💤 lazy.nvim

lazy.nvim is a modern plugin manager for Neovim.

✨ Features

• 📦 Manage all your Neovim plugins with a sleek and intuitive UI
• 🚀 Fast startup times thanks to automatic caching and bytecode compilation of lua modules.
• 💾 Partial clones instead of shallow clones
• 🔌 Automatic lazy-loading of lua modules and lazy-loading on events, commands, filetypes, and key mappings.
• ⏳ Automatically install missing plugins before starting up Neovim, allowing you to start using it right away.
• 💪 Async execution for improved performance
• 🛠️ No need to manually compile plugins
• 🧪 Correct sequencing of dependencies
• 📁 Configurable in multiple files
• 📚 Generates helptags of the headings in README.md files for plugins that don't have vimdocs
• 💻 Dev options and patterns for using local plugins
• 📊 Profiling tools to optimize performance
• 🔒 Lockfile lazy-lock.json to keep track of installed plugins
• 🔎 Automatically check for updates
• 📋 Commit, branch, tag, version, and full Semver support
• 📈 Statusline component to see the number of pending updates

⚡️ Requirements

• Neovim >= 0.8.0 (needs to be built with LuaJIT)
• Built for Linux and MacOS
• Git >= 2.19.0 (for partial clones support)

📦 Installation

You can use the following Lua code to bootstrap lazy.nvim

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
 if not vim.loop.fs_stat(lazypath) then
   vim.fn.system({
     "git",
     "clone",
     "--filter=blob:none",
     "--single-branch",
     "git@github.com:folke/lazy.nvim.git",
     lazypath,
   })
 end
 vim.opt.runtimepath:prepend(lazypath)

Next step is to add lazy.nvim to the top of your init.lua

-- You can use a lua module that contains your plugins.
-- All sub modules of the lua module will also be automatically loaded
-- This is the preferred setup so your plugin specs can be properly cached.
require("lazy").setup("config.plugins", {
  -- add any optional configuration here
})

-- Alternatively you can specify a plugin list
require("lazy").setup({
    "folke/neodev.nvim",
    "folke/which-key.nvim",
    { "folke/neoconf.nvim", cmd = "Neoconf" },
  }, {
  -- add any optional configuration here
})

🔌 Plugin Spec

Property	Type	Description
[1]	string?	Short plugin url. Will be expanded using config.git.url_format
dir	string?	A directory pointing to a local plugin
url	string?	A custom git url where the plugin is hosted
name	string?	A custom name for the plugin used for the local plugin directory and as the dispay name
dev	boolean?	When true, a local plugin directory will be used instead. See config.dev
lazy	boolean?	When true, the plugin will only be loaded when needed. Lazy-loaded plugins are automatically loaded when their lua modules are required, or when one of the laz-loading handlers triggers
enabled	boolean? or fun():boolean	When false, or if the function returns false, then this plugin will not be used
dependencies	LazySpec[]	A list of plugin specs that should be loaded when the plugin loads. Dependencies are always lazy-loaded unless specified otherwise
init	fun(LazyPlugin)	init functions are always executed during startup
config	fun(LazyPlugin)	config is executed when the plugin loads
build	fun(LazyPlugin)	build is executed when a plugin is installed or updated
branch	string?	Branch of the repository
tag	string?	Tag of the repository
commit	string?	Commit of the repository
version	string?	Version to use from the repository. Full Semver ranges are supported
pin	boolean?	When true, this plugin will not be included in updates
event	string? or string[]	Lazy-load on event
cmd	string? or string[]	Lazy-load on command
ft	string? or string[]	Lazy-load on filetype
keys	string? or string[]	Lazy-load on key mapping

Lazy Loading

lazy.nvim automagically lazy-loads Lua modules, so it is not needed to specify module=... everywhere in your plugin specification. This mean that if you have a plugin A that is lazy-loaded and a plugin B that requires a module of plugin A, then plugin A will be loaded on demand as expected.

You can configure lazy.nvim to lazy-load all plugins by default with config.defaults.lazy = true.

Additionally, you can also lazy-load on events, commands, file types and key mappings.

Plugins will be lazy-loaded when one of the following is true:

• the plugin only exists as a dependency in your spec
• it has an event, cmd, ft or cmd key
• it defines an init method
• config.defaults.lazy == true

Versioning

If you want to install a specific revision of a plugin, you can use commit, tag, branch, version.

