The important bits are I use lsp-zero for my LSP (probably going to switch to native lsp because this causes segfaults for me sporadically) and I use nvim-dap to get a proper debugger experience.
I used to consider vs code a must for real dev work but this config has everything I considered important feature wise.
The only "home brewed" part is I wrote a lua plugin to look for a any env file specifications in .vscode/launch.json and load that file so the variables are available to the debugger which can also leverage these vs code files.
