Overview
TheAnalyticsErrorBoundary component catches JavaScript errors in its child component tree and automatically tracks them to your analytics. It prevents your app from crashing while giving you visibility into production errors.
Props
The component tree to wrap and protect with error boundary.
Component to display when an error occurs. Defaults to a simple error message.
Custom error handler function called when an error is caught. Receives the error object and React error info including component stack.
Usage
Basic Usage
Custom Fallback UI
With Custom Error Handler
Nested Error Boundaries
Tracked Error Data
When an error is caught, the following data is automatically tracked:- Error message and stack trace
- Component stack trace
error_boundary: trueflag- Timestamp of when error occurred
- Any additional properties from your custom handler
Behavior
- Catches errors during rendering, in lifecycle methods, and in constructors
- Does NOT catch errors in event handlers (use try-catch for those)
- Does NOT catch errors in asynchronous code (setTimeout, promises)
- Does NOT catch errors during server-side rendering
- Automatically tracks error to analytics before calling custom handler
- Displays fallback UI when error occurs
- Prevents error from propagating to parent components
Best Practices
Strategic Placement
Place error boundaries at strategic points in your component tree:Graceful Degradation
Use Cases
- Prevent entire app crashes from isolated component errors
- Track production errors automatically
- Provide graceful fallback UIs
- Monitor error rates by feature or page
- Debug issues with full component stack traces
- Improve user experience during errors
