Lifecycle Hooks
Nuxt provides a powerful hooking system to expand almost every aspect using hooks.
The hooking system is powered by unjs/hookable.
Nuxt Hooks (Build Time)
These hooks are available for Nuxt Modules and build context.
Within nuxt.config
nuxt.config
export default defineNuxtConfig({ hooks: { close: () => { } }})Within 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.
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 to hook into Nitro's runtime behavior.
~/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.
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; }}
