#Ember CLI

[screwdriver-cd]

Release July 2024

It’s summer! The Screwdriver team is pleased to announce our newest release which brings in new features and bug fixes across various components.

New Features

UI

Display admins on pipeline options page

API

Skip execution of virtual jobs - A job can be marked as virtual by adding the annotation screwdriver.cd/virtualJob: true. These jobs will not be executed while processing the workflow for an event, but will proceed with SUCCESS status. These jobs will skip queueing and execution and builds of its downstream jobs will be immediately created to continue the processing of the workflow.

Get repository data from scmRepo without GitHub access - Before this change, extra calls were made to GitHub to fetch SCM repository information. After this change, the API now will pass scmRepo info directly in order to avoid extra GitHub calls. This has been implemented for webhooks only so far.

Pipeline template enhancements: Can customize image, settings, environment, and requires for jobs that already exist in pipeline template, Add new jobs that are not part of pipeline template in user yaml, Flatten shared steps to jobs in pipeline template, Pipeline template validator shows extended configs for job template, Pipeline template validator shows workflow graph

Store

Replace jwt expiration with a config and environment variable - The jwt expiration is currently 13h and is written directly in the source code. This makes it difficult for SD administrators to change to arbitrary values to suit their use cases. Now Screwdriver cluster admins can set the JWT expiration length using JWT_MAX_AGE.

Add handling for the Expect header at onPreAuth - To reduce unnecessary retries when uploading large files, Screwdriver will use the Expect: 100-continue header. The content length can be checked before the body is uploaded. Thus, the HTTP client (store-cli) can receive a 413 error earlier without unnecessary retries.

Bug Fixes

UI

Show workflowGraph for pipeline template validation

Show missing fields in pipeline template detail page

Add test for parameter-utils

New V2 work: Use unified modal style for toggle job modal, Refactor parameter flattening to generalized util, Refactor graph rendering logic, Add v2 secrets route, New confirm action modal UI, case where there are no parameter groups to expand, Clean up the new v2 layout, Refactor pipeline secrets to not use ember data, Refactor to no use ember data for pipeline data, Screwdriver style mixin for Bootstrap buttons, add options to v2 route, Modal for adding a pipeline to a collection, new pipeline header component, Expand default modal styles, Update add to collection modal

API

Add logic to switch to using current user’s SCM token next

Fixed error handling of external trigger

Fix event where a restarted join build is run

Check original job is not archived

Handle API functional testing

Internals

Allow colons to be used in root directory

Allow to cd to rootDir containing special characters

Compatibility List

In order to have these improvements, you will need these minimum versions:

API - v7.0.162

UI - v1.0.967

Store - v5.2.0

Queue-Service - v3.0.10

Launcher - v6.0.200

List of Top JavaScript Frameworks 2020 For Front End Development

JavaScript is defining the future of the tech world with its wide genre of competent frameworks, which are capable of accelerating the development of applications in many ways. How to choose a certain framework in JavaScript is based on the company’s goals, project requirements and how certain frameworks can be used in different scenarios.

JavaScript, one of the most surreal and beautiful programming languages, enwrapped by the intriguing fact that even though it is named “Java” Script, it doesn’t have any association with Java. In mid-1995, when JavaScript came into existence it was disguised as the name Mocha and later it was named as “LiveScript” and when Netscape and Sun did a license agreement it was finally renamed to “JavaScript”. Nobody had even imagined in its initial form that it would be such a revolutionary programming language and would be entitled as one of the major languages to learn. The world is pacing fast with the ever-changing technology and programming languages being the pillar of technology. JavaScript is surely defining the future with its compelling and competent frameworks.

What are the Frameworks?

In general, a framework is a prototype or conceptual structure intended to serve as a support or guide for the building of something that expands the structure into something useful. According to Wikipedia ” A software framework is an abstraction in which software providing generic functionality can be selectively changed by additional user-written code, thus providing application-specific software.”

