    Sure. https://codevisualstudio.com/docs/nodejs/nodejs-debugging

  • You can take a look at Microsoft’s Visual Studio IDE, it features a built-in Debugger that allows you to pause execution and test live variables. Following links: Presentation of VS Code https://www.youtube.com/watch?v=119e0lgol0s Download: https://code.visualstudio.com/

  • See in this link how to configure Vscode to use the debug of Nodejs applications. Configure Debug Vscode

There are some options for you to do this...

I think it’s cool to use vs code with extensions...
