element修改默认主题颜色

element有一套默认的颜色,我们可以根据需求去配置
1.前置
首先elementplus和自动导入插件要配置好
npm i elementPlus
npm install -D unplugin-vue-components unplugin-auto-import
且在vite.config.js里配置好

import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'


export default defineConfig({
  plugins: [
    // 配置插件
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [ElementPlusResolver()],
    }),
  ]
})

2.创建自定义主题颜色文件,统一在src\styles\element\index.scss中

@forward 'element-plus/theme-chalk/src/common/var.scss' with (
  $colors: (
    'primary': (
      // 主色
      'base': #1b8d74,
    ),
    'success': (
      // 成功色
      'base': #1dc779,
    ),
    'warning': (
      // 警告色
      'base': #ffb302,
    ),
    'danger': (
      // 危险色
      'base': #e26237,
    ),
    'error': (
      // 错误色
      'base': #cf4444,
    ),
  ),
);

3.确认在main.js中有如下配置

import './assets/main.css'
// import './styles/element/index.scss'
import { createApp } from 'vue'
import { createPinia } from 'pinia'

import ElementPlus from 'element-plus'
import App from './App.vue'
import router from './router'

const app = createApp(App)

app.use(createPinia())
app.use(router)
app.use(ElementPlus)
app.mount('#app')

4.在vite.config.js中进行scss的默认替换

import { fileURLToPath, URL } from 'node:url'
import path from 'path'
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
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'

// https://vitejs.dev/config/
export default defineConfig({

  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 *;
        `,
      }
    }
  },
  plugins: [
    vue(),
    AutoImport({
      resolvers: [ElementPlusResolver()],
    }),
    Components({
      resolvers: [
//特别注意importStyle不要搞错啦
        ElementPlusResolver({importStyle : "sass"})
      ],
    }),
    // 按需定制主题配置
    ElementPlus({
      useSource: true,
    }),
  ],
})
