🚀 Getting Started
lazy.nvim is a modern plugin manager for Neovim.
✨ Features
- 📦 Manage all your Neovim plugins with a powerful 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
- 🎨 Automatically lazy-loads colorschemes
⚡️ Requirements
- Neovim >= 0.8.0 (needs to be built with LuaJIT)
- Git >= 2.19.0 (for partial clones support)
- a Nerd Font (optional)
🛠️ Installation
There are multiple ways to install lazy.nvim.
The Structured Setup is the recommended way, but you can also use the Single File Setup
if you prefer to keep everything in your init.lua
.
Please refer to the Configuration section for an overview of all available options.
:::tip
It is recommended to run :checkhealth lazy
after installation.
:::
:::note
In what follows ~/.config/nvim
is your Neovim configuration directory.
On Windows, this is usually ~\AppData\Local\nvim
.
To know the correct path for your system, run :echo stdpath('config')
.
:::
Structured Setup
require("config.lazy")
-- Bootstrap lazy.nvim
local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
local lazyrepo = "https://github.com/folke/lazy.nvim.git"
vim.fn.system({ "git", "clone", "--filter=blob:none", "--branch=stable", lazyrepo, lazypath })
end
vim.opt.rtp:prepend(lazypath)
-- Make sure to setup `mapleader` and `maplocalleader` before
-- loading lazy.nvim so that mappings are correct.
-- This is also a good place to setup other settings (vim.opt)
vim.g.mapleader = " "
vim.g.maplocalleader = "\\"
-- Setup lazy.nvim
require("lazy").setup({
-- highlight-start
spec = {
-- import your plugins
{ import = "plugins" },
},
-- highlight-end
-- Configure any other settings here. See the documentation for more details.
-- colorscheme that will be used when installing plugins.
install = { colorscheme = { "habamax" } },
-- automatically check for plugin updates
checker = { enabled = true },
})
You can then create your plugin specs in ~/.config/nvim/lua/plugins/
.
Each file should return a table with the plugins you want to install.

🔌 Plugin Spec
Spec Source
Property | Type | Description |
---|---|---|
[1] | string? |
Short plugin url. Will be expanded using config.git.url_format . Can also be a url or dir . |
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 display name |
dev | boolean? |
When true , a local plugin directory will be used instead. See config.dev |
A valid spec should define one of [1]
, dir
or url
.
Spec Loading
Property | Type | Description |
---|---|---|
dependencies | LazySpec[] |
A list of plugin names or plugin specs that should be loaded when the plugin loads. Dependencies are always lazy-loaded unless specified otherwise. When specifying a name, make sure the plugin spec has been defined somewhere else. |
enabled | boolean? or fun():boolean |
When false , or if the function returns false, then this plugin will not be included in the spec |
cond | boolean? or fun(LazyPlugin):boolean |
Behaves the same as enabled , but won't uninstall the plugin when the condition is false . Useful to disable some plugins in vscode, or firenvim for example. |
priority | number? |
Only useful for start plugins (lazy=false ) to force loading certain plugins first. Default priority is 50 . It's recommended to set this to a high number for colorschemes. |
Spec Setup
Property | Type | Description |
---|---|---|
init | fun(LazyPlugin) |
init functions are always executed during startup |
opts | table or fun(LazyPlugin, opts:table) |
opts should be a table (will be merged with parent specs), return a table (replaces parent specs) or should change a table. The table will be passed to the Plugin.config() function. Setting this value will imply Plugin.config() |
config | fun(LazyPlugin, opts:table) or true |
config is executed when the plugin loads. The default implementation will automatically run require(MAIN).setup(opts) if opts or config = true is set. Lazy uses several heuristics to determine the plugin's MAIN module automatically based on the plugin's name. See also opts . To use the default implementation without opts set config to true . |
main | string? |
You can specify the main module to use for config() and opts() , in case it can not be determined automatically. See config() |
build | fun(LazyPlugin) or string or a list of build commands |
build is executed when a plugin is installed or updated. Before running build , a plugin is first loaded. If it's a string it will be run as a shell command. When prefixed with : it is a Neovim command. You can also specify a list to executed multiple build commands. Some plugins provide their own build.lua which is automatically used by lazy. So no need to specify a build step for those plugins. |
rocks | string[]? |
Add any luarocks dependencies. |
Spec Lazy Loading
Property | Type | Description |
---|---|---|
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 lazy-loading handlers triggers |
event | string? or string[] or fun(self:LazyPlugin, event:string[]):string[] or {event:string[]|string, pattern?:string[]|string} |
Lazy-load on event. Events can be specified as BufEnter or with a pattern like BufEnter *.lua |
cmd | string? or string[] or fun(self:LazyPlugin, cmd:string[]):string[] |
Lazy-load on command |
ft | string? or string[] or fun(self:LazyPlugin, ft:string[]):string[] |
Lazy-load on filetype |
keys | string? or string[] or LazyKeysSpec[] or fun(self:LazyPlugin, keys:string[]):(string | LazyKeysSpec)[] |
Lazy-load on key mapping |
Refer to the Lazy Loading section for more information.
Spec Versioning
Property | Type | Description |
---|---|---|
branch | string? |
Branch of the repository |
tag | string? |
Tag of the repository |
commit | string? |
Commit of the repository |
version | string? or false to override the default |
Version to use from the repository. Full Semver ranges are supported |
pin | boolean? |
When true , this plugin will not be included in updates |
submodules | boolean? |
When false, git submodules will not be fetched. Defaults to true |
Refer to the Versioning section for more information.
Spec Advanced
Property | Type | Description |
---|---|---|
optional | boolean? |
When a spec is tagged optional, it will only be included in the final spec, when the same plugin has been specified at least once somewhere else without optional . This is mainly useful for Neovim distros, to allow setting options on plugins that may/may not be part of the user's plugins. |
specs | LazySpec |
A list of plugin specs defined in the scope of the plugin. This is mainly useful for Neovim distros, to allow setting options on plugins that may/may not be part of the user's plugins. When the plugin is disabled, none of the scoped specs will be included in the final spec. Similar to dependencies without the automatic loading of the specs. |
module | false? |
Do not automatically load this Lua module when it's required somewhere |
import | string? |
Import the given spec module. |

