Hono: ang ultra-bilis na web framework na nakabase sa Web Standards

Sa loob ng maraming taon, ang pagpili ng JavaScript web framework ay nangangahulugang pagtanggap ng trade-off: ang Express ay universal pero mabagal at nakatali sa Node, ang Fastify ay mabilis pero Node lang, ang Next.js ay full-featured pero mabigat. Nang dumating ang edge runtimes — Cloudflare Workers, Deno Deploy, Bun, Vercel Edge — ipinakita ng mga framework na iyon ang kanilang mga limitasyon.

Ang Hono (Hapon para sa "apoy" 🔥) ay ang modernong sagot. Isang framework na mababa sa 14KB, ganap na nakabase sa Web Standards (Request, Response, fetch), na tumatakbo saanman may JavaScript runtime. Ang parehong code ay nade-deploy sa Cloudflare Workers, Bun, Deno, Node.js, Vercel, Netlify at AWS Lambda — nang walang pagbabago.

Bakit Hono

1. Performance. Pinagsasama-sama ng RegExpRouter ang lahat ng route patterns sa isang regex. Lumalampas ang benchmarks sa 400,000 ops/s.
2. Portability. Web Standards ay nangangahulugang zero Node dependencies.
3. TypeScript-first DX. Ang path parameters ay na-i-infer bilang literal types, end-to-end type-safe RPC client.

Pagsisimula

npm create hono@latest my-api
cd my-api
npm install
npm run dev

// src/index.ts
import { Hono } from 'hono'

const app = new Hono()

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

export default app

Sa Cloudflare Workers, sapat na ito. Sa Bun: Bun.serve({ fetch: app.fetch, port: 3000 }). Sa Node: serve({ fetch: app.fetch }) mula sa @hono/node-server.

Routing

import { Hono } from 'hono'

const app = new Hono()

app.get('/', (c) => c.text('Home'))
app.get('/posts/:id', (c) => {
  const id = c.req.param('id')
  return c.json({ id })
})
app.get('/posts/:id/comments/:commentId', (c) => {
  const { id, commentId } = c.req.param()
  return c.json({ id, commentId })
})
app.get('/files/*', (c) => c.text('Wildcard'))
app.post('/posts', async (c) => {
  const body = await c.req.json()
  return c.json({ created: body }, 201)
})

Pag-grupo ng routes

// routes/posts.ts
import { Hono } from 'hono'

const posts = new Hono()
posts.get('/', (c) => c.json({ posts: [] }))
posts.get('/:id', (c) => c.json({ id: c.req.param('id') }))
export default posts

// src/index.ts
import { Hono } from 'hono'
import posts from './routes/posts'

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

Ang Context object

app.post('/echo', async (c) => {
  const userAgent = c.req.header('User-Agent')
  const page = c.req.query('page')
  const body = await c.req.json()
  const env = c.env

  c.set('requestId', crypto.randomUUID())
  const id = c.get('requestId')

  c.header('X-Request-Id', id)
  c.status(200)
  return c.json({ userAgent, page, body, id })
})

Middleware: ang onion model

import { Hono } from 'hono'
import { logger } from 'hono/logger'
import { cors } from 'hono/cors'
import { secureHeaders } from 'hono/secure-headers'

const app = new Hono()

app.use('*', logger())
app.use('*', secureHeaders())
app.use('/api/*', cors({ origin: 'https://spinny.dev' }))

app.use('*', async (c, next) => {
  const start = performance.now()
  await next()
  c.header('X-Response-Time', `${performance.now() - start}ms`)
})

Built-in middleware

Type-safe custom middleware

import { createMiddleware } from 'hono/factory'

type AuthVars = { userId: string; role: 'user' | 'admin' }

export const requireAuth = createMiddleware<{ Variables: AuthVars }>(
  async (c, next) => {
    const token = c.req.header('Authorization')?.replace('Bearer ', '')
    if (!token) return c.json({ error: 'Unauthorized' }, 401)

    const payload = await verifyJwt(token)
    c.set('userId', payload.sub)
    c.set('role', payload.role)
    await next()
  }
)

app.get('/me', requireAuth, (c) => {
  const userId = c.var.userId
  return c.json({ userId })
})

Validation gamit ang Zod

import { Hono } from 'hono'
import { zValidator } from '@hono/zod-validator'
import { z } from 'zod'

const createPost = z.object({
  title: z.string().min(1).max(200),
  body: z.string().min(1),
  tags: z.array(z.string()).default([]),
})

app.post(
  '/posts',
  zValidator('json', createPost),
  (c) => {
    const data = c.req.valid('json')
    return c.json({ ok: true, post: data }, 201)
  }
)

RPC: end-to-end type-safe client

// server.ts
import { Hono } from 'hono'
import { zValidator } from '@hono/zod-validator'
import { z } from 'zod'

const app = new Hono()
  .get('/posts/:id', (c) =>
    c.json({ id: c.req.param('id'), title: 'Hello' })
  )
  .post(
    '/posts',
    zValidator('json', z.object({ title: z.string(), body: z.string() })),
    (c) => c.json({ ok: true }, 201)
  )

export type AppType = typeof app
export default app

// client.ts
import { hc } from 'hono/client'
import type { AppType } from './server'

const client = hc<AppType>('https://api.spinny.dev')

const res = await client.posts[':id'].$get({ param: { id: '42' } })
if (res.ok) {
  const data = await res.json()
  console.log(data.title)
}

const created = await client.posts.$post({
  json: { title: 'Kumusta', body: 'Ang Hono ay isang apoy' },
})

