Release Notes

Hono v4.12.0 is now available!

This release includes new features for the Hono client, middleware improvements, adapter enhancements, and significant performance improvements to the router and context.

$path for Hono Client

The Hono client now has a $path() method that returns the path string instead of a full URL. This is useful when you need just the path portion for routing or key-based operations:

const client = hc<typeof app>('http://localhost:8787')

// Get the path string
const path = client.api.posts.$path()
// => '/api/posts'

// With path parameters
const postPath = client.api.posts[':id'].$path({
  param: { id: '123' },
})
// => '/api/posts/123'

// With query parameters
const searchPath = client.api.posts.$path({
  query: { filter: 'test' },
})
// => '/api/posts?filter=test'

Unlike $url() which returns a URL object, $path() returns a plain path string, making it convenient for use with routers or as cache keys.

Thanks @​ShaMan123!

ApplyGlobalResponse Type Helper for RPC Client

The new ApplyGlobalResponse type helper allows you to add global error response types to all routes in the RPC client. This is useful for typing common error responses from app.onError() or global middlewares:

const app = new Hono()
  .get('/api/users', (c) => c.json({ users: ['alice', 'bob'] }, 200))
  .onError((err, c) => c.json({ error: err.message }, 500))

type AppWithErrors = ApplyGlobalResponse<
  typeof app,
  {
    401: { json: { error: string; message: string } }
    500: { json: { error: string; message: string } }
  }
>

const client = hc<AppWithErrors>('http://api.example.com')
// Now client knows about both success and error responses
const res = await client.api.users.$get()
// InferResponseType includes { users: string[] } | { error: string; message: string }

Thanks @​mohankumarelec!

SSG Redirect Plugin

A new redirectPlugin for SSG generates static HTML redirect pages for HTTP redirect responses (301, 302, 303, 307, 308):

import { toSSG } from 'hono/ssg'
import { defaultPlugin, redirectPlugin } from 'hono/ssg'

const app = new Hono()
app.get('/old', (c) => c.redirect('/new'))
app.get('/new', (c) => c.html('New Page'))

// redirectPlugin must be placed before defaultPlugin
await toSSG(app, fs, {
  plugins: [redirectPlugin(), defaultPlugin()],
})

The generated redirect pages include a <meta http-equiv="refresh"> tag, a canonical link, and a robots noindex meta tag.

Thanks @​3w36zj6!

onAuthSuccess Callback for Basic Auth

The Basic Auth middleware now supports an onAuthSuccess callback that is invoked after successful authentication. This allows you to set context variables or perform logging without re-parsing the Authorization header:

app.use(
  '/auth/*',
  basicAuth({
    username: 'hono',
    password: 'ahotproject',
    onAuthSuccess: (c, username) => {
      c.set('user', { name: username, role: 'admin' })
      console.log(`User ${username} authenticated`)
    },
  })
)

The callback also works with async functions and the verifyUser mode.

Thanks @​AprilNEA!

getConnInfo for AWS Lambda, Cloudflare Pages, and Netlify

getConnInfo() is now available for three additional adapters:

// AWS Lambda (supports API Gateway v1, v2, and ALB)
import { handle, getConnInfo } from 'hono/aws-lambda'

// Cloudflare Pages
import { handle, getConnInfo } from 'hono/cloudflare-pages'

// Netlify
import { handle, getConnInfo } from 'hono/netlify'

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

Thanks @​rokasta12!

alwaysRedirect Option for Trailing Slash Middleware

The trailing slash middleware now supports an alwaysRedirect option. When enabled, the middleware redirects before executing handlers, which fixes the issue where trailing slash handling doesn't work with wildcard routes:

app.use(trimTrailingSlash({ alwaysRedirect: true }))

app.get('/my-path/*', async (c) => {
  return c.text('wildcard')
})

// /my-path/something/ will be redirected to /my-path/something
// before the wildcard handler is executed

Progressive Locale Code Truncation

The normalizeLanguage function in the language middleware now supports RFC 4647 Lookup-based progressive truncation. Locale codes like ja-JP will match ja when only the base language is in supportedLanguages:

app.use(
  '/*',
  languageDetector({
    supportedLanguages: ['en', 'ja'],
    fallbackLanguage: 'en',
    order: ['cookie', 'header'],
  })
)

// Accept-Language: ja-JP → matches 'ja'
// Accept-Language: ko-KR → falls back to 'en'

Thanks @​sorafujitani!

exports Field for ExecutionContext

The ExecutionContext type now includes an exports property for Cloudflare Workers. You can use module augmentation to type it with Wrangler's generated types:

import 'hono'

declare module 'hono' {
  interface ExecutionContext {
    readonly exports: Cloudflare.Exports
  }
}

Thanks @​toreis-up!

Performance Improvements

TrieRouter 1.5x ~ 2.0x Faster

The TrieRouter has been significantly optimized with reduced spread syntax usage, O(1) hasChildren checks, lazy regular expression generation, and removal of redundant processes:

Route	Node.js	Deno	Bun
short static GET /user	1.70x	1.40x	1.34x
dynamic GET /user/lookup/username/hey	1.38x	1.69x	1.51x
wildcard GET /static/index.html	1.51x	1.72x	1.43x
all together	1.58x	1.60x	1.82x

Thanks @​EdamAme-x!

Fast Path for c.json()

c.json() now has the same fast path optimization as c.text(). When no custom status, headers, or finalized state exists, the Response is created directly without allocating a Headers object:

// This common pattern is now faster
return c.json({ message: 'Hello' })

Benchmark results:

Metric	Before	After	Change
Reqs/sec	92,268	95,244	+3.2%
Latency	5.42ms	5.25ms	-3.1%
Throughput	17.24MB/s	19.07MB/s	+10.6%

Thanks @​mgcrea!