JavaScript web frameworks are cheat codes for quick web application development. They serve as a skeletal frame for single page application development and allows developers to worry less about code structure or maintenance and help them in focusing more on the creation of complex interface elements and expand opportunities of JS and plain HTML.

So, Which frameworks of JavaScript are most popular and why?

Below is the list of a few Javascript frameworks:

1. AngularJS- AngularJS is an open-source framework used in frontend and is maintained by Google. It is mainly used to subside and sort the problems encountered while creating single-page applications usually have, as it simplifies both development and testing of such application by providing a framework for client-side model view controller (MVC) and model view-view model (MVVM) architectures. For now, it is known to be the most used JavaScript framework for single-page applications and have the largest community of developers.

2. ReactJS- ReactJS camouflage itself to be JS framework but it is more of an open-source JS library, which has huge names like Facebook and Instagram behind it. React was built by a software engineer at Facebook. In 2011, it was first deployed on Facebook’s newsfeed and later on Instagram in 2012. React Js emerges in an ecosystem of complete frameworks, but it’s just the view. In MVC(Mobile-View-Controller) pattern, React.js acts as “V” and can be smoothly integrated with any architecture.

A fully functional dynamic application can’t be built with React alone. Recently, On April 18th 2017, Facebook announced a new core algorithm of React framework library for building user interface named React Fiber, which is said to be the foundation for future development and improvement of ReactJS.

3. Ember JS- A few years back, in 2015, EmberJs was considered to be the best framework leaving React and AngularJS behind. It does two-way data binding as same as AngularJS keeping both view and model in sync for all the time. Emberjs is commonly used for complex feature-rich web applications and website. LinkedIn, Netflix, Chipotle, Blue Apron, Nordstrom are one of the few of the top names that have incorporated EmberJS.

What works in its favour is that it is easy to learn and have many tutorials online which helps to learn it with ease.

4. Vue.Js- Vue.js is considered to be one of the best solutions for cross-platform development. The development of Vue.Js is considered by taking the best qualities from Angular, React and Ember such as Vue.js offers two-way data binding (same as in AngularJS), server-side rendering (like in Angular2 and ReactJS), Vue-CLI (backbone tool for quick start) and optional JSX support. and all the altering flaws in prior three.

5. MeteorJS- MeteorJS is a free and open-source framework, which is well-equipped with tons of features for back-end development, front-end rendering, DB(database) management and business logic. Being a full-stack platform, it has the quality that its name suggests which is being fast. If you’re looking to rapidly develop smaller, reactive applications on the Node.js platform, Meteor is definitely an excellent choice.

Due to its modular structure, all the packages and libraries can be used at a high pace. In terms of performance, all the changes in the database are transmitted to the UI in the shortest time possible and in conversely with no evident time losses caused by different languages or server response time.

The consideration of a JavaScript framework is based on the company’s goals, project requirements and how certain frameworks can be used in certain scenarios. JavaScript is portraying the whole new depiction of the future of technology as it backs the prompt development and prototyping.

These frameworks and libraries have already reshaped the way how JS collaborates with HTML and CSS to compile views both in browsers and now even on native platforms.

EmberConf 2019 Recap

Now that the dust has settled on EmberConf 2019, I thought I'd take some time to write up my experience and what I learned.

I (@oli) was fortunate to be invited to teach my Broccoli.js workshop this year at EmberConf 2019 during March in Portland, Oregon. I taught a similar workshop last year at the conference and received great feedback, and so of course was more than happy to come back this year with a refresher course. For those unfamiliar with Broccoli.js, it's a JavaScript build system used to compile JavaScript projects, and it makes up the build system for Ember.js. My workshop covered an introduction to how Broccoli.js works and how to integrate with it into your Ember.js application. The workshop this year was another great success with attendees leaving with skills to turbo charge their Ember.js build pipeline.

