Root Cause

React error #418 corresponds to 'Cannot update a component while rendering a different component'. This occurs when a state update is triggered in one component while another component is still rendering, violating React's rendering invariant.

中文

Workarounds

  1. 90% success Move the state update that occurs during render to a `useEffect` hook: `useEffect(() => { setState(...); }, []);` to ensure it runs after the render phase is complete.
    Move the state update that occurs during render to a `useEffect` hook: `useEffect(() => { setState(...); }, []);` to ensure it runs after the render phase is complete.
  2. 85% success If the update is triggered by a child component, use a callback pattern (e.g., pass an `onUpdate` prop) instead of calling setState directly in the child's render.
    If the update is triggered by a child component, use a callback pattern (e.g., pass an `onUpdate` prop) instead of calling setState directly in the child's render.
  3. 80% success Use `React.startTransition` to mark the state update as non-urgent, allowing React to defer it: `startTransition(() => { setState(...); });`

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Logging does not change the rendering behavior and may even exacerbate the issue by causing re-renders.

  2. 90% fail

    These do not address the root cause of cross-component state updates during render.
