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 🙏

API

GlobalStyles

全局样式组件。

Props:

| 属性 | 说明 | 类型 | 默认值 | | ------------------ | -------------------- | --------- | ------ | | theme | 主题对象 | Theme | - | | enableReset | 是否启用全局样式重置 | boolean | true | | enableCSSVariables | 是否启用 CSS 变量 | boolean | true |

themeToCSSVariables

将主题对象转换为 CSS 变量对象。

import { themeToCSSVariables } from '@l2ui/styles';

const vars = themeToCSSVariables(defaultTheme);
// { '--l2ui-color-primary': '#1890ff', ... }

generateCSSVariables

生成 CSS 变量样式字符串。

import { generateCSSVariables } from '@l2ui/styles';

const css = generateCSSVariables(defaultTheme);
// ':root {\n  --l2ui-color-primary: #1890ff;\n  ...\n}'

最佳实践

  1. 使用主题 Provider:始终使用 ThemeProvider 包裹应用
  2. 启用全局样式:在应用根组件使用 GlobalStyles
  3. 使用 CSS 变量:在自定义样式时优先使用 CSS 变量
  4. 主题切换:通过切换 ThemeProvider 的 theme 属性实现主题切换

示例

主题切换

import { useState } from 'react';
import { ThemeProvider } from 'styled-components';
import { defaultTheme, darkTheme, GlobalStyles } from '@l2ui/styles';

function App() {
  const [isDark, setIsDark] = useState(false);
  const theme = isDark ? darkTheme : defaultTheme;

  return (
    <ThemeProvider theme={theme}>
      <GlobalStyles theme={theme} />
      <button onClick={() => setIsDark(!isDark)}>切换到{isDark ? '亮色' : '暗色'}主题</button>
      {/* 你的应用 */}
    </ThemeProvider>
  );
}