The conference

EmberConf is one of my favourite conferences, not only because I get to geek out with fellow engineers about Ember.js, but mainly due to the stellar organization by Leah Silber and the amazing EmberConf team. EmberConf places a big emphasis on inclusivity, with no space for harassing behavior or anything that makes anyone's experience unpleasant as is outlined in their code of conduct. It's great to be part of such a welcoming community and the organisers should be very proud of the atmosphere that they foster, I didn't see one unhappy face!

The night before the storm

There was a buzz in the air this year, something felt different. After speaking with Tom Dale at the speakers' dinner the night before the conference kicked off, it was hard not to feel infected by his excitement for the keynote the following morning. Tom Dale and Yehuda Katz are the parents of Ember, it was their takes on the technology of the web circa 2010 that gave birth to SproutCore and what subsequently evolved into Ember.js. From their original mantra of Stop Breaking the Web, to today's JavaScript that you wouldn't dream of writing without a compiler of sorts, Tom and Yehuda have pioneered web technologies for nearly a decade. It's for this reason that when Tom gets excited about something, it's probably worth getting excited about.

Keynote time

Conference day one rolls around, and it's keynote time, the room is packed with 1000 or so people, the lights dim and Yehuda and Tom approach the stage. As is customary for EmberConf, they start off with reiterating that EmberConf is an inclusive conference and if you feel someone looks uncomfortable to go and interject into the situation to disperse it or speak to a conference organiser. I've never seen anyone look uncomfortable at EmberConf — quite the opposite for that matter, which is fantastic.

History

Tom covers a bit of Ember's history, being 8 years old this year, and highlights how much the web has changed since Ember was released. The web has evolved so much in the last 8 years, and Ember has kept up and in a lot of cases spearheaded those changes. Ember was founded on the idea of being a framework to "Build ambitious web applications" and one of the founding values of Ember is "Climb the mountain together" (borrowed from DHH). So the mountain is "ambitious web applications" and we climb it together through shared tools, shipping features, and with big changes we move as a community. This really is a fundamental benefit of Ember, that the shared conventions, tooling, and features avoid bike-shedding over things that we as a community collectively agree on and allows Ember to focus on innovation and new ways of solving common problems in a cohesive manner.

A quick recap of some of the things that Ember has done in the past 8 years:

Things like the six-week release cycle, the RFC process, and engaging in standards and code mods have made it easy and predictable for everyone who uses Ember to upgrade as a community and benefit from all the enhancements that come with that. To that end, the Ember Community Surveys show that the majority of users are on the latest LTS or newer version of Ember.

Using the same tools is also important, Ember CLI allows everyone who uses Ember to use the same build tool, and combined with Addons allows for shared extensions to Ember and the build pipeline and allows for the community to experiment and extend Ember in predictable and collaborative ways. Due to the shared conventions anyone opening an Ember application should immediately feel at home and understand how the app is structured, how the build pipeline works, and how additional functionality can be added through shared endeavors.

Stability & Progress

Frameworks must strike a careful balance with the tension between stability and progress. On one hand we don't want to break peoples apps when they upgrade, but at the same time we don't want that to necessarily hold us back from progress, we must climb the mountain together. As such one must strike a balance between aggressive changes cause community fragmentation and cautious changes that leave Ember falling behind its competition.

During the Ember one lifecycle, lots of aggressive changes were made at the expense of leaving some users behind who were unable to upgrade. Comparatively in the 2.0 release cycle, very few major features landed with most releases saying "No new features are added in Ember core", but focused more on internal non-breaking changes to improve stability and coherence. On that note, the fact that the core team managed to ship an entirely new rendering engine under the hood without breaking existing apps, but whilst simultaneously taking advantage of new technologies and improving rendering performance of over 2x is pretty staggering. The Ember 3.0 release cycle tried to strike a balance between shipping things incrementally whilst keeping an eye on the direction of the whole system, driving towards coherence.

Coherence

Coherence is about how features and APIs interact with one another, and making commitments to stability without designing the entire future. For example it means we don't need to land all the changes to a specific programming model in a single release, we can improve the model in one so that new features can be adopted and peoples lives become easier, and finish it off in another thus rounding out the full model and making the API coherent.

