Angular 17 Components DOM API and When to use DOM APIs in Components?

Angular handles most DOM creation, updates, and removals for you. However, you might rarely need to directly interact with a component's DOM.

When to use DOM APIs?

While Angular handles most rendering concerns, some behaviors may still require using DOM APIs. Some common use cases include:

1.     Managing element focus

2.     Measuring element geometry, such as with getBoundingClientRect

3.     Reading an element's text content

4.     Setting up native observers such as  MutationObserver, ResizeObserver, and others as well.

5.     Avoid inserting, removing, and modifying DOM elements. In particular, never directly set an element's innerHTML property, which can make your application vulnerable to cross-site scripting (XSS) exploits.

This is the YouTube video link for this: - https://youtu.be/Au8gjL2zZPc


Try to following:-

Avoid direct DOM manipulation whenever possible.

Render callbacks never run during server-side rendering or build-time pre-rendering.

Never directly manipulate the DOM inside of other Angular lifecycle hooks.
