Now I have all the information needed to provide a comprehensive PR evaluation. Let me compile my findings. PR Evaluation ReportSummaryThis PR integrates PostHog analytics into a React Router v7 framework application. The implementation includes client-side SDK initialization, server-side middleware for context propagation, user identification on auth events, error tracking via error boundary, and custom event tracking across key user flows (country exploration, search/filter, and authentication).
Confidence score: 3/5 🤔
File changes
App sanity check: 4/5 ✅
Issues
|
| Criteria | Result | Description |
|---|---|---|
| PostHog SDKs installed | Yes | posthog-js: ^1.325.0, posthog-node: ^5.21.0, @posthog/react: ^1.5.2 |
| PostHog client initialized | Yes | Init in entry.client.tsx with API key and host from env vars |
| capture() | Yes | 10 custom events tracked across routes |
| identify() | Yes | Users identified on login and signup with id, username, email |
| Error tracking | Yes | captureException() in ErrorBoundary and signup catch block |
| Reverse proxy | No | Events sent directly to us.i.posthog.com - no proxy configured |
Issues
- Invalid
defaultsconfiguration:defaults: '2025-11-30'inposthog.init()is not a valid option. This appears to be a confused attempt at setting API version or defaults. [MEDIUM] - No automatic pageview tracking: Despite the setup report claiming automatic pageview tracking,
capture_pageviewis not set totrueand no route change listener is configured. React Router v7 apps need explicit pageview tracking on navigation. [MEDIUM] - No reverse proxy: Events go directly to PostHog, making them vulnerable to ad blockers. A proxy route should be configured. [MEDIUM]
- Per-request PostHog instantiation: The middleware creates a new
PostHog(posthog-node)instance for every server request. This is inefficient and should use a singleton pattern. [MEDIUM] __add_tracing_headersis internal API: Using__add_tracing_headersrelies on an internal/undocumented API that could change. [LOW]
Other completed criteria
- PostHogProvider correctly wraps the app
- Server-side middleware properly propagates session/distinct ID headers
posthog.reset()called on logout to clear user identity- Proper cleanup with
posthog.shutdown()in middleware - SSR noExternal config prevents bundling issues
- No PII in event properties (username/email in identify is appropriate)
PostHog insights and events: 4/5 ✅
| Filename | PostHog events | Description |
|---|---|---|
signup.tsx |
user_signed_up, identify(), captureException |
Tracks new user registration with user properties |
login.tsx |
user_logged_in, identify() |
Tracks login with user identification |
profile.tsx |
user_logged_out, reset() |
Tracks logout and clears user identity |
countries.tsx |
countries_searched, countries_filtered, country_claimed, country_liked, country_visited |
Comprehensive tracking of list interactions with relevant properties |
country.tsx |
country_viewed |
Tracks detail page views with country metadata |
home.tsx |
explore_clicked |
Tracks CTA engagement with location property |
root.tsx |
captureException |
Global error boundary tracking |
Issues
- Missing pageview events: No `` events captured, limiting funnel and path analysis. [MEDIUM]
- Search tracking on blur only:
countries_searchedfires on blur, missing searches where users don't blur (e.g., navigate away). Consider also tracking on navigation or form submission. [LOW]
Other completed criteria
- Events have meaningful properties (country_name, region, population, search_term, results_count)
- Events enable funnel analysis (explore_clicked → user_signed_up → country_claimed)
- Events capture real user intent and product engagement
- User identification links events to real users
- Error tracking provides exception visibility
