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 🙏

Static Plugin graph, generation transaction and HMR Root runtime for Zhin.js

Readme

@zhin.js/runtime

Zhin.js Plugin 树的 Root 生命周期权威。它从静态 package manifest 构建 Plugin instance tree,按 owner 组合 schema/config/env,通过 Feature provider 发现 capability,并用 immutable snapshot、CAS generation 与 lease 驱动局部 HMR。

import { EsmModuleRuntime, RootRuntime } from '@zhin.js/runtime';

const runtime = new RootRuntime({
  projectRoot: process.cwd(),
  modules: new EsmModuleRuntime(),
  environment: { mode: 'development' },
});

await runtime.start();

事务边界

  • capability 文件变化只 prepare 对应 Slot。
  • child/schema 变化替换最浅受影响 subtree。
  • manifest topology transaction 支持 child/Feature 新增、删除和移动。
  • Root/package ABI、lockfile 和未知 importer 变化升级为 process restart。
  • 候选校验或 handoff 失败不提交 generation;旧 snapshot 保持可用。
  • 最后一个旧 lease 释放后,旧资源才按 children-first 顺序回收。

Runtime 不静态导入 Command、Agent、Page 或 Adapter provider。具体能力由插件 manifest 动态装配。Ajv 用于整树 schema 校验,semver 用于 engine/Feature API admission;它们只 属于显式安装的 Root 控制面,不进入 zhin.js 默认 IM 安装。

zhin.js/runtime 是指向本包的 optional-peer facade。新项目应显式安装本包;这保证 zhin.js 默认 IM 闭包继续满足 10MB 门禁。
