# PostHog integration for Next.js App Router This skill helps you add PostHog analytics to Next.js App Router applications. ## Workflow Follow these steps in order to complete the integration: 1. `basic-integration-1.0-begin.md` - PostHog Setup - Begin ← **Start here** 2. `basic-integration-1.1-edit.md` - PostHog Setup - Edit 3. `basic-integration-1.2-revise.md` - PostHog Setup - Revise 4. `basic-integration-1.3-conclude.md` - PostHog Setup - Conclusion ## Reference files - `EXAMPLE.md` - Next.js App Router example project code - `next-js.md` - Next.js - docs - `identify-users.md` - Identify users - docs - `basic-integration-1.0-begin.md` - PostHog setup - begin - `basic-integration-1.1-edit.md` - PostHog setup - edit - `basic-integration-1.2-revise.md` - PostHog setup - revise - `basic-integration-1.3-conclude.md` - PostHog setup - conclusion The example project shows the target implementation pattern. Consult the documentation for API details. ## Key principles - **Environment variables**: Always use environment variables for PostHog keys. Never hardcode them. - **Minimal changes**: Add PostHog code alongside existing integrations. Don't replace or restructure existing code. - **Match the example**: Your implementation should follow the example project's patterns as closely as possible. ## Framework guidelines - For Next.js 15.3+, initialize PostHog in instrumentation-client.ts for the simplest setup - For feature flags, use useFeatureFlagEnabled() or useFeatureF...
