⚡ Bolt: Memoize core auth and DB queries#75
Conversation
Implement request-scoped memoization using React 'cache' for high-frequency authentication and database functions. This optimization reduces redundant JWT verifications and database roundtrips within a single request lifecycle. Key changes: - Added a conditional `memoize` helper in `lib/utils.ts` for Edge compatibility. - Memoized `verifyToken` in `lib/auth/session.ts`. - Memoized `getUser`, `getUserWithTeam`, and `getTeamForUser` in `lib/db/queries.ts`. - Added performance comments explaining the impact. Expected impact: - 100% reduction in redundant database calls for user/team data per request. - 100% reduction in redundant JWT decodes per request. - Improved Time to First Byte (TTFB) for authenticated routes.

💡 What
Implemented request-scoped memoization for core authentication and database query functions using React's
cacheutility. I also added a conditionalmemoizehelper inlib/utils.tsto ensure the application remains compatible with the Edge Runtime (used in Next.js Middleware), where React'scacheis not available.🎯 Why
In Next.js App Router, foundational functions like
getUser()are often called multiple times across different segments of a single request (e.g., inRootLayoutfor theUserProvider, in page components for authorization, and in server actions). Without memoization, each call triggers a new database query and a JWT verification, leading to unnecessary latency and resource consumption.📊 Impact
🔬 Measurement
The optimization can be verified by monitoring database query logs or adding temporary console logs to the memoized functions. You will see that for a single page load (e.g., the dashboard), these functions now execute their logic only once, even if called 3-4 times across the component tree. Type safety was verified with
pnpm exec tsc --noEmit.PR created automatically by Jules for task 5229460848385358780 started by @RAbuseedo
