How do you create middleware for a specific route and method?

[OultimoCoder]

Say I wanted to validate the parameters for a post request using middleware but not affect the other methods like get etc, I would like to be able to do:

const route = app.route('/users')
route.post('/', validate(userValidation.createUser), userController.createUser)

But that isn't possible, the only way I can see to do it currently is:

const route = app.route('/users')
app.user('/users', validate(userValidation.createUser))
route.post('/', userController.createUser)

But this does it for all methods in the /users route, I could check in the middleware for the route method but this isn't ideal. Is there a way to do this that I am missing?

Hi @OultimoCoder

We were just talking about it! #189

If this comes true, we can write this way.

const route = app.route('/users')
route.post('/', validate(userValidation.createUser), userController.createUser)

We are planning to release the Hono including this feature. Maybe it's v1.2.0.

Before it is released, you can write like this:

const mid = async (c: Context, next) => {
  await next()
  c.header('x-custom', 'abc')
}

app.use('*', async (c, next) => {
  if (c.req.method === 'GET') {
    await mid(c, next)
  } else {
    await next()
  }
})

app.get('/', (c) => {
  return c.text('Hello')
})

Thank you!

Oh haha that's awesome that it's in progress. I hope the 1.2 release is coming soon! I'm building an Api using Hono and the new features will be super helpful!

You can write like this:

const app = new Hono()
const route = new Route()

route.post('/', validate(userValidation.createUser), userController.createUser)
app.route('/users', route)
