Menu
I have installed electron-modules package for implementing tabs in electron as shown below
package.json
{
"name": "Backoffice",
"version": "1.0.0",
"description": "BackOffice application",
"main": "main.js",
"scripts": {
"start": "electron ."
},
"author": "Karthik",
"license": "ISC",
"devDependencies": {
"electron": "^2.0.8",
"electron-tabs": "^0.9.4"
}
}
main.js
const electron = require("electron");
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
const Menu = electron.Menu;
const path = require("path");
const url = require("url");
const TabGroup = require("electron-tabs");
let win;
const tabGroup = new TabGroup();
function createWindow() {
win = new BrowserWindow();
win.loadURL(url.format({
pathname:path.join(__dirname,'index.html'),
protocol:'file',
slashes:true
}));
win.on('closed',()=>{
win = null;
})
}
app.on('ready', function(){
createWindow();
const template = [
{
label : 'Backoffice',
submenu: [
{
label : 'Account Management',
click : function () {
let tab = tabGroup.addTab({
title: "Electron",
src: "http://electron.atom.io",
visible: true
});
}
},
{
label : 'HR Management',
click : function () {
console.log("CLICK HM menu");
}
},
]
}
]
const menu = Menu.buildFromTemplate(template);
Menu.setApplicationMenu(menu);
});

I am getting the following error when I run npm start
App threw an error during loadReferenceError: document is not defined at Object.<anonymous> (C:\workspace\nodejs_workspace\electron\menu-demo\node_modules\electron-tabs\index.js:3:1)

Why am I not able to load electron-modules package.
What is causing this error? How to create a new tab on click on application menu in electron?

As @coolreader18 explained in details, you have to use electron-tabs in Renderer process
This means you have to notify the html from main.js when you click a menu item. MenuItem's click provides you the caller BrowserWindow so you can send message to it.
main.js
...
{
label: 'Account Management',
click: function (menuItem, browserWindow, event) {
browserWindow.webContents.send('add-tab', {
title: 'Electron',
src: 'http://electron.atom.io',
visible: true
})
}
},
...
index.html
<body>
...
<script>
const { ipcRenderer } = require('electron')
const TabGroup = require('electron-tabs')
const tabGroup = new TabGroup()
ipcRenderer.on('add-tab', (event, arg) => {
tabGroup.addTab(arg)
})
</script>
</body>
