ARCHIVAL NOTICE

Please check out typescript.nvim, a minimal typescript-language-server integration plugin written in TypeScript.

You are free to use nvim-lsp-ts-utils in its current state (or copy the functionality you need into your Neovim config) but it will no longer receive updates or bug fixes.

nvim-lsp-ts-utils

Utilities to improve the TypeScript development experience for Neovim's built-in LSP client.

Requirements

Neovim 0.6.0+
nvim-lspconfig, which you are (probably) already using to configure typescript-language-server
plenary.nvim

Features

Organize imports (exposed as :TSLspOrganize)

Async by default. A sync variant is available and exposed as :TSLspOrganizeSync (useful for running on save).
Rename file and update imports (exposed as :TSLspRenameFile)

Enter a new path (based on the current file's path) and watch the magic happen.
Import all missing imports (exposed as :TSLspImportAll)

Gets all code actions, then matches against the action's title to determine whether it's an import action. Also organizes imports afterwards to merge imports from the same source.

Note: :TSLspImportAll depends on tsserver diagnostics, meaning that the function won't work for JavaScript files unless you set "checkJs": true inside tsconfig.json / jsconfig.json.

By default, the command will resolve conflicting imports by checking other imports in the same file and other open buffers. In Git repositories, it will check project files to improve accuracy. You can alter the weight given to each factor by modifying import_all_priorities (see below). This feature has a minimal performance impact, but you can disable it entirely by setting import_all_priorities to nil.

:TSLspImportAll will also scan the content of other open buffers to resolve import priority, limited by import_all_scan_buffers. This has a positive impact on import accuracy but may affect performance when run with a large number (100+) of loaded buffers.

Instead of priority, you could also set import_all_select_source to true, which will prompt you to choose from the available options when there's a conflict.
Import missing import under cursor (exposed as :TSLspImportCurrent)

Adds the missing import under the cursor. Affected by the same options as :TSLspImportAll.
Import on completion

Adds missing imports on completion confirm (<C-y>) when using the built-in LSP omnifunc. Enable by setting enable_import_on_completion to true inside setup (see below).
Avoid organizing imports

By default always_organize_imports is set to true, every call to :TSLspImportAll or :TSLspImportCurrent will also run :TSLspOrganize to fix possible duplicated imports.

If always_organize_imports is set to false, it will only run :TSLspOrganize in situations where is necessary: i.e. two new imports from the same module.
Fix invalid ranges

tsserver uses non-compliant ranges in some code actions (most notably "Move to a new file"), which makes them not work properly in Neovim. The plugin fixes these ranges so that the affected actions work as expected.

You can enable this feature by calling setup_client in your configuration (see below).
Inlay hints (exposed as :TSLspInlayHints/:TSLspDisableInlayHints/:TSLspToggleInlayHints)

tsserver has added experimental support for inlay hints as of Typescript v4.4.2. Note that you need to set init_options for this feature to work. Please see Setup for instructions.

Supports the following settings:
- auto_inlay_hints (boolean): Set inlay hints on every new buffer visited automatically. Note that it would stop doing so if you call :TSDisableInlayHints and will continue if you call :TSLspInlayHints. If false, you need to call :TSInlayHints for every buffer to see its inlay hints. Defaults to true.
- inlay_hints_highlight (string): Highlight group used for inlay hints. Defaults to "Comment".
- inlay_hints_priority (number): Priority of the hint extmarks. Change this value if the inlay hints conflict with other extmarks. Defaults to 200.
- inlay_hints_throttle (number): Throttle time of inlay hints requests in ms. Defaults to 150.
- inlay_hints_format (table): Format options for individual kind of inlay hints. See Setup section for default settings and example.
Filter tsserver diagnostics

Some tsserver diagnostics may be annoying or can result in duplicated messages when used with a linter. For example, to disable the hint about RequireJS modules, set filter_out_diagnostics_by_code to { 80001 } and to disable all hints, set filter_out_diagnostics_by_severity to { "hint" }.

Like fixing invalid ranges, this function requires calling setup_client in your configuration (see below).

Note: filtering out error code 2304 (unused variables) will break :TSLspImportAll functionality.

Experimental Features

Update imports on file move

Watches the root directory for file move / rename events and updates imports accordingly. The plugin will attempt to determine if the current root directory has a Git root and watch all non-ignored directories.

Supports the following settings:
- update_imports_on_move (boolean): enables this feature. Set to false by default.
- require_confirmation_on_move (boolean): if true, prompts for confirmation before updating imports. Set to false by default.
- watch_dir (string, nil): sets a fallback directory that the plugin will watch for changes if it can't find a Git root from the current root directory. Path is relative to the current root directory. Set to nil by default.
Note that if the root directory does not have a Git root and watch_dir is nil or fails to resolve, the plugin will not enable file watching. This is to prevent performance issues from watching node_modules and irreversible changes from modifying files not under version control.

Setup

Install using your favorite plugin manager and add to your nvim-lspconfig tsserver.setup function.