An example of this is the component getter and setter model, and how to get rid of this.get('foo') and this.set('foo', 'bar') within a component and replace them with native JavaScript getters and setters this.foo and this.foo = 'bar' would have in the 2.0 series been held back by not having a good story for the setter and this make an asymmetrical and incoherent API. However in the 3.0 series the decision was made to ship the getter syntax, and continue working on the setter syntax until a good solution had been found, and when it does, symmetry was restored and the API became coherent again. So long as there is a long term goal of where we need to get to, we can get there iteratively without having to land everything at once. This strikes a balance between progress and stability.

Incoherence

The problem with this idea of intentionally making something incoherent for the sake of progress leads to the intermediary state potentially being confusing to developers. This confusion state has been termed "the pit of incoherence", it's the middle point between where we are and where we want to be.

The side effect of this is the idea of "churn", that developers have to continually upgrade their apps and adopt new models and ways of thinking, rolling with the punches if you will. So there needs to be a way to communicate to developers when a set of APIs and features have all landed and are all coherent, that documentation is ready and the set are officially supported by the core teams. Traditionally this would be done by cutting a new major release, but Ember uses major releases to signify things that have been finally removed after being deprecated instead of new features being added. This really is the idea of a major version change, signifying that change have been made without preserving backwards compatibility. What most frameworks tend to do however is bundle end of life features with new features, which makes it difficult to upgrade and developers are faced with not only features being removed, but also having to learn new paradigms for the new major version. As an attempt to solve this, Ember is introducing "Editions".

Editions

The idea is to take a snapshot of the framework as a way of signalling to all Ember developers, to all of the core teams, the Ember community and the wide JavaScript community these points of maximum coherence. Essentially "these features are all related and they all reinforce and complement one another, they've all landed, they're all polished and documented, it's a good time for you to go and adopt these features in your application".

And with that, Ember will be releasing its first "official" edition: Octane. Octane is a snapshot of the Ember framework at a given time when a set of features are cohesive and represent "the new way" of building an Ember application. These features are as follows:

Octane is a snapshot, a "peak" of coherence where the core teams have landed a bunch of great new features and now is a good time for the community to adopt them.

To find out more about Octane, checkout the offical preview website.

Roundup

I think editions is an awesome way of packaging a set of features that together for a cohesive experience, that isn't coupled to a semver major release but allows developers to adopt a complete set of changes in one go, invest in learning the "new" ways of doing things and collectively we as a community move up the mountain together.

With the release of Ember Octane, we have a bright future for the Ember project. This edition really does feel like a fundamental shift in the programming model, bringing itself up-to-date with the JavaScript wider community, whilst also ushering in awesome new features like tracked properties, something no other framework is doing as far as I can see.

I think Tom said it best at the end of the keynote:

"I got into web development in the first place because I wanted to make cool things for my friends, and I really love the web because I could write a little bit of code, save the file and instantly I got that feedback loop and I saw something happening on the screen. A little bit of code gave me something really visual and fun and interactive, and I could share it with my friends and they loved it as much as I did. I want that feeling when I'm building things at work."

And Tom is absolutely right, using Ember Octane really does have that similar feedback loop, it really does feel fun.

You can find out more about Ember Octane on the Ember.js website https://emberjs.com/editions/octane/ or watch the EmberConf keynote (and the rest of the conference) in full here: https://www.youtube.com/watch?v=O3RKLHvpUAI

I personally want to give a huge shout out to all the Ember core team members who have made this possible, bravo 👏

Why do Developers Love Using Ember JS

Ember JS is specifically designed to create ambitious web, desktop, and mobile apps. However, this is not just a single reason why developers love using Ember JS, in fact, there are several other reasons to appreciate and use it as well such as:

It can easily be integrated within the large teams

Developers need to write less code with in-built templates

Ember's abstractions allow developers to focus on what makes your app unique

Enhances productivity and efficiency of the developers

One of the perfect examples of the Ember JS app development is Apple Music — a music streaming service that’s loved by millions of users. Apple, being the most standardized OS with stringent guidelines, accepts the apps developed using Ember JS. What else do you need to get convinced? 

