i want read text file in local directory,i found many examples have used httprequest()i don't want use of servers xampp,wampp etc

i using js!!

best partice php,nodejs or backend langaugae such things, in case might use angularjs .

add below in js

    var myapp = angular.module('myapp', []);  myapp.controller('mainctrl', function ($scope) {     $scope.showcontent = function($filecontent){         $scope.content = $filecontent;     };   });  myapp.directive('onreadfile', function ($parse) {     return {         restrict: 'a',         scope: false,         link: function(scope, element, attrs) {             var fn = $parse(attrs.onreadfile);              element.on('change', function(onchangeevent) {                 var reader = new filereader();                  reader.onload = function(onloadevent) {                     scope.$apply(function() {                         fn(scope, {$filecontent:onloadevent.target.result});                     });                 };                  reader.readastext((onchangeevent.srcelement || onchangeevent.target).files[0]);             });         }     }; }); 

the below html body:

<div ng-controller="mainctrl" class="container">   <h1>select text file</h1>     <input type="file" on-read-file="showcontent($filecontent)" />     <div ng-if="content">         <h2>file content is:</h2>         <pre>{{ content }}</pre>     </div> </div> 

keep in mind read, write , save function should done in back-end side.
