# Lifecycle Hooks
Nuxt provides a powerful hooking system to expand almost every aspect using hooks powered by [unjs/hookable](https://github.com/unjs/hookable).
## Nuxt Hooks (build time)
These hooks are available for [Nuxt Modules](/guide/going-further/modules) and build context.
### Usage with `nuxt.config`
```js [nuxt.config]
export default defineNuxtConfig({
hooks: {
'close': () => { }
}
})
```
### Usage with Nuxt Modules
```js
import { defineNuxtModule } from '@nuxt/kit'
export default defineNuxtModule({
setup (options, nuxt) {
nuxt.hook('close', async () => { })
})
})
```
## App Hooks (runtime)
App hooks can be mainly used by [Nuxt Plugins](/guide/directory-structure/plugins) to hook into rendering lifecycle but could also be used in Vue composables.
### Usage with Plugins
```js [plugins/test.ts]
export defineNuxtPlugin(nuxtApp) {
nuxtApp.hook('page:start', () => { })
}
```
