Simple Console Logger - better suited for AWS CloudWatch

log.js

/* eslint-disable no-console */
function notJson(test) {
  return (test !== Object(test) || test instanceof Error);
}

function log(fn, ...args) {
  fn(...args.map(x => (notJson(x) ? x : JSON.stringify(x))));
}

const logger = {
  trace: (...args) => { log(console.log, 'TRACE', ...args); },
  debug: (...args) => { log(console.log, 'DEBUG', ...args); },
  log: (...args) => { log(console.log, 'INFO', ...args); },
  info: (...args) => { log(console.log, 'INFO', ...args); },
  warn: (...args) => { log(console.error, 'WARN', ...args); },
  error: (...args) => { log(console.error, 'ERROR', ...args); },
  fatal: (...args) => { log(console.error, 'FATAL', ...args); },
  setLevel: () => {},
};

module.exports = logger;