The version property supports Semver ranges:

• *: latest stable version (this excludes pre-release versions)
• 1.2.x: any version that starts with 1.2, such as 1.2.0, 1.2.3, etc.
• ^1.2.3: any version that is compatible with 1.2.3, such as 1.3.0, 1.4.5, etc., but not 2.0.0.
• ~1.2.3: any version that is compatible with 1.2.3, such as 1.2.4, 1.2.5, but not 1.3.0.
• >1.2.3: any version that is greater than 1.2.3, such as 1.3.0, 1.4.5, etc.
• >=1.2.3: any version that is greater than or equal to 1.2.3, such as 1.2.3, 1.3.0, 1.4.5, etc.
• <1.2.3: any version that is less than 1.2.3, such as 1.1.0, 1.0.5, etc.
• <=1.2.3: any version that is less than or equal to 1.2.3, such as 1.2.3, 1.1.0, 1.0.5, etc

You can set config.defaults.version = "*" to install the latest stable version of plugins that support Semver.

Examples

My personal dots:

• init.lua where I require config.lazy
• config.lazy where I bootstrap and setup lazy.nvim
• config.plugins is my main plugin config module
• Any submodule of config.plugins (submodules) will be automatically loaded as well.

Other examples:

return {
  -- the colorscheme should be available when starting Neovim
  "folke/tokyonight.nvim",

  -- I have a separate config.mappings file where I require which-key.
  -- With lazy the plugin will be automatically loaded when it is required somewhere
  { "folke/which-key.nvim", lazy = true },

  {
    "nvim-neorg/neorg",
    -- lazy-load on filetype
    ft = "norg",
    -- custom config that will be executed when loading the plugin
    config = function()
      require("neorg").setup()
    end,
  },

  {
    "dstein64/vim-startuptime",
    -- lazy-load on a command
    cmd = "StartupTime",
  },

  {
    "hrsh7th/nvim-cmp",
    -- load cmp on InsertEnter
    event = "InsertEnter",
    -- these dependencies will only be loaded when cmp loads
    -- dependencies are always lazy-loaded unless specified otherwise
    dependencies = {
      "hrsh7th/cmp-nvim-lsp",
      "hrsh7th/cmp-buffer",
    },
    config = function()
      -- ...
    end,
  },

  -- you can use the VeryLazy event for things that can
  -- load later and are not important for the initial UI
  { "stevearc/dressing.nvim", event = "VeryLazy" },

  {
    "cshuaimin/ssr.nvim",
    -- init is always executed during startup, but doesn't load the plugin yet.
    -- init implies lazy loading
    init = function()
      vim.keymap.set({ "n", "x" }, "<leader>cR", function()
        -- this require will automatically load the plugin
        require("ssr").open()
      end, { desc = "Structural Replace" })
    end,
  },

  {
    "monaqa/dial.nvim",
    -- lazy-load on keys
    keys = { "<C-a>", "<C-x>" },
  },

  -- local plugins need to be explicitely configured with dir
  { dir = "~/projects/secret.nvim" },

  -- you can use a custom url to fetch a plugin
  { url = "git@github.com:folke/noice.nvim.git" },

  -- local plugins can also be configure with the dev option.
  -- This will use ~/projects/noice.nvim/ instead of fetching it from Github
  -- With the dev option, you can easily switch between the local and installed version of a plugin
  { "folke/noice.nvim", dev = true },
}

⚙️ Configuration

lazy.nvim comes with the following defaults:

