生命周期钩子

Nuxt 提供了一个强大的钩子系统,可以使用钩子来扩展几乎所有方面。
钩子系统由 unjs/hookable 提供支持。

Nuxt Hooks(构建时)

¥Nuxt Hooks (Build Time)

这些钩子可用于 Nuxt 模块 和构建上下文。

¥These hooks are available for Nuxt Modules and build context.

¥Within nuxt.config.ts

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

在 Nuxt 模块中

¥Within Nuxt Modules

应用钩子(运行时)

¥App Hooks (Runtime)

应用钩子主要用于 Nuxt 插件 钩住渲染生命周期,但也可用于 Vue 可组合组件。

¥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 */
  })
})

这些钩子可用于 服务器插件 连接到 Nitro 的运行时行为。

¥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')
  })

其他 Hooks

¥Additional Hooks

你可以通过扩充 Nuxt 提供的类型来添加其他钩子。这对于模块很有用。

¥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 'nitro/types' {
  interface NitroRuntimeHooks {
    'your-nitro-hook': () => void;
  }
}
