javascript - Angularjs saving user input data and generate it to a json file -


i pretty new angularjs , web app development. i'm making simple web app. first, reads default settings json file. on web, users able change these settings. however, stuck on how save changes made users , how generate them new json file. don't know should put in controller. tried different methods found online none of them worked. please assist.

app.js - did read file part need save file part. 

var app1 = angular.module("myapp", [])     app1.controller("myappctrl", function ($scope, $http) {         $http.get('src/default.json').then(function(response){             $scope.messes = response.data;         });     });

logically should work server side processing in situation. write server api (in php, node.js, java etc) accept json, convert json file , stores somewhere , returns downloadable link of physical json file.

so in case:

$http.get('src/default.json').then(function(response){   $scope.messes = response.data;   // perform logic, create json , send server });

let server heavy lifting of processing. it's important consider size of json data may affect browser user experience badly.
