Database Provider Options for Your App
When adding a database to your application, especially one deployed on Vercel, there are several excellent options to consider. Let's explore the best choices and how to implement them.
Recommended Database Providers
Vercel has first-party integrations with several database providers that work well with serverless functions 1:
- Vercel Postgres - Vercel's managed Postgres service
- Neon - Serverless Postgres with branching capabilities
- PlanetScale - MySQL-compatible serverless database
- Supabase - Postgres database with additional features like auth and storage
- Upstash - Redis database optimized for serverless
Connection Challenges with Serverless
Traditional relational databases were built for long-running compute instances, not the ephemeral nature of serverless functions. When using databases with serverless functions, you need to be aware of connection management 1.
Serverless functions are stateless and asynchronous, which can lead to connection issues:
- Each function invocation might open a new connection
- This can quickly exhaust available database connections
- Connection pooling works differently in serverless environments
Adding a Database Integration
The easiest way to add a database to your Vercel project is through native integrations 2:
- From the Vercel dashboard, go to the Integrations tab and select Browse Marketplace
- Under Native Integrations, select a database provider
- Click Install and follow the setup process
- Select a pricing plan and region for your database
- Once installed, you can connect your project to the database
