Let us examine the distinction between MEAN and MERN stacks

A great way to fully comprehend full-stack development is to build a custom web application. The distinction between a mean stack and a mean stack must be understood when deciding which technology stack is best for a web development project.

Furthermore, big data advancements have thrust agile methodologies into the spotlight. The infrastructure of modern software programmes must be strong in order to adapt to the dynamic business environment. The stack that maximises flexibility, scalability, and performance while remaining cost-effective must therefore be chosen by developers. They should be fully informed of the advantages and disadvantages of each option before making their choice. But first, let's give beginners an introduction to full-stack development.

Full-stack development: What is it?

In the context of web development, "full stack" refers to the front-end, back-end, testing, and mobile app software systems. Traditionally, businesses hired people with expertise in any of these fields. However, there is a high demand for qualified candidates in ancillary technologies as the needs of modern workplaces change.

Mean Stack vs. Mern Stack

Due to the fact that both frameworks provide trustworthy abstraction at the UI level, the competition between the MEAN and MERN stacks is quite close. While Mern Stack uses the ReactJS library, a Facebook product, Mean Stack makes use of AngularJS, which is supported by Google Inc. By using JavaScript as the main programming language, code switching is avoided, and new developers are given the tools necessary to materialise their concepts.

Both options offer a fantastic set of tools that can be used to create software products that work well. Therefore, selecting the appropriate stack for their applications can be overwhelming for newcomers. Let us examine their advantages more closely and contrast how well they perform in various scenarios.

What is Mean Stack and why should you use it?

One of the rapidly expanding open-source development frameworks, Mean Stack, enables programmers to quickly and easily create complex web applications. The phrase "mean stack" refers to a collection of JavaScript-based frameworks used to create sophisticated web applications. A combination of MEAN Stack technologies, including MongoDB, Express.JS, Angular, and Node.JS, is used in mobile and web applications.

The need for technology has given developers the green light to work on the front-end, back-end, and much more. Today's developers are capable of understanding and resolving issues in a variety of software development streams. Software development firms are now cautiously looking to hire "mean stack" developers who can completely build the website or application from scratch without stopping.

Recent years have seen an exponential growth in web development technologies. Front-end technologies like AngularJS, Node JS, React JS, and others have replaced back-end development technologies like Java, PHP, and others. These technologies have undergone continuous development since their inception in order to increase coding effectiveness and decrease code size. One such group of tools that has significantly cut down on development time is the MEAN stack.

The primary advantage of using the MEAN stack is that all of the coding is JavaScript-based. This shortens the amount of time a novice developer must spend learning. A lightweight application architecture and a quick turnaround time have also become essential due to the global boom in the start-up culture. MEAN Stack aids in meeting this requirement. The JavaScript engine used by the entire programme, including the web application server, is based on Chrome. This decreases the overall amount of memory needed and speeds up web response time.

In addition to the advantages listed above, the MEAN stack has lower development costs. Additionally, MEAN.JS is completely open source and free to use, as is its extensive ecosystem. Because of its sharing capabilities, which make extensive code reuse and sharing within the stack possible and lower overall costs. It might be one of the main advantages of using MEAN for business. The development time can be shortened, resulting in a lower development cost, thanks to its unified and flexible offerings.

The MEAN stack also aids in scalability and quick MVP development. A productive platform for creating scalable software products is the MEAN stack. The stack contains a sizable number of additional frameworks, libraries, and reusable modules that enable businesses to accelerate development more effectively. Therefore, MEAN stack can be a great option for start-ups due to its shorter development cycles and lower development costs by helping to deliver modern and ready-made solutions, which can significantly save time while making development less strenuous.

Here is a brief description of the mean stack components:

AngularJS is the front-end framework that runs the code in the user's browser.

NodeJS is a runtime system that implements JavaScript on the backend of a web application.

ExpressJS is the back-end application that runs on top of NodeJS.

MongoDB: It is used to store the data of back-end applications as JSON files.

MERN: Why?

The MERN stack's main selling point is that it is a platform that offers businesses and enterprises the agility, performance, and intelligence they require to advance their operations. JavaScript is at the core of many technologies that enable developers to build and deliver websites with rich experiences similar to desktop and mobile apps because all web users today demand high levels of performance and interactivity.

JavaScript has evolved into a web interface. It has changed significantly over the years. Today, JavaScript is used for much more than just adding visual effects to websites; it also aids in the implementation of application logic and database access.

Due to a few benefits, MERN Stack is also securing a small place in the world of the software developer. There is no need for context switching because every line of code is written in JavaScript. In traditional tech stacks, the challenge for developers was figuring out how to integrate different programming languages into one another in order to turn their ideas into usable products. But compared to earlier times, the present is a significant departure. As the JavaScript stack has improved, things are now more balanced. Developers can only use JavaScript and JSON when using the JavaScript stack (JavaScript Object Notation). Additionally, this stack excels at creating highly effective web applications.

No templates exist for the language. React is a popular programming language despite not being one of the hottest or most in-demand ones because it lacks templates. React is sometimes more frequently used by web developers than other languages because it eliminates the need to learn and practise a templating language in order to automate the process of creating repetitive HTML or DOM elements. React creates repetitive or conditional DOM elements with the help of a fully featured programming language, which is none other than the internet's ancestor technologies. Indeed, JavaScript.

Therefore, it is obvious from the aforementioned shifting trends that the world of web development is a dynamic one. Although selecting the most renowned and ideal frameworks, technologies, or, should we say, the stack, may be challenging, we can always try to select the stack that best meets your company's needs.

The following elements make up the Mern stack:

ReactJS is a library that facilitates creating the user interface components of single-page web applications.

NodeJS is a runtime environment capable of running JavaScript on a machine.

