PostHog error tracking for React requires initializing the SDK with environment-based API host and token configuration, wrapping your application in PostHogProvider, and enabling exception autocapture to collect runtime errors.

Minified stack traces in PostHog appear when source maps are not uploaded. You must upload source maps for your minified builds so that captured runtime exceptions resolve correctly and point back to your original source files.

PostHog exception autocapture captures global runtime exceptions, but errors caught by React Error Boundaries do not naturally propagate. You must use manual captureException at your error boundaries to ensure these failures are tracked.

PostHog groups captured runtime exceptions into searchable issues using fingerprinting and issue grouping mechanisms. This organization makes errors visible and actionable rather than lost or hard to debug.

Before capturing exceptions in React with PostHog, you need environment-based API host and token configuration. You then initialize the PostHog SDK and wrap your application component tree with PostHogProvider.

Yes, PostHog supports alerting for captured React exceptions. Once exception autocapture and error boundary tracking are enabled, you can configure alerts and monitoring based on the grouped issues generated from your application's runtime errors.