In case you are planning to use Ember for your next project, it is advisable to hire Ember JS development companies with experienced and talented developers. Before that, you should know the reasons why Ember is preferred the most by developers.

1. Ember is the WordPress of JavaScript

Because Ember JS is the newest yet smallest in terms of the user base, the core team of Ember is dedicated towards backward compatibility. Backward compatibility is the property of the system, technology, or a product that allows interoperability with an older legacy system. 

2. Convention over Configuration

Ember is known for its well-defined practices and the way it has been structured. It means developers are given the freedom to focus more on their apps’ functionality and unique features rather than reinventing the application with tedious code. One thing that amazes developers is that there is more building and less blueprinting. It consists of some awesome APIs to built the application at a faster rate. 

3. Ember Templates 

Ember JS consists of some beautiful templates written with Handlebars templating language. Due to in-built templates, developers can save a lot of their time as they need to write less code. The role of templates is to provide features like Outlets, Components, and Expressions.

4. Ember CLI

Both Ember and Ember CLI are entirely two different things, however, both are incomplete without each other. Ember CLI is known as the command line utility that comes with the Ember framework’s software stack. In other words, it can also be defined as a simple visual interface that lets humans interact with a computer’s operating system. The best part is Ember CLI allow the use of tools like LESS and CoffeeScript. 

Wrapping Up

Now when you know the reasons why developers prefer using Ember JS, you can also get started with it. All you need to do a little research about the companies who offer best practices and Ember JS services. Further, provide your team with the application idea you have and get started.

Severus smiled happily at her words. His eyes trailed down to her chest, then back up to her face. He would definitely be celebrating after that test. 

He glanced outside at his bike and smirked, nodding. “Works every time,” he sighed smugly. He took a sip of his margarita, before grabbing another chip. He was so excited to do life with her. He was very much enjoying their date night. They tried to do one every week or so, just so they could have some alone time. If not, they at least did it once a month. He craved these moments with her. As much as they lived for their kids, they did make sure to make time for each other always. 

- - -

Severus perched on the bathtub, just as he’d done last time they were in this position. “Isn’t it crazy how different it feels this time?” Severus chuckled as he rested his arms on his thighs. He watched her take the test, then they waited, idly chatting while they did so. Last time, it had been so tense and silent, and filled with tears and vomiting. He didn’t think it would be like that this time. 

Well, maybe the tears. 

He looked over as it beeped, then gestured for her to do the honours. At the immediate change on her face, he smiled. “We’re pregnant?!” he beamed, moving to pick her up in his arms when she nodded. He hugged her close, then kissed her hard. He had been expecting good news, of course, but it was always best to confirm it. He was so happy. He couldn’t wait to give them a sibling. They would be the best big brother and sister. He wasn’t sure how Ash would take it, but Ember would be over the moon. He wondered how their cat would take it… but he really didn’t care either way. 

He kissed her again as he held her, her legs still wrapped around his middle. He could lift her up a lot easier than when they were in high school. He took his physique very seriously, and so did she. They always worked out together and pushed each other, then got in all their cardio that night. It was somewhat of a ritual. 

He moved her up against the bathroom wall, the test clattering to the floor. He used one arm to hold her up, and moved the other hand down to his jeans so he could undo them. She was wearing pants too, due to them taking the bike, so that would be a problem. However, he’d managed. He’d made do with less. Finally, he got his jeans and boxers down, before his free hand moved to work her jeans down. All the while, they were kissing whatever they could of each other. He definitely wasn’t about to stop kissing her. 

After a few moments of struggle, he finally got an access point. He shoved himself deep inside her, both their moans filling the room. Luckily, the kids were away, so they could be as loud as they wanted. It was a good thing too, because he planned on splitting her in half that night. 

