PostHog error tracking for Angular

This skill helps you add PostHog error tracking to Angular applications.

Reference files

references/angular.md - Angular error tracking installation - docs
references/fingerprints.md - Fingerprints - docs
references/alerts.md - Send error tracking alerts - docs
references/monitoring.md - Monitor and search issues - docs
references/assigning-issues.md - Assign issues to teammates - docs
references/upload-source-maps.md - Upload source maps - docs

Consult the documentation for API details and framework-specific patterns.

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

Use inject() instead of constructor injection. PostHog service should be injected via inject() in components/services that need it.
Create a dedicated PosthogService as a singleton root service that wraps the PostHog SDK.
Always use standalone components over NgModules.
Configure PostHog credentials in src/environments/environment.ts files, as Angular reads environment variables from these configuration files