ExpressJS is a layered framework built on top of NodeJS that takes care of the website’s back-end functionality and structure.

MongoDB is a document-oriented NoSQL data store.

MEAN vs. MERN stack: A tight race

Because of its MVC architecture, the AngularJS framework is already well known among AngularJS developers. MVC architecture, however, might not always be necessary for a web application. Some web applications might only require a UI layer abstraction to optimise the component rendering code. A library that fills this need is React JS.

The use of the AngularJS framework and the React JS library, respectively, is the primary distinction between the MEAN and MERN stacks. Making a decision between MEAN and MERN can be difficult because both frameworks are focused on delivering UI-level abstraction. React JS is a creation of Facebook Inc., whereas Angular JS is supported by Google Inc. As a result, each of them has the support of influential business people. The process of selecting the best technology stack for your needs is covered in detail in the following section.

A conclusion

This article's conclusion follows the discussion of mean stack vs. mean stack. To summarise, we learned about full-stack development before learning the difference between mean stack and mean stack. In this overview, we focused on the benefits of using each technology stack before recommending the best choice in a variety of situations.

Operating along, these software system programs helps to change the online development method. The core strength of MEAN stack is in its centralization of JavaScript as its primary artificial language.

Each part during this internet stack is written in JavaScript and therefore the info stores information in JavaScript Object Notation (JSON) format. This implies that JS isn’t solely used as a client-side scripting language however additionally within the entire application, that will increase productivity. Its integral elements include:

MongoDB (data persistence)

Express.js (server-side application framework)

Angular (client-side application)

Node.JS (server-side environment)

MEAN Stack helps to develop apps that ar climbable, flexible, and protrusile, that makes it the perfect candidate for cloud hosting.

What are the pros and Cons of MEAN Stack?

Pros

The main reason why most developers get pleasure from victimization mean is that the use of one language (JavaScript), that permits shift between the shopper and therefore the server easier.

With MEAN, you’ll be able to produce straightforward ASCII text file solutions which may be accustomed develop sturdy and rectifiable applications.

It permits period of time demonstration of apps.

It is cloud compatible. With cloud functionalities turning into Associate in nursing integral a part of fashionable websites and apps, the MongoDB in MEAN permits you to develop, test, and deploy those functionalities with abundant ease.

It’s efficient and time-conscious.

Cons

MongoDB may be ideal for little and mid-size applications, except for large-scale applications, it may doubtless result in loss of knowledge once networking partitioning happens.

Express.js provides poor isolation of server from business logic. This will curtail the reprocess of bound services like batching operations.

It becomes difficult to travel back to the recent approach once you develop the primary website victimization MEAN Stack technology.

Differences between LAMP VS MEAN Stack

A large community of individual and company contributors and sponsors back the technologies within the MEAN Stack and therefore the MEAN Stack itself. There are programmers, experts, everyday people that have worked on one in every of the technologies within the past. Once you are unable to write a nasty piece of code, they’re the individuals you request facilitate from.

Both software system development stacks are about to still play a crucial role within the development of internet applications for years to come back. However, the last word selection for your start-up can come back right down to the use-cases and business priorities for the app that’s below development.

With a powerful wage and tremendous growth opportunities, MEAN Stack is here to remain. Developers during this field usually go on to figure as technical architects.

WEB FRONT END DEVELOPMENT

Everything that you see when you’re navigating around the Internet, from fonts and colours to dropdown menus and sliders, is a combination of HTML, CSS, and JavaScript being controlled by your computer’s browser.

As we have seen All that we see, click and interact on a website is because of front end development.  A site is loaded in a browser from the server in front-end development.  A user sends request to the server. The server sends the response back to the user.  This framework is known as client server framework. Client server frameworks use languages JavaScript, ReactJS and AngularJS. These frameworks have made interactive and mobile responsive websites possible for the users. Let’s have an insight to the Front-End Web Development.

The Client Server Framework

The client is the browser a user uses to view a website using mobile devices, laptops, or desktop computers. The server is stationed at a remote location, running the website’s back-end architecture processing.  Conceptually client-side scripting is done by the web browser, and server-side scripting is done by the web server.

Client-side scripting is always evolving becoming simple, lively and more user-friendly.  Client-side scripts run in the browser and processes requests without call-backs to the server.

Server-side scripting is the back-end web development and main function of it is to connect your website’s database to the browser and bring back a page to your screen providing a smooth user- experience. Server-side scripts process the data, and then update the website. For example, populating drop-down menus, loading products to a page, updating a user profile, and more.

Front-End Web Development

Your website comprises of a sum of layers – structure, data design, content and functionality. All that you click, interact, and customize on a website is because of front-end development.  This user facing functionality is developed by front-end developer. The front-end developer uses a combination of client-side scripts and frameworks, mark-up languages, and designs an environment where a user can experience an aura of content, layout and interaction.

In short front-end development is a powerhouse where creativity and innovation collide.  Front end developers need to be a bridge between the designer and the back-end programmer.

The front-end developer creates interaction and user experience with scripts embedded in a website’s HTML. Everything you as a visitor to your website sees, click, or uses to input or retrieve information is the work of the front-end developer. They are the ones who create client-side software that brings the site’s design to life. Scripts are downloaded by the browser, processed, and then run apart from the server. In front development the main focus of the front-end developer would be on user experience, and the technology they implement will determine how well it accomplishes that speed, efficiency, and smooth functionality.

Skill Sets for Front-End Development

The core technologies of front-end development are mix of HTML, CSS, and client-side scripts namely Javascript.

The core competencies in hiring a front-end developer, lies in his ability to have a broad view of how the front end of the site works and its design.  Added crossover knowledge of SQL, Java, PHP, Ruby, Node.js would be of great advantage to your front-end developer.

