在项目中该如何配置，使得vite的模块联邦打包出来的js转为es5?

Versions

• originjs:
• node:

Reproduction

import { defineConfig } from "vite"; import vue from "@vitejs/plugin-vue"; import Components from 'unplugin-vue-components/vite'; import { VantResolver } from 'unplugin-vue-components/resolvers'; import federation from "@originjs/vite-plugin-federation"; import path from "path"; import legacy from "@vitejs/plugin-legacy"; import { serverUrlMap, burialUrlMap,channelIdMap } from "./src/utils/config"; import { viteVConsole } from "vite-plugin-vconsole";

// https://vitejs.dev/config/ export default defineConfig({ plugins: [ legacy({}), vue(), Components({ resolvers: [VantResolver()], }), federation({ name: "router-remote", filename: "remoteEntry.js", exposes: { "./ElementPlus": "./src/views/oss.vue" }, shared: ["vue", "vue-router", "vuex", "vant"] }) ], build:{ target:"esnext", rollupOptions:{ // https://rollupjs.org/guide/en/#big-list-of-options output:{ manualChunks(id) { if (id.includes('node_modules')) { return 'vendor'; } } } }, }, });

Steps to reproduce

What is Expected?

打包出来的js格式是es5

What is actually happening?

打包报错 No corresponding legacy polyfill chunk found

I'm afraid that it's not supported yet. If we use the ESM format by default, it will depend to the top-level await feature, so we have to set the target:'esnext'.

export default defineConfig({
  build: {
	target: 'esnext',
  }
})

But you can also try the system format, which I have not tried.
