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?
   │ SvelteKit minimal
   │
   ◇ Add type checking with Typescript?
   │ Yes, using Typescript syntax
   │
   ◆ Project created
   │
   ◇ What would you like to add to your project? (use arrow keys / space bar)
   │ none
   │
   ◇ Which package manager do you want to install dependencies with?
   │ pnpm
   │
   ◆ Successfully installed dependencies

   ◇ Project next steps ─────────────────────────────────────────────────────╮

   │ 1: cd my-svelte-react │
   │ 2: git init && git add -A && git commit -m "Initial commit" (optional) │

   ├──────────────────────────────────────────────────────────────────────────╯
   │
   └ 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'; # <---- here

   export 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>

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>
