Building fast, scalable apps without dealing with complex setups is a big win for small teams, and MVP projects. I am excited to share Cloudflare Workers, a serverless platform that offers a free tier perfectly suited for small and medium projects, and showcase how to deploy Hono, to build fast & globally distributed applications. Unlike the container-based AWS ECS solution previously recommended by COE team, Cloudflare Workers provides a simpler, more cost-effective alternative for modern application development.

What is Cloudflare Workers?

Cloudflare Workers is a serverless platform that lets you run JavaScript or TypeScript code on Cloudflare’s network, covering over 300 locations worldwide. It uses edge computing, so your code runs close to users, reducing delays and boosting performance. Picture it as a small, smart server that works globally, grows with demand, and doesn’t need you to manage hardware.

Why Use Cloudflare Workers for Hono?

Hono is a fast, lightweight web framework designed for Cloudflare Workers, making them a great match. Unlike the AWS ECS setup, which uses containers and needs more management, Cloudflare Workers offers an easier, serverless option perfect for small projects, MVPs, and side projects. Here’s why it’s a smart pick:

1. Free Plan for Small Projects: The free plan gives you 100,000 requests per day, plenty for MVPs, prototypes, or small apps—no cost needed.

2. Made for Hono: Hono works seamlessly with Workers, delivering strong performance.

3. Affordable Growth: Need more than the free plan? Paid options start at just $5/month, much cheaper than AWS ECS.

4. Super-Fast: Edge computing ensures quick responses for users worldwide.

5. Easy Deployment: Launching apps is simple, unlike the complex container setup of AWS ECS.

6. Auto-Scaling: Scales automatically, so you don’t worry about server size.

7. Flexible: Works for web apps, APIs, background tasks, and even AI features.

Hyperdrive: Speeding Up Your Database

For apps that need database access, Hyperdrive makes Cloudflare Workers even better by speeding up queries. It’s caching common data, finding the best routes, and retrying failed connections automatically. This means quick data access, even if users are far from your database.

How Hyperdrive Helps:

- Global Reach: Sends queries to the closest location, cutting delays.

- Smart Storage: Saves frequently used data for faster access.

- Reliable: Retries failed queries and reconnects without manual fixes.

- Works With: Cloudflare’s D1 (a simple SQLite database), standard SQL databases, and other serverless databases.

For example, if your database is in Singapore but users are in the U.S., queries might take 300ms. Hyperdrive can drop this to 5-30ms, making your MVP or small app feel fast and professional.

Wrangler: Official tool for Deployment

Cloudflare’s Wrangler is a command-line tool that makes working with Workers easy. Unlike AWS ECS, which requires setting up container images and services, Wrangler keeps things simple by helping you:
- Test code on your computer before launching.- Deploy apps with one command.- Manage settings like environment variables, static files, or database connections.- Connect to databases (like Hyperdrive or D1) and other Cloudflare tools.

Getting Started with Wrangler:

Install Wrangler by running:

npm install -g wrangler

Example Wrangler Configuration

To use Hyperdrive, environment variables, and static assets, you need to configure your wrangler.toml file. Here’s an example that sets up a Hono app with these features:

name = "hono-app"
main = "src/index.ts"
compatibility_date = "2025-05-29"

# Environment variables
[vars]
API_KEY = "your-secret-key
"ENVIRONMENT = "production"

# Hyperdrive binding
[[hyperdrive]]binding = "HYPERDRIVE"
id = "your-hyperdrive-id"
localConnectionString = "mysql://YOUR-DB-USER:YOUR-PASSWD@0.0.0.0:3306/hono_db"

# Static assets
assets = { directory = "public" }

- Hyperdrive: Connects to a MySQL database with the specified ID and a local connection string for testing.

- Environment Variables: Stores sensitive data like API_KEY or app settings like ENVIRONMENT.

- Static Assets: Serves files (HTML, CSS, JS, images) from the ./public folder.
This setup lets your Hono app access databases, use secure variables, and serve static files like a website’s frontend.

Launching Hono with Hyperdrive and Drizzle

Let’s walk through deploying a Hono app with Hyperdrive and show how to use Drizzle to work with the Hyperdrive connection string. This demo proves how simple it is to create a scalable, high-speed MVP without spending money or managing servers.

Step-by-Step Guide:

1. Create a Cloudflare Account: Sign up for a free Cloudflare account to use Workers and Hyperdrive.

2. Install Wrangler: Run the command above to set up Wrangler.

3. Build a Hono App:

- Start a new Hono project with Node.js.

- Add a basic API endpoint, like this:

   import { Hono } from "hono";
   const app = new Hono();
   app.get("/", (c) => c.text("Hi, It work!"));
   export default app;

4. Set Up Hyperdrive:

Create a Hyperdrive instance: Use Wrangler to create a Hyperdrive database with a connection string for your MySQL database:

# Create hyperdirve
wrangler hyperdrive create my-fast-db --connection-string="mysql://YOUR-USERNAME:YOUR-PASSWD@YOUR-DB-HOSTNAME:3336/hono_graphql

This command generates a Hyperdrive ID (e.g., 67ec87b9eb994c108225cc99696354c9) to add to your wrangler.toml file.

Create a D1 database:

npx wrangler d1 create hono-app-db

This creates a D1 database named hono-app-db and outputs a databaseid to add to your wrangler.toml file under d1databases.

5. Use Drizzle with Hyperdrive:
- Install Drizzle ORM and the MySQL driver:

npm install drizzle-orm mysql2

- Create a Drizzle setup to use the Hyperdrive connection string in your Hono app:

   import { Hono } from "hono";
   import { drizzle } from "drizzle-orm/mysql2";
   import mysql from "mysql2/promise";
   import { projects } from '../../db/schema';

   const app = new Hono();

   app.get("/projects", async (c) => {
     // Get Hyperdrive connection string from environment
     const connectionString = c.env.HYPERDRIVE.connectionString;

     const pool = mysql.createPool(connectionString);

     const db = drizzle(pool);

     const users = await db.select().from(projects).execute();

     // Close the pool
     await pool.end();

     return c.json(users);
   });

   export default app;

- The HYPERDRIVE binding in wrangler.toml makes the Hyperdrive connection string available as c.env.HYPERDRIVE.connectionString.

- Drizzle uses the mysql2 driver to connect to the database via the connection string.

- You can query your database (e.g., a projects table) and return results as JSON.

- The pool is closed after the query to free resources.

6. Deploy with Wrangler:

- Run wrangler deploy to build and launch your Hono app.

- Check that your app works globally with fast responses.

7. Check Speed: Use Hyperdrive’s smart routing and storage to confirm quick database queries.
This setup gets your Hono app live in minutes, reaching users worldwide with no server setup and no cost under the free plan—perfect for MVPs and small projects. Using Drizzle with Hyperdrive makes database queries clean and efficient.
