honojs/hono v4.4.0

on GitHub

Hono v4.4.0 is now available! Let's take a look at the new features.

Support JSR

Now, Hono is available on JSR - a new JavaScript/TypeScript registry! You can install the Hono package from JSR right now. If you want to run your Hono app on Deno, you can install it with the following command:

deno add @hono/hono

Then, use it in your code!

// main.ts
import { Hono } from '@hono/hono'

const app = new Hono()

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

export default app

And run it:

deno serve main.ts

If you edit the deno.json and set the paths appropriately, the exact same code that you are familiar with will work in Deno, Cloudflare Workers, and Bun.

deno.json:

{
  "imports": {
    "hono": "jsr:@hono/hono@^4.4.0"
  }
}

JSR is not exclusive to Deno. You can use it with npm and Bun.

# npm
npx jsr add @hono/hono

# bun
bunx jsr add @hono/hono

And, removing "slow types" has improved the performance of TypeScript type inference.

With the introduction of JSR, the previous package publishing from deno.land/x will be obsolete.

Introduce ConnInfo Helper

The ConnInfo Helper is a helper helps you to get the connection information. For example, you can get the client's remote address easily.

import { Hono } from 'hono'
import { getConnInfo } from 'hono/deno' // For Deno

const app = new Hono()

app.get('/', (c) => {
  const info = getConnInfo(c) // info is `ConnInfo`
  return c.text(`Your remote address is ${info.remote.address}`)
})

export default app

Thank you for creating the feature, @nakasyou!

Introduce Timeout Middleware

The Timeout Middleware is a middleware enables you to easily manage request timeouts in your application.

Here is a simple example:

import { Hono } from 'hono'
import { timeout } from 'hono/timeout'

const app = new Hono()

// Applying a 5-second timeout
app.use('/api', timeout(5000))

// Handling a route
app.get('/api/data', async (c) => {
  // Your route handler logic
  return c.json({ data: 'Your data here' })
})

Thank you for creating the feature, @watany-dev!

Improving JSDoc

We are now trying to improve the JSDocs. In the PR, we've added the JSDocs for all middleware. Thank you, @goisaki!