-- local plugins need to be explicitly 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 configured with the dev option.
-- This will use {config.dev.path}/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 },
}
Lazy Loading
lazy.nvim automagically lazy-loads Lua modules. This means 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.
:::tip
You can configure lazy.nvim to lazy-load all plugins by default with config.defaults.lazy = true
.
Make sure you've configured lazy-loading, for your plugins to avoid unexpected behavior.
Only do this if you know what you are doing, as it can lead to unexpected behavior.
:::
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
orkeys
key config.defaults.lazy == true
🌈 Colorschemes
Colorscheme plugins can be configured with lazy=true
. The plugin will automagically load
when doing colorscheme foobar
.
:::warning
since start plugins can possibly change existing highlight groups,
it's important to make sure that your main colorscheme is loaded first.
To ensure this you can use the priority=1000
field. (see the examples)
:::
⌨️ Lazy Key Mappings
The keys
property can be a string
or string[]
for simple normal-mode mappings, or it
can be a LazyKeysSpec
table with the following key-value pairs:
- [1]: (
string
) lhs (required) - [2]: (
string|fun()
) rhs (optional) - mode: (
string|string[]
) mode (optional, defaults to"n"
) - ft: (
string|string[]
)filetype
for buffer-local keymaps (optional) - any other option valid for
vim.keymap.set
Key mappings will load the plugin the first time they get executed.
When [2]
is nil
, then the real mapping has to be created by the config()
function.
-- Example for neo-tree.nvim
{
"nvim-neo-tree/neo-tree.nvim",
keys = {
{ "<leader>ft", "<cmd>Neotree toggle<cr>", desc = "NeoTree" },
},
config = function()
require("neo-tree").setup()
end,
}
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.
:::tip
You can set config.defaults.version = "*"
to install the latest stable
version of plugins that support Semver.
:::
Examples
*
: latest stable version (this excludes pre-release versions)1.2.x
: any version that starts with1.2
, such as1.2.0
,1.2.3
, etc.^1.2.3
: any version that is compatible with1.2.3
, such as1.3.0
,1.4.5
, etc., but not2.0.0
.~1.2.3
: any version that is compatible with1.2.3
, such as1.2.4
,1.2.5
, but not1.3.0
.>1.2.3
: any version that is greater than1.2.3
, such as1.3.0
,1.4.5
, etc.>=1.2.3
: any version that is greater than or equal to1.2.3
, such as1.2.3
,1.3.0
,1.4.5
, etc.<1.2.3
: any version that is less than1.2.3
, such as1.1.0
,1.0.5
, etc.<=1.2.3
: any version that is less than or equal to1.2.3
, such as1.2.3
,1.1.0
,1.0.5
, etc
📦 Packages
lazy.nvim supports three ways for plugins to define their dependencies and configuration.
- Lazy:
lazy.lua
file - Rockspec: luarocks
*-scm-1.rockspec
file - Packspec:
pkg.json
(experimental, since the format is not quite there yet)
You can enable/disable package sources with config.pkg.sources
.
The order of sources is important, as the first source that finds a package will be used.
:::info
Package specs are always loaded in the scope of the plugin (using specs), so that when the plugin is disabled, none of the specs are loaded.
:::
Lazy
Using a lazy.lua
file is the recommended way to define your plugin dependencies and configuration.
Syntax is the same as any plugin spec.
Rockspec
When a plugin contains a *-scm-1.rockspec
file, lazy.nvim will automatically load its rocks
dependencies.
Packspec
Supports the pkg.json format,
with a lazy extension in lazy
.
lazy
can contain any valid lazy spec fields. They will be added to the plugin's spec.
⚙️ Configuration
lazy.nvim comes with the following defaults:
{
root = vim.fn.stdpath("data") .. "/lazy", -- directory where plugins will be installed
defaults = {
-- Set this to `true` to have all your plugins lazy-loaded by default.
-- Only do this if you know what you are doing, as it can lead to unexpected behavior.
lazy = false, -- should plugins be lazy-loaded?
-- It's recommended to leave version=false for now, since a lot the plugin that support versioning,
-- have outdated releases, which may break your Neovim install.
version = nil, -- always use the latest git commit
-- version = "*", -- try installing the latest stable version for plugins that support semver
-- default `cond` you can use to globally disable a lot of plugins
-- when running inside vscode for example
cond = nil, ---@type boolean|fun(self:LazyPlugin):boolean|nil

