---@brief
---
--- https://github.com/sveltejs/language-tools/tree/master/packages/language-server
---
--- Note: assuming that [ts_ls](#ts_ls) is setup, full JavaScript/TypeScript support (find references, rename, etc of symbols in Svelte files when working in JS/TS files) requires per-project installation and configuration of [typescript-svelte-plugin](https://github.com/sveltejs/language-tools/tree/master/packages/typescript-plugin#usage).
---
--- `svelte-language-server` can be installed via `npm`:
--- ```sh
--- npm install -g svelte-language-server
--- ```
---@type vim.lsp.Config
return {
cmd = { 'svelteserver', '--stdio' },
filetypes = { 'svelte' },
root_dir = function(bufnr, on_dir)
local fname = vim.api.nvim_buf_get_name(bufnr)
-- Svelte LSP only supports file:// schema. https://github.com/sveltejs/language-tools/issues/2777
if vim.uv.fs_stat(fname) ~= nil then