The main services of front-end developer include:

•Customize user experience

•Bringing life to designer’s concept with HTML, CSS, and Javascript

•Production, modification, and maintenance of websites and web application user interfaces

•Tool creation enhancing how users see and interact with your site in browser

•Implementing responsive design for mobile sites

•Contributing some back-end experience, collaborating on APIs

•Consulting on best SEO practices

•Testing the site during development for usability and fixing any bugs

Front-End Languages

Since now you might have a brief overview of front-end technology. Let’s have a look at some of the most widely used scripting languages and front-end frameworks. The front-end languages are almost always used in the context of their frameworks, which make quick work of complicated code with libraries of pre-packaged, shareable code, and lots of add-ons. Your front-end developer may use one or a combination of these when during building the front end of your web site.

Front-End Frameworks

Front-End framework facilitates a rapid development with libraries of pre-packed, shareable code and software add-ons.  Some of the popular Java script frameworks are listed below. Your front-end developer can use one or combination of these when building front end for a website.

•Angular JS – This framework and other JS frameworks like Backbone.js, power up the power of Javascript.

•jQuery – This is a fast, small, JS object library, it streamlines how JavaScript behaves across different browsers.

•Bootstrap – This leading mobile-first framework blends HTML, CSS, and JavaScript to influence rapid responsive app development. With Bootstrap, your web site will be compatible with all modern browsers and is screen responsive on any size screen, from tablets to phones to laptops.

Client-Side scripting Development

A path breaking that has changed the hard-and-fast rules for client side vs. server side is the AJAX technology. The old standard was that server-side processing and page post-backs were used when the browser needed to interact with things on the server, like databases. AJAX, with its asynchronous calls to the server, can pull the data instantly and efficiently, without requiring a post-back.

Another major boost is jQuery technology, a fast, small, and feature-rich JavaScript library with an easy-to-use API that works across a multitude of browsers. Like code libraries do, jQuery changed the way that millions of people write JavaScript, simplifying a number of other client-side scripts like AJAX at the same time.

Technology is ever-changing and evolving, it’s crucial to know who to follow in order to get the best advice, tips, and news.  We at WHIZ have a compiled a list of the top front-end developers to deliver excellence. At WHIZ, we have a team of multi-talented and top front-end developers having extensive knowledge and experience in field. Therefore, creating website for your business requirements at our place would be highly competitive and worthwhile.

Front End vs Back End Development: What Is the Difference?

In web development, front end and back end are two of the most popular terms. They are both very crucial and quite different from each other. Each side needs to communicate and operate effectively with the other as a single unit to improve the website’s functionality.  

Front End Development: This is the part of the website that user interact directly with. It is also referred to as the ‘client side’ of the application. It includes everything that users experience directly such as text colours and styles, images, graphs and tables, buttons, colours, and navigation menu. HTML, CSS, and JavaScript are the languages used for Front End development. The structure, design, behaviour, and content of everything seen on browser screen when websites, web applications, or mobile apps are opened up, is implemented by front End developers. Responsiveness and performance are two main objectives of the front End. The developer must ensure that the site is responsive i.e., it appears correctly on devices of all sizes and no part of the website should behave abnormally irrespective of the size of the screen.

Front end languages include:

1.      HTML: HTML stands for Hyper Text Markup Language. It is used to design the front end portion of web pages using markup language. HTML is the combination of Hypertext and Markup language. Hypertext defines the link between the web pages. The markup language is used to define the text documentation within tag which defines the structure of web pages.

2.      CSS: Cascading Style Sheets fondly referred to as CSS is a simply designed language intended to simplify the process of making web pages presentable. CSS allows you to apply styles to web pages. More importantly, CSS enables you to do this independent of the HTML that makes up each web page.

3.      JavaScript: JavaScript is a famous scripting language used to create the magic on the sites to make the site interactive for the user. It is used to enhancing the functionality of a website to running web-based software.

Front end frameworks and libraries include:

1.      AngularJS: AngularJS is a JavaScript open-source front-end framework that is mainly used to develop single page web applications (SPAs). It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML. It is an open-source project which can be freely. It extends HTML attributes with Directives, and data is bound with HTML.

2.      React.js: React is a declarative, efficient, and flexible JavaScript library for building user interfaces. ReactJS is an open-source, component-based front end library responsible only for the view layer of the application. It is maintained by Facebook.

3.      Bootstrap: Bootstrap is a free and open-source tool collection for creating responsive websites and web applications. It is the most popular HTML, CSS, and JavaScript framework for developing responsive, mobile-first web sites.

4.      jQuery: jQuery is an open-source JavaScript library that simplifies the interactions between an HTML/CSS document, or more precisely the Document Object Model (DOM), and JavaScript. Elaborating the terms, jQuery simplifies HTML document traversing and manipulation, browser event handling, DOM animations, Ajax interactions, and cross-browser JavaScript development.

5.      SASS: It is the most reliable, mature and robust CSS extension language. It is used to extend the functionality of an existing CSS of a site including everything from variables, inheritance, and nesting with ease.

Some other libraries and frameworks are: Semantic-UI, Foundation, Materialize, Backbone.js, Express.js, Ember.js etc.

 Backend Development: Backend is server side of the website. It stores and arranges data, and also makes sure everything on the client-side of the website works fine. It is the part of the website that you cannot see and interact with. It is the portion of software that does not come in direct contact with the users. The parts and characteristics developed by backend designers are indirectly accessed by users through a front-end application. Activities, like writing APIs, creating libraries, and working with system components without user interfaces or even systems of scientific programming, are also included in the backend.

Back end languages include:

1.      PHP: PHP is a server-side scripting language designed specifically for web development. Since PHP code executed on the server side so it is called server-side scripting language.

2.      C++: It is a general-purpose programming language and widely used now a days for competitive programming. It is also used as backend language.

