const router = express.Router()

// validating the querystring
router.get(
  '/querystring',
  validateSchema().query(someSchema),
  (req, res) => { res.send(someBody) }
)

// validating the params
router.get(
  '/params/:id',
  validateSchema().params(someSchema),
  (req, res) => { res.send(someBody) }

// validating the body
router.post(
  '/body',
  validateSchema().body(someSchema),
  (req, res) => { res.send(someBody) }
)

// validating the headers

// validating params, body and header
router.put(

  validateSchema().params(someSchema),
  validateSchema()
    .body(Joi.object().keys({name: Joi.string().required()})),
