Release Notes

Hono v4.9.0 is now available!

This release introduces several enhancements and utilities.

The main highlight is the new parseResponse utility that makes it easier to work with RPC client responses.

parseResponse Utility

The new parseResponse utility provides a convenient way to parse responses from Hono RPC clients (hc). It automatically handles different response formats and throws structured errors for failed requests.

import { parseResponse, DetailedError } from 'hono/client'

// result contains the parsed response body (automatically parsed based on Content-Type)
const result = await parseResponse(client.hello.$get()).catch(
  // parseResponse automatically throws an error if response is not ok
  (e: DetailedError) => {
    console.error(e)
  }
)

This makes working with RPC client responses much more straightforward and type-safe.

Thanks @​NamesMT!

Release Notes

Hono v4.8.0 is now available!

This release enhances existing features with new options and introduces powerful helpers for routing and static site generation. Additionally, we're introducing new third-party middleware packages.

  • Route Helper
  • JWT Custom Header Location
  • JSX Streaming Nonce Support
  • CORS Dynamic allowedMethods
  • JWK Allow Anonymous Access
  • Cache Status Codes Option
  • Service Worker fire() Function
  • SSG Plugin System

Plus new third-party middleware:

  • MCP Middleware
  • UA Blocker Middleware
  • Zod Validator v4 Support

Let's look at each of these.

Reduced the code size

First, this update reduces the code size! The smallest hono/tiny package has been reduced by about 800 bytes from v4.7.11, bringing it down to approximately 11 KB. When gzipped, it's only 4.5 KB. Very tiny!

Route Helper

New route helper functions provide easy access to route information and path utilities.

import { Hono } from 'hono'
import {
  matchedRoutes,
  routePath,
  baseRoutePath,
  basePath,
} from 'hono/route'

const api = new Hono()

api.get('/users/:id/posts/:postId', (c) => {
  const matched = matchedRoutes(c) // Array of matched route handlers
  const current = routePath(c) // '/api/users/:id/posts/:postId'
  const base = baseRoutePath(c) // '/api' Base route path
  const appBase = basePath(c) // '/api' Base path
  return c.json({ matched, current, base, appBase })
})

const app = new Hono()
app.route('/api', api)

export default app

These helpers make route introspection cleaner and more explicit.

Thanks @​usualoma!

JWT Custom Header Location

JWT middleware now supports custom header locations beyond the standard Authorization header. You can specify any header name to retrieve JWT tokens from.

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

const app = new Hono()

app.use(
  '/api/*',
  jwt({
    secret: 'secret-key',
    headerName: 'X-Auth-Token', // Custom header name
  })
)

app.get('/api/protected', (c) => {
  return c.json({ message: 'Protected resource' })
})

This is useful when working with APIs that use non-standard authentication headers.

Thanks @​kunalbhagawati!

JSX Streaming Nonce Support

JSX streaming now supports nonce values for Content Security Policy (CSP) compliance. The streaming context can include a nonce that gets applied to inline scripts.

import { Hono } from 'hono'
import {
  renderToReadableStream,
  Suspense,
  StreamingContext,
} from 'hono/jsx/streaming'

const app = new Hono()

app.get('/', (c) => {
  const stream = renderToReadableStream(
    <html>
      <body>
        <StreamingContext
          value={{ scriptNonce: 'random-nonce-value' }}
        >
          <Suspense fallback={<div>Loading...</div>}>
            <AsyncComponent />
          </Suspense>
        </StreamingContext>
      </body>
    </html>
  )

  return c.body(stream, {
    headers: {
      'Content-Type': 'text/html; charset=UTF-8',
      'Transfer-Encoding': 'chunked',
      'Content-Security-Policy':
        "script-src 'nonce-random-nonce-value'",
    },
  })
})

Thanks @​usualoma!

CORS Dynamic allowedMethods

CORS middleware now supports dynamic allowedMethods based on the request origin. You can provide a function that returns different allowed methods depending on the origin.

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

const app = new Hono()

app.use(
  '*',
  cors({
    origin: ['https://example.com', 'https://api.example.com'],
    allowMethods: (origin) => {
      if (origin === 'https://api.example.com') {
        return ['GET', 'POST', 'PUT', 'DELETE']
      }
      return ['GET', 'POST'] // Default for other origins
    },
  })
)

This enables fine-grained control over CORS policies per origin.

Thanks @​Kanahiro!

JWK Allow Anonymous Access

JWK middleware now supports anonymous access with the allow_anon option. When enabled, requests without valid tokens can still proceed to your handlers.

