I wanted to share a simple approach to unify logging across module components that I found incredibly useful during development. This will put all* logging in a browser console and remove the need to monitor pm2/pi console logs.

In your main module code (MMM-ABC.js), where you define your sockets simply add:

if (notification === 'HELPER_MESSAGE') { if (this.config.debug === 1) { Log.info(payload); } //Receive a message, log the payload to the browser console. }

In your node_helper.js module, construct and send messages:

if (self.config.debug === 1) { apiMessage = moment().format('YYYY-MM-DD>>HH:mm:ss.SSSZZ') + ' [node_helper] << your log message content here >>'; self.sendSocketNotification('HELPER_MESSAGE', apiMessage); }

Hope this helps on your development journey!

*any code errors / exceptions will still throw to the raspberry pi console / pm2

@strawberry-3.141 - thank you for the approach. This is working out beautifully.

@E3V3A that worked perfectly. Thank you for sharing!

It did not display properly in Safari on my iPad Pro but it worked fine on my iPhone 6 Plus. So I tested it on other iPad models (my brother’s iPad Mini 4 and my friend’s iPad Air 2), everything was just fine. So I guessed this was because of the out-of-date iOS version of my iPad Pro since they had installed the latest iOS. And my guess was right.
