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!")

现在主机上有一个专门的功能:

console.trace()

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!")

如果有人还在寻找这个像我一样，那么有一个模块，我们可以使用称为“堆栈跟踪”。它真的很受欢迎。NPM链接

然后穿过痕迹。

  var stackTrace = require('stack-trace');
  .
  .
  .
  var trace = stackTrace.get();
  trace.map(function (item){ 
    console.log(new Date().toUTCString() + ' : ' +  item.toString() );  
  });

或者只是简单地打印跟踪:

var stackTrace = require('stack-trace');
.
.
.
var trace = stackTrace.get();
trace.toString();

如果你只想记录错误的堆栈跟踪(而不是错误消息)，Node 6及以上会自动在堆栈跟踪中包含错误名称和消息，如果你想做一些自定义错误处理，这有点烦人:

console.log (error.stack.replace(错误。信息,”)

这个解决方案将只记录错误名称和堆栈跟踪(因此，例如，您可以格式化错误消息，并在代码中的其他地方以您希望的方式显示它)。

上面的例子只打印错误名称，后面跟着堆栈跟踪，例如:

Error:

而不是:

Error: Error: Command failed: sh ./commands/getBranchCommitCount.sh HEAD

Did you mean this?
        rev-list

获取函数调用者详细信息:

/**
 * @typedef {Object} TCallerInfo
 * @property {() => string} toString
 * @property {string} str Caller error stack line.
 * @property {string} file Caller file path.
 * @property {number} line Caller line.
 * @property {number} col Caller column.
 * @property {Error} error Caller error stack instance.
 */

/**
 * @returns {TCallerInfo | null}
 */
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.
