📝 Walkthrough

Walkthrough

This pull request removes PostHog analytics integration from the web application. PostHog imports and event capture calls are deleted across multiple components and files. The PostHog provider is removed from the root provider composition. The posthog-js dependency is removed from package.json. One component (upgrade-plan-button.tsx) gains behavioral changes around stripeId handling.

Poem

🐰 PostHog's journeys fade to quiet streams,
Analytics drift like forgotten dreams,
No more events will trace our way,
Just Plausible truths shall stay,
The rabbit hops on, lighter, free! ✨

70-80: ⚠️ Potential issue | 🔴 Critical

Fix the mismatch between client-side and server-side upgrade logic.

The condition on line 72 (!stripeId || currentPlan === "free") does not align with the server-side endpoint's decision logic. The server returns { url } when workspace.stripeId && activeSubscription exists, but the client expects { url } when stripeId && currentPlan !== "free". These conditions differ:

• If a workspace has stripeId but no active subscription (e.g., canceled), the server returns { id } but the client expects { url }, causing router.push(undefined).
• If a workspace is on the "free" plan but has an active subscription, the server returns { url } but the client expects { id }, causing stripe.redirectToCheckout({ sessionId: undefined }).

Either align the client condition to match the server's activeSubscription check, or update the server logic to check currentPlan instead.

🧹 Nitpick comments (1)

apps/web/ui/modals/link-builder/og-modal.tsx (1)

168-170: Remove unused parameters for consistency with the title completion handler.

The (_, __) parameters are leftover from the removed posthog.capture call. The title completion's onFinish on line 122 already uses the cleaner () => form.

Suggested fix

-    onFinish: (_, __) => {
+    onFinish: () => {
       mutate();
     },
