Angular 17 Release Notes: Uncovering the Latest Updates and Features

Angular is a popular open-source web application framework developed by Google. It is based on TypeScript and provides a comprehensive set of features for building modern web applications. Angular 17 is the latest version of the framework and was released in November 2023. It includes a number of new features and improvements, making it more powerful and efficient than ever before.

Angular 17 is the latest version of the popular open-source web framework, released on November 10, 2023. It brings a number of new features and improvements, including:

Built-in control flow: Angular 17 introduces a new built-in control flow syntax, which makes it easier and more efficient to write templates. The new syntax is based on the if and for statements in JavaScript, and it can be used to render conditional content, iterate over collections, and more.

Deferrable views: Angular 17 also introduces a new feature called deferrable views. This allows you to lazy-load views, which can improve the performance of your applications. Deferrable views can be loaded based on a variety of triggers, such as user interaction, viewport visibility, and idle time.

Improved performance and build times: Angular 17 includes a number of performance and build time improvements. For example, the new built-in control flow syntax is up to 90% faster than the previous syntax. Additionally, Angular 17 builds are up to 87% faster for hybrid rendering and 67% faster for client-side rendering.

Other features and improvements: Angular 17 also includes a number of other features and improvements, such as support for TypeScript 5.2, a new experimental animation system, and router refactoring.

Here is a more detailed look at some of the key features of Angular 17:

Built-in control flow

The new built-in control flow syntax in Angular 17 is based on the if and for statements in JavaScript. This makes it easier and more efficient to write templates. For example, the following code shows how to render a conditional view using the new syntax:

HTML

<div *if="user.loggedIn">
You are logged in.
</div>

The following code shows how to iterate over a collection using the new syntax:

HTML

<ul>
<li *for="let item of items">{{ item }}</li>
</ul>

The new built-in control flow syntax is also more expressive than the previous syntax. For example, the following code shows how to use the new syntax to render a nested conditional view:

HTML

Deferrable views

Deferrable views are a new feature in Angular 17 that allow you to lazy-load views. This can improve the performance of your applications, especially on mobile devices and devices with limited network connectivity.

To create a deferrable view, you simply need to add the defer attribute to the view element. You can also specify a trigger for the deferrable view, such as user interaction, viewport visibility, or idle time.

For example, the following code shows a deferrable view that is loaded when the user clicks a button:

HTML

<button (click)="loadView()">Load view</button>

<div defer="loadView()">
This view will be loaded when the user clicks the button.
</div>

Improved performance and build times

Angular 17 includes a number of performance and build time improvements. For example, the new built-in control flow syntax is up to 90% faster than the previous syntax. Additionally, Angular 17 builds are up to 87% faster for hybrid rendering and 67% faster for client-side rendering.
