Deploying to Vercel with a Database
Connect a Vercel Postgres or Neon database to a SvelteKit app deployed on Vercel.
Deploying to Vercel with a Database is a free Sveltejs Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Sveltejs Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Choose a DB
Vercel offers Postgres, KV, and Blob storage. Neon and PlanetScale are also popular.
Create the Project
Connect your GitHub repo to Vercel; auto-detected as SvelteKit.
Set Env Vars
Add DATABASE_URL in the Vercel project dashboard under Environment Variables.
Choose Runtime
Node runtime for full Node compat; edge runtime for faster cold starts but with limitations.
Migration in CI
Run Drizzle migrations during the build or as a separate deployment step.
Connection Pooling
Use a pooler (Neon, Supabase, PgBouncer) for serverless DB access to avoid connection exhaustion.
Edge-Compatible Drivers
For edge runtime, use drivers like Neon's serverless driver that work over HTTP.
Preview Deployments
Vercel creates preview URLs per PR. Use them with a staging DB or branch.
Logs and Monitoring
Inspect runtime logs in the Vercel dashboard; integrate with Sentry for errors.
Custom Domain
Add your domain in Vercel; HTTPS is automatic.
Cost Awareness
Track function executions and DB usage; serverless can be cheap or pricey depending on traffic.
Quick Check
Why use connection pooling on serverless?
Recap
Deploy to Vercel with env vars, choose runtime and DB driver wisely, and use a connection pooler for serverless workloads.
