PR Evaluation Report

Summary

This PR integrates PostHog analytics into a React Router v7 "CloutHub" fake influencer social network app. The integration includes SDK initialization in the client entry point, PostHogProvider wrapping the app, error tracking in the ErrorBoundary, and custom event tracking across multiple components for user actions like navigation clicks, post likes, follower purchases, and user follows.

Files changed	Lines added	Lines removed
17	+549	-139

Confidence score: 3/5 🤔

• Missing posthog.identify() implementation: No user identification is set up, which limits the ability to track users across sessions and correlate events to specific users. [MEDIUM]
• No reverse proxy configuration: Events are sent directly to PostHog, making them susceptible to ad blockers. [MEDIUM]
• Error boundary hook usage concern: Using usePostHog() hook directly in ErrorBoundary component may cause issues - hooks should not be called in error boundaries as they can fail during error states. [MEDIUM]

File changes

Filename	Score	Description
app/entry.client.tsx	4/5	New file correctly initializes PostHog with environment variables, sets up PostHogProvider, and configures tracing headers. Uses modern defaults: '2025-11-30' config.
app/root.tsx	3/5	Adds error tracking with captureException(), but using usePostHog() hook inside ErrorBoundary is risky - hooks may fail during error states.
app/components/PostCard.tsx	5/5	Clean implementation of post_liked and post_unliked events with relevant properties (post_id, username, verified status).
app/components/header.tsx	5/5	Well-implemented navigation tracking with navigation_clicked events including nav_item and destination properties.
app/routes/buy-followers.tsx	5/5	Excellent funnel tracking with follower_package_selected and follower_package_purchased events with comprehensive properties (price, amounts, price_per_follower).
app/routes/home.tsx	5/5	CTA click tracking implemented cleanly with cta_clicked events.
app/routes/profile.tsx	4/5	user_followed event tracking added with username and verified status. Minor: event only fires on follow, not unfollow.
app/components/StatCard.tsx	5/5	Formatting changes only (no functional changes).
app/hooks/use-hydrated.ts	5/5	Formatting changes only (semicolons to none).
app/lib/data/fake-data.ts	5/5	Minor formatting and quote style changes.
app/lib/utils/localStorage.ts	5/5	Whitespace formatting changes only.
app/routes/analytics.tsx	5/5	Formatting changes only.
app/routes/feed.tsx	5/5	Formatting changes only.
package.json	5/5	Correctly adds posthog-js and @posthog/react dependencies.
pnpm-lock.yaml	5/5	Lock file properly updated with PostHog dependencies and transitive deps.
vite.config.ts	5/5	Correctly adds posthog-js and @posthog/react to ssr.noExternal for dev builds.
posthog-setup-report.md	5/5	Comprehensive setup report documenting events, env vars, and next steps.

App sanity check: 4/5 ✅

Criteria	Result	Description
App builds and runs	Yes	Dependencies properly added, SSR config updated, no breaking changes
Preserves existing env vars & configs	Yes	Only adds new PostHog env vars, existing configs preserved
No syntax or type errors	Yes	All TypeScript code is valid, proper typing throughout
Correct imports/exports	Yes	All imports from @posthog/react and posthog-js are correct
Minimal, focused changes	Yes	Changes are focused on PostHog integration with minor formatting

Issues

• ErrorBoundary hook usage: Using usePostHog() inside ErrorBoundary component is risky. React hooks may not work reliably during error states. Consider importing posthog directly from posthog-js and calling posthog.captureException() instead. [MEDIUM]

Other completed criteria

• Environment variables documented in posthog-setup-report.md
• Build configuration properly updated in vite.config.ts
• Code is readable and follows existing patterns
• No unnecessary modifications to non-PostHog related functionality

PostHog implementation: 3/5 ⚠️

Criteria	Result	Description
PostHog SDKs installed	Yes	posthog-js@^1.333.0 and @posthog/react@^1.7.0 added to package.json
PostHog client initialized	Yes	Initialized in entry.client.tsx with PostHogProvider wrapping the app, using env vars for API key and host
capture()	Yes	Multiple events captured: navigation_clicked, cta_clicked, post_liked, post_unliked, follower_package_selected, follower_package_purchased, user_followed
identify()	No	No posthog.identify() calls - users are not identified
Error tracking	Yes	captureException() called in ErrorBoundary (with caveats about hook usage)
Reverse proxy	No	No reverse proxy configured - events sent directly to PostHog

Issues

• Missing user identification: No posthog.identify() implementation. The app has user context (fakeUser) that could be used to identify users, enabling cross-session tracking and user-level analytics. [MEDIUM]
• No reverse proxy: Events sent directly to us.i.posthog.com will be blocked by ad blockers. Consider setting up a reverse proxy through the app's server. [MEDIUM]
• Pageview tracking unclear: While PostHog's default config may auto-capture pageviews, this is not explicitly configured or verified for React Router v7's client-side navigation. [LOW]

Other completed criteria

• API key loaded via environment variable (not hardcoded)
• Correct API host configuration
• PostHogProvider properly wraps the application
• Tracing headers configured for localhost and window.location.host
• No PII in event properties
• SSR compatibility handled in vite.config.ts

PostHog insights and events: 4/5 ✅

Filename	PostHog events	Description
app/entry.client.tsx	SDK initialization	Sets up pageview tracking (via defaults) and session replay
app/root.tsx	captureException	Captures errors in ErrorBoundary for error monitoring
app/components/header.tsx	navigation_clicked	Tracks header navigation with nav_item and destination properties
app/routes/home.tsx	cta_clicked	Tracks CTA button clicks with cta_name and destination
app/components/PostCard.tsx	post_liked, post_unliked	Tracks engagement with post_id, username, verified status
app/routes/buy-followers.tsx	follower_package_selected, follower_package_purchased	Full funnel tracking with package details, price, price_per_follower
app/routes/profile.tsx	user_followed	Tracks follow actions with username and verified status

Issues

• Missing unfollow tracking: Only user_followed is tracked, not unfollow actions - creates asymmetric data for engagement analysis. [LOW]
• No page-specific analytics events: Analytics page (analytics.tsx) has no PostHog events tracking dashboard interactions. [LOW]

Other completed criteria

• Events represent real user actions and product flows
• Purchase funnel is well-instrumented for conversion analysis
• Events include relevant properties for segmentation
• Events are appropriately named with consistent conventions
• Properties enable building meaningful insights (price analysis, user verification status, etc.)
