but why a right minded person will create custom response on this kind of thing

Hi @Lucifer359-IV, for example, you can do that

app.get('/ws', c => {
  if (!validToken(c.req.query('token'))) {
    return c.text('Unauthorized', 400)
  }
  return upgradeWebSocket(c, {
    onOpen () {
      console.log('opened!')
    }
  })
})

Also you can change the response with or without the upgrade header.

@nakasyou can't you do that token validation with a middleware?

Also have you checked the streaming helper section in the docs?

@JakeChampion

Yes, but it expand the options.
Also, currently, c.req.param is not typed.

app.get('/:id', upgradeWebSocket((c) => {
  c.req.param('id') // not typed
}))

To implement this, the problem will be resolved.

Also have you checked the streaming helper section in the docs?

Yes. I used "like a stream" in the sense of generating a response, not as a middleware, but that expression may not be appropriate. I will change the title. Thanks.