3.      Java: Java is one of the most popular and widely used programming language and platform. It is highly scalable. Java components are easily available.

4.      Python: Python is a programming language that lets you work quickly and integrate systems more efficiently.

5.      JavaScript: JavaScript can be used as both (front end and back end) programming languages.

6.      Node.js: Node.js is an open source and cross-platform runtime environment for executing JavaScript code outside of a browser. You need to remember that NodeJS is not a framework and it’s not a programming language. Most of the people are confused and understand it’s a framework or a programming language. We often use Node.js for building back-end services like APIs like Web App or Mobile App. It’s used in production by large companies such as PayPal, Uber, Netflix, Walmart and so on.

Back end frameworks include:

The list of back end frameworks includes: Express, Django, Rails, Laravel, Spring, etc.

The other back end program/scripting languages are: C#, Ruby, REST, GO etc.

The pages were static around the start of the web and dependably wealthy in the two pictures and records. More than 12 years sooner, Steve Jobs from the outset dispatched web applications that appear and work totally like near to applications. In 2005, Ajax made it possible to make snappier, better, and more instinctual web applications.

In spite of the way that we can give that web application development in 2020 has showed up at its peak of detachment, web applications are so far normal to the point that they regularly go unnoticed. Regardless, people use them for the most part. Web applications engineer the remarkably arranged appreciation of near to applications with changed approval on a website program from any contraption.

Would you like to build up a web application? By that point, this is a definitive manual to help you with each aspect of the web application development, from the significance of the improvement framework.

Web Application Development: All You Need to Know

Web app development is the procedure of creating a web application. It is more about interacting with the browser than the standard engineering procedures. Maximum cases of web app development engage defining the issue, involving with users, mocking-up the solutions, choosing a framework or the tool, and ultimately developing and testing the web app – in maximum cases, repetitively with users.

What is a Web App?

The web application is a type of app that can be used just through the website browser. This app runs on remote servers just when you connect to the internet. Hence, this app is client-server software that enables users to connect with a web server through a browser.

Web Applications vs. Mobile Applications

As you have already read the aforesaid definition of a web app, you can assume that mobile apps and web apps are quite similar kinds of software. Nevertheless, these two are slightly different as well. Mobile app development is exclusively made for mobile gadgets and suitable for a specific platform like Android, iOS, and Cross-platform. Web apps cannot be used without the internet. You can download a mobile app from an app store that acquires space on your device whereas the web apps function in real-time in a web browser with the CPU resources.

Web Applications vs. Websites

The basic difference is our ways of interacting with one another. Web apps are described by their input – we develop, read, upgrade, and erase data inside a web app. On the other hand, websites are described by their output – we read the marketing data, news, and FAQs on websites.

Progressive Web Apps

PWAs or Progressive Web Apps are the latest kinds of web apps that behave and often outperform like native apps. Check out the difference between native apps and Progressive Web Apps. These web apps follow a little different tactic and engage an extra set of technologies like push notifications, manifests, service workers, etc. Progressive Web Apps is just like a ready to access a website that you can save on your home screen, without downloading it. It can be accessed anytime you want in just one click.

Technology Stack of Application Development

Here are some of the web app development technologies that enable you to create an advanced, high-performance, and fast web app:

1. Front-End Technology

To develop a web app’s public part that the users interact with, you should choose some extremely efficient front-end JavaScript frameworks like:

AngularJS – Google’s popular frontend framework that is suitable for dynamic web apps utilizing HTML for static website pages.

ReactJS – One of the strongest and the most famous JS framework utilized for developing large-scale and complex dynamic web apps.

VueJS – A new JS framework made for amazing applicability. It offers an ecosystem of assisting libraries and an accessible primary library, which are utilized for applying large complex single-page apps.

2. Databases

MySQL is the leader among databases utilized for web application development. Multi-functionality and simplicity are its prime benefit. PostgreSQL and Oracle are other good choices. PostgreSQL is an open-source, free database management system based primarily on UNIX-like systems. Oracle leads in the market of strong corporate, commercial databases and is increasing its impact actively on the worldwide network.

3. Backend Technology

Python has taken the most powerful positions in the backend web app development using the framework of Go, Ruby, Node.js, Java, and Django. Every framework and language is precise when it fulfills the aspects of the allotted task. Here are some examples:

Django & Python– Python programming language covers backend web development. It replaces PHP. Python is lightweight, flexible, advanced, and has a low learning curve. Together with Django, its framework, Python can meet all backend web app building tasks.

Node.js – This non-blocking runtime, fast, easy, and modern environment is designed to develop fast and lightweight apps. Enabling fast servers and running software on several hosts are other perks of Node.js.

Ruby – Ruby can feature an active community due to which it has amazing open-source dependencies and great documentation. Moreover, coding is easy in Ruby.

Java – Java is also a multi-purpose programming language. It is utilized in Android app development, desktop development, and web app development. This framework is mostly known for its security and stability.

Web app development is a trendy method that will gain popularity in 2020 and more years to come. Organizations and users prefer web apps for their extensive array of functionality, great interaction, and amazing performance. By enabling your future web app with some cool solutions and features, you will also make sure that the product provides a huge base of clients and users, and stays high in demand for over a year or even decade.

When you are implementing several technologies, deciding on the right technological stack for your business is not an easy task. By enhancing your technological infrastructure, it always puts you in minor setbacks. However, you are required to do quite often, and you cannot escape that. There are various database architectures and software solutions available, and you are not aware on every one of them, so you can’t figure out which solution to go for and why.

So, in this article, we’ll brief you about the two technology stacks to choose from for your ongoing business. But before you start comparing the differences of each technology stack, you need to understand the attribution and feasibility of stack which is very crucial in development as well as product solutions.

