neovim-plugin VS nvim-dap

Definitely remove it, as it is an anti-pattern that gained popularity because individuals often copy content without careful consideration. As far as I know, it primarily originated from this Github post, which was created during the early days of Lua's growing popularity in Neovim as an attempt to reinvent the wheel.

I'm pretty sure we got started down the .setup road because of this article by norcalli a few years ago. It was published when plugins started using Lua and suddenly I went from seeing one or two plugins using .setup to literally every single plugin use it.

Also, you can set up debugger integration with https://github.com/mfussenegger/nvim-dap .

You could use nvim-dap with nvim-dap-python.

I'd suggest starting with a Neovim distro that makes things work for you and as you get familiar you can transition to a more custom configuration as you see fit. If you want to do it by yourself then the most popular plugin for debugging in Neovim is nvim-dap and there is also an extension for Python to give you a more ready to go config instead of doing it yourself. You should read the docs of those 2 to see how you should customize accordingly your configuration.

(neovim only) nvim-dap

https://github.com/mfussenegger/nvim-dap + https://github.com/theHamsta/nvim-dap-virtual-text should be able to do it, I think?

If you want to debug types in TypeScript, you could use marilari88/twoslash-queries.nvim. If you would like to debug TypeScript/JavaScript code, then you need mfussenegger/nvim-dap, you could read this article: Debugging using DAP to understand how to set up it.

It's a feature I've added to nvim-dap that is pending review - https://github.com/mfussenegger/nvim-dap/pull/773
