Release Notes

Hono v4.7.0 is now available!

This release introduces one helper and two middleware.

  • Proxy Helper
  • Language Middleware
  • JWK Auth Middleware

Plus, Standard Schema Validator has been born.

Let's look at each of these.

Proxy Helper

We sometimes use the Hono application as a reverse proxy. In that case, it accesses the backend using fetch. However, it sends an unintended headers.

app.all('/proxy/:path', (c) => {
  // Send unintended header values to the origin server
  return fetch(`http://${originServer}/${c.req.param('path')}`)
})

For example, fetch may send Accept-Encoding, causing the origin server to return a compressed response. Some runtimes automatically decode it, leading to a Content-Length mismatch and potential client-side errors.

Also, you should probably remove some of the headers sent from the origin server, such as Transfer-Encoding.

Proxy Helper will send requests to the origin and handle responses properly. The above headers problem is solved simply by writing as follows.

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

app.get('/proxy/:path', (c) => {
  return proxy(`http://${originServer}/${c.req.param('path')}`)
})

You can also use it in more complex ways.

app.get('/proxy/:path', async (c) => {
  const res = await proxy(
    `http://${originServer}/${c.req.param('path')}`,
    {
      headers: {
        ...c.req.header(),
        'X-Forwarded-For': '127.0.0.1',
        'X-Forwarded-Host': c.req.header('host'),
        Authorization: undefined,
      },
    }
  )
  res.headers.delete('Set-Cookie')
  return res
})

Thanks @​usualoma!

Language Middleware

Language Middleware provides 18n functions to Hono applications. By using the languageDetector function, you can get the language that your application should support.

import { Hono } from 'hono'
import { languageDetector } from 'hono/language'

const app = new Hono()

app.use(
  languageDetector({
    supportedLanguages: ['en', 'ar', 'ja'], // Must include fallback
    fallbackLanguage: 'en', // Required
  })
)

app.get('/', (c) => {
  const lang = c.get('language')
  return c.text(`Hello! Your language is ${lang}`)
})

You can get the target language in various ways, not just by using Accept-Language.

  • Query parameters
  • Cookies
  • Accept-Language header
  • URL path

Thanks @​lord007tn!

JWK Auth Middleware

Finally, middleware that supports JWK (JSON Web Key) has landed. Using JWK Auth Middleware, you can authenticate by verifying JWK tokens. It can access keys fetched from the specified URL.

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

app.use(
  '/auth/*',
  jwk({
    jwks_uri: `https://${backendServer}/.well-known/jwks.json`,
  })
)

app.get('/auth/page', (c) => {
  return c.text('You are authorized')
})

Thanks @​Beyondo!

Standard Schema Validator

Standard Schema provides a common interface for TypeScript validator libraries. Standard Schema Validator is a validator that uses it. This means that Standard Schema Validator can handle several validators, such as Zod, Valibot, and ArkType, with the same interface.

The code below really works!

import { Hono } from 'hono'
import { sValidator } from '@​hono/standard-validator'
import { type } from 'arktype'
import * as v from 'valibot'
import { z } from 'zod'

const aSchema = type({
  agent: 'string',
})

const vSchema = v.object({
  slag: v.string(),
})

const zSchema = z.object({
  name: z.string(),
})

const app = new Hono()

app.get(
  '/:slag',
  sValidator('header', aSchema),
  sValidator('param', vSchema),
  sValidator('query', zSchema),
  (c) => {
    const headerValue = c.req.valid('header')
    const paramValue = c.req.valid('param')
    const queryValue = c.req.valid('query')
    return c.json({ headerValue, paramValue, queryValue })
  }
)

const res = await app.request('/foo?name=foo', {
  headers: {
    agent: 'foo',
  },
})

console.log(await res.json())

Thanks @​muningis!
