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 🙏

Readme

核心代码来源https://github.com/hzsrc/webpack-theme-color-replacer,在此基础上支持对特定变量的替换,比如var(--search-bar-background-color);对提取的样式做了js封装,以便跨域或者离线情况下获取皮肤样式,同时也将样式文件写入了入口文件,可以避免异步获取皮肤样式的开销。

This plugin can extract theme color styles from all the outputed css files (such as element-ui theme colors), and make a 'theme-colors.css' file which only contains color styles. At runtime in your web page, the client part will help you to download this css file, and then replace the colors into new customized colors dynamicly.

This is a sample: https://hzsrc-vue-webpack4-elementui.netlify.com/themeColor.html

Implementation (Chinese): https://segmentfault.com/a/1190000016061608

1.Install

npm i -D webpack-skin-changer

2.Cofig for webpack


const ThemeColorReplacer = require('webpack-skin-changer')

module.exports = {
    .....
    plugins: [
        new ThemeColorReplacer({
			fileName: 'js/theme-colors-[contenthash:8].js', // output css file name, suport [contenthash] and [hash].
            matchColors: ['var(--search-bar-background-color)', '#4b0'], // colors array for extracting css file
            resolveCss(resultCss) { // optional. Resolve result css code as you wish.
                return resultCss.replace(/#4b0/g, '#ed4040')
            },
            externalCssFiles: ['./node_modules/element-ui/lib/theme-chalk/index.css'], // optional, String or string array. Set external css files (such as cdn css) to extract colors.
            changeSelector(cssSelector) { // optional, Funciton. Changing css selectors, in order to raise css priority, to resolve lazy-loading problems.
                return cssSelector
            },
            isJsUgly: process.env.NODE_ENV !== 'development', // optional. Set to `true` if your js is uglified. Default is set by process.env.NODE_ENV.
        })
    ],
}

3.Usage in your web page

Like this:

import replacer from 'webpack-skin-changer/client'

// change theme colors at runtime.
export function changeColor(newColor) {
  var options = {
    newColors: [newColor, newColor], // new colors array, one-to-one corresponde with `matchColors`
    // changeUrl(cssUrl) {
    //   return `/${cssUrl}`; // while router is not `hash` mode, it needs absolute path
    // },
  }

  replacer.changer.changeColor(options, Promise).then(() => {
      console.log('Theme colors changed!')
  })
}
