Mongoose allows you to easily select resources by ID from your MongoDB. This is an important aspect to creating an API.

Server.js

'use strict';var expres = require('express');var mongoose = require('mongoose');mongoose.connect('mongodb://localhost/simple');var cors = require("cors");var personSchema = {    firstName:String,    lastName:String,    email:String};//create a person model, and rename db as peoplevar Person = mongoose.model('Person', personSchema);var app = expres();app.use(cors());app.get('/people', function(request, response){    Person.find().select("firstName").exec(function(err, data) {        response.json(200, data);    })});app.get('/people/:id', function(request, response){    Person.findById(request.params.id, function(err, data) {       response.send(data);    });});app.listen(3000);

 

app.js:

/** * Created by Answer1215 on 12/9/2014. */'use strict';function MainCtrl(PeopleService) {    var vm = this;    vm.people = [];    vm.selectedPerson = {};        vm.getPeople = PeopleService.getPeople().then(function(response) {        vm.people = response.data;    });    vm.selectPerson = function(person) {        PeopleService.getSelectedPerson(person).then(function(response) {            vm.selectedPerson = response.data;            vm.selectedPerson.fullName = response.data.firstName + " " + response.data.lastName;        });    }}function PeopleService($http) {    var PeopleService = {};    PeopleService.getPeople = function() {         return $http.get('http://localhost:3000/people');    }    PeopleService.getSelectedPerson = function(person) {        return $http.get('http://localhost:3000/people/'+person._id);    }    return PeopleService;}angular.module('app',[])    .controller('MainCtrl', MainCtrl)    .service('PeopleService', PeopleService);
