# Lazy Method {#sec-lazy-method}
> [!NOTE]
> This page covers the lazy-loading API for custom plugins. For a full reference
> of trigger events and the `LazyFile` event, see the
> [Lazy Loading](#ch-lazy-loading) chapter.
As of version **0.7**, an API is exposed to allow configuring lazy-loaded
plugins via `lz.n` and `lzn-auto-require`. Below is a comprehensive example of
how it may be loaded to lazy-load an arbitrary plugin.
```nix
{
config.vim.lazy.plugins = {
"aerial.nvim" = {
package = pkgs.vimPlugins.aerial-nvim;
setupModule = "aerial";
setupOpts = {
option_name = true;
};
after = ''
-- custom lua code to run after plugin is loaded
print('aerial loaded')
'';
# Explicitly mark plugin as lazy. You don't need this if you define one of
# the trigger "events" below
lazy = true;
# load on command
cmd = ["AerialOpen"];
# load on event
event = ["BufEnter"];
# load on keymap
keys = [
{
key = "<leader>a";
action = ":AerialToggle<CR>";
}
];
};
};
}
```
## LazyFile event {#sec-lazyfile-event}
**nvf** re-implements `LazyFile` as a familiar user event to load a plugin when
a file is opened:
```nix
{
config.vim.lazy.plugins = {
"aerial.nvim" = {
package = pkgs.vimPlugins.aerial-nvim;
event = [{event = "User"; pattern = "LazyFile";}];
# ...
};
};
}
```
You can consider the `LazyFile` event as an alias to the combination of
`"BufReadPost"`, `"BufNewFile"` and `"BufWritePre"`, i.e., a list containing all
three of those events: `["BufReadPost" "BufNewFile" "BufWritePre"]`
