--- title: Connect Astro to Postgres on Neon subtitle: Learn how to make server-side queries to Postgres from .astro files or API routes. enableTableOfContents: true updatedOn: '2025-07-29T16:22:53.110Z' --- Astro builds fast content sites, powerful web applications, dynamic server APIs, and everything in-between. This guide describes how to create a Neon Postgres database and access it from an Astro site or application. To create a Neon project and access it from an Astro site or application: ## Create a Neon project If you do not have one already, create a Neon project. Save your connection details including your password. They are required when defining connection settings. 1. Navigate to the [Projects](https://console.neon.tech/app/projects) page in the Neon Console. 2. Click **New Project**. 3. Specify your project settings and click **Create Project**. ## Create an Astro project and add dependencies 1. Create an Astro project if you do not have one. For instructions, see [Getting Started](https://docs.astro.build/en/getting-started/), in the Astro documentation. 2. Add project dependencies using one of the following commands: ```shell npm install pg ``` ```shell npm install postgres ``` ```shell npm install @neondatabase/serverless ``` ## Store your Neon credentials Add a `.env` file to your project directory and add your Neon connection string to it. You can find the connection string for your database by clicking the **Connect** button on your **Project Dashboard** to open the **Connect to your database** modal. For more information, see [Connect from any application](/docs/connect/connect-from-any-app). ```shell shouldWrap DATABASE_URL="postgresql://:@.neon.tech:/?sslmode=require&channel_binding=require" ``` ## Configure the Postgres client There a multiple ways to make server side requests with Astro. See below for two of those options: **astro files** and **Server Endpoints (API Routes)**. ### astro files In your `.astro` files, use the following code snippet to connect to your Neon database: ```astro --- import { Pool } from 'pg'; const pool = new Pool({ connectionString: import.meta.env.DATABASE_URL, ssl: true }); const client = await pool.connect(); let data = null; try { const response = await client.query('SELECT version()'); data = response.rows[0].version; } finally { client.release(); } --- {data} ``` ```astro --- import postgres from 'postgres'; const sql = postgres(import.meta.env.DATABASE_URL, { ssl: 'require' }); const response = await sql`SELECT version()`; const data = response[0].version; --- {data} ``` ```astro --- import { neon } from '@neondatabase/serverless'; const sql = neon(import.meta.env.DATABASE_URL); const response = await sql`SELECT version()`; const data = response[0].version; --- {data} ``` #### Run the app When you run `npm run dev` you can expect to see the following when you visit [localhost:4321](localhost:4321): ```shell shouldWrap PostgreSQL 16.0 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit ``` ### Server Endpoints (API Routes) In your server endpoints (API Routes) in Astro application, use the following code snippet to connect to your Neon database: ```javascript // File: src/pages/api/index.ts import { Pool } from 'pg'; const pool = new Pool({ connectionString: import.meta.env.DATABASE_URL, ssl: true, }); export async function GET() { const client = await pool.connect(); let data = {}; try { const { rows } = await client.query('SELECT version()'); data = rows[0]; } finally { client.release(); } return new Response(JSON.stringify(data), { headers: { 'Content-Type': 'application/json' } }); } ``` ```javascript // File: src/pages/api/index.ts import postgres from 'postgres'; export async function GET() { const sql = postgres(import.meta.env.DATABASE_URL, { ssl: 'require' }); const response = await sql`SELECT version()`; return new Response(JSON.stringify(response[0]), { headers: { 'Content-Type': 'application/json' }, }); } ``` ```javascript // File: src/pages/api/index.ts import { neon } from '@neondatabase/serverless'; export async function GET() { const sql = neon(import.meta.env.DATABASE_URL); const response = await sql`SELECT version()`; return new Response(JSON.stringify(response[0]), { headers: { 'Content-Type': 'application/json' }, }); } ``` #### Run the app When you run `npm run dev` you can expect to see the following when you visit the [localhost:4321/api](localhost:4321/api) route: ```shell shouldWrap { version: 'PostgreSQL 16.0 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit' } ``` ## Source code You can find the source code for the applications described in this guide on GitHub.
