nuxt 需要修改的配置

css 抽离，便于 seo

 build: {
    // publicPath: '/static/',
    extractCSS: { allChunks: true }
  },

静态数据的第一次渲染使用 asyncData

asyncData 中不能使用 this

asyncData 函数中提供了 context 相当于 this

type DefaultAsyncData<V> = ((this: V, context: Context) => Promise<object | void> | object | void)

 AsyncData = DefaultAsyncData<V>

// eslint-disable-next-line @typescript-eslint/ban-types
asyncData?: AsyncData



export interface Context {
  $config: NuxtRuntimeConfig

自定义每个页面的title 和 description 等

data() {
    return {}
  },
  head() {
    return {
      title: this.title,
      meta: [
        {
          hid: 'description',
          name: 'description',
          content: 'My custom description   11111',
        },
      ],
    }
  },
  mounted() {},
