Middleware

#live demo #source code

You can add middleware to the router. Middlwares will be called in order before executing each route handler. It's useful to parse request object.

import SMERouter from 'sme-router'

const router = new SMERouter('router-view')

router.use((req) => {
  req.body.count += 3
})

router.use((req) => {
  req.body.count *= 2
})

router.use((req) => {
  req.body.order = `NO.${req.body.count}`
})

router.route('/user/:name', (req, res, next) => {
  console.log(req.body.count) // output => 8
  console.log(req.body.order) // output => NO.8
})

router.go('/user/Leo', { count: 1 })
