Use Neon's Serverless Postgres with Bun

Neon is a fully managed serverless Postgres. Neon separates compute and storage to offer modern developer features such as autoscaling, branching, bottomless storage, and more.

Get started by creating a project directory, initializing the directory using bun init, and adding the Neon serverless driver as a project dependency.

mkdir bun-neon-postgres
cd bun-neon-postgres
bun init -y
bun add @neondatabase/serverless

Create a .env.local file and add your Neon Postgres connection string to it.


Paste the following code into your project's index.ts file.

import { neon } from "@neondatabase/serverless";

// Bun automatically loads the DATABASE_URL from .env.local
// Refer to: https://bun.sh/docs/runtime/env for more information
const sql = neon(process.env.DATABASE_URL);

const rows = await sql`SELECT version()`;


Start the program using bun ./index.ts. The Postgres version should be printed to the console.

bun ./index.ts
PostgreSQL 16.2 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit

This example used the Neon serverless driver's SQL-over-HTTP functionality. Neon's serverless driver also exposes Client and Pool constructors to enable sessions, interactive transactions, and node-postgres compatibility.

Refer to Neon's documentation for a complete overview of the serverless driver.
