如何在Visual Studio代码中调试异步/等待? [英] How to debug async/await in visual studio code?

问题描述

我想在Visual Studio代码中调试包含async/await的js文件，但它提醒我vscode不支持它.如何使vscode支持异步/等待?

I want to debug js file that includes async/await in visual studio code,but it reminds me that vscode doesn't support it. What can I do to make vscode support async/await?

推荐答案

到目前为止，在2019年，最新的VSCode支持异步/等待调试，只是想共享解决方案以防止vscode进入"(通过f11)进入在调试nodejs应用程序期间通过" async_hooks.js "和" inspector_async_hook.js "文件实现async/await方法.

As now, in 2019, latest VSCode supporting async/await debug, just would like to share solution to prevent vscode to "Step into" (by f11) into async/await method through the "async_hooks.js" and "inspector_async_hook.js" files during debug nodejs applications.

方法:

1)在vscode中按ctrl + p并输入> launch"，选择打开launch.json"

1) press ctrl+p in vscode and type ">launch", select "open launch.json"

2)打开"launch.json"后，只需将其添加到配置部分:

2) after opening "launch.json", just add to configuration section :

"skipFiles": [
    "inspector_async_hook.js",
    "async_hooks.js"
  ]

或更通用的版本:

"skipFiles": ["<node_internals>/**"]

所以最终的json应该看起来像这里:

So you final json should looks something like here:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "program": "${workspaceFolder}\\index.js",
      "skipFiles": ["<node_internals>/**"]
    }
  ]
}

在这些步骤之后，您可以在调试模式下按F11键后看到真正的异步方法.

After these steps you can see your real async method after pressing F11 in debug mode.
