在svelet5中导入并使用react组件库

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)

└  You're all set!

$ cd my-svelte-react

$ pnpm install

$ pnpm dev

1. 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

1. 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
});

1. 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

1. 添加react组件库, 如 [ant design](https://github.com/ant-design/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>
