@logluarx/webpack-theme-color-replacer

基于webpack-theme-color-replacer二次开发

Install

npm i -D @logluarx/webpack-theme-color-replacer

使用

// .umirc
const getChainWebpack = require("@logluarx/webpack-theme-color-replacer/getChainWebpack");
{
  chainWebpack: getChainWebpack({
    // 需要生成一系列颜色的，比如primary-color
        seriesColors: ["#666666"],
        // 单个颜色
        matchColors: [],
        // 其他配置继承webpack-theme-color-replacer
    })
}

// app.ts入口文件，不同入口路径采用不同主题色的示例
import {userRender} from "@logluarx/webpack-theme-color-replacer/antThemeUtil";
export const render = userRender(() => { 
  const href = window.location.href;
  if (href.includes("xxx")) {
      return { 
        seriesColors: ["#666666"]
      };
  } else {
      return { seriesColors: ["#999999"] };
  }
});

// 切换控制函数
// 手动加div[data-qiankun=xxx]前缀时从antQThemeUtil导入，其他地方同理
import {updateColor} from "@logluarx/webpack-theme-color-replacer/antThemeUtil";
updateColor({
  // 系列色
  seriesColors:["#666666"],
  // antQThemeUtil时，[data-qiankun=xxx]的appName，默认查找第一个div[data-qiankun]元素的
  getAppName: ()=>"xxx"
})

update log

项目环境： 父子应用umi 2.x,antd v3，qiankun 2.x对接

1. 增加injectAhead:boolean选项，允许concat source时将代码片段接在前面； qiankun对接时从最后一个window挂载项上找lifecycle exports，接在最后会导致找不到lifecycle导出
2. themeColorChange中增加preHandleCss函数选项用于预处理cssText
3. resolve elStyle用于进行后续处理
4. 增加一些项目常用函数
5. 层级覆盖问题，从@mega-apps/webpack-theme-color-replacer的文档copy了changeSelector
6. box-shadow: rgb(xx xx xx / 20%)类型=>颜色系列中需要放"xx xx xx"

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.

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

Install

npm i -D webpack-theme-color-replacer

Cofig for webpack

const ThemeColorReplacer = require('webpack-theme-color-replacer')

module.exports = {
    // ..... other config
    plugins: [
        new ThemeColorReplacer({
            matchColors: ['#ed4040', '#4b0', '255,80,80', '27, 92.531%, 52.745%'], // colors array for extracting css file, support rgb and hsl.
            fileName: 'css/theme-colors-[contenthash:8].css', //optional. output css file name, suport [contenthash] and [hash].
            // resolveCss(resultCss) { // optional. Resolve result css code as you wish.
            //     return resultCss.replace(/#ccc/g, '#eee')
            // },
            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(selector, util) { // optional, Funciton. Changing css selectors, in order to raise css priority, to resolve lazy-loading problems.
            //     return util.changeEach(selector, '.el-button--default')
            // },
            injectCss: false, // optional. Inject css text into js file, no need to download `theme-colors-xxx.css` any more.
            isJsUgly: process.env.NODE_ENV !== 'development', // optional. Set to `true` if your js is uglified. Default is set by process.env.NODE_ENV.
            // concat resource时是否接在前面，默认true处理lifecycle找不到的问题
            injectAhead:true
        })
    ],
}

If you use customized runtime-chunk filename, it should contains a string manifest., like this:

optimization: {
  runtimeChunk: {
    name: entrypoint => 'manifest.' +  entrypoint.name,
  },
}

You can view this sample: https://github.com/hzsrc/vue-element-ui-scaffold-webpack4/blob/master/build/webpack.base.conf.js

• Other build tool(not webpack)

Otherwise, if you use other build tool(like gulp) but not webpack, you can use this plugin by nodejs:

var nodeRun = require('webpack-theme-color-replacer/src/nodeRun');
var {code, outFile} = nodeRun({
    src: 'src/css/**/*.css', // source css files. string or string array, as `glob`.
    matchColors: ['#ed4040', '#4b0', '255,80,80', '27, 92.531%, 52.745%'],
    fileName: 'css/theme-colors-[contenthash:8].css',
    // ...
})
// do sth with outFile

See this sample: https://github.com/hzsrc/webpack-theme-color-replacer/blob/master/src/nodeRun.js

Usage in your runtime web page

Like this:

import client from 'webpack-theme-color-replacer/client'

// change theme colors at runtime.
export function changeColor() {
  var options = {
    newColors: ['#f67a17', '#f67a17', '160,20,255', '285,78.182%,56.863%'], // new colors array, one-to-one corresponde with `matchColors`
    // appendToEl: 'head', //optional. The element selector for appending child with `<style>`, default is 'body'. Using `appendToEl: 'body'` can make the css priority higher than any css in <head>
    // changeUrl(cssUrl) {
    //   return `/${cssUrl}`; // while router is not `hash` mode, it needs absolute path
    // },
  }

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

You can view this sample: https://github.com/hzsrc/vue-element-ui-scaffold-webpack4/blob/master/src/js/themeColorClient.js

Options for build

These options are used for new ThemeColorReplacer(options).

* matchColors: Array<string>

Colors array for extracting css file. Css rules which have any one of these colors will be extracted out.

* fileName: string

Optional. output css file name, suport [contenthash] and [hash].

* resolveCss: Function(resultCss : string) : string

Optional. Resolve result css code as you wish.

* externalCssFiles : string | Array<string>

Optional. Set external css files (such as cdn css) to extract colors.

* changeSelector : Function(selector: string, util: { rules: Array<String>, changeEach: Function } ): string

Optional. Changing css selectors, in order to raise css priority, to resolve lazy-loading problems.

* injectCss: boolean

Optional. Inject css text into js file, no need to download theme-colors-xxx.css any more.

* isJsUgly: boolean

Optional. Default value: process.env.NODE_ENV !== 'development'. Set to true if your js is uglified. Default is set by process.env.NODE_ENV.

* configVar: string

Optional. to set custom var name, instead of theme_COLOR_cfg or tc_cfg_xxxxxx. Default is an random name which start with 'tc_cfg_'.

* injectToHtml: RegExp | true

Optional. Injecting config-code into html files instead of injecting into entry js files. Use a RegExp to check which files to be injected to. true is the same as /index\.html?$/i.

Options for runtime

These options are used for client.changer.changeColor(options), which imports client/index.js.

* newColors: Array<string>

New colors array for changing, one-to-one corresponde with matchColors.

* appendToEl: string

Optional. The element selector for this plugin to appending with child node <style>. Default is 'body'. Using appendToEl: 'body' can make the priority of theme-color-css higher than any other css in

element.

* changeUrl: Function(cssUrl: string): string

Optional. Change the theme-color-css download url if you need. While router is not hash mode, it needs to change url to an absolute path(start with /).

issues report

If you have issues with this plugin, please run your command with --theme_debug option, such as npm run dev --theme_debug, then upload the outputed _tmp_xxx files while reporting issues. Thanks!
