Pretty logger for Electron apps
By default, logs from the renderer process don't show up in the terminal. Now they do.
You can use this module directly in both the main and renderer process.
$ npm install electron-timber
Requires Electron 5 or later.
Main process:
const {app, BrowserWindow} = require('electron');
const logger = require('electron-timber');
let mainWindow;
(async () => {
await app.whenReady();
mainWindow = new BrowserWindow();
await mainWindow.loadURL(…);
logger.log('Main log');
logger.error('Main error');
const customLogger = logger.create({name: 'custom'});
customLogger.log('Custom log');
})();Renderer process:
const logger = require('electron-timber');
logger.log('Renderer log');
logger.error('Renderer error');Logging will be prefixed with either main or renderer depending on where it comes from.
Logs from the renderer process only show up if you have required electron-timber in the main process.
The methods are bound to the class instance, so you can do: const log = logger.log; log('Foo');.
Like console.log.
Like console.warn.
Like console.error.
Like console.time.
Like console.timeEnd.
Log each line in a stream.Readable. For example, child_process.spawn(…).stdout.
Same as streamLog, but logs using console.warn instead.
Same as streamLog, but logs using console.error instead.
Create a custom logger instance.
You should initialize this on module load so prefix padding is consistent with the other loggers.
Type: object
Type: string
Name of the logger. Used to prefix the log output. Don't use main or renderer.
Type RegExp
Ignore lines matching the given regex.
Type: string
Can be info (log everything), warn (log warnings and errors), or error (log errors only). Defaults to info during development and warn in production.
Gets the default options (across main and renderer processes).
Sets the default options (across main and renderer processes).
Type: object
Same as the options for create().
You can show the output of only a subset of the loggers using the environment variable TIMBER_LOGGERS. Here we show the output of the default renderer logger and a custom unicorn logger, but not the default main logger:
TIMBER_LOGGERS=renderer,unicorn electron .- electron-util - Useful utilities for developing Electron apps and modules
