[Skip to content](#%5Ftop) # Hyperdrive Turn your existing regional database into a globally distributed database. Available on Free and Paid plans Hyperdrive is a service that accelerates queries you make to existing databases, making it faster to access your data from across the globe from [Cloudflare Workers](https://developers.cloudflare.com/workers/), irrespective of your users' location. Hyperdrive supports any Postgres or MySQL database, including those hosted on AWS, Google Cloud, Azure, Neon and PlanetScale. Hyperdrive also supports Postgres-compatible databases like CockroachDB and Timescale. You do not need to write new code or replace your favorite tools: Hyperdrive works with your existing code and tools you use. Use Hyperdrive's connection string from your Cloudflare Workers application with your existing Postgres drivers and object-relational mapping (ORM) libraries: * [ PostgreSQL ](#tab-panel-6325) * [ MySQL ](#tab-panel-6326) * [ index.ts ](#tab-panel-6321) * [ wrangler.jsonc ](#tab-panel-6322) TypeScript ``` import { Client } from "pg"; export default { async fetch(request, env, ctx): Promise { // 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(); // Sample SQL query const result = await client.query("SELECT * FROM pg_tables"); return Response.json(result.rows); } catch (e) { return Response.json({ error: e instanceof Error ? e.message : e }, { status: 500 }); } }, } satisfies ExportedHandler<{ HYPERDRIVE: Hyperdrive }>; ``` ``` { "$schema": "node_modules/wrangler/config-schema.json", "name": "WORKER-NAME", "main": "src/index.ts", "compatibility_date": "2025-02-04", "compatibility_flags": [ "nodejs_compat" ], "observability": { "enabled": true }, "hyperdrive": [ { "binding": "HYPERDRIVE", "id": "", "localConnectionString": "" } ] } ``` * [ index.ts ](#tab-panel-6323) * [ wrangler.jsonc ](#tab-panel-6324) TypeScript ``` import { createConnection } from 'mysql2/promise'; export default { async fetch(request, env, ctx): Promise { // Create a new connection on each request.
