path in express code example

Example 1: express request path

// GET 'http://www.example.com/admin/new?a=b'
app.get('/admin', (req, res, next) => {
  req.originalUrl; // '/admin/new?a=b' (full path with query string)
  req.baseUrl; // '/admin'
  req.path; // '/new'
  req.baseUrl + req.path; // '/admin/new' (full path without query string)
});

var express = require('express')
var router = express.Router()

// middleware that is specific to this router
router.use(function timeLog (req, res, next) {

  next()
})
// define the home page route
router.get('/', function (req, res) {
  res.send('Birds home page')
