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.

Framework guidelines

• posthog-react-native is the React Native SDK package name
• Use react-native-config to load POSTHOG_PROJECT_TOKEN and POSTHOG_HOST from .env (variables are embedded at build time, not runtime)
• react-native-svg is a required peer dependency of posthog-react-native (used by the surveys feature) and must be installed alongside it
• Place PostHogProvider INSIDE NavigationContainer for React Navigation v7 compatibility
