What Are The New Features of Angular 6, The JavaScript Framework – Know Them Here!

The newly launched & highest in the talk are the features of Angular 6, the just in a version of the javascript framework. While the measure of new highlights is insignificant or less, a ton has changed in the engine as far as tools are considered. The new tooling options are particularly extraordinary for adding new libraries and encouraging redesigning for your application.

So, things from being complicated to understandable have now become easy! The key version packages along with CDK & CLI check out sync.

Let us understand the new features of angular 6 one by one.

The most favorite – Angular Elements!

Angular 6

This is the only version which will completely support angular elements. Well, you can also say that this was the most awaited feature of the release. This is fundamentally intended to take leeway of web segments that are being upheld by all cutting-edge browsers. This will enable you to make an Angular part and distribute it as a Web Component, which can be utilized as a part of any HTML page.

Changing a segment to a custom component gives a simple way to making dynamic HTML in the Angular application. Having said that, creating and publishing a web component in Angular and using it on any HTML page is beyond expectation.

No more unnecessary compiling – The Bazel Compiler!

Oh Yes! We will begin having the Bazel compiler bolster. So, while compiling the code with Bazel Compiler, you will recompile whole code base, yet it incorporates just with vital code. This is a basic change with enormous effects, i.e. it enables you to dispatch AOT precompiled code to npm. Which implies that angular developers don’t need to stress over compiling a specific library in AOT. Why? As it is already done!

This additionally implies metadata.json is never again required, which makes it simpler for tools to check your codebase and many tools end up perfect with npm packages. So things are sorted providing quick compilation with less overhead. COOL, ISN’T IT?

The new in rendering engine – IVY!

A modify of the renderer, Ivy has additionally been getting a considerable measure of attention. The renderer ought to be fundamentally littler, which will take into account optimizing the size of the final app.

This is the third render engine for Angular. The second was the View Engine. After they supplanted it the first time, they saw increments in speed and declines in application measure, and no incompatibilities too. They are wanting to see an indistinguishable sort of results this time too.

NO to the unwanted – Service Worker!

Just as the service worker script can do wonder, it is difficult to remove them too. It runs in the browser & manages the caching too.

Once in a while when we are compiling the most recent variant of the angular application we may need to deactivate or remove the service worker, but there was no straight method to deactivate it. The game changer “safety-worker.js” file! It is the part of the bundle & now will allow you to easily deactivate it. YAYYY!

New supporting features – ng add & ng update!

Well well, take a bow developer!

There is less coding, more features in the application & in lesser time. With the new ng add feature support, you simply need to select the capabilities & it will automatically add the code for the same in the backend. This is WOW!

Worried about adding the new packages? No more worries!

The new ng update command will update the packages in your package.json file automatically. Not only this, with the new API’s it will also check out the bugs & update the code automatically saving a lot of your time.

We hope you found this piece of information useful. For any queries feel free to comment. We will be back with an in detail explanation on each new features soon!


React JS, Node JS and Angular JS: Which one is the best for web development?

To choose a right JavaScript framework for creating an amazing web application is the crucial decision for every business owner. Therefore, to choose one among these three – “React JS, Node JS and Angular JS” becomes the complicated decision because ultimately it will help your businesses to get the effective online presence of the particular brand.

In this article, we are going to compare all of these three most demanding JavaScript frameworks and we will also look at the advantages and disadvantages of each framework which can help you to choose best among them.

Angular JS:

During 2009, Google has launched open source framework called as Angular JS. It was developed with the aim of resolving an issue in single page application. Due to features like flexibility, Easy Testing and amazing user Interface Angular JS is popular.


  • Data synchronization can be possible easily between model, view, and controller.
  • It can easily create document object model without adding inner HTML code.
  • It gives vigorous template binding solution.
  • It has outstanding binary libraries.
  • It can be tested easily.
  • Coding becomes easy with simple routing and amazing UI design.


  • Sometimes it becomes hard to debug the scopes.
  • Third party integration becomes difficult.
  • With pages embedding interactive elements, it becomes slow.
  • Angular is big and little bit complex framework.

React JS:

It is considered as an open source JavaScript library rather than a framework. It is created with the aim of resolving the issues with the JavaScript frameworks related to efficient extemporization of large databases.  It has amazing features like SEO effectiveness, great efficiency and much more.


  • It has easy learning API which makes it easy to understand
  • Coding becomes easy because React JS allows reusing the coding.
  • It is high-performance open source library compares to other frameworks.
  • It is fully component-based architecture and you can easily import components in React JS.
  • With server-side rendering, you can create isomorphic/universal web applications.


  • JavaScript Extensions are sometimes not acceptable to web developers.
  • It has complicated view layer.
  • As we have discussed earlier, it is not a framework but just a library.

Node JS:

Node JS is not only the framework but it can be considered as a server. During the creation of complex application Node Js is preferable to use. Due to these top three reasons, you should select Node JS- Server-side proxy, node package manager, and data streaming.


  • You can use the same coding for both client and server-side coding.
  • Stream files can be stream easily and Node JS is easy to learn.
  • Due to asynchronous event-driven input-output, it can handle concurrent request.


  • You should have deep knowledge of JavaScript if you want to work with Node JS.
  • To take an advantage of multiple tasks, one CPU is not enough.
  • It is not intended for CPU task but only for web servers.

Here, we have discussed regarding main features and pros and cons of a particular framework. Now, let’s have a look at our opinion which can help you to take a decision to choose one among all three.

React JS-Node JS-Angular JS


Angular JS is fully featured framework compared to React JS but React JS is far better than Angular JS when it comes to performance because of implementation of virtual DOM. On the other side Node Js is used to create fast and scalable network applications.

