Angular 13: Top New Features and Updates

Posted on by Anurag Pattnaik

Angular 13, the latest version of the TypeScript-based web framework was released. The release has brought several essential updates that can be useful for Angular development.

1. TypeScript 4.4 support

TypeScript 4.4 support is now available in Angular 13. It means now we can use many fantastic language features. Moreover, they stopped supporting TypeScript 4.2 and 4.3 also. One breaking change in TypeScript 4.4 that is advantageous for Angular apps is that it no longer implements setters and getters to get a similar type.

The significant highlights of TypeScript 4.4 are:

  • Improved detection of type guards.
  • Default catch variables.
  • Faster incremental builds.
  • The control flow of conditions can be analyzed
  • Symbol and template string pattern index signatures.

2. Version 7.4 of RxJS

The Angular 13 update adds RxJS, a reactive extension for JavaScript, and includes all versions of RxJS up to and including version 7.

For apps created with ng new, RxJS 7.4 has become the default.

Existing RxJS v6.x apps will need to be manually updated with the npm install rxjs@7.4 command. You can always rely on RxJS 7 for new project creation. As for migrations, existing projects should keep on RxJS 6.

3. 100% Ivy and No More Support for View Engine

The legacy View Engine is no longer supported. Now that there is no View engine-specific metadata or older output formats, it eliminates the codebase complicacy and maintenance costs. Ivy is now the only view engine supported by Angular. Ivy can now compile individual components independently of one another, which significantly improves performance and accelerates development times.

By removing the View Engine, Angular can reduce its reliance on ngcc too. There is no more requirement of using ngcc (Angular compatibility compiler) for the libraries created using the latest APF version. The development team can expect quicker compilation as there is no more requirement for metadata and summary files.

4. IE 11 Support Removed

This stands out to be one of the significant Angular 13 features. Angular 13 no longer supports IE11. CSS code paths, build passes, polyfills, special JS, and other parameters that were previously required for IE 11 have now been completely dropped off.

As a result, Angular has grown faster, and it is now easier for Angular to use new browser features like CSS variables and web animations using native web APIs.

During project migration, running the ng update will automatically remove these IE-specific polyfills and reduce the bundle size.

5. Angular CLI Improvements

The Angular CLI is one of the key components of the Angular Puzzle. Angular CLI helps standardize the process of handling the complexities of the modern web development ecosystem by minimizing these complexities on a large scale.

With the release of Angular 13, this framework now includes a persistent build cache as a default feature, which saves built-in results to disk. As a result, the development process will be accelerated. Furthermore, you have complete control over enabling or disabling this feature in current Angular apps.

6. Improvements to Angular testing

The Angular team has made some notable changes to TestBed, which now correctly tears down test environments and modules after each test.

As the DOM now experiences cleaning after tests, developers can anticipate more optimized, less interdependent, less memory-intensive, and quicker tests.

7. Changes to the Angular Package Format (APF)

The Angular Package Format (APF) defines the format and structure of Angular Framework packages and View Engine metadata. It’s an excellent strategy for packaging every third-party library in the web development environment.

Older output formats, including some View Engine-specific metadata, are removed with Angular 13. The updated version of APF will no longer necessitate the use of ngcc. As a result of these library changes, developers can expect faster execution.

8. TestBed updates

The latest Angular update improves the TestBed significantly, as the DOM is cleaned after every test.  In addition to this, the TestBed tears down test modules and environments in a more effective manner.

Therefore, developers using Angular 13 will get faster, less interdependent, memory-intensive, and optimized tests.

9. Creating dynamic components

One Ivy-enabled API update in Angular 13 is a more streamlined method for dynamically constructing a component. ViewContainerRef.create component no longer requires an instantiated factory to construct a component (no longer need to use ComponentFactoryResolver).

Due to the improved ViewContainerRef.createComponent API, it is now possible to create dynamic components with less boilerplate code. Following is an example of creating dynamic components using previous versions of Angular.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef,
private componentFactoryResolver:
ComponentFactoryResolver) {}
createMyComponent() {
const componentFactory = this.componentFactoryResolver.
resolveComponentFactory(MyComponent);
this.viewContainerRef.createComponent(componentFactory);
}
}
[/code]

In Angular 13, this code can become as follows.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef) {}
createMyComponent() {
this.viewContainerRef.createComponent(MyComponent);
}
}
[/code]

10. NodeJS Support

Node versions older than v12.20.0 are no longer supported by the Angular framework. Web developers might face certain issues while installing different packages if working with older versions.

16.14.2 is the current stable version of NodeJS. For ensuring seamless deployment of your project, it is recommended to install the latest versions of NodeJS.

Conclusion

The Angular team tries to release a new version update every six months. Now that you know the significant updates and features of the all-new Angular 13. Apart from delivering on the Ivy everywhere promise made in Angular 12 and removing the View Engine altogether, Angular 13 has many impressive features and updates. The framework has become more efficient with inline support for fonts, simplified API, components, and CLI improvements.

The release of Angular 13 enhances the web development process so that the Angular developer can create awesome apps to meet modern web development standards.  If you’re still using Angular 12, it’s time to upgrade your next project with new features.

