vue3 + vite 自動引入vue API以及組件

unplugin-auto-import 的使用

1. 安裝 unplugin-auto-import

• yarn add unplugin-auto-import -D

2. vite.config.ts 配置

import AutoImport from 'unplugin-auto-import/vite' //注意后面有個/vite

export default defineConfig(({ mode }: ConfigEnv): UserConfig => {
  const root = process.cwd()
  const env = loadEnv(mode, root)
  return {
    plugins: [
      AutoImport({
        imports: ['vue', 'vue-router'],
        // 可以選擇auto-import.d.ts生成的位置，使用ts建議設置為'src/auto-import.d.ts'
        dts: 'src/auto-import.d.ts'
      }),
    ]
  }
})

3. 重啟項目會在 src目錄下生成一個 auto-import.d.ts 文件

// Generated by 'unplugin-auto-import'
// We suggest you to commit this file into source control
declare global {
  const computed: typeof import('vue')['computed']
  const createApp: typeof import('vue')['createApp']
  const customRef: typeof import('vue')['customRef']
  const defineAsyncComponent: typeof import('vue')['defineAsyncComponent']
  const defineComponent: typeof import('vue')['defineComponent']
  const effectScope: typeof import('vue')['effectScope']
  const EffectScope: typeof import('vue')['EffectScope']
  const getCurrentInstance: typeof import('vue')['getCurrentInstance']
  const getCurrentScope: typeof import('vue')['getCurrentScope']
  const h: typeof import('vue')['h']
  const inject: typeof import('vue')['inject']
  const isReadonly: typeof import('vue')['isReadonly']
  const isRef: typeof import('vue')['isRef']
  const markRaw: typeof import('vue')['markRaw']
  const nextTick: typeof import('vue')['nextTick']
  const onActivated: typeof import('vue')['onActivated']
  const onBeforeMount: typeof import('vue')['onBeforeMount']
  const onBeforeUnmount: typeof import('vue')['onBeforeUnmount']
  const onBeforeUpdate: typeof import('vue')['onBeforeUpdate']
  const onDeactivated: typeof import('vue')['onDeactivated']
  const onErrorCaptured: typeof import('vue')['onErrorCaptured']
  const onMounted: typeof import('vue')['onMounted']
  const onRenderTracked: typeof import('vue')['onRenderTracked']
  const onRenderTriggered: typeof import('vue')['onRenderTriggered']
  const onScopeDispose: typeof import('vue')['onScopeDispose']
  const onServerPrefetch: typeof import('vue')['onServerPrefetch']
  const onUnmounted: typeof import('vue')['onUnmounted']
  const onUpdated: typeof import('vue')['onUpdated']
  const provide: typeof import('vue')['provide']
  const reactive: typeof import('vue')['reactive']
  const readonly: typeof import('vue')['readonly']
  const ref: typeof import('vue')['ref']
  const resolveComponent: typeof import('vue')['resolveComponent']
  const shallowReactive: typeof import('vue')['shallowReactive']
  const shallowReadonly: typeof import('vue')['shallowReadonly']
  const shallowRef: typeof import('vue')['shallowRef']
  const toRaw: typeof import('vue')['toRaw']
  const toRef: typeof import('vue')['toRef']
  const toRefs: typeof import('vue')['toRefs']
  const triggerRef: typeof import('vue')['triggerRef']
  const unref: typeof import('vue')['unref']
  const useAttrs: typeof import('vue')['useAttrs']
  const useCssModule: typeof import('vue')['useCssModule']
  const useCssVars: typeof import('vue')['useCssVars']
  const useRoute: typeof import('vue-router')['useRoute']
  const useRouter: typeof import('vue-router')['useRouter']
  const useSlots: typeof import('vue')['useSlots']
  const watch: typeof import('vue')['watch']
  const watchEffect: typeof import('vue')['watchEffect']
}
export {}

4. 在組件中不必導入方法便可以直接使用

const upload = ref<any>()

unplugin-vue-components 的使用

1. 安裝 unplugin-vue-components

• yarn add unplugin-vue-components -D

2. vite.config.ts 配置

import Components from 'unplugin-vue-components/vite' //注意后面有個/vite

export default defineConfig(({ mode }: ConfigEnv): UserConfig => {
  const root = process.cwd()
  const env = loadEnv(mode, root)
  return {
    plugins: [
      Components({
        dirs: ['src/components'],
        extensions: ['vue', 'tsx'],
        // 配置文件生成位置
        dts: 'src/components.d.ts'
      })
    ]
  }
})

3. 重啟項目會在 src 目錄下生成 components.d.ts

4. 同上組件可以在頁面直接使用
