求救啊，公司app内嵌的h5项目
打包太大怎么优化啊？

// vite.config.js
import { fileURLToPath, URL } from 'node:url'

import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import vueJsx from '@vitejs/plugin-vue-jsx'
import ElementPlus from 'unplugin-element-plus/vite'
import Components from 'unplugin-vue-components/vite'
import legacy from '@vitejs/plugin-legacy'
import terser from '@rollup/plugin-terser'
import path from 'path'
import { createSvgIconsPlugin } from 'vite-plugin-svg-icons'

export default defineConfig({
  esbuild: {
    target: 'es2015'
  },
  plugins: [
    legacy({
      targets: ['chrome >= 50'],
      renderLegacyChunks: true,
      modernPolyfills: true
    }),
    vue(),
    createSvgIconsPlugin({
      iconDirs: [path.resolve(process.cwd(), 'src/assets/icons')],
      symbolId: 'icon-[name]'
    }),
    vueJsx(),
    ElementPlus(),
    Components({
      resolvers: [
        (componentName) => {
          if (componentName.startsWith('Icon')) {
            return { name: componentName.slice(4), from: '@icon-park/vue-next' }
          }
        }
      ]
    })
  ],
  css: {
    preprocessorOptions: {
      scss: {
        additionalData: `@import "@/assets/sass/my_color_var";`
      }
    }
  },
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url)),
      'vue-i18n': 'vue-i18n/dist/vue-i18n.cjs.js'
    }
  },
  build: {
    targets: ['chrome >= 50'],
    rollupOptions: {
      plugins: [
        terser({
          compress: {
            drop_console: true
          }
        })
      ],
      output: {
        manualChunks(id) {
          if (id.includes('node_modules')) {
            return 'vendor'
          }
        }
      }
    }
  },
  base: './',
  server: {
    port: 2225,
    host: true
  }
})

这是我现在的vite.config.js
