earn how to import data into your MongoDB and then use Express to serve a simple Node.js API.
Import data into MongoDB:
For exmaple, you have an data.json file and contains some data.
1. Start Mongod service:
//in the cmd
$ mongod
2. Open a new Tab, import the data:
mongoimport --db simple --collection people --jsonArray data.json
Import data.json file (a json array file), set database as simple, name it as people collection.

You can play around with those data:
// in cmd
$ mongo
Enter the mongodb cmd-clinet.
Find the data:
db.simple.find();
db.simple.findOne();
Remove data:
db.simple.remove()
Set up Server:
npm install -S express mongoose cors
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, ‘people‘);
var app = expres();
app.use(cors());
app.get(‘/people‘, function(request, response){
Person.find(function(err, data) {
response.json(200, data);
})
});
app.listen(3000);
app.js:
/**
* Created by Answer1215 on 12/9/2014.
*/
‘use strict‘;
function MainCtrl(PeopleService) {
var vm = this;
vm.people = [];
vm.getPeople = PeopleService.getPeople().then(function(response) {
vm.people = response.data;
});
}
function PeopleService($http) {
var PeopleService = {};
PeopleService.getPeople = function() {
return $http.get(‘http://localhost:3000/people‘);
}
return PeopleService;
}
angular.module(‘app‘,[])
.controller(‘MainCtrl‘, MainCtrl)
.service(‘PeopleService‘, PeopleService);
