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 */
})
})👉
