Root Cause

An unhandled error in a React component crashes the entire app because no Error Boundary is present, or the Error Boundary's fallback prop is misconfigured.

Workarounds

  1. 92% success Create a class component Error Boundary with getDerivedStateFromError and componentDidCatch 
    class ErrorBoundary extends React.Component { state = { hasError: false }; static getDerivedStateFromError(error) { return { hasError: true }; } componentDidCatch(error, info) { logError(error, info); } render() { return this.state.hasError ? <Fallback /> : this.props.children; } }

  2. 93% success Use react-error-boundary library for declarative error boundaries with reset capability 
    import { ErrorBoundary } from 'react-error-boundary'; <ErrorBoundary fallbackRender={({ error, resetErrorBoundary }) => <div><p>{error.message}</p><button onClick={resetErrorBoundary}>Retry</button></div>}><App /></ErrorBoundary>

Dead Ends

Common approaches that don't work:

  1. Use try-catch inside the render function to catch errors 80% fail

    try-catch only works for imperative code; it cannot catch errors thrown during React's rendering phase or in child components

  2. Wrap the entire app in a single Error Boundary at the root 50% fail

    A single top-level boundary catches everything but replaces the entire UI with fallback; user loses all context and cannot interact with unaffected parts of the app
