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 🙏

class-css

v1.0.29

Published

A css-in-js library, which make your work interesting and easily!

Readme

class-css

一个 css-in-js 库, 可用于样式局域化,以及通过 js 控制样式。

Quick Start

运行一个简单的示例程序。

import { css } from "class-css";
import React, { useState } from "react";

export default () => {
  const [color, setColor] = useState("black");
  return (
    <div>
      <div>
        <button onClick={() => setColor("red")}>红色</button>
        <button onClick={() => setColor("blue")}>蓝色</button>
      </div>
      <div className={css({ color })}>测试文字</div>
    </div>
  );
};

Use In Project

在项目中使用。

In React.

import React from "react";
import { css } from "class-css";

export default () => {
  return <div className={css({ color: "red" })}>一段文字</div>;
};

In Vue.

<template>
  <div :class="css({ color: 'red' })">一段文字</div>
</template>

<script setup>
  import { css } from 'class-css';
</script>

Compare with @emotion/css ?

class-css 能比 @emotion/css 创建更少的dom节点。

@emotion/css 调用 css 方法时,如果不存在于缓存中,则不断创建 style 标签。

class-css,仅会在全局创建唯一 style 标签,并采用增量添加的形式添加新的样式文本到 style 标签中。

Why use css-in-js library?

  • 实现 style 不支持的功能,例如:伪选择器(:hover)等。
  • 方便替换主题色。
  • 局域样式,不影响全局样式。
  • 可以通过类名进行全局覆盖 css-in-js 样式。
  • 无需加载额外的 css 文件
