v4.1.0

Hono v4.1.0 is now available! Let's take a look at the new features.

WebSocket Helper

Now Hono supports WebSockets! With WebSocket helper, you can easily handle WebSockets in your application. Currently, Cloudflare Workers / Pages, Deno, and Bun adapters are available.

const app = new Hono()

app.get(
  '/ws',
  upgradeWebSocket((c) => {
    return {
      onMessage(event, ws) {
        console.log(`Message from client: ${event.data}`)
        ws.send('Hello from server!')
      },
      onClose: () => {
        console.log('Connection closed')
      }
    }
  })
)

PRC mode is now also supported for WebSockets endpoints. The following is a demo.

Thanks @nakasyou!

Body Limit Middleware

Introducing Body Limit Middleware. This middleware can limit the file size of the request body.

const app = new Hono()

app.post(
  '/upload',
  bodyLimit({
    maxSize: 50 * 1024, // 50kb
    onError: (c) => {
      return c.text('overflow :(', 413)
    }
  }),
  async (c) => {
    const body = await c.req.parseBody()
    if (body['file'] instanceof File) {
      console.log(`Got file sized: ${body['file'].size}`)
    }
    return c.text('pass :)')
  }
)

Thanks @EdamAme-x and @usualoma!

ES2022

We made the target in the tsconfig.json as ES2022 instead of ES2020. So, the generated JavaScript files are now ES2022. That made the file size smaller! The following is the result of the minify and build of "Hello World" with Wrangler.

// ES2020
hono => Total Upload: 20.15 KiB / gzip: 7.42 KiB
hono/tiny => Total Upload: 12.74 KiB / gzip: 4.69 KiB

// ES2022
hono => Total Upload: 18.46 KiB / gzip: 7.09 KiB
hono/tiny => Total Upload: 11.12 KiB / gzip: 4.38 KiB

Performance has also been improved in some Node.js environments.
