By the end of this read, you’ll gain insights into why migrating to Angular 17 is beneficial and the exciting features you can leverage.
Angular 17 Unveiled
Released on November 6, 2023, Angular 17 marks a significant milestone in frontend development. Building upon the foundation laid by Angular 16, this release introduces several noteworthy features that promise to elevate the developer experience.
Declarative Control Flow Syntax
One of the standout features of Angular 17 is the introduction of a declarative control flow syntax. This empowers developers with a more efficient and expressive template syntax. This enhancement simplifies the creation and management of complex conditional logic.
Deferrable Views
Angular 17 introduces deferrable views, enabling the loading and rendering of views only when necessary.This enhancement leads to better performance and more efficient use of resources.
Angular Team’s Continuous Efforts
The updates in Angular 17 are a testament to the Angular team’s commitment to continuous improvement. Addressing challenges and feedback from the Angular community, each release aims to empower developers. To leverage these advancements fully, consider utilizing AngularJS development services.

Exploring Angular 17 Features and Updates
New Syntax for Control Flow in Templates
Angular 17 introduces a new declarative control flow syntax based on the @- syntax. This syntax, similar to other programming languages like JavaScript and Python, enhances the readability of complex conditional codes.
Example:
<div @if="isLoggedIn">
Great! You are logged in successfully.
</div>Automatic Migration to Built-in Control Flow
Facilitating a seamless transition, Angular 17 provides a schematic in the @angular/core package for automatically migrating code to the new control flow syntax:
ng g @angular/core:control-flowBuild Performance with ESBuild
Angular 17 defaults to using ESBuild for new Angular projects, significantly enhancing build performance. Existing projects can migrate to ESBuild by updating the angular.json file.

Enhanced Support for Server Side Rendering (SSR)
Angular 17 strengthens its support for server-side rendering (SSR), with the introduction of a –ssr switch for new projects. Additionally, the @angular/ssr package can be added to enable SSR later.
Deferred Loading
Angular’s “Defer” feature introduces a new template syntax that allows developers to specify when certain elements or components should load. This goes beyond traditional lazy loading methods, offering more advanced control over component loading.
Example:
<div @defer="condition">
When the condition is true, your content will be loaded lazily.
</div>
Other Features of Angular 17
- Angular 17 extends support for custom element bindings and element providers.
- Improved support for internationalization and accessibility.
- Router now supports the View Transitions API.
- Lazy loading of animations.
- Enhanced diagnostic warnings for template signal-getter calls.
- Changes to data-bound signals result in marking only directly affected components as dirty, improving performance.
How to Install Angular 17
Installing Angular 17 is straightforward using npm (Node Package Manager). Enter the command below in your Command Line Interface (CLI):
npm install --global @angular/cli@nextThis instruction ensures the installation of the most recent Angular CLI version on your system.
