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 🙏

Yunzai NG 模板用 JSX 运行时(字符串直出,无虚拟 DOM)

Readme

@yunzai-ng/jsx

给写渲染模板的人的一个可选 JSX 运行时。产出 HTML 字符串,不涉及浏览器。

为什么不是 core 的一个子路径

分层门禁把 @yunzai-ng/core/* 的任意子路径判为「深引内核内部实现」。为一个 JSX 运行时给门禁 开洞不划算;独立成包之后,第三方插件也能只依赖它而不牵入整个内核。

用法

在插件的 tsconfig.json 里指向它:

{
  "compilerOptions": {
    "jsx": "react-jsx",
    "jsxImportSource": "@yunzai-ng/jsx"
  }
}

然后模板就是一个函数:

import { Html, cx } from "@yunzai-ng/jsx"

export function Profile({ name, level }: { name: string; level: number }) {
  return (
    <Html title={name}>
      <div class={cx("card", level >= 60 && "card-max")}>
        <h1>{name}</h1>
        <p>等级 {level}</p>
      </div>
    </Html>
  )
}

把它的返回值交给 ctx.render()

两处要注意

默认转义。 插进去的值一律转义,故用户昵称里的 <script> 不会变成脚本。确实要插入原始 HTML 时用 raw() —— 它显眼,便于审阅时逐个确认。

cx()style() 是为条件拼接准备的。 手写 class={"a " + (b ? "c" : "")} 会在条件为假时 留下一个尾随空格,而某些工具类框架对空 class 的处理并不一致。
