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 🙏

Readme

@nw-cfg/bridge

封装基于 Penpal 的 iframe RPC 连接,负责握手、来源校验、超时与重连控制。

导出能力

  • createHostBridge(iframe, { hostApi, ...options }):宿主侧建立高阶连接,返回带有 getConfigMeta/setConfig/validateConfig 等封装方法的桥接句柄,并暴露自身 hostApi 给子窗口。
  • createGuestBridge(childApi, options):子窗口注册自身 API,校验宿主暴露的方法是否完备,返回带 host 引用与 disconnect() 的句柄。
  • connectToChild(iframe, options, hostApi) / exposeChild(childApi, options):底层包装,保留对 Penpal 原始能力的直接访问。
  • validateEnvelope():辅助校验基础消息信封结构,用于低层调试。

options.timeoutMs 默认复用 DEFAULT_TIMEOUT_MSoptions.targetOrigin/parentOrigin 用于限定通信域。所有方法返回 Promise,内部基于 Penpal 的 postMessage 信道,可安全处理异步函数。
