## Update Router
|
|
|
|
Update to the latest version version of the router.
|
|
|
|
```bash
|
|
npm i -D @tsndr/cloudflare-worker-router@^3
|
|
```
|
|
|
|
|
|
## Handlers
|
|
|
|
- Remove `res` and `next` from handler parameter list.
|
|
- Replace `res.` with `return new Response()` / `return Response.json()`.
|
|
- Remove `next()` calls from middlewares.
|
|
|
|
|
|
### Before
|
|
|
|
```typescript
|
|
// Register global middleware
|
|
router.use(({ env, req, res, next }) => {
|
|
if (req.headers.get('authorization') !== env.SECRET_TOKEN) {
|
|
res.status = 401
|
|
return
|
|
}
|
|
|
|
next()
|
|
})
|
|
|
|
// Simple get
|
|
router.get('/user', ({ res }) => {
|
|
res.body = {
|
|
id: 1,
|
|
name: 'John Doe'
|
|
}
|
|
})
|
|
```
|
|
|
|
|
|
### After
|
|
|
|
```typescript
|
|
// Register global middleware
|
|
router.use(({ env, req }) => {
|
|
// Intercept if token doesn't match
|
|
if (req.headers.get('authorization') !== env.SECRET_TOKEN) {
|
|
return new Response(null, { status: 401 })
|
|
}
|
|
})
|
|
|
|
// Simple get
|
|
router.get('/user', () => {
|
|
return Response.json({
|
|
id: 1,
|
|
name: 'John Doe'
|
|
})
|
|
})
|
|
```
