apply middleware on a set of routes

[webdeb]

I tried to understand the code in router.ts but I still could't figure out how to use a middleware for only a set of routes, however this did't not work and I also could not find any documentation how I could do it.

const router = new Router()

// public route
router.get("/", ctx => {
  ctx.response.body = "OK"
})

const protectService = (ctx, next) => {
  if (hasSecretKeyInHeader(ctx)) {
    return next()
  } else {
    ctx.response.status = 401
  }
}

router
  .post("/service1", service1)
  .post("/service2", service2)
  .use(protectService)

app.use(router.routes())

Is this even possible?

Or is the only way to go:

router.post("/service1", protectService, service1)
router.post("/service2", protectService, service2)

Oh, I think I got it. Define multiple routers:

const publicRouter = new Router()
publicRouter
  .get(...)

const serviceRouter = new Router()
serviceRouter
  .use(protectService)
  .post(...)
  .post(...)

app.use(publicRouter.routes())
app.use(serviceRouter.routes())