Here are a few aspects you need to take care before choosing the right stack for your project :

1 – Know your project requirement

2 – Shift to Agile model

3 – Go beyond your project requirements for better user experience

4 – Experience and knowledge of development team

5 – Flexibility and Scalability of the team

6 – The cost of development

Let us try to understand the differences which will make you easier to decide the correct technology stack for your project.

Introducing LAMP Stack development

LAMP stands for Linux, Apache, MySQL, and PHP, Perl or Python. It is one of the earliest stacks in web development and well suited for dynamic websites and web applications. It is still implemented as it offers great substitute to commercial Software packages.

As LAMP stack is opensource it allows developers to avoid vendor lock-in and develop for the web without having to spend much towards their development. For many years, it has been a compelling solution to develop enterprise level web apps with advanced customisation and flexibility. LAMP interacts with end users and source can be altered to suit the specific needs of the developer.

Benefits of LAMP Stack Development :

1 – Easy to Deploy :

The deployment factor of web application is tough especially when the programming language cannot easily be integrated with database and server. However, in LAMP no such issues occurs as it implements PHP which makes it feasible to expand LAMP web apps.

2 – Cost Factor :

As every level in LAMP stack is open-source, a project can be completed with minimum development and hardware costs.Moreover, there are other opensource projects available in LAMP stack such as Joomla, Drupal, OS Commerce, so you can choose a suitable option and deploy a project based on your requirements. This brings the project cost further low.

3 – Platform independent :

LAMP code works on wide range of operating systems and therefore it is platform independent. LAMP works on Windows, Linux, Android, and iOS easily.

Introducing MEAN Stack development :

MEAN Stack is a collection of Javascript-based software stack applied for building dynamic websites and web applications. MEAN is an acronym where M is MongoDB, E for Express.js, A for Angular JS, and N for Node.js. It is a free and open source stack designed to provide developers with a fast and organized technique of creating rapid prototypes of MEAN based web technologies.

One of the major advantages is the same Javascript language that runs on every tier of applications.

Benefits of MEAN Stack development :

1 – High Flexibility :

MEAN stack enables efficient development of isomorphic code as it implements Javascript all through. For instance, if you develop a code in Node.js and later if you plan to move your code to AngularJS you can easily do it without altering anything within the code.

MongDB itself enhances the flexibility of MEAN stack.It is a rigid database layer with automatic sharing and full cluster suport functionalities.Hence, you can host your project on cloud.

2 – Advantage of JSON :

MEAN stack development can be beneficial for with JSON. When you choose Angular JS or MongoDB it allows seamless data distribution between the layers. The data can be imported with the help of codes from MySQL server and process it.MEAN stack uses similar formats each time so when reformatting, it saves time. It also supports external APIs, so that you can choose to work with them when needed.

3 – Rapid MVP development :

A lot of frameworks, libraries, & reusable modules are available within the stack which increases the speed of development. With ready-made solutions, one just not only saves time but also makes the development less laborious.MEAN stack also offers a robust foundation to build scalable software products.

Comparison of LAMP Stack and MEAN Stack

Performance :

The database of stack is most responsible for performance and speed.With MySQL database, the app frequently suffers from high transaction loads bringing down the loading speed and overall performance.

In contrast to MEAN stack MongoDB is incredibly fast by trading off consistency it enhances the performance.MEAN stack is an ideal choice when a project can afford data loss once for achieving speed and flexibility.

Databases :

MySQL, the database layer of LAMP stack is a conventional database system which lacks optimization for fast-paced app development with quick response rate and flexibility.

MEAN stack allows you to work on a single non-relational database – MongoDB. It does not store data in tables rather it features a document-based query model. Nowadays developers prefer MongoDB in comparison to relational databases to accelerate and secure data easily.

Front-end and Back-end Development :

With LAMP stack you need to hire javascript developers for building Frontend apps while for backend you need PHP or Perl developers. In addition to this LAMP stack comes with various layers of navigation to access different configuration files and to use different syntax while programming.This makes the development complex and slower.

In case of MEAN stack development, you just need a Javascript developer for programming both frontend and backend as its all Javascript across the stack.

Scalability :

LAMP stack involves MySQL database with lot of requests and high concurrency rate the performance of MySQL slows down. With lower input and output ratio it performs better but when the ratio is scaled up the performance becomes sluggish.

In the other hand, MEAN stack has superb advantages with respect to scaling of performance with number of inputs growing up.As the rate of concurrency increases, the stack is able to scale up the database, frontend and backend.Apart from this, MongoDB provides support to auto-failover and auto-sharding to distribute the data uniformly with automatic rearranging. This aids in scaling up the performance as the number of requests rises.

EndNote :

Your game changing ideas need top-notch execution. It’s essential to indulge yourself with partners who will deliver a great product according to your requirements that results in significant ROI. Many enterprises realised that LAMP stack is not flexible enough to serve their purposes, so they are gradually moving towards MEAN stack and its high time you should too.

Deciding the right technology stack between LAMP and MEAN stack development is crucial to achieve your desired results.At the end, software built on right technology results in better performance, easier integration, faster development and increased satisfaction of your clients.

Well, you’re just one step away. Fortunesoft IT Innovations specializes in providing MEAN Stack development services. Contact us to discuss your project today!

Front End Development vs Back End Development

  Author  : Pooja S

   Two terms thrown around a lot in web industry are, front-end and back-end. It can be little frustrating since the difference between the front-end and back-end isn’t always perfectly clear. The front-end is also referred to as the client-side  and is sometimes considered “web design”. The back-end of the web industry is often called the server-side.The differences between design and development actually lead to more of a discussion around frontend and backend web work.Let's start with the frontend...

