The process where browser JavaScript attaches interactivity to server-rendered HTML.
Hydration makes a page clickable after the server sends the first markup. Mismatches happen when the server and client render different text or structure.
Plainly
Think of Hydration as a named building block in a big LEGO app. The process where browser JavaScript attaches interactivity to server-rendered HTML.
In practice
Use it when you are mapping how the app is structured or explaining a feature to a teammate or agent. In practice, define the owner, input, output, and failure mode before you rely on it.
