Getting a list of routes from an Express 4 application

gistfile1.js

var _ = require('lodash')

var routes = _.map(_.filter(app._router.stack, function(item){    
  return (item.route != undefined)
}), function(route){  
  return {
    path: route.route.path,
    method: Object.keys(route.route.methods)[0]
  }
})

/**
Sample output:
{ route : '/', method: 'get' },
{ route : '/things', method: 'get' },
{ route : '/things', method: 'post' },
{ route : '/things/:id', method: 'get' },
...etc
**/

_.each(routes, function(route){
  console.log(route.method.toUpperCase() + '\t' + route.path)
})

/** 
Sample output:
GET   /
GET   /things
POST  /things
GET   /things/:id
...etc...
