function getCallerLine() {
  const err = new Error();
  const stack = err.stack || '';
  const callerLine = stack.split(/\n\s*at\s+/g);

  if (callerLine.length >= 2) {
    const str = callerLine[3];
    const [file, line, col] = str
      .replace(/^\s*at\s+/, '')
      .replace(/^(.*):(\d+):(\d+)$/, '$1|$2|$3')
      .split(/\|/g);

    const o = {
      toString: () => str,

      get str() {
        return str;
      },

      get file() {
        return file;
      },

      get line() {
        return parseInt(line);
      },

      get col() {
        return parseInt(col);
      },

      get error() {
        return err;
      },
    };

    return o;
  } else {
    return null;
  }
}

用法:

function foo() {
  console.info(getCallerLine());
}

foo(); // Prints this line as Caller Line details.

现在主机上有一个专门的功能:

console.trace()

在控制台以更易读的方式打印错误的堆栈跟踪:

console.log(ex, ex.stack.split("\n"));

结果示例:

[Error] [ 'Error',
  '    at repl:1:7',
  '    at REPLServer.self.eval (repl.js:110:21)',
  '    at Interface.<anonymous> (repl.js:239:12)',
  '    at Interface.EventEmitter.emit (events.js:95:17)',
  '    at Interface._onLine (readline.js:202:10)',
  '    at Interface._line (readline.js:531:8)',
  '    at Interface._ttyWrite (readline.js:760:14)',
  '    at ReadStream.onkeypress (readline.js:99:10)',
  '    at ReadStream.EventEmitter.emit (events.js:98:17)',
  '    at emitKey (readline.js:1095:12)' ]

任何Error对象都有一个堆栈成员，该成员捕获了构造它的点。

var stack = new Error().stack
console.log( stack )

或者更简单地说:

console.trace("Here I am!")

在v15.12.0中，有各种方法可以做到这一点，

1. console.trace(anything)
2. Error.captureStackTrace(Object)
3. console.log(new Error().stack)
4. Try Catch - Use console.log(e), where `e` is catched by catch block

或者更好地使用 在任何Javascript代码中的stacktracejs
