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 people

var 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);
