SSR Hydration: Don't Re-render, Reuse
Source: angular.devadvanced
Hydration tells your client-side app to reuse the HTML sent by the server instead of wastefully re-rendering it. This prevents UI flicker in Server-Side Rendered apps and improves load performance.
Think of hydration as waking up a pre-built app on the client. Instead of rebuilding the DOM, it reuses the HTML sent by the server, attaching state and interactivity. This is essential for SSR apps to prevent UI flicker and improve Core Web Vitals. The main footgun is that hydration breaks if you manipulate the DOM directly, forcing you to refactor your code or explicitly use `ngSkipHydration`.
