如何在VSCode中调试NodeMon项目 [英] How to debug a nodemon project in VSCode
问题描述
我有一个NodeJs项目，我使用nodemon运行它，
我希望在调试模式下运行它来完成开发任务，但我无法这样做。
I have a NodeJs project and I run it using nodemon,
I wish to run it in debug mode for development tasks, but I am unable to do so.
我发现我需要在.vscode文件夹下的launch.json文件中添加正确的配置，
我有一个 app .js 文件，它是主应用程序文件。
然后该应用程序在节点版本4.6.2 和端口8080 。
通常情况下，我使用 npm run dev 命令运行应用程序。
I found that I'll need to add the right configuration to the launch.json file under .vscode folder,
I have a app.js file which is the main app file.
And the application runs on node version 4.6.2 and on Port 8080.
In usual case I run the App using npm run dev command.
以下是我的launch.json文件-

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "MyApp",
"program": "${workspaceFolder}/app.js",
"runtimeVersion": "4.6.2",
"protocol": "legacy",
"port": 8080
//"runtimeExecutable": "/home/user/.nvm/versions/node/v4.6.2/bin/node"
},
{
"type": "node",
"request": "launch",
"name": "nodemon",
"runtimeExecutable": "nodemon",
"program": "${workspaceRoot}/app.js",
"restart": true,
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen",
"runtimeVersion": "4.6.2",
"protocol": "legacy",
"port": 8080
},
{
"type": "node",
"request": "launch",
"name": "DEBUG",
"runtimeExecutable": "nodemon",
"program": "${workspaceFolder}/app.js",
"restart": true,
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen",
"runtimeVersion": "4.6.2",
"protocol": "legacy",
"port": 8080
}
]
}
package.json如下-
{
"name": "myapp",
"description": "myapp",
"version": "1.35.0",
"private": true,
"scripts": {
"dev": "nodemon app.js",

},

}
我在运行DEBUG和nodemon配置时启动了该应用程序，
但是代码并没有在我放在app.js文件上的断点处暂停。

package.json或任何其他要求的更改更正了启动配置-launch.json，这将有助于我为用例调试VSCode中的应用程序吗？
What changes are required in package.json, or any corrections in Launch configuration - launch.json, that would help me to debug the application in VSCode for my usecase?
推荐答案
更改程序包.json到
Change package.json to
"scripts": {
"dev": "node app.js",
"debug": "nodemon --inspect app.js"
}
-检查是否版本> = 6.3。 --legacy或--auto 对于较旧的版本
然后将launch.json转换为：
And launch.json to:
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Node: Nodemon",
"processId": "${command:PickProcess}",
"restart": true,
"protocol": "inspector"
}
]
重新启动标志是此处的关键。
the restart flag is the key here.
通过新的调试脚本启动应用程序
Start app via new debug script
npm运行调试
npm run debug
- 在调试视图中，选择 Node：Nodemon 配置，然后按play
或F5 - 选择从上方开始的过程
- In Debug view, select the Node: Nodemon configuration and press play or F5
- Choose the process started above