Hope this article will help you to choose the best JavaScript framework and if you are thinking to outsource your project on particular framework then Concetto Labs is the best web and application development company to work with.

The all new AngularJS 4.2, is out of its egg shell and all the tech freaks are eager to crack the books of this Angular. So without dwindling time, let’s start counting all the new feathers in the crown of Angular 4.2.


With its novel entry, Angularjs 4.2 has brought in the much awaited new wave of animation which permits reusable animations, full blown router level animation, and multi-element animations. This much-endeavored API feature equips its user to animate their Angular apps in never dreamt before manner.

The all new query function as introduced in this version permits query feature in the template. Apart from this, it also supports pseudo-selectors, which lines up few other interesting possibilities.

To quote, we can now easily animate elements in NgFor:


With the given animation:


Now, whenever an element will leave, removed from races array, it will fade out and vice versa.

Stagger is the other new add-on under the umbrella of animation. With this add-on, staggering animations can be created with ease.


A reusable animation is another new add-on, which can be used to override the default parameter. Here is an example of changeOpacity animation:


When the element is being animated, Angular will add a ng-animating class to the element. Apart from this, one can trigger child animations using the animateChild function. Lastly, we can inject AnimationBuilder to program animations and trigger them on demand.



Here is great news! Now it’s possible to use strictNullChecks in all your applications. The ! postfix operator is also now available:

The code generated from AOT compiler will include non-null assertion operator, allowing you to do strict null checking in your templates!


The new Angular 4.2 has two new validators over and above the existing minLength, maxLength, email, and pattern: min and max, to help you ratify that the input is the value specified to the best of its level.

The information as on 17th June’17 states that the validators min and max have for the time being have been eradicated but will reappear in version 5.


TestBed called overrideProvider is the new method of this new version, which allows overriding a provider irrespective of its module/component. This feature is a very interesting add-on for developers who initially could only test in JiT mode. But not the testing can be done in AOT mode also.


Make use of the new feature flush instead of a tick to automatically pause the tests till all the macro task events have been cleared from the queue.


The new feature whenRenderingDone is useful to test components with animations.


  • Inclusion of validators for min and max attributes
  • Ease of passing an element refers to the bootstrap method of an ApplicationRef, to bootstrap directly
  • Improved i18n tooling
  • AOT testing foundation laid
  • New compiler flag alwaysCompileGeneratedCode is available
  • Configure options and set input variables are available within animations
  • Reusable animations using animation()
  • Query for inner elements within animations
  • Staggering multiple elements is possible
  • Enabled queried elements
  • Synthesize a full-blown animation when routes change
  • Program to build/control an animation using AnimationBuilder

Angular JS also was known as “Angular.js” or “AngularJS 1.X” marked its birth in the year 2010, to ease out the building of complex and data-heavy web apps through JavaScript. At the time of launch Angular JS could boast of having three jewels glued to its glory:

  1. Inimitable fast code production
  2. Effortless testable piece of application
  3. Backstage support of Google

But technology is another term for continuous change or innovation. Thus came the good news of Angular JS 2, which is very much distant in nature to its elder JS 1. Let’s study the differences in detail with examples to ensure ease of understanding on part of every reader.

Angular JS 2 has better mobile acclimatization and excels in its performance.

When Angular JS 1 was being conceived, mobile support friendly mechanism was not taken into consideration, however, Angular 2 was thoroughly mobile supported. The use of Hierarchical Dependency Injection system and unidirectional tree based change detection in Angular 2 is a considerable performance backer.


Angular 2 offers wide range of language options

Angular 2 has ES5, ES6, and TypeScript or Dart languages to select from as opposed to Angular 1 which has limited options under its umbrella, namely ES5, ES6, and Dart.

Implementation of web standards in Angular 2

Angular 2 provides exceptional quality performance as compared to Angular 1, because of the implementation of web standards (components).


Ease of setup

In the easy setup of Angular JS, one has to only add reference library and it is good to go. Whereas Angular 2 is dependent on other libraries and hence has complex steps to follow, before the final green signal.

Gone are the days of Angular 1.x controllers and $scope

In Angular 2, controllers are replaced with “Components”. Angular 2 uses zone.js to detect the changes.


Way to define local variables

In Angular JS 2 local variables are defined using hash (#).

Change in structural directives syntax

In Angular 2 ng-repeat is replaced with *ngFor. In AngularJS 2 version “2.0.0-beta.17 instead of “#” use “let”.

Use of camelCase syntax for built-in directives

Angular 2 uses camelCase syntax for built-in directives. For example, ng-model is now ngModel.

HTML DOM element properties and events

Angular 2 directly uses HTML DOM element properties and events, because of which several Angular 1 built in directives has lost their application. For example, ng-href, ng-src, ng-show and ng-hide of Angular 1, were replaced with href, src and hidden of Angular 2.

Data binding directive replaced

In Angular 2, ng-bind used for one-way data binding in Angular 1 has been replaced with [property].

Angular 1.x, one-way data binding

<input ng-bind=”technology.name”></input>

Angular 2, one-way data binding

<button (click)=”doSomething()”>

Two-way data binding

In Angular 2, ng-model used for two way data binding in Angular 1 has been replaced with [(ngModel)].

Angular 1, two-way data binding,

<input ng-model=”technology.name”></input>

Angular 2, two-way data binding,

<input [(ngModel)]=”technology.name”></input>

Bootstrapping Angular Application

In Angular 1, there are two ways to bootstrap:  ng-app attribute and other via code.


In Angular 2, it is only ng-app


Ways of Dependency Injection

In Angular 2, dependency injection is used through constructors

Changed way of routing

In Angular 1 $routeProvider.when() is used for routing. In Angular 2 @RouteConfig{(…}) is used for routing.  ng-view in Angular 1 is replaced as <router-outlet> in Angular 2.
