applications very much easier when individual blocks of elements are broken down while building large scale applications.

Virtual DOM

Every time there is any changes in the original DOM. The whole application is re-rendered onto the virtual DOM. The difference between the original and virtual DOM is checked and only this difference is updated in the original DOM. This boosts the speed of react application as the page need not be refereshed to see the changes.

Declarative

Designing any view on React is very easy and they manage their own state. React will make sure to render just the right components onto the DOM which enables the user to easily maintain and debug the code.

JSX

JSX stands for Javascript XML. It is a mixture of both Javascript and XML. As talked about earlier, the react is made up of components. These components have both javascript logic as well HTML/XML to render onto the screen. These component files have an extension .jsx.

Performance

React is ridiculously fast. Its virtual DOM minimizes the re-rendering of entire DOM unnecessarily. Also, React uses one-way binding (unidirectional data flow) using a pattern called Flux. This makes the components immutable hence, giving more felexibility and efficiency.

Why React?

Easy to learn

Compared to other libraries or frameworks out there like Angular or VueJS, React is comparably easier to learn and handle. With the basics of HTML, CSS and Javascript in place, you are ready to get started with React.

Simplicity

React is very simple to use. It has some very powerful packages to run its engine like webpack. With some simple JSX you will have components rendering independently on your screen. React becomes such a powerful tool when used with other JS libraries such as Redux, Material-UI, Materialize, GraphQL, etc.

Used by Developers

React is the most loved library compared to other libraries out there. React is open-source and has active contributors on its GitHub. The repository itself has over 150,000 stars and it's used by 3.8 million developers.

React Native

React can also be used to create mobile apps. And this version of react is called React Native. This shows the power of react's flexibility to adapt. With the perfect plan and execution a developer can make an app for android, iOS and the web.

Setup

React is incredibly easy to set up in the beginning and doesn't require frequent set ups if the package has been installed globally on your system.

Make sure to install NodeJS and NPM( Node Package Manager) on your system before installing react.

To install react, run the following command:

npx create-react-app <your-app-name>

After the installation is completed, go into your app directory:

cd <your-app-name>

Run to see your default app:

npm start

Result

You see a beautiful React App running on your browser. Feel free to play around with the files in the src folder of react to make your own web or mobile app.

How to become a Web Developer: a detailed plan for learning JavaScript

Everyone who wants to become an IT developer usually begins with making sites, as the easiest part of it. To work, you need only a text editor for writing the code and browser to see visually what you are doing. If you're not aiming to a full-stack approach and you just want learn the magic of client-side programming, you won't have to study complicated algorithms: as a matter of fact, the main skill each client-side web developer must have nowadays is the knowledge of JavaScript (and its frameworks). The best way to learn is by creating own website using multiple technologies. For example, you can create website and display stats from popular games like Counter-Strike and Valorant. Such a project requires HTML, CSS, Git, Bootstrap, JavaScript, Bash, MySQL. A nice example is the Valorant Tracker project, which is something that could be done in 4-6 months if you're willing to learning JavaScript programming. Once you manage to pull off something like that, you'll have a good chance to get hired as a junior code in a decent company and start your developer career. Nowadays, JS has been developing incredibly fast, so it's easy to get confused while studying this language. We offer you an educational plan with a convenient structure, where you will find all the main aspects of JavaScript and other adjacent technologies.

Why JavaScript?

We have to mention that language being pretty open - many companies are rivaling using JS with the goal of its evolution. The language is incredibly flexible, so it is perfect for people who like both object-oriented and functional approaches. A mammoth amount of different libraries and frameworks allows you to solve even the most difficult issues. Moreover, the server platform Node.js allows you to use JS not just in browsers but on the console. You can create apps for both smartphones and PC. Apps for a computer by using the Electron framework, and mobile apps thanks to NativeScript or ReactNative.

Git

The first thing you should do is to study how Git works: a source code manager is a vital instrument for developers, so you have to learn it first - since it's arguably the best choice nowadays. Here are three common topics you might start to learn to quickly understand the basics: Creation and moving of the files across catalogs. Initialization and commits in Git. Repositories settings in GitHub. Also, you must have the next skills: Object-oriented JS - constructors and factories. Functional JS - functions of the highest order, circuit, and recursion. Specification of the Jasmine tests. Basics of the HTML, CSS, and jQuery. To better understand these topics, be sure to check out our posts, guides and tutorials regarding Git and GitHub.

Algorithms and data structures

Later you have to learn algorithms (especially big complicated ones), and basic data structures: connected lists, turns, stacks, binary searching trees, and hash-tables.

