1、安装pnpm

npm install pnpm -g

2、开始创建vite项目

pnpm create vite

按照步骤创建项目名称、选择框架

cd vue3-vite-project

vue-router

pnpm install vue-router@4

vuex

pnpm add vuex@next

安装UI库naive-ui

pnpm add naive-ui

Naive UI

安装axios

pnpm add axios

安装 mock 工具

pnpm add mockjs pnpm add vite-plugin-mock -D

安装自定义组件自动导入

unplugin-vue-components

pnpm install unplugin-vue-components -D

Vite配置

// vite.config.js
import { defineConfig } from 'vite'
import Components from 'unplugin-vue-components/vite'
import {
  ElementPlusResolver,
  AntDesignVueResolver,
  VantResolver,
  HeadlessUiResolver,
  ElementUiResolver,
  NaiveUiResolver

} from 'unplugin-vue-components/resolvers'

export default defineConfig({
  plugins: [
    Components({
      // ui库解析器，也可以自定义
      resolvers: [
        ElementPlusResolver(),
        AntDesignVueResolver(),
        VantResolver(),
        HeadlessUiResolver(),
        ElementUiResolver(),
?        NaiveUiResolver()      

?       ]
?    })
  ]
})

安装 unplugin-auto-import

?pnpm i -D unplugin-auto-import

自动导入vue3的hooks，借助unplugin-auto-import/vite这个插件

支持vue, vue-router, vue-i18n, @vueuse/head, @vueuse/core等自动引入

先看效果图

// 引入前
import { ref, computed } from 'vue'
const count = ref(0)
const doubled = computed(() => count.value * 2)

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


// 引入前
import { useState } from 'react'
export function Counter() {
  const [count, setCount] = useState(0)
  return <div>{ count }</div>
}

//引入后
export function Counter() {
  const [count, setCount] = useState(0)
  return <div>{ count }</div>
}

安装 vite-auto-import-resolvers

pnpm i vite-auto-import-resolvers unplugin-auto-import -D

unplugin-auto-import 的 vite resolvers，主要处理 vite 项目本身的 api 按需自动引入。

按需自动引入指定目录下模块的 api。

配置插件

// vite.config.js
// 或者 vite.config.ts

import { defineConfig } from 'vite'
import Vue from '@vitejs/plugin-vue'
import AutoImports from 'unplugin-auto-import/vite'
import { dirResolver, DirResolverHelper } from 'vite-auto-import-resolvers'

export default defineConfig({
    plugins: [
        Vue(),
        // 该辅助插件也是必需的 👇
        DirResolverHelper(),
        AutoImports({
            imports: ['vue'],
            resolvers: [
                dirResolver()
            ]
        })
    ]
})

配置index.ts

import type { Plugin } from 'vite';

import { NaiveUiResolver } from 'unplugin-vue-components/resolvers';

export function createVitePlugins(viteEnv: ViteEnv, isBuild: boolean, prodMock) {
  const { VITE_USE_MOCK, VITE_BUILD_COMPRESS, VITE_BUILD_COMPRESS_DELETE_ORIGIN_FILE } = viteEnv;

  const vitePlugins: (Plugin | Plugin[])[] = [
    // have to
    vue(),
    // have to
    vueJsx(),
    AutoImport({
      // imports: ['vue', 'vue-router', 'vue-i18n', '@vueuse/head'],
      imports: AutoGenerateImports(), // 自动管理，只有对应的包有装时才会自动按需设置预设
      // 可以选择auto-import.d.ts生成的位置，使用ts建议设置为'src/auto-import.d.ts'
      // dts: 'src/auto-import.d.ts'
      resolvers: [
        // dirResolver({ prefix: 'use' }), // 强制前缀为 use
        dirResolver(),
      ],
    }),
    // 按需引入NaiveUi且自动创建组件声明
    Components({
      // dts: true,
      resolvers: [NaiveUiResolver()],
      // 指定组件位置，默认是src/components
      dirs: ['src/components'],
      // ui库解析器
      // resolvers: [ElementPlusResolver()],
      extensions: ['vue'],
      // 配置文件生成位置
      dts: 'src/components.d.ts',
    }),
  ];

  // vite-plugin-html
  vitePlugins.push(configHtmlPlugin(viteEnv, isBuild));

  // vite-plugin-mock
  VITE_USE_MOCK && vitePlugins.push(configMockPlugin(isBuild, prodMock));

  if (isBuild) {
    // rollup-plugin-gzip
    vitePlugins.push(
      configCompressPlugin(VITE_BUILD_COMPRESS, VITE_BUILD_COMPRESS_DELETE_ORIGIN_FILE)
    );
  }

  return vitePlugins;
