# Selecting language servers

If there are multiple installed, the highest priority will win. To select the server you want independent of priority you can do this:

(add-to-list 'lsp-disabled-clients 'ruby-ls) ;; solargraph
(add-to-list 'lsp-enabled-clients 'ruby-lsp-ls) ;; ruby-lsp (shopify's thing)

# Typescript

# Setup

# Ruby

There are a bunch of options for LSP servers. You can have multiple servers and the one used can be specified in a dir-local file See also emacs-lsp FAQ

# Vue2

Install vls

# Issues

When trying to start vls:

Error: Cannot find module 'vscode-css-languageservice/lib/umd/data/browsers'

# Performance

I had performance issues with LSP mode, especially with Typescript.

See https://emacs-lsp.github.io/lsp-mode/page/performance/ for suggestions.

I increased the read-process-output-max to 3mb and that seemed to help.

I was already using emacs v28, so I just rebuild it with native comp. There was some pain making the transition, but it completely solved the performance issues.

See https://xenodium.com/emacs-plus-with-native-comp/ and https://github.com/d12frosted/homebrew-emacs-plus#emacs-27-and-emacs-28-options
