vim-blueplanet VS nvim-dap

To my knowledge vim-test has no out-of-the-box configuration for TypeScript. I forgot why. Anyway here is my configuration that adds mocha and jest as testers for TypeScript. Though it is mostly based on the existing JavaScript support of vim-test it adds some extra support for Vue testing and project local binaries. Finally ensure you enabled these testers in the vim-test configuration (g:test#custom_runners).

You could take a look here at my configuration. Not sure if that is helpful. You should first read up native packages as it has been linked above. I don't explain the little sneaks and features here. But in its core I put file and directory structure above everything else. I barely import anything manually but fully rely on automated mechanisms. I use lazy loading heavily. I use a mix of .vim and .lua files depending on its content and which language is easier (e.g. mappings are simpler in VimL. In result I have hundreds of files in my configuration. My everything follows a structure. With tools like fzf or telescope it is too easy to open the file you search for. It's basically no overhead. It would be more work to find what I search for if I would have less files. Finally this keeps everything incredibly independent. I can add, change and especially remove thing very easily as most things are very separated and independent. I want to remove a plugin, all its config, mappings, highlights, signs, ... I just remove one directory. Nothing more and nothing less. Clean cut. If I want a plugin and everything around it (copy-paste from above) to be lazy loaded it just works out-of-the-box. It's very simple and elegant. In my opinion. Though you can easily dislike it if you don't agree that strong with the approach it's fundamental arguments.

There are DAP extensions for both Vim (e.g. https://github.com/puremourning/vimspector) and NeoVim (https://github.com/mfussenegger/nvim-dap). I can't speak as to the experience in detail (I think I briefly played with nvim-dap a year or two ago), but I suspect that for most it will be good enough.

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.
