Hono: Framework Web Ultracepat Berbasis Web Standards

Selama bertahun-tahun, memilih framework web JavaScript berarti menerima trade-off: Express universal tapi lambat dan terikat Node, Fastify cepat tapi hanya Node, Next.js lengkap tapi berat. Saat runtime edge — Cloudflare Workers, Deno Deploy, Bun, Vercel Edge — muncul, framework-framework itu menunjukkan batasannya: dependensi tidak kompatibel, bundle besar, API terikat pada req/res Node.

Hono (Jepang untuk "api" 🔥) adalah jawaban modern. Framework di bawah 14KB, sepenuhnya dibangun di atas Web Standards (Request, Response, fetch), berjalan di mana saja ada runtime JavaScript. Kode yang sama dideploy ke Cloudflare Workers, Bun, Deno, Node.js, Vercel, Netlify, dan AWS Lambda — tanpa perubahan.

Mengapa Hono

Hono melakukan tiga hal lebih baik dari siapa pun:

1. Performa. RegExpRouter mengompilasi semua pola route ke satu regex, menghindari loop linear router tradisional. Benchmark melampaui 400.000 ops/s.
2. Portabilitas. Web Standards berarti nol dependensi Node. app.fetch yang sama diekspor sebagai default di Cloudflare Worker, dilewatkan ke Bun.serve, dimount di server Deno, atau diadaptasi dengan @hono/node-server.
3. DX TypeScript-first. Path parameter diinferensi sebagai literal type, klien RPC type-safe end-to-end, validator yang menginferensi tipe input dan output.

Memulai

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

Starter menanyakan template mana: cloudflare-workers, bun, deno, nodejs, vercel, aws-lambda, nextjs dan lainnya. Untuk uji coba cepat, bisa juga mulai dari satu file:

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

const app = new Hono()

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

export default app

Di Cloudflare Workers itu cukup. Di Bun: Bun.serve({ fetch: app.fetch, port: 3000 }). Di Node: serve({ fetch: app.fetch }) dari @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') // string, bertipe
  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)
})

Parameter diinferensi sebagai literal type: TypeScript tahu c.req.param('id') mengembalikan string hanya jika Anda mendeklarasikan :id di pola. Salah ketik adalah error compile-time.

Mengelompokkan rute

// 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)

Objek Context

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 })
})

Metode response utama: c.text, c.json, c.html, c.body (raw), c.redirect.

Middleware: model bawang

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`)
})

await next() menyerahkan kontrol ke middleware berikutnya.

Middleware bawaan

Middleware kustom type-safe

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 })
})

Validasi dengan 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: klien type-safe end-to-end

// 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: 'Halo', body: 'Hono adalah api' },
})

Diskriminasi status code

.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()
}

Router dan performa

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

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

Deploy multi-runtime

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)

Contoh praktis: REST API dengan auth dan 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

Testing

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

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

Praktik terbaik

1. Rangkai definisi rute

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

2. Ekspor tipe, bukan implementasi

Klien harus mengimpor AppType. import type memastikan build frontend tidak menyertakan kode backend.

3. Satu router per domain

Sub-app untuk posts, users, webhooks. Komposisi via app.route().

4. Validasi di tepi, selalu

Setiap input eksternal harus melewati zValidator.

5. Bersandar pada bindings, bukan klien global

Di Cloudflare, akses KV/D1/R2 via c.env.

6. Ukur sebelum mengoptimalkan router

SmartRouter default cocok untuk 95% kasus.

Kesimpulan

Hono telah menjadi standar de facto pada 2026 untuk membangun API edge-ready dengan TypeScript. Kombinasi Web Standards, performa, type safety, dan portabilitas memecahkan tepat masalah-masalah yang menahan framework tradisional.

Checklist memulai:

• npm create hono@latest dan pilih template runtime Anda
• Definisikan rute dengan chaining (.get(...).post(...))
• Tambahkan logger, cors, secureHeaders sebagai middleware global
• Validasi setiap input dengan @hono/zod-validator
• Ekspor AppType dan konsumsi API dengan klien hc type-safe
• Tulis tes dengan app.request() — tanpa server HTTP
• Deploy dengan wrangler deploy (CF), vercel deploy, atau bundler runtime Anda