🚀 Usage
▶️ 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:
- All the plugins'
init()
functions are executed - All plugins with
lazy=false
are loaded. This includes sourcing/plugin
and/ftdetect
files. (/after
will not be sourced yet) - All files from
/plugin
and/ftdetect
directories in your rtp are sourced (excluding/after
) - All
/after/plugin
files are sourced (this includes/after
from plugins)
Files from runtime directories are always sourced in alphabetical order.
🚀 Commands
Plugins are managed with the :Lazy
command.
Open the help with <?>
to see all the key mappings.
You can press <CR>
on a plugin to show its details. Most properties
can be hovered with <K>
to open links, help files, readmes,
git commits and git issues.
Lazy can automatically check for updates in the background. This feature
can be enabled with config.checker.enabled = true
.
Any operation can be started from the UI, with a sub command or an API function:

Run install, clean and update |
:Lazy update [plugins] |
require("lazy").update(opts?) |
Update plugins. This will also update the lockfile |
Any command can have a bang to make the command wait till it finished. For example, if you want to sync lazy from the cmdline, you can use:
nvim --headless "+Lazy! sync" +qa
opts
is a table with the following key-values:
- wait: when true, then the call will wait till the operation completed
- show: when false, the UI will not be shown
- plugins: a list of plugin names to run the operation on
- concurrency: limit the
number
of concurrently running tasks
Stats API (require("lazy").stats()
):
{
-- startuptime in milliseconds till UIEnter
startuptime = 0,
-- when true, startuptime is the accurate cputime for the Neovim process. (Linux & macOS)
-- this is more accurate than `nvim --startuptime`, and as such will be slightly higher
-- when false, startuptime is calculated based on a delta with a timestamp when lazy started.
real_cputime = false,
count = 0, -- total number of plugins
loaded = 0, -- number of loaded plugins
---@type table<string, number>
times = {},
}
lazy.nvim provides a statusline component that you can use to show the number of pending updates.
Make sure to enable config.checker.enabled = true
to make this work.
Example of configuring lualine.nvim
require("lualine").setup({
sections = {
lualine_x = {
{
require("lazy.status").updates,
cond = require("lazy.status").has_updates,
color = { fg = "#ff9e64" },
},
},
},
})
📆 User Events
The following user events will be triggered:
- LazyDone: when lazy has finished starting up and loaded your config
- LazySync: after running sync
- LazyInstall: after an install
- LazyUpdate: after an update
- LazyClean: after a clean
- LazyCheck: after checking for updates
- LazyLog: after running log
- LazyLoad: after loading a plugin. The
data
attribute will contain the plugin name. - LazySyncPre: before running sync
- LazyInstallPre: before an install
- LazyUpdatePre: before an update
- LazyCleanPre: before a clean
- LazyCheckPre: before checking for updates
- LazyLogPre: before running log
- LazyReload: triggered by change detection after reloading plugin specs
- VeryLazy: triggered after
LazyDone
and processingVimEnter
auto commands - LazyVimStarted: triggered after
UIEnter
whenrequire("lazy").stats().startuptime
has been calculated. Useful to update the startuptime on your dashboard.
❌ Uninstalling
To uninstall lazy.nvim, you need to remove the following files and directories:
- data:
~/.local/share/nvim/lazy
- state:
~/.local/state/nvim/lazy
- lockfile:
~/.config/nvim/lazy-lock.json
Paths can differ if you changed
XDG
environment variables.
🔒 Lockfile
After every update, the local lockfile (lazy-lock.json
) is updated with the installed revisions.
It is recommended to have this file under version control.
If you use your Neovim config on multiple machines, using the lockfile, you can ensure that the same version of every plugin is installed.
If you are on another machine, you can do :Lazy restore
, to update all your plugins to
the version from the lockfile.

