Broadcasting events from main process to all renderer process electron

I know how to send events from renderer process to main process using ipcRenderer.send() and ipcMain.on(). I could also send reply back to renderer process using event.sender.send() but got stuck on how can I send events from main process to all renderer process, more like a broadcast.

You can create array of references to BrowserWindow instances and when global event is necessary you can map it with sender function, like this for example:

let windows = [];

let backgroundComputation = new BrowserWindow(options);
let webInteractions = new BrowserWindow(different_options);
let imageProcessing = new BrowserWindow(another_options);

windows.push(backgroundComputation)
windows.push(webInteractions)
windows.push(imageProcessing)

let sender = (message, windows) => 
        windows.map((ref) => ref.webContents.send('event_name', message))

This will probably be handy if you have whole bunch of them. You can also set flag in options alwaysOnTop:true to true for window on top so any other window will stay underneath. Hope this helps!
