Ever wished your Angular app could load faster, ace SEO, and dodge UI glitches? 🚀🪄 That's where Angular Hydration swoops in! Picture it like sending your app for a spa day – 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 ngSkipHydration for components incompatible with hydration.
• Useful for components with DOM manipulation issues.

Considerations

• Internationalization (i18n): No support yet.
• Third-Party Libraries: Some may need ngSkipHydration for compatibility.

And there you have it – a quick rundown of the essential facts to consider about Angular Hydration. Have you played around with Hydration yet? 😊