Status code discrimination

.get('/posts/:id', (c) => {
  const post = findPost(c.req.param('id'))
  if (!post) return c.json({ error: 'not found' }, 404)
  return c.json({ post }, 200)
})

const res = await client.posts[':id'].$get({ param: { id } })
if (res.status === 404) {
  const { error } = await res.json()
}
if (res.status === 200) {
  const { post } = await res.json()
}

Routers at performance

import { Hono } from 'hono'
import { LinearRouter } from 'hono/router/linear-router'

const app = new Hono({ router: new LinearRouter() })

Multi-runtime deploy

Cloudflare Workers

import { Hono } from 'hono'

type Bindings = { MY_KV: KVNamespace; DB: D1Database }
const app = new Hono<{ Bindings: Bindings }>()

app.get('/cache/:key', async (c) => {
  const value = await c.env.MY_KV.get(c.req.param('key'))
  return c.json({ value })
})

export default app

Deploy: npx wrangler deploy.

Bun

import { Hono } from 'hono'
const app = new Hono()
app.get('/', (c) => c.text('Bun + Hono'))

Bun.serve({ fetch: app.fetch, port: 3000 })

Node.js

import { serve } from '@hono/node-server'
import { Hono } from 'hono'

const app = new Hono()
app.get('/', (c) => c.text('Node + Hono'))

serve({ fetch: app.fetch, port: 3000 })

Deno

import { Hono } from 'jsr:@hono/hono'
const app = new Hono()
app.get('/', (c) => c.text('Deno + Hono'))
Deno.serve(app.fetch)

Vercel

// api/[[...route]].ts
import { Hono } from 'hono'
import { handle } from 'hono/vercel'

const app = new Hono().basePath('/api')
app.get('/hello', (c) => c.json({ msg: 'Hello from Vercel' }))

export const GET = handle(app)
export const POST = handle(app)

Praktikal na halimbawa: REST API na may auth at DB

import { Hono } from 'hono'
import { jwt } from 'hono/jwt'
import { logger } from 'hono/logger'
import { cors } from 'hono/cors'
import { zValidator } from '@hono/zod-validator'
import { z } from 'zod'

type Bindings = { DB: D1Database; JWT_SECRET: string }
type Variables = { jwtPayload: { sub: string } }

const app = new Hono<{ Bindings: Bindings; Variables: Variables }>()

app.use('*', logger())
app.use('/api/*', cors({ origin: 'https://spinny.dev', credentials: true }))

const auth = (c: any, next: any) =>
  jwt({ secret: c.env.JWT_SECRET })(c, next)

const api = app.basePath('/api')

api.get('/posts', async (c) => {
  const { results } = await c.env.DB
    .prepare('SELECT id, title, created_at FROM posts ORDER BY created_at DESC LIMIT 50')
    .all()
  return c.json({ posts: results })
})

api.post(
  '/posts',
  auth,
  zValidator('json', z.object({
    title: z.string().min(1).max(200),
    body: z.string().min(1),
  })),
  async (c) => {
    const { title, body } = c.req.valid('json')
    const userId = c.var.jwtPayload.sub
    const result = await c.env.DB
      .prepare('INSERT INTO posts (title, body, author_id) VALUES (?, ?, ?) RETURNING id')
      .bind(title, body, userId)
      .first<{ id: number }>()
    return c.json({ id: result?.id }, 201)
  }
)

api.onError((err, c) => {
  console.error(err)
  return c.json({ error: 'Internal error' }, 500)
})

export type AppType = typeof api
export default app

Pagsubok

import { describe, it, expect } from 'vitest'
import app from '../src/index'

describe('GET /api/posts', () => {
  it('nagbabalik ng listahan ng mga post', async () => {
    const res = await app.request('/api/posts')
    expect(res.status).toBe(200)
    const body = await res.json()
    expect(body.posts).toBeInstanceOf(Array)
  })
})

Best practices

1. I-chain ang mga route definition

const app = new Hono()
  .get('/posts', handler1)
  .post('/posts', handler2)
  .get('/posts/:id', handler3)

2. I-export ang type, hindi ang implementation

Ang client ay dapat mag-import ng AppType.

3. Isang router bawat domain

Sub-app para sa posts, users, webhooks.

4. Validation sa gilid, palagi

Bawat external input ay dapat dumaan sa zValidator.

5. Umasa sa bindings, hindi sa global clients

Sa Cloudflare, i-access ang KV/D1/R2 sa pamamagitan ng c.env.

6. Sukatin bago i-optimize ang router

Ang default na SmartRouter ay angkop sa 95% ng mga kaso.

Konklusyon

Naging de facto standard ang Hono noong 2026 para sa pagbuo ng edge-ready APIs sa TypeScript.

Checklist sa pagsisimula:

• npm create hono@latest at piliin ang iyong runtime template
• I-define ang routes na may chaining (.get(...).post(...))
• Idagdag ang logger, cors, secureHeaders bilang global middleware
• I-validate ang bawat input gamit ang @hono/zod-validator
• I-export ang AppType at konsumihin ang API gamit ang type-safe hc client
• Sumulat ng tests gamit ang app.request() — walang HTTP server na kailangan
• I-deploy gamit ang wrangler deploy (CF), vercel deploy o ang bundler ng iyong runtime
