Lifecycle Hooks

Nuxt provides a powerful hooking system to expand almost every aspect using hooks.

Lifecycle Hooks

Nuxt provides a powerful hooking system to expand almost every aspect using hooks. This feature is powered by unjs/hookable.

Nuxt Hooks (Build Time)

These hooks are available for Nuxt Modules and build context.

Usage with nuxt.config

nuxt.config
export default defineNuxtConfig({  hooks: {    'close': () => { }  }})

Usage with Nuxt Modules

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 to hook into rendering lifecycle but could also be used in Vue composables.

Usage with Plugins

plugins/test.ts
export default defineNuxtPlugin((nuxtApp) => {  nuxtApp.hook('page:start', () => {    /* your code goes here */  })})

Nitro App Hooks (Runtime)

These hooks are available for Nitro plugins to hook into Nitro's runtime behavior.

Usage within a Nitro Plugin

~/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)  })})

Add additional hooks

You can add additional hooks by augmenting the types provided by Nuxt. This can be useful for modules.

import { HookResult } from "@nuxt/schema";declare module '#app' {  interface RuntimeNuxtHooks {    'your-nuxt-runtime-hook': () => HookResult  }  interface NuxtHooks {    'your-nuxt-hook': () => HookResult  }}declare module 'nitropack' {  interface NitroRuntimeHooks {    'your-nitro-hook': () => void;  }}