Front-End Development:

   The front-end is everything involving with what user sees.The front end of an application is the visible part of it that the user interacts with. The main purpose of the front end is to deliver effective interactivity and display of the content and data in an appealing, neat and simple to understand manner. 

Let’s talk about some of the technical skills ,tools and knowledge base required for front end development:

1.HTML:

Web pages are created by using a markup language called Hypertext Markup Language(HTML).It ia a language that is easily understood and interpreted by web browsers,and is widely used to showcase content to users.HTML and its latest version HTML5 are widely used for creating webpages.

2.CSS:

Cascading style sheets (CSS) complements HTML by providing the styling required for an attractive interface.CSS is required for the effective presentation of the webpage.

3.Javascript:

It is a dynamic programming language that is used to add interactivity to web pages,process data,as well as create various applications(mobile apps,desktop apps,games and more).It makes possible the integration of multimedia on the web page or the app page and features,such as drag-and-drop,polls,quizzes etc.It is an interpreted programming anguage with object-oriented capabilities.

In addition to fluency in these languages ,front-end developers need to be familiar with frameworks like Bootstrap,Foundation, Backbone,Angularjs and emberjs and libraries like jQuery.

Back-End Development:

The back end or the “server-side” of web development basically comprises of three components: server, application and database.

     These are the scripting languages used in back-end programming:

1.PHP:

 PHP(Hypertext Preprocessor) is a widely used open source general-purpose scripting language that can be embedded into HTML,which means when the code is run on the server, HTML is generated which is sent to the user.

2.Python:

Python is a programming language which is widely used forits readability and syntax.A popular web development framework,Django,also makes Python a popular choice for building web applications.

3.Ruby:

Ruby is a dynamic,open source programming language with afocus on simplicity and productivity.Ruby has an elegant syntax that is natural to read and easy to write.

Some of the Database management systems used in back-end:

1.SQL:

Structured Query Language(SQL) is a universal database query Language.It is used to interact with databases,which are a part of every backend web application.

2.MySQL:

MySQL is the most popular database management system used with PHP.With its proven performance ,reliability and ease-of- use,MySQL has become the leading database choice for web-based applications,used by high profie web properties including Facebook,Twitter,You Tube,Yahoo! And many more.

     This blog is just a small part of a big sea called web development.I hope this helped many of you get clear on when people are talking about the front-end and the back-end of the web development.

 Here are some links, which may help you to learn languages required for front-end and back-end development:

Frequently asked questions of programming.

• Should I learn Python or JavaScript? • Data Science vs Web Development vs App Development, which one should I choose? • Why should I learn Web Development when there are popular Web Developing tools like Wix & WordPress? • All these points made me confused 😕 about what should I do?

So before starting with the questions Here's something about who I am and What makes me qualified to answer such questions? I'm a gradiot (an idiot who did his graduation and who has wasted money and time getting zero skills from college while there's an actual opportunity to learn everything online for free). Yes, I am a CS graduate. I have a great desire to make things, you might know the feeling of IT'S ALIVE if you have developed anything. During my college years I came across multiple technologies from Arduino to Raspberry pi, from PHP to JavaScript, Python, flutter you name it. I tried to learn and understand various technologies not due to college curriculum, but due to my desire to learn more and google 😎. Throughout my journey I encountered many questions and here are some of the questions I think will help you guys. Hope You'll like it.

Should I learn Python or JavaScript?

Before I start with why Python🐍 or JavaScript⚡. Let's talk about programming in general. Programming is a way of thinking and implementing the logic you create in a language that machines understand. Now there are styles or you can say structures of programming aka programming paradigms like Object-oriented programming (OOPs), Functional programming, procedural programming, etc. As a developer, you should at least know one of these paradigms. The more paradigms you know the broader choices you'll have for creating efficient and flexible code.

Back to the topic, Python and JavaScript both support OOPs and functional programming along with other paradigms. JavaScript is considered as the king of web programming that is used to create highly functional and dynamic websites. It has a vast ecosystem of libraries and frameworks to choose from like ReactJS, Angular, and Vue for front-end and NodeJS for the backend. You can also create native Apps for phones using React Native in JavaScript. So, with JavaScript, you can develop full-fledged websites as well as mobile applications. Whereas, Python is Best-suited programming language for Machine learning and data science. It has multiple Libraries like Keras, TensorFlow, Scikit-learn, etc. Along with that, Python is easy to use and has large community support. You can also create websites in python using frameworks like Django and Flask. You can also create apps in python as well using Tkinter, kiwi, etc. Both languages have powerful rounding development.

TL;DR Here is my perspective on this topic. As a developer, everyone must know basic web development since Machine learning and Data Science is a service-based skill While Web and App Development is a product-based skill. Hence, Data Science and Machine learning people are called engineers and not developers. Notice the very subtle difference between an engineer and a developer. Also, you know Mark Zuckerberg, Elon Musk, well they started with web dev and created their products. Ask yourself what you want, define your goals, and then choose wisely and always bet on JavaScript.

Data Science vs Web Development vs App Development Which one should I choose?

If you are reading this, you might be knowing very well the pay of a Data Science and ML engineers as compared to a Web Developer or an App Developer. All this huge burst about AI is the future and might very well draw you towards thinking that even I should learn Data Science for a huge package and a job opportunity. Here's the ugly truth, it's hard to get a job in Data Science since companies will prefer a person having the Domain knowledge and usually majoring in Mathematics and statistics, you should at least have Masters or Ph.D. for getting a job in this field. For Example- A fintech company will choose a CFA or Finance major rather than a CS engineer and teach them Data Science since python is easy and it's the efficiency that counts. So, the person with finance knowledge is well suited for the job. However, As I said It's hard to get a job, not impossible. Some CS grads have got into data science and are earning handful. All you need to learn is python and some libraries and mathematics. Now, As I said before, data science is a service-based skill you are not technically a developer you're an engineer who is figuring out solutions for a given problem. On the other hand, being a web or app developer means developing products. You can create applications and websites and release them to earn using ad revenue, selling them, or even creating and maintain them for companies that way you don't have to rely on companies to give your services. I suggest you to first, learn web development and then Data Science while earning through your web dev skills. That way you will have a decent skill set, portfolio, and a budget to start experimenting into the world of machine learning where processing power is everything.

