如何调试Node.js

可以直接在vs code里面调试

在debug侧边栏里，创建一个launch.json，选择node.js。然后会自动生成

{

    // 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": "Launch Program",

            "skipFiles": [

                "<node_internals>/**"

            ],

            "program": "${workspaceFolder}\\index.js"

        }

    ]

}
