2Sa 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.
3~
4Ang [Hono](https://hono.dev) (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.

6## Bakit Hono
7~
81. **Performance.** Pinagsasama-sama ng `RegExpRouter` ang lahat ng route patterns sa isang regex. Lumalampas ang benchmarks sa 400,000 ops/s.
92. **Portability.** Web Standards ay nangangahulugang zero Node dependencies.
103. **TypeScript-first DX.** Ang path parameters ay na-i-infer bilang literal types, end-to-end type-safe RPC client.

28## Pagsisimula
29~
30```bash
31npm create hono@latest my-api
32cd my-api
33npm install
34npm run dev
35```
36~
37```typescript
38// src/index.ts
39import { Hono } from 'hono'
40~
41const app = new Hono()
42~
43app.get('/', (c) => c.text('Hello Hono!'))
44~
45export default app
46```
47~
48Sa 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`.
49~
50## Routing
51~
52```typescript
53import { Hono } from 'hono'
54~
55const app = new Hono()
56~
57app.get('/', (c) => c.text('Home'))
58app.get('/posts/:id', (c) => {
59  const id = c.req.param('id')
60  return c.json({ id })
61})
62app.get('/posts/:id/comments/:commentId', (c) => {
63  const { id, commentId } = c.req.param()
64  return c.json({ id, commentId })
65})
66app.get('/files/*', (c) => c.text('Wildcard'))
67app.post('/posts', async (c) => {
68  const body = await c.req.json()
69  return c.json({ created: body }, 201)
70})
71```
72~
73### Pag-grupo ng routes
74~
75```typescript
76// routes/posts.ts
77import { Hono } from 'hono'
78~
79const posts = new Hono()
80posts.get('/', (c) => c.json({ posts: [] }))
81posts.get('/:id', (c) => c.json({ id: c.req.param('id') }))
82export default posts
83~
84// src/index.ts
85import { Hono } from 'hono'
86import posts from './routes/posts'
87~
88const app = new Hono()
89app.route('/posts', posts)
90```
91~
92## Ang Context object
93~
94```typescript
95app.post('/echo', async (c) => {
96  const userAgent = c.req.header('User-Agent')
97  const page = c.req.query('page')
98  const body = await c.req.json()
99  const env = c.env
100~
101  c.set('requestId', crypto.randomUUID())
102  const id = c.get('requestId')
103~
104  c.header('X-Request-Id', id)
105  c.status(200)
106  return c.json({ userAgent, page, body, id })
107})
108```
109~
110## Middleware: ang onion model
111~
112```typescript
113import { Hono } from 'hono'
114import { logger } from 'hono/logger'
115import { cors } from 'hono/cors'
116import { secureHeaders } from 'hono/secure-headers'

119~
120app.use('*', logger())
121app.use('*', secureHeaders())
122app.use('/api/*', cors({ origin: 'https://spinny.dev' }))
123~
124app.use('*', async (c, next) => {
125  const start = performance.now()
126  await next()
127  c.header('X-Response-Time', `${performance.now() - start}ms`)
128})
129```

131### Built-in middleware
132~
133| Middleware | Layunin |
134|-----------|---------|
135| `logger` | Structured logs ng method, path, status, duration |
136| `cors` | CORS na configurable ayon sa origin, methods, headers |
137| `csrf` | Origin-based CSRF protection |
138| `secureHeaders` | Nagse-set ng CSP, HSTS, X-Frame-Options |
139| `bearerAuth` / `basicAuth` | Out-of-the-box Bearer/Basic auth |
140| `jwt` | JWT verify/sign gamit ang `jose` |
141| `etag` | Bumubuo ng ETag at hinahawakan ang 304 |
142| `cache` | Cache sa pamamagitan ng Web Cache API |
143| `compress` | gzip/deflate sa response |
144| `bodyLimit` | Tinatanggihan ang bodies na lampas sa threshold |
145| `timing` | Server-Timing header para sa profiling |
146~
147### Type-safe custom middleware
148~
149```typescript

255## Routers at performance
256~
257| Router | Lakas | Kailan gamitin |
258|--------|-----------|-------------|
259| `RegExpRouter` | Pinakamabilis, compiled regex | Default para sa karamihan ng APIs |
260| `TrieRouter` | Sumusuporta sa lahat ng patterns | Kumplikadong patterns na hindi kayang hawakan ng RegExp |
261| `SmartRouter` | Awtomatikong pumipili ng pinakamahusay | Inirerekomendang default |
262| `LinearRouter` | Ultra-bilis na registration | One-shot workers, kritikal na cold start |
263| `PatternRouter` | Pinakamaliit na bundle (<15KB) | Sukdulang limitasyon sa laki |
264~
265```typescript

390export type AppType = typeof api
391export default app

393~
394## Pagsubok
395~
396```typescript
397import { describe, it, expect } from 'vitest'
398import app from '../src/index'
399~
400describe('GET /api/posts', () => {
401  it('nagbabalik ng listahan ng mga post', async () => {
402    const res = await app.request('/api/posts')
403    expect(res.status).toBe(200)
404    const body = await res.json()
405    expect(body.posts).toBeInstanceOf(Array)
406  })
407})
408```
409~
410## Best practices
411~
412### 1. I-chain ang mga route definition
413~
414```typescript
415const app = new Hono()
416  .get('/posts', handler1)
417  .post('/posts', handler2)
418  .get('/posts/:id', handler3)
419```
420~
421### 2. I-export ang type, hindi ang implementation
422~
423Ang client ay dapat mag-import ng `AppType`.
424~
425### 3. Isang router bawat domain
426~
427Sub-app para sa `posts`, `users`, `webhooks`.
428~
429### 4. Validation sa gilid, palagi
430~
431Bawat external input ay dapat dumaan sa `zValidator`.
432~
433### 5. Umasa sa bindings, hindi sa global clients
434~
435Sa Cloudflare, i-access ang KV/D1/R2 sa pamamagitan ng `c.env`.
436~
437### 6. Sukatin bago i-optimize ang router
438~
439Ang default na `SmartRouter` ay angkop sa 95% ng mga kaso.
440~
441## Konklusyon
442~
443Naging de facto standard ang Hono noong 2026 para sa pagbuo ng edge-ready APIs sa TypeScript.
444~
445> **Checklist sa pagsisimula:**
446>
447> - [x] `npm create hono@latest` at piliin ang iyong runtime template
448> - [x] I-define ang routes na may chaining (`.get(...).post(...)`)
449> - [x] Idagdag ang `logger`, `cors`, `secureHeaders` bilang global middleware
450> - [x] I-validate ang bawat input gamit ang `@hono/zod-validator`
451> - [x] I-export ang `AppType` at konsumihin ang API gamit ang type-safe `hc` client
452> - [x] Sumulat ng tests gamit ang `app.request()` — walang HTTP server na kailangan
453> - [x] I-deploy gamit ang `wrangler deploy` (CF), `vercel deploy` o ang bundler ng iyong runtime
