Running nest.js from VS Code

Question

So, I'm playing around with this new framework http://nestjs.com/ who seems pretty awesome since it allows the usage of Typescript on Node, very likely to angular.

Using the starter https://github.com/kamilmysliwiec/nest-typescript-starter , I can run it with npm run start without any problem, but since there is a .vscode on the project, I assumed I could use VS Code to run and gain some debug abilities.

The problem is that when I run directly from VS Code, without changing anything in the code, I get the following problem:

Error: Cannot find module 'nest.js'

I tried to run from VS Code with and without it running from NPM, no success.

Thanks in advance.

I updated nest-typescript-starter today. The previous version had an old dist directory, with outdated imported packages. If you want to compile your application, use npm run start:prod script.

For those looking for a launch.json . There is one described at https://github.com/nestjs/nest/issues/776

{
    // Use IntelliSense to learn about possible attributes.

    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceFolder}\\src\\main.ts",
            "preLaunchTask": "tsc: build - tsconfig.json",
            "outFiles": [
                "${workspaceFolder}/dist/**/*.js"
            ]
        }
    ]
}

To debug with nestjs app. In 2020, after I follow first-step . In VS code change default setting from:

"version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": [
        "<node_internals>/**"
      ],
      "program": "${workspaceFolder}/start",
      "preLaunchTask": "tsc: build - tsconfig.json",
      "outFiles": [
        "${workspaceFolder}/dist/**/*.js"
      ]
    }
  ]

to this:

"version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": ["<node_internals>/**"],
      "program": "${workspaceFolder}/src/main.ts",
      "preLaunchTask": "tsc: build - tsconfig.json",
      "outFiles": ["${workspaceFolder}/dist/**/*.js"]
    }
  ]

And press F5 to debug. It works perfectly with me.
