Quickstart

Get started with Hono in minutes

Get your first Hono application up and running in minutes. Hono is an ultrafast web framework built on Web Standards that works on any JavaScript runtime.

Create a New Project

The fastest way to get started is using the create-hono scaffolding tool:

1. Create your project

   Run the scaffolding command to create a new Hono project:

   npm

   npm create hono@latest
   

   yarn create hono
   

   pnpm create hono
   

   bun create hono
   

   You’ll be prompted to:

   • Enter a project name
   • Choose a template (cloudflare-workers, deno, bun, nodejs, etc.)
   • Select whether to install dependencies
2. Navigate to your project

   cd my-app
   
3. Start the development server

   The start command depends on your chosen runtime:

   Cloudflare Workers

   npm run dev
   

   bun run dev
   

   deno task start
   

   npm run dev
   
4. Open your browser

   Navigate to http://localhost:8787 (or the port shown in your terminal) to see your app running.

Your First Hono App

Here’s a simple “Hello World” example that demonstrates the core concepts:

index.ts

import { Hono } from 'hono'

const app = new Hono()

app.get('/', (c) => c.text('Hono!'))

export default app

This minimal example shows:

• Import: Bring in the Hono class from the hono package
• Create: Instantiate a new Hono application
• Route: Define a GET route at the root path
• Handler: Return a text response using the context object c
• Export: Make the app available to the runtime

Add More Routes

Expand your app with different HTTP methods and dynamic routes:

import { Hono } from 'hono'

const app = new Hono()

// Simple GET route
app.get('/', (c) => c.text('Hono!'))

// Dynamic route with parameters
app.get('/hello/:name', (c) => {
  const name = c.req.param('name')
  return c.text(`Hello, ${name}!`)
})

// POST route with JSON response
app.post('/api/users', (c) => {
  return c.json({ message: 'User created' }, 201)
})

// Wildcard route
app.get('/posts/*', (c) => {
  return c.text('Blog posts')
})

export default app

Working with Different Runtimes

One of Hono’s superpowers is that the same code runs on multiple platforms. Here’s how to run your app on different runtimes:

Cloudflare Workers

import { Hono } from 'hono'

const app = new Hono()
app.get('/', (c) => c.text('Hono!'))

export default app

Run with:

npm run dev

Bun

import { Hono } from 'hono'

const app = new Hono()
app.get('/', (c) => c.text('Hono!'))

export default app

Run with:

bun run dev

Deno

import { Hono } from 'hono'

const app = new Hono()
app.get('/', (c) => c.text('Hono!'))

Deno.serve(app.fetch)

Run with:

deno run --allow-net app.ts

Node.js

import { Hono } from 'hono'
import { serve } from '@hono/node-server'

const app = new Hono()
app.get('/', (c) => c.text('Hono!'))

serve(app)

Run with:

node app.js

For Node.js, you’ll need to install @hono/node-server separately:

npm install @hono/node-server

Response Types

Hono’s context object provides convenient methods for different response types:

import { Hono } from 'hono'

const app = new Hono()

// Text response
app.get('/text', (c) => c.text('Hello!'))

// JSON response
app.get('/json', (c) => c.json({ message: 'Hello!' }))

// HTML response
app.get('/html', (c) => c.html('<h1>Hello!</h1>'))

// Custom response
app.get('/custom', (c) => {
  return new Response('Custom', {
    status: 200,
    headers: { 'X-Custom': 'Header' }
  })
})

export default app
