learning express step(八)
To skip the rest of the middleware functions from a router middleware stack, call next('route')
to pass control to the next route.
const express = require('express');
const app = express(); app.get('/user/:id', function (req, res, next) {
if (req.params.id === '') next('route')
else next()
}, function (req, res, next) {
res.send('regular');
}
); app.get('/user/:id', function (req, res, next) {
res.send('special');
}); app.listen();
