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:

basic-integration-1.0-begin.md - PostHog Setup - Begin ← Start here
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

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

Never use useEffect() for analytics capture - it's brittle and causes errors
Prefer event handlers or routing mechanisms to trigger analytics calls
Add handlers where user actions occur rather than reacting to state changes
Remember that source code is available in the node_modules directory
Check package.json for type checking or build scripts to validate changes
posthog-js is the JavaScript SDK package name

Identifying users

Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.

Error tracking

Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.
