Vite使用unplugin-auto-import实现vue3中的自动导入

unplugin-auto-import 是基于 unplugin 写的,支持 Vite、Webpack、Rollup、esbuild 多个打包工具。我们可以使用unplugin-auto-import实现依赖的自动导入,不用再频繁导入依赖包,从而提交我们的开发效率。如下,以vue3+vite中使用改插件为例。

安装

使用前我们需要先安装该依赖:

$ pnpm i unplugin-auto-import -D

配置

安装好依赖后,我们就可以在vite中配置改插件了,其在vite中的配置方法如下:

// vite.config.ts
import AutoImport from 'unplugin-auto-import/vite'

export default defineConfig({
  plugins: [
    AutoImport({
     imports: [
        'vue',
        'vue-router',
        'vue-i18n',
        '@vueuse/core',
        'pinia',
      ],
      dts: 'types/auto-imports.d.ts', // 使用typescript,需要指定生成对应的d.ts文件或者设置为true,生成默认导入d.ts文件
      dirs: ['src/stores', 'src/composables', 'src/hooks'],
    }),
  ],
})

如上就配置好了一个自动导入的插件,我们通过AutoImport插件实现了初始化导入vue、vue-router等依赖库,设置本地项目自动导入路径。其生成的声明文件如下:

/* eslint-disable */
/* prettier-ignore */
// @ts-nocheck
// noinspection JSUnusedGlobalSymbols
// Generated by unplugin-auto-import
export {}

}

使用

通过如上步骤配置好了之后,我们接下来就可以直接使用这些自动导入的依赖库了,代码如下:

// test.vue

const count = ref(0)
const doubled = computed(() => count.value * 2)

如上,我们就不需要再重新导入ref了。
