## Nuxt Hooks (Build Time)
|
|
|
|
These hooks are available for [Nuxt Modules](/docs/guide/going-further/modules) and build context.
|
|
|
|
### Within `nuxt.config`
|
|
|
|
```js [nuxt.config]
|
|
export default defineNuxtConfig({
|
|
hooks: {
|
|
close: () => { }
|
|
}
|
|
})
|
|
```
|
|
|
|
### Within 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](/docs/guide/directory-structure/plugins) to hook into rendering lifecycle but could also be used in Vue composables.
|
|
|
|
```js [plugins/test.ts]
|
|
export default defineNuxtPlugin((nuxtApp) => {
|
|
nuxtApp.hook('page:start', () => {
|
|
/* your code goes here */
|
|
})
|
|
})
|
|
```
|
|
|
|

|
|
|
|
## Server Hooks (Runtime)
|
|
|
|
These hooks are available for [server plugins](/docs/guide/directory-structure/server#server-plugins) to hook into Nitro's runtime behavior.
|
|
|
|
```js [~/server/plugins/test.ts]
|
|
export default defineNitroPlugin((nitroApp) => {
|
|
nitroApp.hooks.hook('render:html', (html, { event }) => {
|
|
console.log('render:html', html)
|
|
html.bodyAppend.push('<hr>Appended by custom plugin')
|
|
})
|
|
|
|
nitroApp.hooks.hook('render:response', (response, { event }) => {
|
|
console.log('render:response', response)
|
|
})
|
|
})
|
|
```

## Additional Hooks
|
|
|
|
You can add additional hooks by augmenting the types provided by Nuxt. This can be useful for modules.
|
|
|
|
```ts
|
|
import { HookResult } from "@nuxt/schema";
|
|
|
|
declare module '#app' {
|
|
interface RuntimeNuxtHooks {
|
|
'your-nuxt-runtime-hook': () => HookResult
|
|
}
|
|
interface NuxtHooks {
|
|
'your-nuxt-hook': () => HookResult
|
|
}
|
|
}
|
|
|
|
declare module 'nitro/types' {
|
|
interface NitroRuntimeHooks {
|
|
'your-nitro-hook': () => void;
|
|
}
|
|
}
|
|
```
