[MEAN Stack] First API -- 3. Select by ID with Mongoose and Express

 

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);