Back-end JavaScript frameworks

Node.js - Approximately a decade ago JS was used only for writing the code for front-end (just like CSS and HTML), but today due to Node.js the situation is quite the opposite. Node - is a server area for committing all the actions by JS, so you won't have to learn all the new syntax. Although, you will have to import and export files, divide the entire code for modules, and use the pack-manager NPM. Express.js - Besides learning Node you have to get more knowledge about back-end development, especially about servers and routing. Ports and protocols with HTTP will be a nice start before studying Express. Express.js - Node-library for requests` processing.

Asynchronous JavaScript (AJAX)

If you don’t want to refresh your page after each change in your DB, Ajax is certainly what you will need - it sends asynchronous HTTP-request to reload only part of the page. You can work with Ajax through the jQuery (see below) or by directly (manually) handling the XMLHttpRequest object. Asynchrony is the thing that makes JS unique but separating developers into two sides: some love it and some hate. Each developer has to know both advantages and disadvantages of that technology. You can start by studying call stacks, events cycles, and callbacks, then - studying promises.

Databases, Schemes, Models, and ORM

Databases one of the most important parts of web development. If your app has to save or load some information without losing it just after the page's update, you definitely will have to use DB. You have to learn how to see the difference between relational and non-relational DB and learn their connection ways. The next step will be studying the SQL and different systems for controlling DB. Knowledge of ORM won't be excessive.

HTML and CSS

Those languages are the very basics of the web-design. You don't have to know them perfectly but understand their code. Then you will have to learn at least one popular library (for example, Bootstrap). For CSS you have to learn processors, like Sass that will make CSS more similar to the normal code. For making work with the HTML you can pick any template, like PUG. To better understand these topics, be sure to check out our posts, guides and tutorials regarding HTML, HTML5, CSS and CSS3.

jQuery and DOM manipulations

After you finished the main look of the page using HTML and CSS, you will use event translators and jQuery for the DOM controlling. Many people think that jQuery is useless and soon will be replaced by Angular or React. Maybe it's true, but jQuery is worldwide popular, so in any case, you must know it. Moreover, you can get into the situation when you will have to do an incredibly complicated job using React-microscope, so in that situation, light jQuery will be your salvation. To better understand these topics, be sure to check out our posts, guides and tutorials regarding JQuery.

Chrome instruments for developers

If we didn't mention the Chrome instrument which makes the programming job easier, we wouldn't forgive ourselves. Thanks to them you will be able to learn DOM, debugging process through the console, routes` tracking and so much more.

Test-Diven Development

Also called TDD: this is the development tactic when the software divides for a few tiny cycles: Writing down the code to make all changes you had to. Writing down the code that will pass all tests. Refactoring the code and writing new tests if those are necessary. If some parts of the code don't pass the test, they have to be rewritten. If you work with JS we firmly recommend you pay attention to the Jasmine, Chai, and Mocha frameworks. To better understand these topics, be sure to check out the ASP.NET Core 3 and Angular 9 book, which features an entire chapter about client-side TDD using the Karma test runner and Jasmine testing suite.

Web Sockets

We have to pay extra attention to that topic because web-sockets are useful. WebSocket protocol, unlike the HTTP one, will allow you to work with a bidirectional data stream – the reason why is that tech unique. The most popular library called socket.io and is well documented here.

EcmaScript 6 (ES2015)

Nowadays, the main standard is ES6 (ES2015), ES2016 has been confirmed already and the ES2017 is under development right now, so you always have to watch their updates and use the newest and most stable version. All compatibility problems can be solved easily with the next apps.

Babel

Babel - compiles ES6 (ES2016 support is expected soon) into the ES5, which is well-known by all browsers. It also can compile JSX/REACT-components, which makes it vital for web-developers. Webpack - takes all your files (images, fonts, style tables, JS-files, etc) into the single dependency graph. You don't have to use it if you are making a small app but shall use it while working with React.

React and Redux

React (also known as ReactJS) - the library which will allow you to create a user's interface. It was created by Facebook in 2013 and became worldwide popular pretty fast. React is needed not just for web-design, but there are versions for smartphones (React Native) and VR (React VR), published later by the same company. Redux - container of predictable states, usually used with React. It can be used for shortening the code by the modeling way. Pretty useful in real-time working apps with a big number of users, such as games. To better understand these topics, be sure to check out the series of React & ReactJS articles we've published in the last few years.

