The @defer Directive for Angular Lazy Loading !

Angular 17 introduces a game-changing feature in the realm of lazy loading – the @defer directive. This innovation takes a step beyond traditional lazy loading methods by providing more granularity and flexibility. Let's delve into the world of @defer, understanding how it transforms user experiences and optimizes Angular applications.

Understanding Lazy Loading in Angular

Lazy loading is a fundamental technique that selectively loads resources only when users interact with a page, reducing initial loading times and enhancing overall performance.

@defer: Elevating Lazy Loading to a New Level

While previous Angular versions relied on the Router or dynamic imports for lazy loading, Angular 17 introduces @defer, offering a more sophisticated approach.

How @defer Works: Syntax Breakdown

The @defer block loads content based on specific trigger conditions. Let's explore its syntax

Example Implementation: Bringing @defer to Life

Let's look at a practical example to illustrate the implementation of @defer:

Real-world Usage Scenarios for @defer

1. Loading on User Interaction:

Trigger the loading of content only when users interact with a specific element. A seamless experience that brings content to life with a simple click!

2. Loading on Viewport Entry:

Efficiently load dynamic components as they come into view, optimizing performance and providing users with a smooth, on-demand experience.

3. Loading with a Timer (5s):

Introduce a delay of 5 seconds before displaying content, offering a controlled and timed approach to lazy loading.
