@hono/node-server

Hono on Node.js

This is HTTP Server for Hono on Node.js. Hono is ultrafast web framework for Cloudflare Workers, Deno, and Bun. It's not for Node.js. BUT, there may be a case that you really want to run on Node.js. This library is an adapter server that connects Hono and Node.js.

Hono is ultra fast, but not so fast on Node.js, because there is an overhead to adapt Hono's API to Node.js.

By the way, it is 2.x times faster than Express.

Install

You can install from npm registry with npm command:

npm install @hono/node-server

Or use yarn:

yarn add @hono/node-server

Usage

Just import @hono/node-server at the top and write the code as usual. The same code that runs on Cloudflare Workers, Deno, and Bun will work.

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

const app = new Hono()
app.get('/', (c) => c.text('Hono meets Node.js'))

serve(app, (info) => {
  console.log(`Listening on http://localhost:${info.port}`) // Listening on http://localhost:3000
})

For example, run it using ts-node. Then an HTTP server will be launched. The default port is 3000.

ts-node ./index.ts

Open http://localhost:3000 with your browser.

Options

port

serve({
  fetch: app.fetch,
  port: 8787, // Port number, default is 3000
})

createServer

import { createServer } from 'node:https'
import fs from 'node:fs'

//...

serve({
  fetch: app.fetch,
  createServer: createServer,
  serverOptions: {
    key: fs.readFileSync('test/fixtures/keys/agent1-key.pem'),
    cert: fs.readFileSync('test/fixtures/keys/agent1-cert.pem'),
  },
})

Middleware

Most built-in middleware also works with Node.js. Read the documentation and use the Middleware of your liking.

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

const app = new Hono()

app.get('*', prettyJSON())
app.get('/', (c) => c.json({ 'Hono meets': 'Node.js' }))

serve(app)

Serve Static Middleware

Use Serve Static Middleware that has been created for Node.js.

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

//...

app.use('/static/*', serveStatic({ root: './' }))

Note that root must be relative to the current working directory - absolute paths are not supported.

Options

rewriteRequestPath

If you want to serve files in ./.foojs with the request path /__foo/*, you can write like the following.

app.use(
  '/__foo/*',
  serveStatic({
    root: './.foojs/',
    rewriteRequestPath: (path: string) => path.replace(/^\/__foo/, ''),
  })
)
