junEver wished your Angular app could load faster, ace SEO, and dodge UI glitches? ππͺ That's where Angular Hydration swoops in! Picture it like sending your app for a spa day β all that server-side goodness now chilling on the client's turf, saving you from redoing DOM nodes.
What is Hydration?
- Restores server-rendered apps on the client.
- Reusing the DOM, preserving state, and transferring data from the server.
Why is it Important?
- Boosts Performance: Reusing DOM nodes speeds up loading.
- Enhances Core Web Vitals: Improves FID, LCP, and CLS.
- Improves SEO: Ensures search engines get fully rendered content.
- Prevents UI Issues: Avoids flicker and layout shift.
Enabling Hydration
- Server-Side Rendering (SSR): Requires an SSR application.
- Use
provideClientHydration: In the main app component/module. - Bootstrapping: Include in both client and server providers.
Constraints
- DOM Structure of server and client must match.
- No Direct DOM Manipulation to keep things smooth.
- Mismatches in DOM structure can cause errors.
Handling Errors
- Use
ngSkipHydration: Temporarily bypass issues caused by DOM differences or direct manipulation. - Skipping Hydration for Components
Skipping Hydration for Components
- Use
ngSkipHydrationfor components incompatible with hydration. - Useful for components with DOM manipulation issues.
Considerations
- Internationalization (i18n): No support yet.
- Third-Party Libraries: Some may need
ngSkipHydrationfor compatibility.
And there you have it β a quick rundown of the essential facts to consider about Angular Hydration. Have you played around with Hydration yet? π
