TelemetryCollector Api for developers

Minimal lightweight logging for Homey Apps

This module will be used in a Homey app to send logs to the TelemetryCollector App.

This module is implemented as a mixin pattern to simplify the use of the interface.

(For more information about mixins, see: > Useful Links > Mixins)

// Development
const inspector = require('node:inspector');

if (process.env.DEBUG === '1') {

    inspector.waitForDebugger();
  } catch (err) {
    inspector.open(9229, '0.0.0.0', true);

Migrations guide

Preferred

Rename the methods, it's fast (global search & replace), the code is more readable and the method calls the console message at the end anyway.

• this.log() > (renameTo) > this.logInfo()
• this.error() > (renameTo) > this.logError()
• this.debug() > (renameTo) > this.logDebug()
