PR Evaluation Report

Summary

This PR adds PostHog analytics integration to a React Router 7 e-commerce application (shopper). It implements client-side SDK initialization, error tracking via ErrorBoundary, and comprehensive e-commerce event tracking covering the full shopping funnel (product views, cart operations, checkout, and purchase). The integration uses proper SSR configuration and environment variables.

Files changed	Lines added	Lines removed
11 (app code)	+171	-1

Confidence score: 3/5 🤔

• Invalid PostHog init option: The defaults: '2026-01-30' option in entry.client.tsx is not a valid PostHog init option and should be removed or replaced with a valid configuration option like persistence or feature flag defaults. [MEDIUM]
• Missing reverse proxy: No reverse proxy configured to circumvent adblockers - events may be blocked by browser extensions in production. [MEDIUM]
• Noisy search tracking: product_searched fires on every keystroke which will create excessive events; should be debounced. [MEDIUM]
• Missing user identification: No posthog.identify() calls implemented despite the app having user email in checkout form. [LOW]

File changes

Filename	Score	Description
app/entry.client.tsx	3/5	New file - PostHog SDK initialization with PostHogProvider wrapper. Uses env vars but has invalid defaults option.
app/root.tsx	4/5	Adds error tracking via captureException in ErrorBoundary. Clean implementation.
app/routes/cart.tsx	4/5	Tracks cart operations (remove, quantity update, checkout start) with rich properties.
app/routes/checkout.tsx	4/5	Tracks order_placed event with order details.
app/routes/products..tsx	4/5	Tracks product_viewed in useEffect and product_added_to_cart. Proper dependency array.
app/routes/products.tsx	3/5	Tracks add-to-cart, search, and category filter. Search tracking fires on every keystroke.
package.json	5/5	Adds posthog-js and @posthog/react dependencies.
vite.config.ts	5/5	Adds SSR noExternal config for PostHog packages.
react-router.config.ts	4/5	Enables v8_middleware future flag (not strictly required but harmless).
package-lock.json	5/5	Lock file updates for new dependencies.
posthog-setup-report.md	4/5	Documentation of implementation with helpful dashboard suggestions.

App sanity check: 4/5 ✅

Criteria	Result	Description
App builds and runs	Yes	Build completes successfully with no errors
Preserves existing env vars & configs	Yes	Adds new VITE_PUBLIC_POSTHOG_KEY and VITE_PUBLIC_POSTHOG_HOST env vars; existing config untouched
No syntax or type errors	Yes	TypeScript compilation passes, no errors
Correct imports/exports	Yes	All imports from @posthog/react and posthog-js are correct
Minimal, focused changes	Yes	Changes are focused on PostHog integration across relevant e-commerce routes

Issues

• Invalid init option: defaults: '2026-01-30' in entry.client.tsx is not a valid PostHog init configuration option. This should be removed or replaced with valid options. [MEDIUM]

Other completed criteria

• Existing app code, CartContext, Navbar, and routing structure preserved
• SSR configuration properly handles PostHog packages via noExternal
• Environment variables follow Vite's VITE_PUBLIC_ prefix convention
• No hardcoded API keys or secrets
• Clear, readable code following existing patterns
• Appropriate use of optional chaining (posthog?.capture)

PostHog implementation: 3/5 ⚠️

Criteria	Result	Description
PostHog SDKs installed	Yes	posthog-js ^1.345.5 and @posthog/react ^1.7.1 added to dependencies
PostHog client initialized	Yes	Initialized in entry.client.tsx with PostHogProvider wrapping HydratedRouter
capture()	Yes	Multiple capture calls for e-commerce events across routes
identify()	No	No posthog.identify() calls despite having user email in checkout form
Error tracking	Yes	captureException() in ErrorBoundary captures React errors
Reverse proxy	No	No reverse proxy configured - direct PostHog API host used

Issues

• No reverse proxy: Events are sent directly to VITE_PUBLIC_POSTHOG_HOST without a reverse proxy. Ad blockers will likely block these requests in production, causing data loss. [MEDIUM]
• Missing user identification: The checkout form collects email but never calls posthog.identify() to associate events with the user. [LOW]
• Invalid init option: defaults: '2026-01-30' is not a valid PostHog configuration option. [MEDIUM]

Other completed criteria

• API key loaded from environment variable (not hardcoded)
• API host configurable via environment variable
• SSR compatibility configured with noExternal in vite.config.ts
• Optional chaining used to handle null posthog instance safely
• PostHogProvider wraps app at client entry point
• __add_tracing_headers configured for tracing

PostHog insights and events: 4/5 ✅

Filename	PostHog events	Description
app/routes/products..tsx	product_viewed, product_added_to_cart	Captures product detail views (funnel top) and add-to-cart with full product metadata
app/routes/products.tsx	product_added_to_cart, product_searched, category_filtered	Captures product list add-to-cart, search queries, and category filter selections
app/routes/cart.tsx	product_removed_from_cart, cart_quantity_updated, checkout_started	Captures cart modifications and checkout initiation with cart contents
app/routes/checkout.tsx	order_placed	Captures successful order completion with order total and items
app/root.tsx	captureException	Captures application errors for debugging

Issues

• Noisy search tracking: product_searched fires on every keystroke in the search input. This should be debounced (e.g., 300ms delay) to avoid excessive event volume and provide cleaner analytics. [MEDIUM]
• Missing pageview tracking: Automatic pageview capture not explicitly enabled. React Router navigation won't trigger pageviews without capture_pageview: true in init config. [LOW]

Other completed criteria

• Full e-commerce funnel tracked: product_viewed → product_added_to_cart → checkout_started → order_placed
• Events include rich properties (product_id, product_name, product_price, product_category, quantity)
• Cart events include quantity changes and cart totals
• Order events include order total and full item list
• Category and search filtering tracked for user behavior analysis
• Events enable building conversion funnels and cart abandonment analysis