Why should I learn Web Development when there is a popular Web Developing tool like Wix & WordPress?

WordPress and Wix are popular content management systems. They are best for creating small websites and blogs. Yes, they made it easy for anyone to create websites but that doesn't mean web developers' jobs are gone. You can't create Amazon, Netflix, Twitter, and large fully functional websites using them. So, if you are trying to be a low-level web developer, you can pretty much say goodbye to developing websites. You can google top trending tech skills in demand and you will find AngularJS, ReactJS, NodeJS developers in demand. Not only websites but you can also create native applications for android and iOS using React-native and games using ThreeJS a JavaScript library. Possibilities are endless, all you have to do is START. I'll suggest you start with MERN stack just my personal opinion but you can research and pick whichever stack you like.

Is NodeJS better than Django?

Before comparing let's talk about what is NodeJS and Django. Node JS is a JavaScript runtime taken out of the client-side browser environment which uses OS binding for I/O, and Django is a Python framework. So comparing both is like comparing apples with oranges. Though let's have these points clear. When It comes to performance, Yes. NodeJS is faster than Django or in general python since it's written in C++ and is a JS runtime. You ask why? because JavaScript is faster than python because it works on an asynchronous non-blocking object model. When It comes to scalability, No. Django or python, in general, is highly scalable as the caching of applications is quite easy. Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. With the introduction of npm which stands for the Node Package Management system, the open-source community has been boomed towards NodeJS since managing packages and dependencies has never been that easy. Also, npm is far better than pip when it comes to package management, you can research about it. Here are some of the big fishes and the backend tech they preferred for their development. Uber, Twitter, eBay, Netflix, Duckduckgo, PayPal, LinkedIn, Trello, Mozilla, GoDaddy are some big names using Node JS as their backend technology. Pinterest, Instagram, Eventbrite, Sentry, Zapier, Dropbox, Spotify, YouTube are also some big names using Django as their backend technology. Notice the trend here, Uber, Twitter, and Netflix are some of the applications that priorities performance whereas Pinterest, Instagram, YouTube requires a lot of space and thus scalability is their priority. So, the choice is upon you what you want scalability or performance.

All these points made me confused 😕 about what should I do?

First, ask yourself what do you enjoy doing. Do you like to create games, apps, websites? What intrigues you? What sparks your curiosity? I have listed some of the questions depending upon the choices you make.

• GAME Development – If you want to get into the game development industry, you will have to learn C# or C++ for hardcore game development. You can create web games using ThreeJS or any other library but you won't be exactly a game developer.

• App Development – You can create an application using JAVA for android or Swift for iOS. Further, you can use React-native or Flutter for creating apps that would run on both android and iOS. If you want web apps, you can use Ionic as well.

• Web Development – There are many stacks (a set of technologies that suits well with each other) you could choose to learn like MEAN stack, MERN stack, LAMP stack, etc. You can create a website from WordPress or Wix as well. Develop an interactive portfolio for yourself with the stack you find interesting.

• Data Science, ML, AI – Start with python and take courses on data science, mathematics, machine learning, from popular websites like Udemy or LinkedIn. Start competing on Kaggle and maintain your Kaggle profile. Second, do yourself a favor and start learning algorithms and data structures in the language that fits your answer to the above question. Third, Start applying for internships with some projects and try to make an exemplary portfolio. Maintain your GitHub, LeetCode or HackerRank or any other profiles which you can include on your resume.

I hope this might help you; I tried my best to answer some of the questions that I've faced throughout my journey as a gradiot. If you feel that I'm missing something or something is wrong please feel free to correct me in the comment section. Thank you for your valuable time.

Is the MEAN Stack the best technological stack for your Web Application Development?

Every web or enterprise application needs certain technology (like programming languages, frameworks, platforms) or technology stack to develop it based on customer needs.  

The technology stack is enclosed with many languages and frameworks as one list, to build a particular application. There are billions of websites and web apps are hosted and used by the people. Hence the demand for developing web app is raised along with the increasing use of technology stack.  

In this, MEAN is one of the popular technology stacks that is trusted by a strong developer community to build web applications. We will discuss how this MEAN stack is useful for your web application development.

MEAN Stack

MEAN is a JavaScript-based technology stack for building websites and web apps that are dynamic. A stack is a set of elements grouped to perform particular functions on app development. MEAN applications can use one language for both server-side and client-side environments as they support all programs in JavaScript. So, it is an added advantage of using the MEAN stack for your web applications. Also, Java Script is the most preferred programming language for web development.

MEAN Stack Application Architecture

MEAN comprises of MongoDB, Express.js, Angular, and Node.js. All these Java Script environments are popular among the developers. So, individually, each one contributes its features to build a web application or website. But MEAN stack (all together) will benefit you in a lot of ways which we will discuss later.

The architecture of the MEAN is well explained by its four components (i.e.,) MongoDB, Express.js, Angular, Node.js. Let's see the components below:

MongoDB

MongoDB is a database for storing data. Using JavaScript as a query programming language, MongoDB stores any size data without causing interruptions in the stack. It is a cross-platform data storing system. Therefore, the website or web applications can use MongoDB for saving all the data in the app as it is also enclosed with JavaScript.

Express.js

Any application development includes front-end (client-side) development and back-end (server-side) development along with the database to control the data.

