Angular 13 Features: New Features and Updates Angularite Need to Know

Introduction

The latest Angular version, 13, is officially released on November 4th, 2021. Angular is Google’s popular TypeScript-based web framework that has officially released version 13 with some attractive features for the Angular developers that will make the web applications more robust and secure.

This recent release has now come up with several essential updates that can be useful for Angular development. Without taking too much time, let’s focus on some of the Angular 13 features.

New Angular 13 Features That You Must Checkout

It’s high time to explore new Angular 13  features that have been introduced by authorized Angular development team, making it easy for the Angular developers to design and build applications.

angular 13 features

1. Introducing TypeScript 4.4

Angular 13 is now supported with TypeScript 4.4. It means that the versions before 4.4.2 are no longer supported. Some of the remarkable features of TypeScript 4.4 are as follows:

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

Once you upgrade to the Angular version 13, the package.json file will be something like this:

package-json

2. 100% Ivy

In Angular 13, you’ll not find any extensive support for View Engine. In simple words, the recent version is now 100% Ivy as there is no View Engine-specific metadata or older output formats.

With its active implementation of Ivy, it becomes easy for the developers as it eliminates the codebase complicacy and maintenance costs. Ivy assembles every component individually, which accelerates development times.

As the new version is equipped with the libraries that are specifically adopted using the latest Angular Package Format (APF), the Angular developers will no longer require ngcc for compiling. It means that there is no need for any metadata and summary files to be included, making it easy and faster to compile.

3. No Longer Support for IE11

Angular has removed the Internet Explorer 11 support to make it easy for the Angular web developers to use native web APIs and modern browser features like web animations and CSS variables.

The Angular developers will find an improved user experience and faster application loading with this update. Moreover, the developers can easily deal with smaller bundle sizes and faster app loading.

As there is no support for IE 11, the developers can easily enjoy the benefits of native web APIs and modern browser features like CSS variables and web animations. This cleavage change will undoubtedly affect authorities or institutions that still use IE 11 and have not yet switched to Microsoft Edge or other modern browsers.

4. Angular Package Format v13

The Angular Package Format (APF) is a blueprint of the structure and format of npm packages. It is also the endorsed way of packaging any third-party library in the ecosystem.

Angular13 has come up with a new APF version, and some of the significant changes in it are:

  • Ivy “partial” compilation output is generated.
  • ES2020 output is produced (ESM2020, FESM2020).
  • Older output formats like View Engine-specific metadata, are completely deprecated.
  • UMD bundles are no longer built.
  • Use the package exports with the subpath patterns feature from Node.js to expose the available outputs per entry point conditionally.

The good part of this APF is that ngcc is no longer needed. So the Angular developers can expect faster code execution as a result of library changes.

5. Component API Updates

Ivy simplifies API and makes it easy for the developers to create components dynamically. 

Before the changes in Angular v13, dynamically creating components required a lot of boilerplate code.

Inside the new API of Angular v13, you do not need ComponentFactoryResolver being injected into the constructor. Ivy creates the opportunity to instantiate the component with ViewContainerRef.createComponent without building an associated factory.

Here’s an example of creating components with previous versions of Angular:

Previous Version Angular13
@Directive({ … })

export class MyDirective {

    constructor(private viewContainerRef: ViewContainerRef,

                private componentFactoryResolver: 

                        ComponentFactoryResolver) {}

    createMyComponent() {

        const componentFactory = this.componentFactoryResolver.

                             resolveComponentFactory(MyComponent);

    

        this.viewContainerRef.createComponent(componentFactory);

    }

}

@Directive({ … })

export class MyDirective {

    constructor(private viewContainerRef: ViewContainerRef) {}

    createMyComponent() {

        this.viewContainerRef.createComponent(MyComponent);

    }

}

Note:  The code is taken from Github.

6. Form Changes

A new type called FormControlStatus has been added in Angular 13.

It is the fusion of all feasible status strings for form controls. Most of the applications are expected to consume this change without any error.

Still, if you find any technical issues with this FormControlStatus, then there might be two possibilities:

  • You might be comparing AbstractControl.status with a string; or
  • The app is using statusChanges events as if they were something other than strings.

Also, AbstractControl.status has been constricted from string to FormControlStatus and likewise StatusChanges have been narrowed from Observable<any> to Observable<FormControlStatus>.

Most applications should consume these new types seamlessly, according to the Angular changelog.

7. Routes

In Angular13, the router will no longer supplant the browser URL whenever new navigation cancels the ongoing navigation. Instead, it will eventually cause URL flicker and is ready to serve only to support some AngularJS hybrid applications. 

