---
--- Toolchain of the web. [Successor of Rome](https://biomejs.dev/blog/annoucing-biome).
---
--- ```sh
--- npm install [-g] @biomejs/biome
--- ```
---
--- ### Monorepo support
---
--- `biome` supports monorepos by default. It will automatically find the `biome.json` corresponding to the package you are working on, as described in the [documentation](https://biomejs.dev/guides/big-projects/#monorepo). This works without the need of spawning multiple instances of `biome`, saving memory.
local util = require 'lspconfig.util'
---@type vim.lsp.Config
return {
cmd = function(dispatchers, config)
local cmd = 'biome'
local local_cmd = (config or {}).root_dir and config.root_dir .. '/node_modules/.bin/biome'
if local_cmd and vim.fn.executable(local_cmd) == 1 then
cmd = local_cmd
end
return vim.lsp.rpc.start({ cmd, 'lsp-proxy' }, dispatchers)
end,
filetypes = {
'astro',
'css',
'graphql',
'html',
'javascript',
'javascriptreact',
'json',
'jsonc',
'svelte',
'typescript',
'typescript.tsx',
'typescriptreact',
'vue',
},
workspace_required = true,
root_dir = function(bufnr, on_dir)
-- The project root is where the LSP can be started from
-- As stated in the documentation above, this LSP supports monorepos and simple projects.
-- We select then from the project root, which is identified by the presence of a package
-- manager lock file.
local root_markers = { 'package-lock.json', 'yarn.lock', 'pnpm-lock.yaml', 'bun.lockb', 'bun.lock' }
-- Give the root markers equal priority by wrapping them in a table
root_markers = vim.fn.has('nvim-0.11.3') == 1 and { root_markers, { '.git' } }
or vim.list_extend(root_markers, { '.git' })
-- We fallback to the current working directory if no project root is found
local project_root = vim.fs.root(bufnr, root_markers) or vim.fn.getcwd()
-- We know that the buffer is using Biome if it has a config file
-- in its directory tree.
local filename = vim.api.nvim_buf_get_name(bufnr)
local biome_config_files = { 'biome.json', 'biome.jsonc' }
biome_config_files = util.insert_package_json(biome_config_files, 'biome', filename)
local is_buffer_using_biome = vim.fs.find(biome_config_files, {
