}Caution
lspconfig.luau_lsp.setup should NOT be called, it may cause conflicts with the plugin
require("luau-lsp").setup {

end,
}Roblox types are downloaded from the luau-lsp repository and passed to the language server.
require("luau-lsp").setup {
platform = {
type = "roblox",
},
types = {
roblox_security_level = "PluginSecurity",
},
}Sourcemap generation is done by running rojo sourcemap --watch default.project.json --output sourcemap.json.
require("luau-lsp").setup {
sourcemap = {
enabled = true,
autogenerate = true, -- automatic generation when the server is attached
rojo_project_file = "default.project.json",
sourcemap_file = "sourcemap.json",
},
}:LuauLsp regenerate_sourcemap {file} is provided to start sourcemap generation with the project file passed as argument (optional).
You can install the companion plugin here.
require("luau-lsp").setup {
plugin = {
enabled = true,
port = 3667,
},
}require("luau-lsp").setup {
types = {
definition_files = { "path/to/definitions/file" },
documentation_files = { "path/to/documentation/file" },
},
}require("luau-lsp").setup {
fflags = {
sync = true, -- sync currently enabled fflags with roblox's published fflags
override = {
LuauSolverV2 = "True", -- enable the new solver
},
},
}:LuauLsp bytecode and :LuauLsp compiler_remarks open a new window and show the current Luau file bytecode and compiler remarks. It will automatically update if you change the file or edit it. Close with q.

The server is not able to read .luaurc aliases yet, but require("luau-lsp").aliases() can read .luaurc if it exists and returns a table containing the aliases with @.
.luaurc lookup order:
.luaurclib/.luaurcsrc/.luaurc
require("luau-lsp").setup {
server = {
settings = {
["luau-lsp"] = {
require = {
directoryAliases = require("luau-lsp").aliases(),
},
},
},
},
}require("luau-lsp").setup {
server = {
settings = {

["luau-lsp"] = {
completion = {
imports = {

},