Express.js aka Express is taking care of the back-end development of the MEAN stack application. It is a web application framework for Node.js that serves fast and secured web apps and also helps to make the development process simple and easy.  

Angular

AngularJS is a popular front-end (client-side) framework for developing web applications. Built by Google, AngularJS is the most used framework by the developers. The Angular js (the first version) is upgraded to many new versions like Angular 2 to Angular 9, and Angular is still in the process because of its modularity. It provides many modules for a single application.  

Many large companies like Google, Amazon, Apple, YouTube, PayPal, etc., are using Angular in its technology stack. This shows the popularity of Angular.

Node.js

Node.js is a runtime environment based on JavaScript for developing faster applications. As an opensource and server-side (back-end) platform, Node.js is used to build scalable applications.  

As per stats, 28,000 websites are using this Node.js platform. It serves as a backend for many popular business websites like eBay, AliExpress, etc., So, Node.js is also one of the most used environments in the JavaScript language and hence it is the best part of the MEAN stack.

Working Process of MEAN Stack

Thus, these four components complete the MEAN stack architecture with the following working process:

Step 1: Whenever the client requests in the application, it hits AngularJS as it is the client-side framework.

Step 2: This request from AngularJS passes into Node.js, the back-end environment through the Express.js, a web framework for Node.js.

Step 3: Express.js then allows the request to reach the database

Step 4: MongoDB, where the database is controlled, accepts the request and sends the response to Express.js.

Step 5: Finally, from Express.js to Node.js and from Node.js to AngularJS, the response will reach the user.

These steps will help you to get secure and faster web applications. Hence using the MEAN stack is a good choice.  

Reasons for Using MEAN Stack for Web Applications

Now, we will discuss the reasons for using this MEAN stack in detail. These benefits will help you to understand how the MEAN stack is useful for developing web applications.

Don’t overwhelm with multiple programming languages

As already said, one of the important advantages of using MEAN stack is to use a single programming language that is JavaScript. Since JavaScript is applicable for both front-end and back-end development, the MEAN stack developers find it easy to implement this technology in the app development. This one simple language will help you to save time without focusing on multiple languages.

Develop flexible applications

Another important point in the MEAN stack is its flexibility feature. Due to the higher flexibility in MEAN stack, it can be helpful for a single app to enterprise app development. This flexibility is not only useful in development part but also plays a vital role during the testing process. Adding an element is easier in the MEAN stack process.

See better performance in the apps

As the MEAN stack’s four components (from MongoDB to Node.js) provide various individual benefits, together the MEAN stack web application is developed with high performance.

MongoDB will add any new element easily by controlling the database. Express.js is well worked with Node.js.  

Since Node.js is providing optimal performance than existing platforms, Node.js can run in different operating systems easily. Also, the front-end part, Angular is taking care of testing, reusable code, etc., In simple, Node.js and Angular is a powerful pack of MEAN stack frameworks that improves the performance of the application.

JSON is being used

JSON or JavaScript Object Notation is used in both AngularJS and Node.js. JSON is a kind of file or data interchange format that is used in MEAN stack to exchange the data without issues in all layers of the application. This is an added benefit.

Cloud compatibility and integration

MongoDB in the MEAN stack is a needed part as it helps you to host the applications in the cloud easily. MongoDB is the best choice for cloud-based technologies. Also, the four components in the MEAN stack are available free, it helps in reducing the development cost and memory. MongoDB helps in reducing disk space costs by providing better cloud solutions.

Isomorphic coding is integrated

With the help of isomorphic coding and MEAN stack features, transferring code from one framework to another framework is made easier. It is a top feature for web application development. This isomorphism feature is the best part of this stack helping application to be reliable.

High speed and cost-effective

As the title says, MEAN stack is completely helpful in building high-speed applications. Since the components are free and open-source, app development is inexpensive when compared to other technologies.

These features and benefits indicate that MongoDB, Express.js, Angular, and Node.js (MEAN) are the best technology stacks for building your websites and web applications.

MEAN Stack Examples

Most of the large-scale companies include MEAN in its technology stack. Now, we will see the MEAN stack real time applications. These applications are built with Angular and Node.js, the part of the MEAN stack.

YouTube

Forbes

Tumblr

Flickr

Facebook

WhatsApp

Instagram

Netflix

Paytm, etc.,

Due to the user-friendly features in the MEAN stack like cost-effective, single programming language, better performance, and security, the above listed platforms are using this MEAN technology.

I hope these MEAN stack sample applications give you some idea to build your web apps or websites.

MEAN stack vs MERN stack

MERN stack is similar to the MEAN stack where the only different component in MERN stack is, Angular (‘A’) is replaced with React (‘R’). React is also a framework for developing User Interface (UI) of the web applications. React is also based on JavaScript.

For developing small applications, the development time of MERN stack is lower when compares to MEAN stack. Thus, for the small apps, MERN stack is better. But for building the large enterprise applications like your business web apps, MEAN stack is applicable as it provides more features beyond MERN stack.  

Simple Difference Between Full Stack and Mean Stack Development:

A lot of you get confused about the terms full stack and mean stack. Let’s break the confusion with a simple definition.

Full-stack app development is the complete process that includes the development of the front-end and back-end of an app. This app development may include many programming languages and frameworks like JavaScript, PHP, Python, Angular, .NET, etc., From this, you can choose the best technology that satisfies your app requirements.  

Whereas, MEAN is the technology stack used for building full-stack web applications. So, without using two languages like PHP, Python, you can use this MEAN stack for your app development as it is based on single language, (i.,e) JS.

Final Words:

MEAN is the best technology stack to create websites or web applications. So, without wasting time in using multiple languages and frameworks for your application, you can give a try to this MEAN stack as it has many useful advantages to enhance your app features.
