error-tracking-nextjs

PostHog error tracking captures unhandled runtime exceptions across both client-side and server-side Next.js environments, providing visibility into performance issues and user-impacting failures without requiring heavy refactoring of your existing error handling logic.

PostHog provides dedicated guidance and instrumentation for both frontend and backend error tracking in Next.js, including server-side monitoring, client-side error capture, source maps, and external integrations for comprehensive cross-context visibility.

Your Next.js PostHog setup requires environment variables for error monitoring to ensure config-driven security, allowing minimal code changes to existing error handling while safely managing API keys across server and client environments.

Yes, you can add PostHog error tracking without disrupting existing Next.js error handling, as the integration is designed to be non-disruptive and requires only minimal code changes to start capturing runtime errors automatically.

The best way to monitor server-side runtime errors in Next.js with PostHog is to follow the provided server-side instrumentation guidance, which enables automatic capture of backend exceptions and performance issues directly within your existing application architecture.
