configs VS nvim-lua-guide

So, I immediately went to configure my jsonls, using the awesome plugin like this but nothing, my autocompletion (nvim-cmp) won't show any useful info.

I am working on adding support for sign_define to my colorscheme as I just recently learned about LSP and have been adding that to my neovim setup and I feel that signs would just make it pop even more. I did some research on sign_define, reading the help text and looking at examples such as comestics.lua, but am running into one issue.

My best would be to have a json / scripting whatsover where I can program this, for example like this

this is my current zshrc

Instead, having a organized config tree like mine can help greatly when you need to change or tweak something.

Nvim Lua guide

My main struggles beyond a simple problem are just the inability to find a way to easily debug things and the general process for setting up a plugin. I mostly work with Python/Jupyter, some C and Lua/Bash scripts, and usually you can either write tests/print debug for smaller scale things or get some stack trace if you have an error. With Neovim development, it just feels like there's nothing more besides update plugin, try on neovim, fail, bash head against wall, and repeat, and that doesn't quite seem efficient or correct - I'm sure there's something out there that should make the process easier. I tried looking online but I haven't found many that really fit my needs (most of the resources here seem more targeted towards creating your own init.lua, and Luadev plugin's commands are all broken (:Luadev-RunLine and any other command keeps telling me I got some trailing space). I'm really just looking to see how to make a snippet library, but there doesn't seem to be much that helps me. If someone could let me know how they debug their plugin or point me to any external resources, please let me know!

I have no guidance for the first point. For the second, checkout the neovim lua guide or : lua-guide

A quick google search turned up this codeacademy class on learning to program in Javascript. I didn't vet the whole thing, but it appears to assume you know nothing, which is what you need. If you go through that, you can then consume one of the resources that /u/luascriptdev post to equate that back to Lua. Again, the concepts translate.
