create routes node js express code example

Example 1: express get all routes and methods

function print (path, layer) {
  if (layer.route) {
    layer.route.stack.forEach(print.bind(null, path.concat(split(layer.route.path))))
  } else if (layer.name === 'router' && layer.handle.stack) {
    layer.handle.stack.forEach(print.bind(null, path.concat(split(layer.regexp))))
  } else if (layer.method) {
    console.log('%s /%s',
      layer.method.toUpperCase(),
      path.concat(split(layer.regexp)).filter(Boolean).join('/'))
  }
}

function split (thing) {
  if (typeof thing === 'string') {
    return thing.split('/')
  } else if (thing.fast_slash) {
    return ''
  } else {
    var match = thing.toString()
      .replace('\\/?', '')
      .replace('(?=\\/|$)', '$')
      .match(/^\/\^((?:\\[.*+?^${}()|[\]\\\/]|[^.*+?^${}()|[\]\\\/])*)\$\//)
    return match
      ? match[1].replace(/\\(.)/g, '$1').split('/')
      : '<complex:' + thing.toString() + '>'
  }
}

app._router.stack.forEach(print.bind(null, []))

Example 2: route parameter in node

var express = require('express');
var fs  = require('fs');
var app= express();
 app.get('/index/profile/:id',function(req,res){
    //  res.send('profile with id' + req.params.id)

    
    
 });
app.listen(3000,'127.0.0.1');
console.log('lsitng');
