全局的未捕获异常

REPL 使用 domain 模块来捕获该 REPL 会话的所有未捕获的异常。

在 REPL 中使用 domain 模块有这些副作用：

• 未捕获的异常仅在独立 REPL 中触发 'uncaughtException' 事件。 在另一个 Node.js 程序的 REPL 中为此事件添加监听器会导致 ERR_INVALID_REPL_INPUT。

  const r = repl.start();
  
  r.write('process.on("uncaughtException", () => console.log("Foobar"));\n');
  // 输出流包括：
  //   TypeError [ERR_INVALID_REPL_INPUT]: Listeners for `uncaughtException`
  //   cannot be used in the REPL
  
  r.close();

• 尝试使用 process.setUncaughtExceptionCaptureCallback() 会抛出 ERR_DOMAIN_CANNOT_SET_UNCAUGHT_EXCEPTION_CAPTURE 错误。

The REPL uses the domain module to catch all uncaught exceptions for that REPL session.

This use of the domain module in the REPL has these side effects:

• Uncaught exceptions only emit the 'uncaughtException' event in the standalone REPL. Adding a listener for this event in a REPL within another Node.js program results in ERR_INVALID_REPL_INPUT.

  const r = repl.start();
  
  r.write('process.on("uncaughtException", () => console.log("Foobar"));\n');
  // Output stream includes:
  //   TypeError [ERR_INVALID_REPL_INPUT]: Listeners for `uncaughtException`
  //   cannot be used in the REPL
  
  r.close();

• Trying to use process.setUncaughtExceptionCaptureCallback() throws an ERR_DOMAIN_CANNOT_SET_UNCAUGHT_EXCEPTION_CAPTURE error.
