---@brief
---
-- https://github.com/vuejs/language-tools/tree/master/packages/language-server
--
-- Volar language server for Vue
--
-- Volar can be installed via npm:
-- ```sh
-- npm install -g @vue/language-server
-- ```
--
-- Volar by default supports Vue 3 projects.
-- For Vue 2 projects, [additional configuration](https://github.com/vuejs/language-tools/blob/master/extensions/vscode/README.md?plain=1#L19) are required.
--
-- **Hybrid Mode (by default)**
--
-- In this mode, the Vue Language Server exclusively manages the CSS/HTML sections.
-- You need the `ts_ls` server with the `@vue/typescript-plugin` plugin to support TypeScript in `.vue` files.
-- See `ts_ls` section for more information
--
-- **No Hybrid Mode**
--
-- Volar will run embedded `ts_ls` therefore there is no need to run it separately.
-- ```lua
-- local lspconfig = require('lspconfig')
--
-- lspconfig.volar.setup {
-- -- add filetypes for typescript, javascript and vue
-- filetypes = { 'typescript', 'javascript', 'javascriptreact', 'typescriptreact', 'vue' },
-- init_options = {
-- vue = {
-- -- disable hybrid mode
-- hybridMode = false,
-- },
-- },
-- }
-- -- you must remove ts_ls setup
-- -- lspconfig.ts_ls.setup {}
-- ```
--
-- **Overriding the default TypeScript Server used by Volar**
--
-- The default config looks for TypeScript in the local `node_modules`. This can lead to issues
-- e.g. when working on a [monorepo](https://monorepo.tools/). The alternatives are:
--
-- - use a global TypeScript Server installation
-- ```lua
-- require'lspconfig'.volar.setup {
-- init_options = {
-- typescript = {
-- -- replace with your global TypeScript library path
-- tsdk = '/path/to/node_modules/typescript/lib'
-- }
-- }
-- }
-- ```
--
-- - use a local server and fall back to a global TypeScript Server installation
-- ```lua
-- require'lspconfig'.volar.setup {
-- init_options = {
-- typescript = {
-- -- replace with your global TypeScript library path
-- tsdk = '/path/to/node_modules/typescript/lib'
-- }
-- },
-- on_new_config = function(new_config, new_root_dir)
-- local lib_path = vim.fs.find('node_modules/typescript/lib', { path = new_root_dir, upward = true })[1]
-- if lib_path then
-- new_config.init_options.typescript.tsdk = lib_path
-- end
-- end
-- }
-- ```
return {
cmd = { 'vue-language-server', '--stdio' },
filetypes = { 'vue' },
root_markers = { 'package.json' },
init_options = volar_init_options,
before_init = function(_, config)
if config.init_options and config.init_options.typescript and config.init_options.typescript.tsdk == '' then
config.init_options.typescript.tsdk = get_typescript_server_path(config.root_dir)
end
end,
}
