Next.js+Vercel Postgres
Stack IntegrationNext.js + Vercel Postgres Integration Guide
Vercel Postgres is a serverless PostgreSQL offering built for Next.js deployments — zero configuration, edge-compatible queries, and automatic connection pooling.
Use Cases
- Serverless database queries from Next.js Server Components and Route Handlers
- Edge-compatible SQL queries in Next.js Middleware
- Pooled connections handling Next.js serverless function cold starts
- Preview deployments with isolated Vercel Postgres branches
Implementation
Install `@vercel/postgres` and use the `sql` tagged template literal for parameterized queries — it handles connection pooling automatically. In Server Components, query directly without an explicit connection setup. For migrations, use a migration tool like `node-postgres` with a custom migration script or integrate Prisma targeting the Vercel Postgres connection string. Never use the direct (non-pooled) connection string from serverless functions — always use the pooled endpoint.
