vue3+vite插件配置系列2-unplugin-auto-import

作用

解放双手，自动导入composition api 和 生成全局typescript说明

使用

1.下载

npm i -D unplugin-auto-import

2.vite.config.ts配置

import AutoImport from "unplugin-auto-import/vite"
export default defineConfig({
  plugins: [
    ...
     AutoImport ({
      imports: ["vue", "vue-router"], // 自动导入vue和vue-router相关函数
      dts: "src/auto-import.d.ts" // 生成 `auto-import.d.ts` 全局声明
    })
  ]
})

3.现在vue组件中可以直接使用composition api

before

<template>
  <button @click="add">add</button>
  <button @click="routerPush">go</button>
  {{count}}
</template>

<script lang="ts" setup>
import { ref } from 'vue'
import { useRouter } from 'vue-router'
const count = ref(0)
const router = useRouter()
function add() {
  count.value++
}
function routerPush(){
	router.push('a')
}
</script>

after

<template>
  <button @click="add">add</button>
  <button @click="routerPush">go</button>
  {{count}}
</template>

<script lang="ts" setup>
const count = ref(0)
const router = useRouter()
function add() {
  count.value++
}
function routerPush(){
	router.push('a')
}
</script>
