Nothing Happening

Electron: 1.7.9 Nodejs: 9.2.0 OS: Windows 10

I have installed electron-log

npm install --save electron-log

I have included the module

var log = require('electron-log');

Yet upon attempting to log something

log.info('Hello, log - info'); log.warn('Hello, log - warning');

Absolutely nothing is happening. No errors are occuring, no log messages in console, and no file is being created where the documentation suggests it should be created:

%USERPROFILE%\AppData\Roaming\<app name>\log.log

Are you able to confirm this is working in node 9.2.0?

Okay so through some testing I’ve discovered few things – I will admit your documentation is a little misleading – but maybe thats just my interpretation of it. Posting the default behavior in the event this helps anyone else:

To use this in main.js, you must include as:

var log = require('electron-log');

Outside of main.js, include as such:

var log = require('electron-log/renderer');

By default, only .error and .warn will result in output to the local file.

log.error('this is an error');
log.warn('this is a warning');

To help showcase where each log level gets written by default, I used the following test block:

log.error('test');
log.warn('test');
log.info('test');
log.verbose('test');
log.debug('test');
log.silly('test');

If used within the main process:

main console: error, warn, info, verbose, debug, silly render console: -none- local file: error, warn

If used outside the main process:

main console: error, warn, info, verbose, debug, silly render console: error, warn, info, verbose local file: error, warn

You can disable logging to console, from the main process, as such:

log.transports.console.level = false;

However, if you attempt to disable console level logging within a render process, it breaks. If you wish to disable console level logging in a render process, you will need to include electron-log like this instead:

var electronRemote = require('electron').remote;
var log = electronRemote.require('electron-log');
log.transports.console.level = false;

Personally, I find it odd that logs within the render process, are also logged to the main process console. I also feel like your documentation could use some clarification.
