Key principles

  • Environment variables: Always use environment variables for PostHog keys and host URLs. Never hardcode them.
  • Minimal changes: Add error tracking alongside existing error handling. Don't replace or restructure existing error handling code.
  • Autocapture first: Enable exception autocapture in the SDK initialization before adding manual captures.
  • Source maps: Upload source maps so stack traces resolve to original source code, not minified bundles.
  • Manual capture for boundaries: Use captureException() at error boundaries and catch blocks for errors that don't propagate to the global handler.
