Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

神奇代码岛 React-UI

适用于 神岛 Arena 客户端 UI 的 React 渲染器,基于官方 React 18 渲染器实现。

参考文档:

React 18 官网:https://18.react.dev/

神岛react-ui详细教程:https://docs.box3lab.com/arenapro/zh/react/

安装

npm install @dao3fun/react-ui

导出结构:

  • @dao3fun/react-ui
    内置 UI 元素组件(BoxTextImageInputScrollBox 等)
  • @dao3fun/react-ui/dom
    渲染入口(createRoot 等)
  • @dao3fun/react-ui/hooks
    与神岛客户端交互的常用 Hook(useScreenSizeuseClientRemoteChannel 等)

快速上手

import React, { useState } from 'react';
import { Box, Text } from '@dao3fun/react-ui';
import { createRoot } from '@dao3fun/react-ui/dom';

function App() {
  const [count, setCount] = useState(0);

  return (
    <Box onClick={() => setCount((c: number) => c + 1)}>
      <Text>你好,React!你点我了 {count} 次</Text>
    </Box>
  );
}

// ui 由神岛客户端提供,对应根 UI 节点
const root = createRoot(ui);
root.render(<App />);

内置元素组件(Intrinsic Elements)

这些组件会通过自定义渲染器映射到对应的 神岛 UI 元素:

  • Box:基础容器
  • Text:文本显示(children 会自动映射到底层的 textContent
  • Image:图片元素(支持 onLoad 等事件)
  • Input:输入框(支持 onFocus / onBlur / onChange 等事件)
  • ScrollBox:可滚动容器

示例:

import { Box, Text, Image, Input, ScrollBox } from '@dao3fun/react-ui';

神岛特有 Hooks

通过 @dao3fun/react-ui/hooks 提供了一些与宿主环境交互的 Hook:

  • useScreenSize()
    监听屏幕尺寸变化,返回 { screenWidth, screenHeight }

  • useClientRemoteChannel<T>()
    客户端 <-> 服务端通信:

    type ServerEvent =
      | { type: 'chat'; message: string }
      | { type: 'system'; code: number };
    
    const { lastEvent, send } = useClientRemoteChannel<ServerEvent>();
  • usePointerLock()
    监听并控制指针锁定状态:

    const { isLocked, errorCount, lockPointer, unlockPointer } = usePointerLock();
  • useAudio(src)
    客户端 Audio,提供状态机:

    const { audio, status } = useAudio('https://.../bgm.mp3');

TypeScript 支持

该包基于 TypeScript 编写,并提供完整的类型信息:

  • 组件 props 里会自动推导底层 UiBox / UiText / UiInput / UiImage / UiScrollBox 类型
  • 事件参数类型为 UiEvent<T>,可以获得更好的开发体验

在你的项目Client中开启 JSX 支持:

// client/tsconfig.json
{
  "compilerOptions": {
    "jsx": "react",
  },
}

注意事项

  • 仅适用于神岛 Arena 提供的 UI 运行环境,不能 在普通浏览器或 Node 环境中直接渲染 DOM
