How to upload files from Asp.Net MVC application to SharePoint 2013 with Angualr Js

I had an opportunity to work on an assignment related to upload of documents from Asp.Net MVC application into a SharePoint site with Angular Js.   Follow the the simple steps provided below to upload documents into SharePoint 2013 document library with Angular Js

Create a ASP.NET MVC Application and install jquery and Angular JS from Nuget.

Modify the Index.Cshtml(under View->Home) with the following code

 <table style="width:100%;">
     <tr>
         <td>
             <label for="lblinput">Input the search string</label>
         </td>
         <td>
             <input id="Text1″ type="text" ng-model="Search" value="Category" />
         </td>
     </tr>
     <tr>
         <td>
             <input id="Submit1″ type="submit" value="submit" ng-click="GetDetails()" />
         </td>
     </tr>
 </table>
 <table style="width:100%;">
     <tr>
         <td>
             <label for="lblinput">Add value to Sharepoint</label>
         </td>
         <td>
             <input id="Text1″ type="text" ng-model="NewItem" value="Category" />
         </td>
     </tr>
     <tr>
         <td>
             <input id="Submit1″ type="submit" value="submit" ng-click="Add()" />
         </td>
     </tr>
 </table>
 <table>
     <tr>
         Select File to Upload :
         <input id="inputFile" type="file" />
         <input type="button" ng-click="Upload();" value="Upload" />
     </tr>
 </table>
 <h1>{{title}}</h1> 
 {{station_list}}

Create a Script.js File and copy and paste the below code:

 var app = angular.module("myApp", []);
 //This is to get the data from sharepoint
 app.controller("myController", function($scope, $http, $q) {
             $scope.GetDetails = function() {
                     $http({
                             withCredentials: true,
                             method: 'GET',
                             headers: {"Accept": "application/json;odata = verbose"
                             },
                             url: "http://[SharePoint Site]/_api/lists/getbytitle('" + $scope.Search + "')/items"
                         })
                         .then(function(response) {
                             var station_list = [];
                             $.each(response.data.d.results, function(key, value) {

                             $scope.title = "Data From Sharepoint";
                         });
                 };
                 //To get the formdigestvalue, which is required to insert data to sharepoint
