Logger class

Singleton logger that writes all output to stderr.

Usage:

Logger.init(); // Call once at startup
Logger.info('Server started');
Logger.error('Something failed', error, stackTrace);

Configure via the LOG_LEVEL environment variable:

  • debug — verbose output for development
  • info — default; general operational messages
  • warn — potential issues that are non-fatal
  • error — failures that need attention