Authentication, Sessions, Cookies

You have to understand how the app will interact with users - how users will log in\out of their accounts, get bonuses, etc. For identifying people during surfing your site, web-sites using cookies - small text-files that send a reply from server to browser for user's HTTP request. For the connection between DB and log-in page, you can use the express-session library.

Web Security

Each site/app, of course, must be secure and reliable. You have to get the knowledge of all possible attacks on your creation and ways of protection as well. To better understand these topics, be sure to check out the various IT & Development Security articles we published in the last few years.

Conclusions

In this post we tried to write a list of the main study topics that await a novice JavaScript developer. Most of these tools will become your best friends, others will make you spit blood: each of them, however, will help you better understand how to overcome the inevitable difficulties that await your learning path and satisfy the development requests of the clients.

Top 20 React JS Application Examples

React js, created by Jordan Walke, Software Engineer at Facebook, is one of the most popular frameworks for developing user interfaces of a web application. React js is the famous front-end library used by most of the developers.

There is so-called architecture in the app development process, MVC, where M is Model, V is View, and C is Controller.  

Model is taking care of application data and business logic; the view is the UI of the application where the data is displayed; the Controller takes care of user requests from the view and renders it with the model.  

In simple, MVC is a software pattern to build UI where the views are separated from the model and controller so that one’s change cannot affect the other. Since V is the UI, in this, React JS is only based on V (i.e.,) View. React js is also used for creating reusable UI components.

Amazing Features of React js:

Every technology has its features to develop apps, so you have to know the features of react js.

Data Binding: With a required callback function, one-way data binding allows developers to modify the properties of React js. This helps to maintain good data flow in the application.

Virtual DOM: DOM- Direct Object Model. The virtual DOM helps React js to build an application that is faster, reliable, and scalable.

Components: React js components are developed with some logic that is used for visual interactions of the UI in an app.

React Native: React Native is a popular mobile app development framework that uses React js to build its components for different platforms like Android, iOS, Windows.

To know their exact differences, visit here: Difference between React js and React Native

Why React JS is Popular?

One of the most important questions for any business willing to develop an application is, “which front-end technology (client-side) should we choose?” With so many options for JavaScript frameworks available, your app development team needs to be cautious about their choice. This article will examine the positives and negatives of React, Angular, and Vue and situations in which each is optimal to use. What Is Angular? Angular is an open source, frontend web app framework by Google that has a Model-View-Controller (MVC) architecture and makes development, maintenance, and testing easier for developers. It’s great for building highly active and interactive web applications, but it is most popular for Single page applications. Latest Angular release cycle Source You may also like: Everything React: Tutorials for Beginners and Experts Alike. What Is React? Introduced by Facebook, React is an open source JavaScript library for building interactive, stateful, and reusable user interfaces (UI). It is good for rendering complex UI with high performances. It also works with the basic fundamental of virtual Document Object Model (DOM) to offer a highly stable web application. React Native What Is Vue? Vue is a progressive JavaScript framework for building user interfaces. Vue is designed from the ground up to be incrementally adoptable. It comes with various optional tools for building user interfaces. Vue has a high capability of backing sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries. Popularity Well, if you see the analytics snapshot of Google trends, Angular was very popular until 2016, but from 2017 on, searches for React are steadily growing. Popularity by Google search traffic The Stackoverflow also shows the popularity of tags. Between “AngularJS,” “ReactJS,” and “VueJS” and popularity of React is clear. Popularity by Stack Overflow searches With every new update, React, Angular, and Vue come with new features that further offer reliability and stability to the web apps. Difference Between Angular, React, and Vue Differences between Angular, React, and Vue Benefits of AngularJS Web applications built on Angular run in any browser environment, regardless of the platform. Two-way, or bidirectional data binding, ensure that data change in the model will reflect in the view immediately, and when data in the view changes, the model is also updated. Two-way data binding The pre-built material design components help in building a highly interactive and easily navigable UI for your mobile/web app. The Angular Command Line Interface ensures easy updates of components from third-party which reduces the time to create apps and deploy the same. Benefits of React Virtual DOM helps React developers an easily render any changes in the application without affecting the other parts of the interface. React allows users to reuse components. This makes app development easier and more efficient. React uses Redux, which simplifies storing and managing component states in large applications. Unidirectional data binding makes code stable and supports future development as the data flow is directed towards one direction. Benefits of Vue One of the most significant benefits of Vue is its small size.  It comes with detailed documentation. It allows developers to write a template in an HTML file, JavaScript file, and pure JavaScript file, using virtual Node. Its MVVM architecture makes it quite easy to handle HTML blocks. Finding the Right Framework for You Performance Performance is the most important aspect of a frontend application. HTML requires much attention from the developers. Both React and Angular take completely different approaches to update HTML that in turn affect the performance of an application. However, considering the direct changes in DOM in the browser, Angular is best suited for Single-page applications, where the content is updated occasionally. On the other hand, React can be selected for applications of any size, which needs content update regularly (for example Instagram). While talking about Vue.js performance, its core library is focused on the view layer only and is easy to pick up & integrate with other libraries or existing applications. Vue.js also comes with virtual DOM delivering high performance and memory allocation. However, these three frameworks are comparatively faster than other JavaScript frameworks. Speed of Development Though modification is easy with both React and Angular, the speed of your application depends on the number of libraries with the functionalities that are available to the developers. React’s architecture is easier to scale than Angular, but developing a web app in Angular is faster than React. For rendering a relatively complex UI with some user interaction, all three frameworks are a great choice. But, if you are looking for something that you can add to your app instantly, Vue is an excellent choice. Vue makes it easy to go from prototype to product. Application Size Angular holds all the necessary parts of a Minimum Viable Product to produce a fully functional Single-page application. If you want to regulate the size of your app and keep it small and compact, then Angular is the best choice. On the other hand, React is a great choice for applications that you desire to expand in the future across multiple operating systems. Vue's core library is created to be focused and flexible. As a result, Vue is great for applications of any size: single-file components, highly modular component interface, platform options with Vue CLI3, etc. So, if you are using it for a moderately complex single page or larger-scale app that includes navigation between multiple pages, it will work well. Some popular examples of these JS frameworks Conclusion While React gives you flexibility and simplicity, Angular is a comprehensive framework. But that doesn’t help a lot when developers don’t need most of the features that Angular provides. Due to Reactjs’s implementation with a virtual DOM, it guarantees better performances than Angular. Being a progressive framework, Vue can be combined into an existing project. It comes with a vast set of tools and companion libraries that allow the framework to respond to the complex needs of enterprise-grade applications. Also, with Vue CLI 3 and Vue UI, it is great for quickly delivering MVPs. Vue is also a cost-effective solution for small and medium applications. Further Reading