With packer wants
, requires
and after
can be used to manage dependencies.
With lazy, this isn't needed for most of the Lua dependencies. They can be installed just like normal plugins
(even with lazy=true
) and will be loaded when other plugins need them.
The dependencies
key can be used to group those required plugins with the one that requires them.
The plugins which are added as dependencies
will always be lazy-loaded and loaded when the plugin is loaded.

⚡ Profiling & Debug
Great care has been taken to make the startup code (lazy.core
) as efficient as possible.
During startup, all Lua files used before VimEnter
or BufReadPre
are byte-compiled and cached,
similar to what impatient.nvim does.
My config for example loads in about 11ms
with 93
plugins. I do a lot of lazy-loading though :)
lazy.nvim comes with an advanced profiler :Lazy profile
to help you improve performance.
The profiling view shows you why and how long it took to load your plugins.

📂 Structuring Your Plugins
Some users may want to split their plugin specs in multiple files.
Instead of passing a spec table to setup()
, you can use a Lua module.
The specs from the module and any top-level sub-modules will be merged together in the final spec,
so it is not needed to add require
calls in your main plugin file to the other files.
The benefits of using this approach:
- Simple to add new plugin specs. Just create a new file in your plugins module.
- Allows for caching of all your plugin specs. This becomes important if you have a lot of smaller plugin specs.
- Spec changes will automatically be reloaded when they're updated, so the
:Lazy
UI is always up to date.
Example:
~/.config/nvim/init.lua
require("lazy").setup("plugins")
~/.config/nvim/lua/plugins.lua
or~/.config/nvim/lua/plugins/init.lua
(this file is optional)
return {
"folke/neodev.nvim",
"folke/which-key.nvim",
{ "folke/neoconf.nvim", cmd = "Neoconf" },
}
- Any lua file in
~/.config/nvim/lua/plugins/*.lua
will be automatically merged in the main plugin spec
For a real-life example, you can check LazyVim and more specifically:
- lazyvim.plugins contains all the plugin specs that will be loaded
↩️ Importing Specs, config
& opts
As part of a spec, you can add import
statements to import additional plugin modules.
Both of the setup()
calls are equivalent:
require("lazy").setup("plugins")
-- Same as:
require("lazy").setup({{import = "plugins"}})
To import multiple modules from a plugin, add additional specs for each import. For example, to import LazyVim core plugins and an optional plugin:
require("lazy").setup({
spec = {
{ "LazyVim/LazyVim", import = "lazyvim.plugins" },
{ import = "lazyvim.plugins.extras.coding.copilot" },
}
})
When you import specs, you can override them by simply adding a spec for the same plugin to your local specs, adding any keys you want to override / merge.
opts
, dependencies
, cmd
, event
, ft
and keys
are always merged with the parent spec.
Any other property will override the property from the parent spec.
📚 Plugin Developers
To make it easier for users to install your plugin, you can include a package spec in your repo.
If your plugin needs a build step, you can specify this in your package file,
or create a file build.lua
or build/init.lua
in the root of your repo.
This file will be loaded when the plugin is installed or updated.
This makes it easier for users, as they no longer need to specify a build
command.
