Logger interface

interface Logger {
  debug(message?: any): void;
  info(message?: any): void;
  warn(message?: any): void;
  error(message?: any): void;
}

This generic interface for loggers supports logging a string at one of four different levels (debug, info, warn, error). It's designed to be compatible with Node's console as well as commonly used logging packages and is tested against a few of them. Below are the logging libraries we test for compatibility against.

bunyan

const logger = bunyan.createLogger();

log4js

const logger = log4js.getLogger();

loglevel

const logger = loglevel.getLogger();

winston

const logger = winston.createLogger();
