Coming late, but it is worth the wait...

What's LSP

Please see my old post. Now LSP client is integrated in neovim to bring fast/smooth user experience!

What About LanguageClient-Neovim in That Post?

It's way hard to config and this one is no better than CoC.

What About CoC?

Wow, this one changes a lot since my last check. Now it's very easy to use and a lot mature. Strongly recommend to people just from Visual Studio. It's a lot heavy as it looks like. It's an ambitious migration of VS extensions plus many powerful features. Major language as JS is a plus. If nvim-lsp fails me, I'll convert to CoC for sure.

The reason to prefer nvim-lsp a bit is native support and performance, though right now, I have no evidence to show that. Another execuse is deoplete plugin doesn't work nicely with CoC and some of my plugins are with deoplete 😢.

Anyway, now I could evaluate both of them in different projects in work and probably update later.

Nvim-LSP Setup in 3 Min

If setting up CoC is in 1 min, then lsp takes just a bit longer. To preview nvim's native lsp with me:

  1. Be sure to have conda at hand (you should!). If not please follow this. Just install nvim nightly build:
conda install -c daizeng1984/label/nightly nvim

  1. Comment out your old complete plugins like CoC, LanguageClient-neovim etc.

  2. Install plugin nvim-lsp

  3. Add these lines to your config.vimrc:

lua <<EOF
require'nvim_lsp'.pyls.setup{}
require'nvim_lsp'.tsserver.setup{}
EOF
  1. Then install language servers you need, for example pyls you can do: conda install -y -c conda-forge python-language-server and for tsserver you can do in nvim directly :LspInstall tsserver. For more language support, look at here. Ideally, all these plugins should be installed with :LspInstall seamlessly in nvim in the future just like CoC.

Java

Java is missing here. But again, just a matter of time.

Autocomplete

If you need autocomplete, add autocomplete plugin e.g. deoplete-lsp.