{
  root = vim.fn.stdpath("data") .. "/lazy", -- directory where plugins will be installed
  defaults = {
    lazy = false, -- should plugins be lazy-loaded?
    version = nil,
    -- version = "*", -- enable this to try installing the latest stable versions of plugins
  },
  lockfile = vim.fn.stdpath("config") .. "/lazy-lock.json", -- lockfile generated after running update.
  concurrency = nil, ---@type number limit the maximum amount of concurrent tasks
  git = {
    -- defaults for the `Lazy log` command
    -- log = { "-10" }, -- show the last 10 commits
    log = { "--since=1 days ago" }, -- show commits from the last 3 days
    timeout = 120, -- kill processes that take more than 2 minutes
    url_format = "https://github.com/%s.git",
  },
  dev = {
    -- directory where you store your local plugin projects
    path = vim.fn.expand("~/projects"),
    ---@type string[] plugins that match these patterns will use your local versions instead of being fetched from GitHub
    patterns = {}, -- For example {"folke"}
  },
  install = {
    -- install missing plugins on startup. This doesn't increase startup time.
    missing = true,
    -- try to load one of these colorschemes when starting an installation during startup
    colorscheme = { "habamax" },
  },
  ui = {
    -- The border to use for the UI window. Accepts same border values as |nvim_open_win()|.
    border = "none",
    icons = {
      cmd = " ",
      config = "",
      event = "",
      ft = " ",
      init = " ",
      keys = " ",
      plugin = " ",
      runtime = " ",
      source = " ",
      start = "",
      task = "✔ ",
    },
    throttle = 20, -- how frequently should the ui process render events
  },
  checker = {
    -- automcatilly check for plugin updates
    enabled = false,
    concurrency = nil, ---@type number? set to 1 to check for updates very slowly
    notify = true, -- get a notification when new updates are found
    frequency = 3600, -- check for updates every hour
  },
  performance = {
    cache = {
      enabled = true,
      path = vim.fn.stdpath("state") .. "/lazy.state",
      -- Once one of the following events triggers, caching will be disabled.
      -- To cache all modules, set this to `{}`, but that is not recommended.
      -- The default is to disable on:
      --  * VimEnter: not useful to cache anything else beyond startup
      --  * BufReadPre: this will be triggered early when opening a file from the command line directly
      disable_events = { "VimEnter", "BufReadPre" },
    },
    reset_packpath = true, -- reset the package path to improve startup time
    rtp = {
      reset = true, -- reset the runtime path to $VIMRUNTIME and your config directory
      ---@type string[] list any plugins you want to disable here
      disabled_plugins = {
        -- "gzip",
        -- "matchit",
        -- "matchparen",
        -- "netrwPlugin",
        -- "tarPlugin",
        -- "tohtml",
        -- "tutor",
        -- "zipPlugin",
      },
    },
  },
  -- lazy can generate helptags from the headings in markdown readme files,
  -- so :help works even for plugins that don't have vim docs.
  -- when the readme opens with :help it will be correctly displayed as markdown
  readme = {
    root = vim.fn.stdpath("state") .. "/lazy/readme",
    files = { "README.md" },
    -- only generate markdown helptags for plugins that dont have docs
    skip_if_doc_exists = true,
  },
}

🚀 Usage

You can manage all your plugins with the main :Lazy command. Alternatively you can start any operation with a specific command, sub command or API function:

:Lazy install or :LazyInstall	require("lazy").install()	<I>	Install missing plugins
:Lazy update or :LazyUpdate	require("lazy").update()	<U>	Update all plugins. This will also update the lockfile
:Lazy sync or :LazySync	require("lazy").sync()	<S>	Run install, clean and update
:Lazy clean or :LazyClean	require("lazy").clean()	<X>	Clean plugins that are no longer needed
:Lazy check or :LazyCheck	require("lazy").check()	<C>	Check for updates and show the log (git fetch)
:Lazy log or :LazyLog	require("lazy").log()	<L>	Show recent updates for all plugins
:Lazy restore or :LazyRestore	require("lazy").restore()	<R>	Updates all plugins to the state in the lockfile
:Lazy profile or :LazyProfile	require("lazy").profile()	<P>	Show detailed profiling

▶️ Startup Sequence

lazy.nvim does NOT use Neovim packages and even disables plugin loading completely (vim.go.loadplugins = false). It takes over the complete startup sequence for more flexibility and better performance.

In practice this means that step 10 of Neovim Initialization is done by Lazy:

1. all files from /plugin and /ftdetect directories in you rtp are sourced (excluding /after)
2. all plugins with lazy=false are loaded. This includes sourcing /plugin and /ftdetect files. (/after will not be sourced yet)
3. all plugins' /after/plugin files are sourced
4. all /after/plugin files from the original rtp are sourced
5. all the plugins' init() functions are executed

Files from runtime directories are always sourced in alphabetical order.

📦 Differences with Packer

• Plugin Spec:

  • setup => init
  • requires => dependencies
  • as => name
  • opt => lazy
  • run => build
  • lock => pin
  • module is auto-loaded. No need to specify

📦 Other Neovim Plugin Managers in Lua

• packer.nvim
• paq-nvim
• neopm
• dep
• optpack.nvim
