Does Neon Work With Netlify?
Neon and Netlify work together seamlessly for building full-stack applications with serverless functions and PostgreSQL.
Quick Facts
How Neon Works With Netlify
Neon and Netlify integrate naturally because Neon exposes a standard PostgreSQL connection string that Netlify Functions and Edge Functions can consume via environment variables. Your Netlify Functions (Node.js/TypeScript based) can query Neon databases using any PostgreSQL client library like `pg`, `prisma`, or `drizzle`. Connection pooling is essential here—Neon's built-in connection pooler ensures you don't exhaust database connections across multiple concurrent function invocations, which is critical for serverless architectures. The developer experience is straightforward: create a Neon database, copy the connection string, add it to Netlify's environment variables, and query it from your functions. Neon's branching feature pairs well with Netlify's deploy previews—you can create preview databases for each branch deployment. The architecture is stateless and scales automatically on both sides, making this an excellent choice for rapid iteration on full-stack projects without managing infrastructure.
Best Use Cases
Quick Setup
npm install pg dotenv// netlify/functions/api.ts
import { Pool } from 'pg';
const pool = new Pool({
connectionString: process.env.DATABASE_URL,
});
export default async (req: Request) => {
try {
const result = await pool.query(
'SELECT id, name FROM users LIMIT 10'
);
return new Response(
JSON.stringify(result.rows),
{ status: 200, headers: { 'Content-Type': 'application/json' } }
);
} catch (error) {
return new Response(
JSON.stringify({ error: 'Database query failed' }),
{ status: 500 }
);
}
};
// netlify.toml
[env]
DATABASE_URL = "postgresql://user:password@ep-xxx.neon.tech/dbname?sslmode=require"Known Issues & Gotchas
Cold starts on Netlify Functions combined with database connection overhead
Fix: Use Neon's connection pooler (pgbouncer) in transaction mode, implement connection reuse across function invocations, or consider persistent functions for high-frequency queries
Default Neon free tier has limited compute hours; Netlify free tier has function execution limits
Fix: Monitor usage in both dashboards early, upgrade tiers as needed, use caching strategies to reduce database queries
Network latency between Netlify Functions (global edge) and Neon (single region default)
Fix: Ensure your Neon compute is in the same region as your primary Netlify functions, or accept minor latency for edge functions
Connection string contains credentials in plain text as environment variable
Fix: Use Netlify's secrets management, never commit .env files, rotate credentials regularly
Alternatives
- •Supabase + Netlify: Similar PostgreSQL experience with built-in auth and real-time features
- •Vercel PostgreSQL + Vercel: Tighter integration if using Vercel instead of Netlify
- •PlanetScale (MySQL) + Netlify: MySQL alternative with similar serverless benefits
