Reference

Logger `Interface`

Describes a common interface for logging.

interface Logger {
  trace(msg: any, ...args: unknown[]): any;

  debug(msg: any, ...args: unknown[]): any;

  info(msg: any, ...args: unknown[]): any;

  warn(msg: any, ...args: unknown[]): any;

  error(msg: any, ...args: unknown[]): any;
}

The interface offers various methods for logging messages at different levels of severity:

trace: Log a message at the TRACE level.
debug: Log a message at the DEBUG level.
info: Log a message at the INFO level.
warn: Log a message at the WARN level.
error: Log a message at the ERROR level.

Each method takes the message, usually a string, as the first argument and allows additional arguments for providing context (variables, objects, etc.).

Usage notes

Here's an example demonstrating how to use the Logger interface:

class MyLogger implements Logger {}

const logger = new MyLogger();

logger.info('Starting service processing...');

try {
  // ... service logic
} catch (error) {
  logger.error('An error occurred:', error);
}

logger.info('Service processing completed.');
