SSR State Hydration: Syncing Server and Client State
SSR hydration syncs server and client state to prevent UI errors. The server renders the page with initial data, then sends that data to the client to "hydrate" its own state store. The footgun is using a global store on the server, which leaks data.
SSR state hydration prevents UI mismatches by ensuring your client app starts with the same state the server used to render the page. The server fetches data, pre-renders the HTML, and sends the initial state along for the client to "hydrate" its own store. This is critical for frameworks like Next.js using Redux. The main footgun is creating a global store on the server; this leaks data between user requests, so always create a new store instance for each request.
