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 🙏

@moluoxixi/postcss-selector-prefix

v0.0.2

Published

基于 `postcss-selector-parser` 的 PostCSS 插件,用于精确替换 class 与 id 选择器的名称前缀。 插件会替换 selector AST 中的 class/id 节点、`class`/`id` 属性选择器的值, 以及 CSS 值里能表达 selector 的文本片段; 不会改写 `url(...)` 这类资源路径,也不会碰 HTML 或 JS 字符串。

Vite 使用

import { createSelectorPrefixPlugin } from '@moluoxixi/postcss-selector-prefix'
import { defineConfig } from 'vite'

export default defineConfig({
  css: {
    postcss: {
      plugins: [
        createSelectorPrefixPlugin({
          fromPrefix: 'el-',
          toPrefix: 'moluoxixi-',
        }),
      ],
    },
  },
})

以上配置会将 .el-button#el-app[class^="el-"][id="el-app"] 以及 content: '.el-button #el-app'@supports selector(.el-button) 里的 selector 文本改写为对应的 moluoxixi 前缀;url(".el-button.svg") 仍会保持原样。
