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:
/**

*/
‘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);