What’s new in Angular 8.0?

Angular 8 is the first major release from Google in the year 2019. It has focused on the toolchain and also making Angular easier for users for different applications development with performance improvements. But this, major version release also contains some new features and upgradation with respect to the previous versions. New Angular version is much lighter, faster and easier. Angular 8 supports the TypeScript version 3.4. So, using the new TypeScript version, it is easy to code with faster subsequent build with the incremental flag, type checking for globalThis, and generic type arguments. With the new release now available, it’s important to understand what has changed so you’ll know how to approach Angular 8.

New features of Angular 8-

1. Angular Ivy-

If you’re not familiar with Ivy, is it something you should think about? If the case is that, user experience of your apps is significant for you, then Ivy is definitely something you should think about. In spite of the fact that the system has made huge upgrades in file size and runtime speed since the times of Angular 2, Angular applications frequently will in general be on the substantial side with regards to file size and memory use.

Compared with the current Angular View Engine, Ivy provides the following benefits:

The code generated by the Angular compiler is now much simple to read and understand.

Rebuild times are significantly faster

Decreased payload size, so it will take browsers less time to download and parse your applications.

Better template type checking, so you can catch more errors at build time and prevent your users from encountering them at runtime

Over this, Angular Ivy aims to be broadly compatible with existing Angular applications, so preferably, you’ll have the option to get the majority of Ivy’s advantages without changing your applications at all. There will be some bugs and hiccups, however. So it’ll be helpful to develop your current Angular apps using Angular 8 and Ivy. There are some areas where Ivy is lacking—in particular, internationalization and Angular Universal support aren’t yet fully compatible. So if your Angular app supports multiple languages and additionally uses server-side rendering, don’t expect it to be ready to work with Ivy just yet.

2. Web Worker support-

As we all know that JavaScript executes in a single-threaded manner. So, to perform any huge data call or any consecutive Rest API call in an asynchronous manner is essential. But, in real application based scenario, this concept will not help us. This is because today all the web browser support the web worker process. Basically, the web worker process is the scripts executed by the browser in a separate thread. Communication with that thread in the browser tab will be carried out by sending messages. So, in general, web worker is not related to Angular from any point-of-view. But, the main point is that these scripts should be considered in the build process of the application. So, that after deployment of application the same process can be performed continuously. Hence, the main objective is to provide one single bundle for every web worker. Now, in Angular 8 this task can be performed by the Angular CLI.

