Read Local File using XMLHttpRequest


I am trying to read in a local .json file located at C:/folder/blah.json

loadJSON('file:///C:/folder/blah.json', function (response) {
    jsonObject = JSON.parse(response);
    //Do stuff with it


function loadJSON(fileName, callback) {

var xobj = new XMLHttpRequest();
xobj.overrideMimeType("application/json");'GET', fileName, true);
xobj.onreadystatechange = function () {
    if (xobj.readyState == 4 && xobj.status == "200") {
        // Required use of an anonymous callback as .open will NOT return a value but simply returns undefined in asynchronous mode

When xobj.send(null) is called the .onreadystatechange doesn’t get called, nothing happens after the .send().
It should call the .onreadystatechange and then call my callback function where I can do what I need. It works in chrome but for some reason it doesn’t work in electron.

Anyhelp? Maybe there is a way I could use this


Unless you’ve disabled Node integration you can use require to load JSON files:

jsonObject = require('file:///C:/folder/blah.json')


I think XMLHttpRequests are not allowed filesystem access. You can use require or the fs module to read files from the filesystem.