- - - 

“Fucy yes,” Lily moaned against his lips, biting hard at his lower lip. Oh, she loved this. She loved it when they could truly let loose. She leaned back against the wall, not afraid of letting him know exactly how he was making her feel. It would always feel beautiful with him. He had been her first. He had been her every time. He was her always. It was a little sexier when she was pregnant, knowing what he’d done to her. 

There was something rather animalistic about it, for lack of a better word. 

She giggled as he let her down, turning her around and fucking her against the bathroom counter; so that they could both watch exactly what was going on. She stared at him, moaning as he spoke all the dirty things to her about them watching themselves. She gasped as his hand moved down beween her legs, pleasuring her as he pounded her. There was absolutely nowhere that she’d ever rather be than somewhere being fucked mercilessly by her husband. It was fucking incredible. She turned her head, moaning as he kissed her hard, the way that it felt was like nothing else. This man. This man.

//

Tiredly, Lily moved to unlock the door to her parents house, walking inside and clicking the door closed behind her. Slowly, she walked through into the ktichen, smiling as she laid her gaze on her Mom. “Morning,” she spoke softly, walking over and pressing a kiss to her cheek. 

“Did you two have a good night?” She flashed her a knowing smile, which obviously made her blush.

“Yes, we did.”

Her Mom then immediately looked her over, narrowing her eyes slightly, “Is something different about you? Have you had your hair done? No, it’s not that.”

Slowly, she shook her head, smirking a tad. “Nope, nothing different about me at all.” She glanced over at the kids, who were both snuggled up on the couch along with their cousin Dudley, watching a movie. They loved being at their Grandma and Grandpa’s house. They were doted upon. They’d spent a little chunk of their very early lives living there. It had been hellish moving out. She’d been homesick, her parents had missed them all desperately. It had been hard. She’d been young, and hadn’t been able to do the whole moving out for college thing. Her move out had been for good. She wouldn’t have had it any other way though.

“Are you pregnant?”

She side-eyed her Mom, “Why would you think that?”

“You are, aren’t you?”

“Mom, sssh!” Luckily, the kids were far too engrossed in their movie to have overheard any of that. Hesitantly, she nodded; not really wanting to have told anyone just yet, but coud make an exception for her own Mom. 

“Oh, darling. I knew it. I knew it. You have that same bewildered look you had the first time around. Your skin, too. You are lucky to have...”

“Pregnancy acne?” She rolled her eyes, “Nope. Not lucky.”

She smirked, “Anyway, we’re going to wait until the twelve week scan. You know me, Mom. I’m not taking any chances.” She rested her hand over her tummy, so excited. It was her turn again, finally. “Although, we did go out on the bike last night...” She smirked as her Mom tutted disapprovingly, shaking her head. “Why did you buy him that damned thing?”

“Because he works so hard and... he gave that up, that one little part of his life that he’d loved, for us. He needed that back. He’s a grown man now, Mom. He’s sensible.” She laughed, “Anyway, you’ll keep quiet about this, hmm?” She smiled, “Thanky you for having them, as always. I’ve now got to dry and drag them away.” She sighed, given that it was a difficult task every time. 

//

She picked up the next folder in her in-tray, clicking the corresrponding appointment on her calander.

Seriously? She double-checked the record and appointment details, her eyes wide. 

Slowly, she moved to stand up, picking up the chart and attaching the folder, before walking out into the waiting room, “Cissa?” She smiled, before holding open the door for her.

“I hadn’t realised that you’d be... going public,” she laughed, not quite able to help herself, as the blonde walked over. “Come in, please.” She then gestured over to her examination table. 

Oh, fuck. Fuck. 

She wasn’t going to be pregnant at the same time as Narcissa with their undoubtedly precious and long-awaited first-born? She’d told her many times that they hadn’t wanted to get pregnant too young, that they’d wanted to wait, that the moment had to be perfect. 

Oh, to be overshadowed would be an understatement. 

She set down the chart, exhaling a deep breath before walking over. “Let me get you started with this, please,” she handed her over an empty sample cup. “And then we can take it from there!”

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 :)
