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 🙏

@botlearn-course/courseware-bridge

v0.1.1

Published

Versioned bridge contract and injected runtime for BotLearn sandboxed courseware.

Readme

@botlearn-course/courseware-bridge

BotLearn sandboxed courseware iframe 与宿主之间的共享 V1 contract、运行时校验和注入 SDK。

平台或工具链安装:

pnpm add @botlearn-course/courseware-bridge

课件作者怎么接入

课程 HTML 不需要安装依赖。平台渲染 iframe 时会自动注入 SDK;作者应优先使用声明式属性:

<button type="button" data-botlearn-practice-action="open">
  回到练习场预览
</button>

<button type="button" data-botlearn-content-action="learning.advance">
  进入下一节
</button>

只有声明式 DOM 无法表达的复杂交互,才调用注入的受限 API:

await window.botlearnCoursewareBridge.ready()
if (window.botlearnCoursewareBridge.supports('learning.advance')) {
  await window.botlearnCoursewareBridge.request('learning.advance', {})
}

不得在课程 HTML 中直接调用 parent.postMessage,也不得手写 wire envelope。提交审核、发布和 后台“校验课程定义”都会执行相同的发布前检查。

平台开发者看哪里

  • protocol-v1.json:跨语言机器可读 contract,也是 Python 发布校验器的 parity fixture。
  • src/protocol.ts:TypeScript 类型、envelope 与 payload 校验。
  • src/runtime-script.ts:注入 iframe 的 SDK 构建器。
  • docs/specs/courseware-bridge-protocol.md:完整语义、消息矩阵、安全和兼容策略。

修改 contract 后必须同时更新 fixture、TypeScript 校验、Python 发布校验及其测试。
