Tips for running batch files prior to debugging in VS Code

Currently, I am working on a project using Typescript, nodeJS, and VS Code.

When it comes to debugging in VS Code, I have set up configurations in my launch.json file.

{
        "type": "node",
            "request": "launch",
            "name": "Launch via NPM",
            "runtimeExecutable": "npm",
            "runtimeArgs": [
                "run-script",
                "debug"
            ],
            "port": 9229
    },

I am wondering if there is a way to run a batch file before starting the service. In a regular console, I would normally do this by running:

env.cmd
    npm start

If you want to ensure a specific task is completed before debugging, consider adding it as a "preLaunchTask" with a unique identifier in your launch.json file. This task can be of the "shell type", allowing it to run as a shell command.

For example, a custom build:test task in your launch.json:

 {
    "type": "npm",
    "script": "build:test",
    "identifier": "buildtest",
    "group": {
        "kind": "test",
        "isDefault": true
    }
}

Then define the related debug task:

{
    "type": "node",
    "request": "launch",
    "name": "Mocha Tests",
    "preLaunchTask": "buildtest",
    "program": "${workspaceFolder}/node_modules/mocha/bin/_mocha",
    "args": [
        "-u",
        "tdd",
        "--timeout",
        "999999",
        "--colors",
        "${workspaceFolder}/temp/test/index.js"
    ],
    "internalConsoleOptions": "openOnSessionStart"
}
