Error In background Process

[akshaygarg834]

Console.log in background process not working. You can't see a single output out of it. How to debug it? Is there a way to change stdout of this bakground process to main process stdout so that all console.log() of background process start show in main process console.

You can use IPC to send a message to the main process to log messages to it, e.g. via:

Background window

const electron = require('electron');
const ipcRenderer = electron.ipcRenderer;

let log = function(message) {
    ipcRenderer.send('worker-message', message);
};

log('Hello world');

Main process

ipcMain.on('worker-message', (e, message) => console.log(message));

You could also pipe it to the developer tools console of the main window via:

Main process

ipcMain.on('worker-message', function(e, message) {
    mainWindow.webContents.send('worker-message', message);
});

Main window

const electron = require('electron');
const ipcRenderer = electron.ipcRenderer;
ipcRenderer.on('worker-message', (event, message) => console.log(message));

You can also see this stack overflow topic for ways to write to stdout in the main process.
