Hono
Hono ↗ is a small, simple, and ultrafast web framework for Cloudflare Pages and Workers, Deno, and Bun. In this guide, you will create a new Hono application and deploy it using Cloudflare Pages.
Use the create-cloudflare
↗ CLI (C3) to create a new project. C3 will create a new project directory, initiate Hono’s official setup tool, and provide the option to deploy instantly.
To use create-cloudflare
to create a new Hono project, run the following command:
npm create cloudflare@latest my-hono-app -- --framework=hono
Open your project and create a src/server.js
file (or src/server.ts
if you are using TypeScript). Add the following content to your file:
import { Hono } from "hono";const app = new Hono();
app.get("/", (ctx) => ctx.text("Hello world, this is Hono!!"));
export default app;
To serve static files like CSS, image or JavaScript files, add the following to your src/server.js/ts
file:
app.get("/public/*", async (ctx) => { return await ctx.env.ASSETS.fetch(ctx.req.raw);});
This will cause all the files in the public
folder within dist
to be served in your application.
Open your package.json
file and update the scripts
section:
"scripts": { "dev": "run-p dev:*", "dev:wrangler": "wrangler pages dev dist --live-reload", "dev:esbuild": "esbuild --bundle src/server.js --format=esm --watch --outfile=dist/_worker.js", "build": "esbuild --bundle src/server.js --format=esm --outfile=dist/_worker.js", "deploy": "wrangler pages publish dist" },
"scripts": { "dev": "run-p dev:*", "dev:wrangler": "wrangler pages dev dist --live-reload", "dev:esbuild": "esbuild --bundle src/server.ts --format=esm --watch --outfile=dist/_worker.js", "build": "esbuild --bundle src/server.ts --format=esm --outfile=dist/_worker.js", "deploy": "wrangler pages publish dist" },
Then, run the following command.
npm install npm-run-all --save-dev
Installing npm-run-all
enables you to use a single command (npm run dev
) to run npm run dev:wrangler
and npm run dev:esbuild
simultaneously in watch mode.
Start your dev workflow by running:
npm run dev
You should be able to review your generated web application at http://localhost:8788
.
All of the framework guides assume you already have a fundamental understanding of Git ↗. If you are new to Git, refer to this summarized Git handbook ↗ on how to set up Git on your local machine.
If you clone with SSH, you must generate SSH keys ↗ on each computer you use to push or pull from GitHub.
Refer to the GitHub documentation ↗ and Git documentation ↗ for more information.
Create a new GitHub repository by visiting repo.new ↗. After creating a new repository, go to your newly created project directory to prepare and push your local application to GitHub by running the following commands in your terminal:
git initgit remote add origin https://github.com/<your-gh-username>/<repository-name>git add .git commit -m "Initial commit"git branch -M maingit push -u origin main
If you use create-cloudflare
(C3) ↗ to create your new Hono project, C3 will install all dependencies needed for your project and prompt you to deploy your project via the CLI. If you deploy, your site will be live and you will be provided with a deployment URL.
- Log in to the Cloudflare dashboard ↗ and select your account.
- In Account Home, select Workers & Pages > Create application > Pages > Connect to Git.
- Select the new GitHub repository that you created and, in the Set up builds and deployments section, provide the following information:
Configuration option | Value |
---|---|
Production branch | main |
Build command | npm run build |
Build directory | dist |
After configuring your site, you can begin your first deploy. You should see Cloudflare Pages installing my-hono-app
, your project dependencies, and building your site before deploying it.
After deploying your site, you will receive a unique subdomain for your project on *.pages.dev
.
Every time you commit new code to your Hono site, Cloudflare Pages will automatically rebuild your project and deploy it. You will also get access to preview deployments on new pull requests, so you can preview how changes look to your site before deploying them to production.
For more tutorials involving Hono and Cloudflare Pages, refer to the following resources:
- Build a Staff Directory Application : In this tutorial, you will learn how to use D1 to build a staff directory. This application will allow users to access information about an organization’s employees and give admins the ability to add new employees directly within the app. To do this, you will first need to set up a D1 database to manage data seamlessly, then you will develop and deploy your application using the HonoX Framework ↗ and Cloudflare Pages.