Why Angular is So Popular in Modern Application Development

Posted on by Jay

Angular is the platform that makes it easy to develop robust web applications. It unites the declarative templates, dependency injection, the end to end tooling and integrated the top perform to resolve the development challenges of developers. Angular authorizes developers to develop applications that could live on the web and mobile respectively.

The framework, written in pure JavaScript, was intended to decouple an application’s logic from DOM manipulation, and aimed at dynamic page updates.

The historical track record tracks back to 2009 when the Miško Hevery and Adam Abrons did publish the project called <angular>. It was aimed to help both developers and designers to build web applications by simply using the HTML tag. And it was officially released in 2010 by Google engineers.

In 2010, this framework’s main benefit was, it let you turn HTML-based documents into dynamic content. It can synchronize data automatically with models and views. So, developing with Angular became easier and faster like never before.

Thereafter Google has released various versions of Angular framework with the respective time frame. Currently, we have the Angular 7 and version 8 is in the pipeline.

Let’s have look at the released versions of Angular and the Key Dates;

By presenting the high level of abstraction, Angular makes the application development process simple for developers. However this framework does handle DOM, AJAX glues code and puts them in a well-defined structure. It helps to hold the overall puzzle of building the client-side web application as well.

Angular is, mostly used for developing single-page applications. With the wide support of Google and ideas from its sheer community forum, this framework is being always kept up to date. So, it is incorporated with the latest development trends in the competitive market.

Now let’s find out the features and architecture of Angular (7).

Features of Angular Framework:

Every developer says “This is a powerful JavaScript-based development framework” that is used in developing Web Applications. So let’s see, what makes this framework powerful.

  • Cross-Platform Features

    • Progressive Web Apps: The developers can use this modern platform to deliver app-like experiences with zero-step installation and high-quality performance.
    • Build Native: It is easy to build native mobile apps with strategies from Ionic, Cordova, or NativeScript.
    • Desktop App: By using native OS APIs, the developers can create Desktop-Installed apps for Windows, Mac, and Linux.

  • Speed & Performance

    • Code Generation: Angular helps to turn the templates into code that’s highly optimized with today’s JavaScript virtual machines.
    • Universal: Angular framework provides the first view of your application on Node.js®, .NET, PHP for near-instant rendering in just HTML and CSS. It also covers the way for sites that could optimize for SEO.
    • Code Splitting: The Angular apps load faster with the new Component Router, which brings instant code-splitting.

  • Productivity

    • Templates: The Angular framework creates UI views with easy and powerful template syntax.
    • Angular CLI: Know as a command-line tool. This tool starts building fast, add components and tests, and then instantly deploy.
    • IDEs: Angular also helps to get intellectual code completion, instant errors, and some other feedback in editors and IDEs.

  • Full Development Support

    • Animation: By using intuitive API the developers can create high-performance animation timelines with very little code of Angular.
    • Accessibility: Angular framework helps to create accessible applications with ARIA-enabled mechanism and developer guides.

The Architecture of Angular:

The framework follows popular MVC architecture.

The architecture of AngularThe Architecture of Angular

  • The Controller stands for the layer that has the business logic. User events activate the functions which are stored inside your controller. Whereas the user events are an element of the controller.
  • Views are used to symbolize the arrangement layer which is made available to the end-users.
  • And the models are used to represent your data. The data in your model can be as simple as just having past development declarations.

These were the technical perspective of the Angular framework. Now let’s see, what are the benefits of using this framework on web app development?

Well, Angular has many advantages and benefits itself. Here are like;

  • Security:

Security is always a topmost concern when it comes to the point of enterprise development or transformation of the new leading technology framework. In the Angular framework, it is more focused on data security all related data distribution of the business.

  • Declarative User Interface:

Defining the app’s user interface, Angular is the more declarative, intuitive, and fewer complex language.  For App UI, angular uses HTML. So, the developer could spend less time on program flows.

  • Integration:

In the Angular framework, it is easy to integrate third-party features like Telerik’s Kendo UI, Ionic, Famo.us, Wijmo, etc. These are pre-built into this framework. However, this is one of the most important factors to influence Angular development.

  • Less Coding:

While carrying out DOM management, a lot of JavaScript code needed to be written to design the application. But through Angular, you just can manipulate all these stuff with a lesser amount of codes.

So, the coders spend less time in the coding process as an Angular framework requires less coding.

Let’s go through a quick look where it asks for fewer codes:

  • The data model is simple and the coder doesn’t need to call the getter or setter functions.
  • The date binding feature helps developers to stop giving data manually into the view.
  • “HTML for view” feature makes it more specific.
  • The feature like Filter allows developers to manipulate the data on the view level without changing its controller.
  • The framework has a built-in dependency injection subsystem which is useful for developers developing applications in an easier way.

App Development Benefits with Angular Framework

When you have a big project in your mind, you need to think about so many perspectives like scalability, durability, less loading time, security and eye-catching as well.

On a big project, scalability is the bigger concern for its representation. By making use of MVC structure developers can increase the scalability of the project.

As I have mentioned earlier, Angular has the ability to analyze DOM and it can bind the element attributes, JavaScript, and jQuery to use in inner HTML. In a result, the web applications load faster comparing to jQuery or any other frameworks.
