Nestjs: right settings for debugging

Bored to use a lot of console.log() in your Nestjs application?
Want to become more productive and a better coder debugging directly in VSCode to find out what's wrong in your stack trace?

First thing first:
open to VSCode settings, then go to Extensions and then Javascript Debugger.
Find out Auto Attach Filter section and select Always from the dropdown.

Then, create a launch.json file in the .vscode folder of your project, then copy/paste the following code:

{
    "version": "0.2.0",
    "configurations": [
      {
        "type": "node",
        "request": "launch",
        "name": "Debug Nest Framework",
        "runtimeExecutable": "npm",
        "runtimeArgs": [
          "run",
          "start:debug",
          "--",
          "--inspect-brk"
        ],
        "autoAttachChildProcesses": true,
        "restart": true,
        "sourceMaps": true,
        "stopOnEntry": false,
        "console": "integratedTerminal",
      }
    ]
}
Enter fullscreen mode Exit fullscreen mode

It enables debug and console.log() at the same time.

Be sure that in your package.json file there's the debug script:

"scripts": {
    ...
    "start:debug": "nest start --debug --watch",
    ...
}
Enter fullscreen mode Exit fullscreen mode

Now you're ready to debug your application!

Type yarn start:debug or npm run start:debug ...

Enjoy!

It's important mentioning that "yarn start:debug" or "npm run start:debug" must be run on VSCode terminal, once the Auto Attach Filter depends on it

Neat and Concise except "Find out Auto Attach Filter section and select Always from the dropdown."
It is worth mentioning that the option can be found in user settings(ctrl+shift+p)