Instead, hybrid apps that rely on navigationId to the router should subscribe to NavigationCancel events and conduct the replaceState themselves to add navigationId to the router state.

Before going through this change, let’s consider one scenario.

Consider you have the following query parameters:

/path?q=hello?&other=123

The default URL serializer would drop everything after and include a question mark in query parameters. Unfortunately, this gives us a parameter {q: ‘hello’} that is wrong.

Do you know why?

URI specs repudiate everything after 2nd “?” passed in the query.

In Angular13, you’ll find a proposed fix that is solely responsible for parsing the query parameter to {q: ‘hello?’, other: ‘123’}.

This change provides for correct parsing.

For the router, missing outlet events would be added to RouterOutletContract. This will come eventually when specific components are rendered dynamically using the module federation.

8. Angular CLI Improvements

Angular 13 has even come up with impressive updates on Angular CLI. Here, you’ll find the support for the use of persistent build-cache by default.

This update in Angular CLI will typically result in up to 68% improvement in building speed and ergonomic options. 

Along with this, ESBuild is another factor that now works with terser to optimize global scripts. In addition, esbuild supports CSS sourcemaps and can optimize global CSS and optimize.

9. Angular Testing Improvements

In the recent version of Angular, the development team has made remarkable changes to TestBed, that currently functions properly to speed down test environments and modules after every test. 

With its impressive Angular 13 features, the Angular developers can now easily deal with anticipating optimized, less interdependent, less memory-intensive, and quicker tests. Moreover, this version is equipped with the new DOM elements, making it easy for the developers to work smoothly in cleaning the test in every project phase.

10. Advanced Update in Angular Material

Angular v13 has come up with an Accessibility (A11y) enhancement in Angular Material. The Angular development team has analyzed and inspected every element of MDCs (Material Design Components) with a primary aim to improve accessibility. 

Let’s say, they have introduced various examples of radio buttons and checkboxes with larger touch sizes, and other elements equipped with feature higher contrast modes.

11. Inline Support for Adobe Fonts

Angular 13 also highlights inline support for Adobe fonts to make responsive web applications. These fonts can extend an app’s functionality by accelerating the FCP (First Contentful Paint). Now this change is accessible to everybody by default. You only need to do ng update.

Other Additional Updates

  • The new Angular 13 features is TypeScript 4.4 support.
  • Node.js versions < v12.20 are no longer supported. It’s just due to Angular packages using the Node.js package exports feature with subpath patterns.
  • The rxjs (Reactive Extensions for JavaScript) v7 reactive programming library is supported. If you’re creating new apps with CLI, by default, it will be RxJS 7.4. Consider the case that you are using RxJS 6 in your existing app; you will have to run the command “npm install rxjs@7.4” manually for the latest update.
  • The developers can easily enable or disable the built-in validators like min, max, and minLength dynamically.
  • Error messaging functionality has been improved.
  • $localize is a stable API for internationalization.
  • The developers can even set custom conditions in ng_package.
  • The behavior of the SpyLocation used by the RouterTestingModule has been changed to match the behavior of browsers.
  • Service worker cache is cleared in the safety worker to ensure stale or broken contents are not served in future requests.
  • For the platform browser, the error message has been improved for a missing animation trigger.
  • Improvements to TestBed enable a better job of tearing down test modules and environments after each test. In the Angular12, TestBed configuration is now added by default to conveniently teardown test modules and environments. Even you can disable and configure it at your ease.
  • For the language service, support would be offered for autocomplete string literal union types in templates.

Final Thoughts

By looking at the new Angular 13 features, you must have set up your mind to use the latest version. We can say it is one of the most streamlined and previously planned upgrades for a broadly accepted TypeScript-based web framework.

Still, are you not upgraded to the latest Angular version 13? What are you waiting for?

Frequently Asked Questions

What is AngularJS?

AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS’s data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology.

Why AngularJS is better than Javascript?
  • avaScript is a client-side scripting language as well as a server-side scripting language for creating web applications. AngularJS is a framework written in JS to build single-page applications.
  • JavaScript is a language used to manipulate the document object model. AngularJS extend its attributes with other technologies like HTML.
  • JavaScript has a feature to validate the user input at the browser level before submitting the page. AngularJS is a good technology used as a server-side.
  • Javascript makes websites more interactive. AngularJS makes web applications simple and easy to create from the start.
What are the leading characteristics of AngularJS?

The various features of angularJS are as follows:

  1. Data Binding
  2. Architecture
  3. Directives
  4. Not Browser Specific
  5. Codeless
  6. Speed and Performance
  7. Dependency Injection
  8. Deep Linking
  9. Routing
