Now I have reviewed all the changed files. Let me generate the PR evaluation report.

PR Evaluation Report

Summary

This PR adds PostHog analytics integration to a React Router v7 "CloutHub" fake influencer social network app. The integration includes client-side PostHog initialization via entry.client.tsx, error tracking in the root error boundary, and event tracking for key user actions including follower purchases, post likes/unlikes, CTA clicks, and follow actions.

Files changed Lines added Lines removed
17 +527 -141

Confidence score: 3/5 🤔

  • Missing environment variables documentation: The .env file is mentioned in the setup report but not included in the diff. Users need VITE_PUBLIC_POSTHOG_KEY and VITE_PUBLIC_POSTHOG_HOST but these are not documented anywhere visible in the PR. [CRITICAL]
  • No automatic page view tracking: PostHog initialization doesn't enable capture_pageview explicitly, and there's no manual page view tracking on route changes. This is a significant gap for analytics. [MEDIUM]
  • No user identification: The integration lacks posthog.identify() calls anywhere in the app, limiting the ability to link events to specific users. [MEDIUM]
  • No reverse proxy configuration: Events are sent directly to PostHog without a reverse proxy, making them susceptible to ad blockers. [MEDIUM]

File changes

Filename Score Description
app/entry.client.tsx 4/5 New file with correct PostHog initialization pattern using PostHogProvider. Uses defaults: '2025-11-30' and tracing headers. Missing explicit pageview capture configuration.
app/root.tsx 3/5 Adds error tracking in ErrorBoundary using captureException. However, calling usePostHog() inside ErrorBoundary could fail if PostHogProvider is not available in SSR context.
app/components/PostCard.tsx 4/5 Adds like/unlike event tracking with good properties (post_id, username, verified status). Code is clean.
app/components/header.tsx 4/5 Adds tracking for "Buy Followers" header CTA click. Minimal, focused change.
app/routes/buy-followers.tsx 5/5 Excellent implementation of purchase funnel events (follower_package_selected, follower_package_purchased) with comprehensive properties including price, follower count, and bonus amounts.
app/routes/home.tsx 4/5 Adds CTA click tracking for main homepage buttons. Good property design with cta_name and destination.
app/routes/profile.tsx 4/5 Adds user follow tracking. Only tracks follow action, not unfollow - reasonable design choice.
app/routes/analytics.tsx 4/5 Formatting changes only, no PostHog additions. Appropriate as this page shows fake metrics.
app/routes/feed.tsx 4/5 Formatting changes only. PostHog events for feed items are handled in PostCard component.
app/components/StatCard.tsx 4/5 Formatting changes only, no functional changes.
app/hooks/use-hydrated.ts 4/5 Formatting changes only (semicolons removed). No functional changes.
app/lib/data/fake-data.ts 4/5 Minor formatting: quote style change for string with apostrophe.
app/lib/utils/localStorage.ts 4/5 Whitespace formatting changes only.
package.json 5/5 Correctly adds posthog-js and @posthog/react dependencies.
pnpm-lock.yaml 5/5 Lock file updated correctly with new dependencies.
vite.config.ts 5/5 Correctly adds PostHog packages to SSR noExternal to ensure proper transpilation.
posthog-setup-report.md 4/5 Good documentation of events and setup, though references .env file not in the diff.

App sanity check: 4/5 ✅

Criteria Result Description
App builds and runs Yes Dependencies correctly added, vite config properly updated for SSR compatibility
Preserves existing env vars & configs Yes Existing configurations preserved, PostHog additions are additive
No syntax or type errors Yes All imports/exports are correct, TypeScript types properly used
Correct imports/exports Yes @posthog/react and posthog-js imported correctly throughout
Minimal, focused changes Mostly Many formatting changes (whitespace, line breaks) alongside functional changes inflate the diff

Issues

  • Missing .env documentation: Environment variables VITE_PUBLIC_POSTHOG_KEY and VITE_PUBLIC_POSTHOG_HOST are required but not documented in the PR diff. The setup report mentions .env was created but it's not visible. [MEDIUM]
  • Excessive formatting changes: Many files have formatting-only changes (StatCard, analytics, feed, localStorage, use-hydrated) that inflate the diff and make review harder. These should ideally be separate commits. [LOW]

Other completed criteria
  • React patterns preserved correctly
  • Hook usage follows React best practices
  • Optional chaining (posthog?.capture) used appropriately for safety
  • Existing app logic and functionality unchanged
  • No PII captured in events

PostHog implementation: 3/5 ⚠️

Criteria Result Description
PostHog SDKs installed Yes posthog-js@^1.325.0 and @posthog/react@^1.5.2 added to dependencies
PostHog client initialized Yes Initialized in entry.client.tsx with PostHogProvider wrapper around the app
capture() Yes Multiple events captured: post_liked, post_unliked, user_followed, cta_clicked, buy_followers_header_clicked, follower_package_selected, follower_package_purchased
identify() No No user identification implemented anywhere
Error tracking Yes captureException(error) in root ErrorBoundary
Reverse proxy No No reverse proxy configuration; events sent directly to PostHog host

Issues

  • No identify() calls: User identification is not implemented, which limits analytics capabilities for linking events across sessions. Should call posthog.identify() when user data is available. [MEDIUM]
  • No automatic pageview tracking: PostHog init doesn't explicitly enable capture_pageview: true (though SDK defaults may handle this). Should explicitly configure or add manual tracking on route changes. [MEDIUM]
  • No reverse proxy: Events go directly to PostHog API host, making them vulnerable to ad blockers. Consider using Next.js rewrites or a custom reverse proxy. [MEDIUM]
  • ErrorBoundary hook risk: Using usePostHog() inside ErrorBoundary may fail during SSR or if provider is unavailable. Should add try-catch or null check. [LOW]

Other completed criteria
  • PostHog React provider correctly wraps the application
  • defaults: '2025-11-30' uses modern SDK configuration
  • __add_tracing_headers configured for observability
  • Optional chaining prevents crashes if PostHog unavailable
  • No PII captured in event properties
  • SSR compatibility handled via vite.config.ts noExternal

PostHog insights and events: 4/5 ✅

Filename PostHog events Description
entry.client.tsx Initialization PostHog SDK initialized with API key and host
root.tsx captureException Captures unhandled errors from ErrorBoundary for error monitoring
components/PostCard.tsx post_liked, post_unliked Tracks engagement with posts; includes post_id, username, verified status
components/header.tsx buy_followers_header_clicked Tracks clicks on header CTA - useful for conversion funnel
routes/buy-followers.tsx follower_package_selected, follower_package_purchased Full purchase funnel tracking with price, follower_count, bonus_amount, package_index
routes/home.tsx cta_clicked Tracks homepage CTA engagement with cta_name and destination properties
routes/profile.tsx user_followed Tracks follow actions with followed_username

Issues

  • No unfollow tracking: user_followed event exists but no user_unfollowed event when toggling off - asymmetric tracking. [LOW]
  • No page view tracking: Cannot analyze page-level metrics or user journeys without pageview events. [MEDIUM]
  • No session/user context: Without identify(), events cannot be attributed to users across sessions. [MEDIUM]

Other completed criteria
  • Events represent real user actions (likes, follows, purchases)
  • Purchase funnel events enable conversion analysis
  • Event properties are well-designed and contextual
  • Events can answer key product questions: "Which CTAs drive conversions?", "What's our purchase conversion rate?", "Which posts get most engagement?"
  • Error tracking captures application failures
  • No PII in captured properties
