Nuxt provides a powerful hooking system to expand almost every aspect using hooks powered by [unjs/hookable](https://github.com/unjs/hookable).
## Nuxt Hooks
This hooks are available for [Nuxt Modules](/docs/advanced/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 () => { })
})
})
```
### Available hooks
Check the [source code](https://github.com/nuxt/framework/blob/main/packages/schema/src/types/hooks.ts#L55) for all available hooks.
## Runtime Hooks
App hooks can be mainly used by [Nuxt Plugins] (/docs/directory-structure/plugins) to hook into rendering lifecycle but could also be used in Vue composables.
### Usage with Modules
```js [plugins/test.ts]
export defineNuxtPlugin(nuxtApp) {
nuxtApp.hook('page:start', () => { })
}
```
### Available hooks
Check the [source code](https://github.com/nuxt/framework/blob/main/packages/nuxt3/src/app/nuxt.ts#L18) for all available hooks.
