Answer 2

你可以用日志记录库Winston或者自定义一个

function logWithLocation(...args) {
  const stackTrace = new Error().stack;
  const location = stackTrace.split('\n')[2].trim();
  const fileNameAndLineNumber = location
    .substring(location.lastIndexOf('/') + 1, location.lastIndexOf(':'))
    .replace('.js', '');
  console.log(`[${fileNameAndLineNumber}]`, ...args);
}


logWithLocation('Hello, World!');