Also, we can configure our Angular CLI project if we add the web worker for the first time. In this process, CLI will exclude the worker.ts files from the tsconfig.json files and also, add a new TypeScript configuration file named tsconfig.worker.json which handles the worker.ts file. Also, this information also added to the angular.json file as

“webWorkerTsConfig”: “tsconfig.worker.json”

3. Support for typescript-

Finally, Angular 8 is updates to the latest and greatest versions of Angular’s dependencies, which include tools like RxJS and TypeScript. In spite of the fact that this might seem like a small improvement, it’s also an appreciated one. Keeping up with TypeScript, in particular, is great because the TypeScript team consistently appears to pack useful new features into every release. In spite of the fact that there’s nothing preventing you from manually upgrade to the latest version of TypeScript in your projects, it’s great to see that the Angular team is keeping up with everything that TypeScript has to offer and that new apps generated via the Angular CLI will also use the newest version of TypeScript by default.

4. Bazel support-

In new version of Angular, Google introduced another build tool called Bazel. In reality, it is not a new tool. Google used this tool internally since a long time but now, they released this tool as open source. But Bazel is not totally ready in Angular 8. It is introduced as pick in choice with Angular 8 and is expected to be included in the Angular CLI in version 9.

Benefits of using Bazel-

It will provide a faster build time. Generally, It takes time for the first build but taking less time from the concurrent builds.

Using this tool, we can develop the application as an incremental build and deploy only what has been changed rather than the entire app.

We can eject the Bazel file which is normally hidden.

We can add Bazel Support using the below Angular CLI Command,

ng add @angular/bazel

Also, we can create a new app with Bazel with the help of below command,

npm install -g @angular/bazel  

ng new my-app –collection=@angular/bazel  

5. Differential Loading for performance optimization-

It is one of the best new features in the Angular CLI 8. Because with the assistance of these features, we will determine which browser we will target and the CLI will build the application with related necessary JS bundles with the necessary polyfills. The default target browser in the tsconfig.json file is now es2015. This means that when CLI build the application, it will build for the modern browser that supports ES6 features. But, we have to run the application in an older browser like IE9, then we have to specify it in the browser list file. This file exists in the root folder of the CLI project. Previously, it is used for the CSS part only. Now, it can be used for JS generation.

6. Changes in Lazy Loading in Route-

In Angular from the starting, the router mechanism always supports the concept of lazy loading. Till Angular 7, it was done by the string value of the loading module as below,

{  

  path: ‘lazy’,  

  loadChildren: () => ‘./admin/admin.module#AdminModule’  

}

The value up to the #(hash) sign represents the path of the module file. In this the target component exists and the value after the hash sign represent the class name of that module. This style will continuously work in Angular 8. Only the way of writing lazy module has been changed. The string value of the loadchildren has been deprecated because of the support of ECMAScript and Ivy will only support this. So, now the loadchildren declaration will be like this,

{  

  path: ‘lazy’,  

  loadChildren: () => import(‘./admin/admin.module’).then(m => m.AdminModule)  

}  

7. Use Analytics Data-

In Angular 8, Angular CLI use analytics data so that Angular team can prioritize the features and improvements. So, when we update the CLI projects, it will opt-in with ng analytics on options. If we allow this globally, then it will collect some data like command used, the flag used, Operating System, Node Version, CPU Count, RAM Size, execution time and error with crash data if any to the Angular team for the improvement purpose in the future releases.

8. Support SVG Template-

Now, Angular 8 supports the template features with a file extension SVG. This means that, we can use the SVG extension file as a template in place of HTML file without any extra configuration settings. But why we will use a .svg file as a template instead of using the image in an HTML file? The reason is when we use SVG as a template, then we can use that as a directive and as a result, we can bind it just like HTML templates. With this approach, we can dynamically generate interactive graphics in our Angular Applications.

@Component({  

  selector: “app-icon”,  

  templateUrl: “./icon.component.svg”,  

  styleUrls: [“./icon.component.css”]  

})  

export class DashboardComponent {…}

9. PNPM Support-

In Angular 8, Angular CLI also support PNPM including NPM and Yarn. Also, in the command ng add now provide a new flag called – registry for adding packages from any private NPM registry. This command is already available in the Angular CLI version for ng update command.

Conclusion-

These are the new features in Angular 8, that you can use for effective development. If your apps are going to need changes, it’s better to find out immediately than to wait.
