---@brief
---
--- https://github.com/typescript-language-server/typescript-language-server
---
--- `ts_ls`, aka `typescript-language-server`, is a Language Server Protocol implementation for TypeScript wrapping `tsserver`. Note that `ts_ls` is not `tsserver`.
---
--- `typescript-language-server` depends on `typescript`. Both packages can be installed via `npm`:
--- ```sh
--- npm install -g typescript typescript-language-server
--- ```
---
--- To configure typescript language server, add a
--- [`tsconfig.json`](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) or
--- [`jsconfig.json`](https://code.visualstudio.com/docs/languages/jsconfig) to the root of your
--- project.
---
--- Here's an example that disables type checking in JavaScript files.
---
--- ```json
--- {
--- "compilerOptions": {
--- "module": "commonjs",
--- "target": "es6",
--- "checkJs": false
--- },
--- "exclude": [
--- "node_modules"
--- ]
--- }
--- ```
---
--- Use the `:LspTypescriptSourceAction` command to see "whole file" ("source") code-actions such as:
--- - organize imports
--- - remove unused code
---
--- ### Vue support
---
--- As of 2.0.0, the Vue language server no longer supports TypeScript itself. Instead, a plugin
--- adds Vue support to this language server.
---
--- *IMPORTANT*: It is crucial to ensure that `@vue/typescript-plugin` and `@vue/language-server `are of identical versions.
---
--- ```lua
--- vim.lsp.config('ts_ls', {
--- init_options = {
--- plugins = {
--- {
--- name = "@vue/typescript-plugin",
--- location = "/usr/local/lib/node_modules/@vue/typescript-plugin",
--- languages = {"javascript", "typescript", "vue"},
--- },
--- },
--- },
--- filetypes = {
--- "javascript",
--- "typescript",
--- "vue",
--- },
--- })
---
--- -- You must make sure the Vue language server is setup
--- -- e.g. vim.lsp.config('vue_ls')
--- -- See vue_ls's section for more information
--- ```
---
--- `location` MUST be defined. If the plugin is installed in `node_modules`,
--- `location` can have any value.
---
--- `languages` must include `vue` even if it is listed in `filetypes`.
---
--- `filetypes` is extended here to include Vue SFC.
return {
init_options = { hostInfo = 'neovim' },
cmd = { 'typescript-language-server', '--stdio' },
filetypes = {
'javascript',
'javascriptreact',
'javascript.jsx',
'typescript',
'typescriptreact',
'typescript.tsx',
},
root_markers = { 'tsconfig.json', 'jsconfig.json', 'package.json', '.git' },
handlers = {
-- handle rename request for certain code actions like extracting functions / types
['_typescript.rename'] = function(_, result, ctx)
local client = assert(vim.lsp.get_client_by_id(ctx.client_id))
vim.lsp.util.show_document({
uri = result.textDocument.uri,
range = {
start = result.position,
['end'] = result.position,
},
}, client.offset_encoding)
vim.lsp.buf.rename()
return vim.NIL
end,
},
on_attach = function(client, bufnr)
-- ts_ls provides `source.*` code actions that apply to the whole file. These only appear in
-- `vim.lsp.buf.code_action()` if specified in `context.only`.
vim.api.nvim_buf_create_user_command(bufnr, 'LspTypescriptSourceAction', function()
local source_actions = vim.tbl_filter(function(action)
return vim.startswith(action, 'source.')
end, client.server_capabilities.codeActionProvider.codeActionKinds)
vim.lsp.buf.code_action({
context = {
only = source_actions,
},
})
end, {})
end,
}
