PostHog analytics integration for Vue 3 applications that guides adding PostHog setup, environment-variable configuration, user identification on login and signup, and error tracking to Vue.js project files. Use when adding PostHog product analytics or error tracking to a Vue 3 app, or when identifying users in a Vue frontend that also has a backend.

# PostHog integration for Vue 3

This skill helps you add PostHog analytics to Vue 3 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

- `references/EXAMPLE.md` - Vue 3 example project code
- `references/vue-js.md` - Vue.js - docs
- `references/identify-users.md` - Identify users - docs
- `references/basic-integration-1.0-begin.md` - PostHog setup - begin
- `references/basic-integration-1.1-edit.md` - PostHog setup - edit
- `references/basic-integration-1.2-revise.md` - PostHog setup - revise
- `references/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

_No specific framework guidelines._

## 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.