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

const app = new Hono()

app.use(
  '/api/*',
  jwk({
    jwks_uri: 'https://example.com/.well-known/jwks.json',
    allow_anon: true,
  })
)

app.get('/api/data', (c) => {
  const payload = c.get('jwtPayload')
  if (payload) {
    return c.json({ message: 'Authenticated user', user: payload })
  }
  return c.json({ message: 'Anonymous access' })
})

Additionally, keys and jwks_uri options now support functions that receive the context, enabling dynamic key resolution.

Thanks @​Beyondo!

Cache Status Codes Option

Cache middleware now allows you to specify which status codes should be cached using the cacheableStatusCodes option.

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

const app = new Hono()

app.use(
  '*',
  cache({
    cacheName: 'my-cache',
    cacheControl: 'max-age=3600',
    cacheableStatusCodes: [200, 404], // Cache both success and not found responses
  })
)

Thanks @​miyamo2!

Service Worker fire() Function

A new fire() function is available from the Service Worker adapter, providing a cleaner alternative to app.fire().

import { Hono } from 'hono'
import { fire } from 'hono/service-worker'

const app = new Hono()

app.get('/', (c) => c.text('Hello from Service Worker!'))

// Use the standalone fire function
fire(app)

The app.fire() method is now deprecated in favor of this approach. Goodbye app.fire().

SSG Plugin System

Static Site Generation (SSG) now supports a plugin system that allows you to extend the generation process with custom functionality.

For example, the following is easy implementation of a sitemap plugin:

// plugins.ts
import fs from 'node:fs/promises'
import path from 'node:path'
import type { SSGPlugin } from 'hono/ssg'
import { DEFAULT_OUTPUT_DIR } from 'hono/ssg'

export const sitemapPlugin = (baseURL: string): SSGPlugin => {
  return {
    afterGenerateHook: (result, fsModule, options) => {
      const outputDir = options?.dir ?? DEFAULT_OUTPUT_DIR
      const filePath = path.join(outputDir, 'sitemap.xml')
      const urls = result.files.map((file) =>
        new URL(file, baseURL).toString()
      )
      const siteMapText = `<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
${urls.map((url) => `<url><loc>${url}</loc></url>`).join('\n')}
</urlset>`
      fsModule.writeFile(filePath, siteMapText)
    },
  }
}

Applying the plugin:

import { toSSG } from 'hono/ssg'
import { sitemapPlugin } from './plugins'

toSSG(app, fs, {
  plugins: [sitemapPlugin('https://example.com')],
})

Plugins can hook into various stages of the generation process to perform custom actions.

Thanks @​3w36zj6!

Third-party Middleware Updates

In addition to core Hono features, we're excited to introduce new third-party middleware packages that extend Hono's capabilities.

MCP Middleware

A new middleware package @hono/mcp enables creating remote MCP (Model Context Protocol) servers over Streamable HTTP Transport. This is the initial release with more features planned for the future.

import { McpServer } from '@&#8203;modelcontextprotocol/sdk/server/mcp.js'
import { StreamableHTTPTransport } from '@&#8203;hono/mcp'
import { Hono } from 'hono'

const app = new Hono()

// Your MCP server implementation
const mcpServer = new McpServer({
  name: 'my-mcp-server',
  version: '1.0.0',
})

app.all('/mcp', async (c) => {
  const transport = new StreamableHTTPTransport()
  await mcpServer.connect(transport)
  return transport.handleRequest(c)
})

Currently, this is ideal for creating stateless and authentication-less remote MCP servers.

Thanks @​MathurAditya724!

UA Blocker Middleware

The new @hono/ua-blocker middleware allows blocking requests based on user agent headers. It includes blocking AI bots functions.

import { uaBlocker } from '@&#8203;hono/ua-blocker'
import { aiBots } from '@&#8203;hono/ua-blocker/ai-bots'
import { Hono } from 'hono'

const app = new Hono()

// Block specific user agents
app.use(
  '*',
  uaBlocker({
    blocklist: ['ForbiddenBot', 'Not You'],
  })
)

// Block all AI bots
app.use(
  '*',
  uaBlocker({
    blocklist: aiBots,
  })
)

// Serve robots.txt to discourage AI bots
app.use('/robots.txt', useAiRobotsTxt())

Thanks @​finxol!

Zod Validator v4 Support

The @hono/zod-validator middleware now supports Zod v4!

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 '@&#8203;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!
