构建工具采用Vite

CSS预处理器采用Sass

一.准备定制化的样式文件

1.安装Sass

npm i sass -D

2.创建好文件目录

3.书写样式

ElementPlus默认样式.

//index.scss

/* 只需要重写你需要的即可 */
@forward 'element-plus/theme-chalk/src/common/var.scss' with (
  $colors: (
    'primary': (
      // 主色
      'base': #27ba9b,
    ),
    'success': (
      // 成功色
      'base': #1dc779,
    ),
    'warning': (
      // 警告色
      'base': #ffb302,
    ),
    'danger': (
      // 危险色
      'base': #e26237,
    ),
    'error': (
      // 错误色
      'base': #cf4444,
    ),
  )
)

二.自动导入配置

1.配置Vite.config.js

npm install unplugin-element-plus/vite

在Vite.config.js中

import { fileURLToPath, URL } from 'node:url'
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
//按需引入样式
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
// 导入对应包
import ElementPlus from 'unplugin-element-plus/vite'
export default defineConfig({
  plugins: [
    vue(),
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [ElementPlusResolver()],
    }),
    // 按需定制主题配置
    ElementPlus({
      useSource: true,
    }),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  },
  css: {
    preprocessorOptions: {
      scss: {
        // 自动导入定制化样式文件进行样式覆盖
        additionalData: `
          @use "@/styles/element/index.scss" as *;
        `,
      }
    }
  }
})
