如何使VSCode运行“ npm start”之类的节点应用程序？

Question

I have a node app with the package.json like so:

{
    "name": "myexpressapp",   
    "version": "0.0.99",   
    "scripts": {
    "start": "node ./bin/www"   },  
    //etc
}

and in app.js I have

console.log ("Running version: "+process.env.npm_package_version);

When I run npm start in the command prompt this logs

Running version: 0.0.99

When I start (press F5 ) in VS Code this logs

Running version: undefined

What change do I need to make to launch.json to start the app in VS Code as if I had entered npm start in the command prompt?

Answer 1

I can now get it to run (but not debug) using the following launch.json :

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch via NPM#3",
            "runtimeExecutable": "npm",
            "windows": {
                "runtimeExecutable": "npm.cmd"
            },
            "runtimeArgs": [

                "start"
            ],
            "port": 5858,
            "cwd": "${workspaceRoot}"
        },
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program#1",
            "program": "app.js",
            "cwd": "${workspaceRoot}"
        }

    ]
}
