Answer 1

按F5键，选择节点，将launch.json文件替换为：

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug Nest Framework",
            "args": ["${workspaceFolder}/src/main.ts"],
            "runtimeArgs": ["--nolazy", "-r", "ts-node/register"],
            "sourceMaps": true,
            "cwd": "${workspaceRoot}",
            "protocol": "inspector"
        }
    ]
}

因此，设置一个断点并再次点击F5。

Answer 2

如果您使用的是nestjs 6.8+ (参见here)

在包含此内容的.vscode文件夹中添加launch.json

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "attach",
      "name": "Attach NestJS WS",
      "port": 9229,
      "restart": true,
      "stopOnEntry": false,
      "protocol": "inspector",
      "skipFiles": [
         "<node_internals>/**/*.js",
         "${workspaceRoot}/node_modules/**/*.js",
       ]
    }
  ]
}

然后运行npn run start:debug

然后在vscode中选择Attach NestJs Ws

完成了！您可以设置断点
