coc-snippets VS cmp-nvim-ultisnips

For coc, there's coc-snippets

I'm using coc-snippets. https://github.com/neoclide/coc-snippets Is there a way to better organise the snippets file? I need a better way to keep track of what snippets have been added already. Can I break up the snippets file into smaller files like you do with includes in PHP or imports with scss files? I rely on the snippets a lot and Im constantly adding to my snippets files for scss, php and js.

If you don't want to setup a bunch of customizations and just want it to work then coc.nvim is the way to go, just install coc.nvim and coc-r-lsp extenstion. For snippets get coc-snippets extension, which will use ultisnips for snippets.

I didn't know lsp-zero, but this integration seems just for me except for that I am using UltiSnips instead of luasnip. Just curious how difficult do you think it is to add UltiSnips integration along with cmp-nvim-ultisnips?

For cmp you will need the autocompletion engine and the sources to use. Sources are plugins for cmp that will populate the popup menu with items from different contexts, like from nvim-lsp, ultisnips, vsnip, etc. So you will need to install nvim-cmp along with sources like nvim-lsp source and ultisnips source. Finally, you will need the setup() function to add the expansion trigger, list the sources, add mappings, etc. You will just have to read the docs on the README in the repo for some example code. Unfortunately, those examples are not great to copy/paste if you have no clue what it's doing.
