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-postgrescd bun-neon-postgresbun init -ybun add @neondatabase/serverlessCreate a .env.local file and add your Neon Postgres connection string to it.
DATABASE_URL=postgresql://username:password@ep-adj-noun-guid.us-east-1.aws.neon.tech/neondb?sslmode=require
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()`;
console.log(rows[0].version);
Start the program using bun ./index.ts. The Postgres version should be printed to the console.
bun ./index.tsPostgreSQL 16.2 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bitThis 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.
