Xata

还没翻译译自英文(developers.cloudflare.com)本页 37 段都还没译

Xata is a PostgreSQL database platform designed to help developers operate and scale databases with enhanced productivity and performance. Xata provides features like instant copy-on-write database branches, zero-downtime schema changes, data anonymization, AI-powered performance monitoring, and BYOC.

Note

You can connect to Xata using Hyperdrive, which provides connection pooling and reduces the amount of round trips required to create a secure connection from Workers to your database.

Hyperdrive can provide lower latencies because it performs the database connection setup and connection pooling across Cloudflare's network. Hyperdrive supports native database drivers, libraries, and ORMs, and is included in all Workers plans. Learn more about Hyperdrive in How Hyperdrive Works.

Refer to the full Xata documentation.

To connect to Xata using Hyperdrive, follow these steps:

1. Allow Hyperdrive access

You can connect Hyperdrive to any existing Xata PostgreSQL database with the connection string provided by Xata.

Xata dashboard

To retrieve your connection string from the Xata dashboard:

  1. Go to the Xata dashboard.
  2. Select the database you want to connect to.
  3. Copy the PostgreSQL connection string.

Refer to the full Xata documentation.

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.

DashboardWrangler CLI

To create a Hyperdrive configuration with the Cloudflare dashboard:

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

    dash.cloudflare.com

  2. Select Create Configuration.

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

  4. Select Create.

Note

Hyperdrive will attempt to connect to your database with the provided credentials to verify they are correct before creating a configuration. If you encounter an error when attempting to connect, refer to Hyperdrive's troubleshooting documentation to debug possible causes.

3. Use Hyperdrive from your Worker

Install the node-postgres driver:

npmyarnpnpmbun

npm i pg@>8.16.3

Note

The minimum version of node-postgres required for Hyperdrive is 8.16.3.

If using TypeScript, install the types package:

npmyarnpnpmbun

npm i -D @types/pg

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

wrangler.jsoncwrangler.toml

{
	// required for database drivers to function
	"compatibility_flags": [
		"nodejs_compat"
	],
	// Set this to today's date
	"compatibility_date": "2026-11-02",
	"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 });
		}
	},
};
