+description: Learn how to use PostgreSQL in your Nuxt application deployed on Cloudflare Workers / Pages and how to speed up your queries using Hyperdrive.
+---
+
+## Pre-requisites
+
+Cloudflare does not host PostgreSQL databases, you need to setup your own PostgreSQL database.
+
+::note{to="https://www.postgresql.org/support/professional_hosting/" target="_blank" icon="i-logos-postgresql"}
+See a list of professional PostgreSQL hosting providers.
+::
+
+If you prefer to use Cloudflare services, you can use Cloudflare D1 which is built on SQLite, see our [Database](/docs/features/database) section.
+
+## Setup
+
+1. Make sure to use the `@nuxthub/core` module, see the [installation section](/docs/getting-started/installation#add-to-a-nuxt-project) for instructions.
+
+```ts [nuxt.config.ts]
+export default defineNuxtConfig({
+  modules: ['@nuxthub/core',],
+});
+```
+
+::note
+The module ensures that you can connect to your PostgreSQL database using [Cloudflare TCP Sockets](https://developers.cloudflare.com/workers/runtime-apis/tcp-sockets/.)
+::
+
+2. Install the [`postgres`](https://www.npmjs.com/package/postgres) NPM package in your project.
+
+```bash
+npx nypm add postgres
+```
+
+::tip{icon="i-ph-rocket-launch"}
+That's it, you can now use the `postgres` package to connect to your PostgreSQL database.
+::
+
+::warning
+Please note that [`pg`](https://www.npmjs.com/package/pg) is not compatible at the moment.
+::
+
+## Usage
+
+We can add our PostgreSQL database connection in our `.env` file.
+
+```bash [.env]
+NUXT_POSTGRES_URL=postgresql://user:password@localhost:5432/database
+```
+
+Then, we can create a `usePostgres()` server util to connect to our database in our API route.
+
+```ts [server/utils/postgres.ts]
+import postgres from 'postgres'
+
+export function usePostgres () {
+  if (!process.env.NUXT_POSTGRES_URL) {
+    throw createError('Missing `NUXT_POSTGRES_URL` environment variable')
+  }
+
+  return postgres(process.env.NUXT_POSTGRES_URL as string, {
+    ssl: 'require'
+  })
+}
+```
+
+We can now use the `usePostgres()` function to connect to our database in our API route.
+
+```ts [server/api/db.ts]
+export default eventHandler(async (event) => {
+  const sql = usePostgres()
+
+  const products = await sql`SELECT * FROM products`
+
+  // Ensure the database connection is closed after the request is processed
+  event.waitUntil(sql.end())
+  return products
+})
+```
+
+::tip
+You may notice that we don't import `usePostgres()`. This is because Nuxt auto-imports the exported variables & functions from `server/utils/*.ts` when used.
+::
+
+## Hyperdrive
+
+[Hyperdrive](https://developers.cloudflare.com/hyperdrive/) is a Cloudflare service that accelerates queries you make to existing databases, making it faster to access your data from across the globe. By maintaining a connection pool to your database within Cloudflare’s network, Hyperdrive reduces seven round-trips to your database before you can even send a query: the TCP handshake (1x), TLS negotiation (3x), and database authentication (3x).
+
+::important{to="https://developers.cloudflare.com/hyperdrive/platform/pricing/" target="_blank"}
+Hyperdrive is only available on the Workers Paid plan ($5/month), **learn more**.
+::
+
+To use Hyperdrive in your Nuxt application:
+1. [Create a Hyperdrive configuration](https://dash.cloudflare.com/?to=/:account/workers/hyperdrive/create)
+2. Add your Hyperdrive ID in your `nuxt.config.ts` file
+
+```ts [nuxt.config.ts]
+export default defineNuxtConfig({
+  modules: ['@nuxthub/core'],
+  hub: {
+    bindings: {
+      hyperdrive: {
+        // <BINDING_NAME>: <HYPERDRIVE_ID>
+        POSTGRES: 'your-hyperdrive-id'
+      }
+    }
+  }
+})
+```
+
+3. Update our `usePostgres()` function to use the `POSTGRES` binding when available.
+
+```ts [server/utils/postgres.ts]
+import type { Hyperdrive } from '@cloudflare/workers-types'
+import postgres from 'postgres'
+
+export function usePostgres() {
+  const hyperdrive = process.env.POSTGRES as Hyperdrive | undefined
+  const dbUrl = hyperdrive?.connectionString || process.env.NUXT_POSTGRES_URL
+  if (!dbUrl) {
+    throw createError('Missing `POSTGRES` hyperdrive binding or `NUXT_POSTGRES_URL` env variable')
+  }
+
+  return postgres(dbUrl, {
+    ssl: !hyperdrive ? 'require' : undefined
+  })
+}
+```
+
+::warning
+Hyperdrive is currently not available in development mode at the moment. We are working on a solution to make it work in development mode and remote storage with an upcoming `hubHyperdrive()`.
+::
+
+4. [Deploy your application](/docs/getting-started/deploy) with the NuxtHub CLI or Admin to make sure the Hyperdrive bindings are set.
+
+::tip{icon="i-ph-rocket-launch"}
+You can now access your PostgreSQL database from anywhere in the world at maximum speed.

+If you are not comfortable with Cloudflare D1 database (SQLite), you can now use your own PostgreSQL database.
+
+We wrote a recipe on [How to use a PostgreSQL database](/docs/recipes/postgres) with NuxtHub.
+
+This recipe explains how to connect to your PostgreSQL database and how to leverage Hyperdrive bindings in your Nuxt application to accelerate your database responses.
+
+::callout
+Right now, hyperdrive bindings are not available in development mode, we are working with the Cloudflare team to make them available in development mode as well with remote storage.