An example showing the available settings and their defaults:

local lspconfig = require("lspconfig")

lspconfig.tsserver.setup({
    -- Needed for inlayHints. Merge this table with your settings or copy
    -- it from the source if you want to add your own init_options.
    init_options = require("nvim-lsp-ts-utils").init_options,
    --
    on_attach = function(client, bufnr)
        local ts_utils = require("nvim-lsp-ts-utils")

        -- defaults
        ts_utils.setup({
            debug = false,
            disable_commands = false,
            enable_import_on_completion = false,

            -- import all
            import_all_timeout = 5000, -- ms
            -- lower numbers = higher priority
            import_all_priorities = {
                same_file = 1, -- add to existing import statement
                local_files = 2, -- git files or files with relative path markers
                buffer_content = 3, -- loaded buffer content
                buffers = 4, -- loaded buffer names
            },
            import_all_scan_buffers = 100,
            import_all_select_source = false,
            -- if false will avoid organizing imports
            always_organize_imports = true,

            -- filter diagnostics
            filter_out_diagnostics_by_severity = {},
            filter_out_diagnostics_by_code = {},

            -- inlay hints
            auto_inlay_hints = true,
            inlay_hints_highlight = "Comment",
            inlay_hints_priority = 200, -- priority of the hint extmarks
            inlay_hints_throttle = 150, -- throttle the inlay hint request
            inlay_hints_format = { -- format options for individual hint kind
                Type = {},
                Parameter = {},
                Enum = {},
                -- Example format customization for `Type` kind:
                -- Type = {
                --     highlight = "Comment",
                --     text = function(text)
                --         return "->" .. text:sub(2)
                --     end,
                -- },
            },

            -- update imports on file move
            update_imports_on_move = false,
            require_confirmation_on_move = false,
            watch_dir = nil,
        })

        -- required to fix code action ranges and filter diagnostics
        ts_utils.setup_client(client)

        -- no default maps, so you may want to define some here
        local opts = { silent = true }
        vim.api.nvim_buf_set_keymap(bufnr, "n", "gs", ":TSLspOrganize<CR>", opts)
        vim.api.nvim_buf_set_keymap(bufnr, "n", "gr", ":TSLspRenameFile<CR>", opts)
        vim.api.nvim_buf_set_keymap(bufnr, "n", "gi", ":TSLspImportAll<CR>", opts)
    end,
})

Integrations via null-ls

You may want to set up integrations via null-ls.nvim to provide formatting, diagnostics, and code actions.

null-ls includes these integrations out-of-the-box, so they don't depend on this plugin, but since I consider them an integral part of the TypeScript development experience, I'm including instructions here for ESLint and Prettier, two common options.

Setting up null-ls

To enable null-ls and set up integrations, install it via your plugin manager and add the following snippet to your LSP configuration:

local null_ls = require("null-ls")
null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.eslint, -- eslint or eslint_d
        null_ls.builtins.code_actions.eslint, -- eslint or eslint_d
        null_ls.builtins.formatting.prettier -- prettier, eslint, eslint_d, or prettierd
    },
})

null-ls provides other built-in sources for the JavaScript ecosystem. I've included some alternatives above, and you can see the full list here. To set up more sources, add them to the sources table in null_ls.setup.

To learn about formatting files and setting up formatting on save, check out the null-ls FAQ. To see the full list of configuration options, see the config documentation.

Configuring sources

null-ls allows configuring built-in sources via the with method, which you can learn about here.

For example, to configure eslint to use a project-local executable from node_modules when available but fall back to a global executable, use this configuration:

local null_ls = require("null-ls")
null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.eslint.with({
            prefer_local = "node_modules/.bin",
        }),
    },
})

To configure eslint to only run when a project-local executable is available in node_modules, use the following:

local null_ls = require("null-ls")
null_ls.setup({
    sources = {
        null_ls.builtins.diagnostics.eslint.with({
            only_local = "node_modules/.bin",
        }),
    },
})

You can use the same options for prettier or any other built-in source.

ESLint Notes

Vanilla eslint is absurdly slow and you'll see a noticeable delay on each action when using it. If possible, I highly, highly recommend using eslint_d. It works out-of-the-box for diagnostics and code actions and can also work as a formatter via eslint-plugin-prettier.
Since null-ls wraps the ESLint CLI, it may have trouble handling complex project structures. For these cases (e.g. monorepos), I recommend the ESLint language server, which can also provide diagnostics, code actions, and ESLint formatting.

Troubleshooting

Make sure you are running the latest version of this plugin and its dependencies.
Check your configuration and make sure it's in line with the latest version of this document.
Set debug = true in your config and inspect the output in :messages to see if it matches what you expect.

If those options don't help, please open up an issue and provide the requested information.

If you have a question or issue related to null-ls, please post a discussion question or open an issue on the null-ls repository.

Tests

Clone the repository and run make test. The suite has the same requirements as the plugin.
