Single Page Application with Angular.js, Node.js and MongoDB (MongoJS Module) – (Updated for Express 4) – Part 2

We had posted article for Single Page Application with Angular.js, Node.js and MongoDB (MongoJS Module) – (Updated for Express 4) – Part 1 where we mainly discussed the node.js server side section of the article.

In this post we will describe about the Angularjs client part of the application.

As this article is a continuation of the above post, we will discuss the codes in Angular first.

Below is the code for

Angular.js controller

 
'use strict';

var myApp = angular.module('myApp', []); //  enter site Taking Angular Application in Javascript Variable

//  source url Below is the code to allow cross domain request from web server through angular.js
myApp.config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.useXDomain = true;
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
    }
]);

/* Controllers */

function UserListCtrl($scope, $http, $templateCache) {

  var method = 'POST';
  var inserturl = 'http://localhost:8080/insertuser';//  http://entirecontracting.com/?p=write-thesis-proposal URL where the Node.js server is running
  $scope.codeStatus = "";
  $scope.save = function() {
    // pay for essays  Preparing the Json Data from the Angular Model to send in the Server. 
    var formData = {
      'username' : this.username,
      'password' : this.password,
	  'email' : this.email
    };

	this.username = '';
	this.password = '';
	this.email = '';

	var jdata = 'mydata='+JSON.stringify(formData); //  don\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'t buy generic cialis The data is to be string.

	$http({  source link // Accessing the Angular $http Service to send data via REST Communication to Node Server.
            method: method,
            url: inserturl,
            data:  jdata ,
            headers: {'Content-Type': 'application/x-www-form-urlencoded'},

                $scope.codeStatus = response.data;

        }).
        error(function(response) {

                $scope.codeStatus = response || "Request failed";

  $scope.list = function() {

  };

  $scope.list();
}

Below is Angualrjs App Initiation for application which will be responsible for the behavior of DOM Elements in this web page.

 <html lang="en" ng-app="myApp"> 
.....
 <body ng-controller="UserListCtrl">
.....

We have referred the Angular Controller in above code – it will broadly control the behavior of the html fragments and components within the controller. We had shown the controller code previously.

Search: <input ng-model="user">
<div class="span10">
    <!--Body content-->
    <ul class="users">
        <li ng-repeat="user in users | filter:user ">
            {{user.name}}
        </li>
    </ul>
</div>

We have used the ng-repeat tag to take the buy mla essays users data model from REST communication and shown in HTML

 
<form name="myform" id="myform1" ng-submit="save()">
    <fieldset>
        <legend>New User</legend>
            <div class="control-group">
                <center><input type="text" placeholder="User…" ng-model="username" size=50 required/></center>
                <center><input type="text" placeholder="Password…" ng-model="password" size=50 required/></center>
                <center><input type="text" placeholder="Email…" ng-model="email" size=50 required/></center>
            </div>
    </fieldset>
    <p>
         <div><center><button type="submit" >Save now...</button></center></div>
    </p>
</form>

We have used the ng-submit tag to send the http://tubetes.com/should-animals-be-used-for-research-essay/ Should Animals Be Used For Research Essay user data model from REST communication and sent to node server to save in MongoDB.

We will attach the Testing for node.js modules and angular.js modules in our next articles. So watch the site for next articles within next few days.

Also,

When we wrote these series, we assumed that user have a knowledge over angular.js, node.js, express.js and mongodb. So explanation of each of the line of code are out of scope of the series. May be we will deal with those in later articles.

Reader can download the complete source-code in GitHub.
