Autosave draft

React chapter 77 · debounce + optimistic status · source: common pattern · save without a button

The problem

Save is a button. The user walks away and loses the paragraph. Or you POST on every keystroke and melt the API. There is no "saved 2s ago" signal.

The pattern that fixes it

Local state is the optimistic draft (instant). Debounce a save (600–1500ms). Ignore stale responses (68). Status: idle → saving → saved | error. Pair with localStorage (72) if the network is optional.
