PR Evaluation Report

Summary

This PR integrates PostHog analytics into a React Router v7 e-commerce "shopper" application. It adds client-side SDK initialization, server-side middleware for session correlation, error tracking in ErrorBoundary, and custom event tracking across shopping flows (products, cart, checkout).

Files changed	Lines added	Lines removed
13	+772	-5

Confidence score: 4/5 👍

• API key exposed in setup report: The posthog-setup-report.md file includes a full PostHog API key (phc_sBGFIjin7AfcLwLJ4yc79wY84KHkvrTw5SnUeKD0SWE). While PostHog client keys are public by design, including them in committed documentation is poor practice. [MEDIUM]
• No reverse proxy configured: Events are sent directly to PostHog without a reverse proxy, which means ad blockers will block analytics. [MEDIUM]
• Server middleware session correlation unused: The middleware sets up PostHog context with session/distinct IDs from headers, but no server-side events are captured to leverage this. [LOW]

File changes

Filename	Score	Description
app/entry.client.tsx	5/5	Proper PostHog client initialization with PostHogProvider, env vars, and tracing headers
app/lib/posthog-middleware.ts	4/5	Server middleware setup with session correlation, but no server events captured
app/root.tsx	4/5	Adds middleware and error tracking via captureException, though hooks in ErrorBoundary may have render issues
app/routes/cart.tsx	5/5	Comprehensive cart event tracking (remove, quantity update, checkout start) with rich properties
app/routes/checkout.tsx	5/5	Order completion tracking with full order details captured before cart clearing
app/routes/home.tsx	5/5	CTA click tracking with location context
app/routes/products..tsx	5/5	Add-to-cart tracking from product detail with quantity
app/routes/products.tsx	5/5	Search tracking (debounced), category filtering, and add-to-cart from listing
package.json	5/5	Adds posthog-js, posthog-node, and @posthog/react dependencies
react-router.config.ts	5/5	Enables v8_middleware future flag for middleware support
vite.config.ts	5/5	Correct SSR noExternal config for PostHog packages
package-lock.json	5/5	Lock file updated with new dependencies
posthog-setup-report.md	3/5	Good documentation but contains hardcoded API key

App sanity check: 4/5 ✅

Criteria	Result	Description
App builds and runs	Yes	Dependencies added correctly, SSR config updated, should build
Preserves existing env vars & configs	Yes	Original configs preserved, only additions made
No syntax or type errors	Yes	TypeScript types properly used throughout
Correct imports/exports	Yes	All imports from correct packages (@posthog/react, posthog-js, posthog-node)
Minimal, focused changes	Yes	Changes scoped to PostHog integration only

Issues

• ErrorBoundary hook usage: Using usePostHog() inside ErrorBoundary component may cause issues if PostHog context is unavailable during error states. The optional chaining (posthog?.) mitigates crashes, but exceptions may not be captured reliably. [LOW]

Other completed criteria

• Environment variables documented in setup report
• Build configuration properly updated for SSR
• Consistent code style with existing patterns
• Appropriate error handling with optional chaining

---

PostHog implementation: 4/5 ✅

Criteria	Result	Description
PostHog SDKs installed	Yes	posthog-js, posthog-node, @posthog/react in package.json
PostHog client initialized	Yes	Initialized in entry.client.tsx with PostHogProvider wrapping app
capture()	Yes	Multiple posthog?.capture() calls for user actions across 6 route files
identify()	No	No posthog.identify() calls to associate users with events
Error tracking	Yes	captureException(error) in ErrorBoundary
Reverse proxy	No	No proxy configured; events sent directly to us.i.posthog.com

Issues

• Missing user identification: No posthog.identify() calls anywhere in the codebase. User sessions won't be linked to authenticated users if the app has authentication. [MEDIUM]
• No reverse proxy for ad-blocker bypass: Events are sent directly to PostHog API host without a reverse proxy route, meaning analytics will be blocked by most ad blockers. [MEDIUM]
• Server middleware not utilized: The middleware creates a PostHog node client with session context but captures no server-side events. [LOW]

Other completed criteria

• API key loaded from environment variable (not hardcoded in code)
• Correct API host configuration
• Uses __add_tracing_headers for tracing support
• PostHogProvider properly wraps the application
• Uses defaults: '2025-11-30' for modern defaults
• Proper shutdown handling in server middleware

PostHog insights and events: 5/5 ✅

Filename	PostHog events	Description
app/routes/home.tsx	cta_clicked	Tracks hero CTA engagement with text and location properties
app/routes/products.tsx	product_searched, category_filtered, product_added_to_cart	Tracks search behavior (debounced 500ms), filter usage, and add-to-cart from listing page
app/routes/products..tsx	product_added_to_cart	Tracks add-to-cart from product detail with quantity
app/routes/cart.tsx	cart_item_removed, cart_item_quantity_updated, checkout_started	Full cart management tracking with product details and cart totals
app/routes/checkout.tsx	order_completed	Order completion with full order details (items, totals, tax)
app/root.tsx	``	Error tracking via captureException

Issues

None - event coverage is comprehensive for an e-commerce funnel.

Other completed criteria

• Events capture meaningful product properties (id, name, category, price)
• Cart events include quantity context
• Search tracking is debounced to prevent event flooding
• Order events capture full transaction details before cart clears
• Events support standard e-commerce funnel analysis (browse → cart → checkout → purchase)
• Properties are structured consistently for easy PostHog querying
