Connect Hyperdrive to a Supabase Postgres database.

Atualizado em Ver como Markdown

This example shows you how to connect Hyperdrive to a Supabase ↗ Postgres database.

1. Allow Hyperdrive access

You can connect Hyperdrive to any existing Supabase database as the Postgres user which is set up during project creation. Alternatively, to create a new user for Hyperdrive, run these commands in the SQL Editor ↗.

CREATE ROLE hyperdrive_user LOGIN PASSWORD 'sufficientlyRandomPassword';

-- Here, you are granting it the postgres role. In practice, you want to create a role with lesser privileges.
GRANT postgres to hyperdrive_user;

The database endpoint can be found in the database settings page ↗.

With a database user, password, database endpoint (hostname and port) and database name (default: postgres), you can now set up Hyperdrive.

2. Create a database configuration

To configure Hyperdrive, you will need:

  • The IP address (or hostname) and port of your database.
  • The database username (for example, hyperdrive-demo) you configured in a previous step.
  • The password associated with that username.
  • The name of the database you want Hyperdrive to connect to. For example, postgres.

Hyperdrive accepts the combination of these parameters in the common connection string format used by database drivers:

postgres://USERNAME:PASSWORD@HOSTNAME_OR_IP_ADDRESS:PORT/database_name

Most database providers will provide a connection string you can directly copy-and-paste directly into Hyperdrive.

To create a Hyperdrive configuration with the Cloudflare dashboard:

  1. In the Cloudflare dashboard, go to the Hyperdrive page.

    Go to Hyperdrive ↗

  2. Select Create Configuration.

  3. Fill out the form, including the connection string.

  4. Select Create.

To create a Hyperdrive configuration with the Wrangler CLI:

  1. Open your terminal and run the following command. Replace <NAME_OF_HYPERDRIVE_CONFIG> with a name for your Hyperdrive configuration and paste the connection string provided from your database host, or replace user, password, HOSTNAME_OR_IP_ADDRESS, port, and database_name placeholders with those specific to your database:

    npx wrangler hyperdrive create <NAME_OF_HYPERDRIVE_CONFIG> --connection-string="postgres://user:password@HOSTNAME_OR_IP_ADDRESS:PORT/database_name"

  2. This command outputs a binding for the Wrangler configuration file:

    {
	"$schema": "./node_modules/wrangler/config-schema.json",
	"name": "hyperdrive-example",
	"main": "src/index.ts",
	// Set this to today's date
	"compatibility_date": "2026-07-20",
	"compatibility_flags": [
		"nodejs_compat"
	],
	// Pasted from the output of `wrangler hyperdrive create <NAME_OF_HYPERDRIVE_CONFIG> --connection-string=[...]` above.
	"hyperdrive": [
		{
			"binding": "HYPERDRIVE",
			"id": "<ID OF THE CREATED HYPERDRIVE CONFIGURATION>"
		}
	]
}
    "$schema" = "./node_modules/wrangler/config-schema.json"
name = "hyperdrive-example"
main = "src/index.ts"
# Set this to today's date
compatibility_date = "2026-07-20"
compatibility_flags = [ "nodejs_compat" ]

[[hyperdrive]]
binding = "HYPERDRIVE"
id = "<ID OF THE CREATED HYPERDRIVE CONFIGURATION>"

3. Use Hyperdrive from your Worker

Install the node-postgres driver:


								
									
									npm
									 i pg@>8.16.3

If using TypeScript, install the types package:


								
									
									npm
									 i -D @types/pg

Add the required Node.js compatibility flags and Hyperdrive binding to your wrangler.jsonc file:

{
	// required for database drivers to function
	"compatibility_flags": [
		"nodejs_compat"
	],
	// Set this to today's date
	"compatibility_date": "2026-07-20",
	"hyperdrive": [
		{
			"binding": "HYPERDRIVE",
			"id": "<your-hyperdrive-id-here>"
		}
	]
}
compatibility_flags = [ "nodejs_compat" ]
# Set this to today's date
compatibility_date = "2026-07-20"

[[hyperdrive]]
binding = "HYPERDRIVE"
id = "<your-hyperdrive-id-here>"

Create a new Client instance and pass the Hyperdrive connectionString:

// filepath: src/index.ts
import { Client } from "pg";

export default {
	async fetch(
		request: Request,
		env: Env,
		ctx: ExecutionContext,
	): Promise<Response> {
		// Create a new client instance for each request. Hyperdrive maintains the
		// underlying database connection pool, so creating a new client is fast.
		const client = new Client({
			connectionString: env.HYPERDRIVE.connectionString,
		});

		try {
			// Connect to the database
			await client.connect();

			// Perform a simple query
			const result = await client.query("SELECT * FROM pg_tables");

			return Response.json({
				success: true,
				result: result.rows,
			});
		} catch (error: any) {
			console.error("Database error:", error.message);

			return new Response("Internal error occurred", { status: 500 });
		}
	},
};
