Electron Error: Requires constructor call

Question

While trying the electron using their Quick Start here. I encountered a weird problem. Searching on google yields no results.

following is my directory tree

.
├── index.html
├── main.js
├── node_modules
│   └── electron-prebuilt
└── package.json

contents of package.json

{
  "name": "desktop-widget",
  "version": "1.0.0",
  "main": "main.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "electron": "^0.4.1",
    "electron-prebuilt": "^0.36.7"
  },
  "devDependencies": {},
  "description": ""
}

contents of main.js

'use strict';

const electron      = require('electron');
const app           = electron.app;
const BrowserWindow = electron.BrowserWindow;

var mainWindow = null;

app.on('ready', function() {
    mainWindow = BrowserWindow({width: 800, height: 600});
    mainWindow.loadURL('file://', __dirname, 'index.html');

    mainWindow.on('closed', function() {
        mainWindow = null;
    })

});

on running the command node_modules/electron-prebuilt/dist/electron .
i get the following error:

Answer 1

That was real silly of me

I missed the new keyword. plus my loadURL function call is wrong (though i encountered it later and had nothing to do with the above error). In all, this final thing worked for me:

main.js

'use strict';

const electron      = require('electron');
const app           = electron.app;
const BrowserWindow = electron.BrowserWindow;

var mainWindow = null;

app.on('ready', function() {
    mainWindow = new BrowserWindow({width: 800, height: 600});
    mainWindow.loadURL('file://' + __dirname + '/index.html');

    mainWindow.on('closed', function() {
        mainWindow = null;
    })

});
