PluginLogger

Async, variadic, device-aware logger utility for Homebridge plugins. Supports platform-wide and device-specific logging with filtering and Homebridge log integration.

Why Use PluginLogger?

Homebridge plugin developers often need to:

• Log messages at different levels (info, warn, error, debug, etc.)
• Filter logs for specific devices or contexts
• Support dynamic log modes (debug, standard, none) at runtime
• Avoid leaking secrets or sensitive data in logs
• Integrate seamlessly with Homebridge's logging system

PluginLogger solves these needs with:

• Device-aware logging:

  • Log messages for a specific device using logger.device(deviceId). This helps users and developers debug issues for individual accessories without cluttering the main log.
  • Device logs are only emitted if the device ID is enabled, reducing noise and improving focus during troubleshooting.

• Async, variadic log methods:

  • All log methods are async and accept any number of arguments, so you can log complex or dynamic data easily.
  • Async design allows for runtime log mode checks and future extensibility (e.g., remote log streaming).

• Dynamic log mode support:

  • Pass a getLoggingMode function to control log verbosity at runtime (e.g., 'debug', 'standard', 'none').
  • Enables plugins to respect user preferences or config changes without restart.

• Homebridge integration:

  • Works with the Homebridge log object, so logs appear in the UI and standard output as expected.
  • Supports Homebridge's custom log levels (e.g., success).

• Security and privacy:

  • Designed to avoid logging secrets or sensitive values.
  • Encourages best practices for log filtering and error handling.

Features

• Info, success, warn, error, and debug log levels
• Device-specific logging with filtering
• Async, variadic log methods
• Dynamic runtime log mode switching
• Designed for Homebridge plugins (but reusable elsewhere)

Usage

import { PluginLogger } from './PluginLogger.js';
const logger = new PluginLogger(homebridgeLog, { getLoggingMode, enabledDeviceIds: ['ABC123'] });
await logger.info('Platform log');
await logger.device('ABC123').info('Device log');

API

• info, success, warn, error, debug (async, variadic)
• device(deviceId) returns a logger instance for that device
• Device logs are only emitted if the device ID is enabled
• All log methods respect the current logging mode
