[英]Accessing javascript variables from the vscode debug console (with node.js running)
[英]How to debug in VSCode for javascript running 'node'
我正在使用“node myscript.js”运行我的 JS。
我尝试在 VSCode 中使用“运行->开始调试”进行调试
我在 VSCode 中创建了一个工作区,当我看到它时创建了一个 launch.js
{
// 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": "pwa-chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}"
}
]
}
但是调试器失败了
Debugger listening on ws://127.0.0.1:55596/0b6425a4-e21c-47c2-a81d-bb8e43386246
For help, see: https://nodejs.org/en/docs/inspector
Debugger attached.
Waiting for the debugger to disconnect...
Process exited with code 0
我怎样才能让它工作?
我已经尝试了所有这些配置。 但是它们都没有达到我设置的断点。 我确实在终端的 Console.log 中看到了控制台 output。

"version": "0.2.0",
"configurations": [
{
"name": "Attach by Process ID",
"processId": "${command:PickProcess}",
"request": "attach",
"skipFiles": [
"<node_internals>/**"
],
"type": "pwa-node"
},
{
"name": "Launch via NPM",
"request": "launch",
"runtimeArgs": [
"run-script",
"debug"
],
"runtimeExecutable": "npm",
"skipFiles": [
"<node_internals>/**"
],
"type": "pwa-node"
},
{
"command": "npm start",
"name": "Run npm start",
"request": "launch",
"type": "node-terminal"
},
{
"type": "pwa-chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}"
}
]
使用pwa-chrome
类型启动将尝试在 web 浏览器中启动您的代码并运行它,这根本不运行node
,因此似乎是满足您需求的错误方法,并且以这种方式达到断点更复杂。 我建议使用简单的pwa-node
类型的启动来代替,因为打断点既好又容易。
第一步是通读 vscode 的节点调试说明: https://code.visualstudio.com/docs/nodejs/nodejs-debugging
在上面的说明中,它建议使用启动类型node
,但最近的说明建议使用pwa-node
(请参阅此处: VSCode 上的 pwa-node 类型启动配置是什么? )。
一个简单的.vscode/launch.json
文件,用于调试通过index.js
启动的节点应用程序:
{
"version": "0.2.0",
"configurations": [
{
"type": "pwa-node",
"request": "launch",
"name": "Launch my Node programme",
"skipFiles": ["<node_internals>/**"],
"cwd": "${workspaceFolder}",
"program": "index.js",
"args": [
"command-line-arguments",
"go-here",
]
}
]
}
一旦你有了启动器,你可以在你的 js 中设置一个断点,然后点击调试按钮。
