remote-device-logger

A logging tool for a remote device equipped with no inspector to send a log to the receiver via WebSocket.

Install

$ npm i remote-device-logger --save-dev

Usage

Start the remote-device-logger cli on the server-side. This is the log receiver.

$ remote-device-logger -p 8080

Send logs from the client-side.

import RDL from 'remote-device-logger';

const logger = new RDL({
  element: document.body,
  webSocketUrl: `ws://${ location.hostname }:8080`,
});

// log() method sends and displays logs.
logger.log('Client launched');
logger.log('This log message is sent by Remote Device Logger');

// remote-device-logger catches errors, too.
throw new Error('Please catch this error');

You will find logs on the client-side and the same logs in the standard output on the server-side.
