svelte5中使用react组件

在svelet5中导入并使用react组件库, 示例项目地址：https://github.com/shenshouer/my-svelte-react

在svelte5中当前还有问题，无法将children传递到react中渲染

1. 使用svletkit创建项目

$ npx sv create my-svelte-react% npx sv create my-svelte-react
┌  Welcome to the Svelte CLI! (v0.6.10)
│
◇  Which template would you like?

│  1: cd my-svelte-react                                                   │
│  2: git init && git add -A && git commit -m "Initial commit" (optional)  │
│  3: pnpm run dev --open                                                  │
│                                                                          │
│  To close the dev server, hit Ctrl-C                                     │

└  You're all set!$ cd my-svelte-react$ pnpm install$ pnpm dev

2. 安装react相关依赖

$ pnpm i react react-dom
$ pnpm i --save-dev @types/react @types/react-dom
$ pnpm add @vitejs/plugin-react -D

3. 修改vite.config.ts增加react支持

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';  # <---- hereexport default defineConfig({plugins: [sveltekit(), react()]        # <---- here
});

4. 创建react svelte适配器ReactAdapter.svelte, 代码如下:

# src/lib/utils/ReactAdapter.svelte<script lang="ts">import React from "react";import ReactDOM from "react-dom/client";import { onDestroy, onMount } from "svelte";const e = React.createElement;let container: HTMLElement;let root: ReactDOM.Root;onMount(() => {const { el, children, class: _, ...props } = $$props;try {root = ReactDOM.createRoot(container);root.render(e(el, props, children));} catch (err) {console.warn(`react-adapter failed to mount.`, { err });}});onDestroy(() => {try {if (root) {root.unmount();}} catch (err) {console.warn(`react-adapter failed to unmount.`, { err });}});
</script><div bind:this={container} class={$$props.class}></div>

目前此部分适配器有问题, children无法获取并且在react组件中渲染

参考：
props-and-restProps
issues

5. 添加react组件库, 如 ant design

$ pnpm add antd# +page.svelte<script lang="ts">import { Button } from "antd";import ReactAdapter from "$lib/utils/ReactAdapter.svelte";
</script><ReactAdapter el={Button} type="primary">Hello, World!</ReactAdapter>
