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 🙏

webpack-qc-iconfont-plugin

webpack-qc-iconfont-plugin是一个webpack插件,可以轻松地帮你将阿里icon的图标项目下载至本地

Install

$ npm install webpack-qc-iconfont-plugin

Usage

  • webpack.config.js 文件:
const Path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
const webpack = require('webpack');

// 引入插件
const WebpackQcIconfontPlugin = require('iconfont-webpack-plugin')

module.exports = {
  mode: 'development',
  entry: './test/index.js',
  devtool: 'inline-source-map',
  devServer: {
    contentBase: './dist',
    hot: true
  },
  plugins: [
    new CleanWebpackPlugin(),
    new HtmlWebpackPlugin({
      title: 'Hot Module Replacement'
    }),
    new webpack.NamedModulesPlugin(),
    new webpack.HotModuleReplacementPlugin(),

    // 插件调用代码
    new WebpackQcIconfontPlugin({
      url: '//at.alicdn.com/t/font_xxxxxxx_xxxxxx.css',
      isDev: true,
     fontPath: './iconfont/iconfont',
     iconPrefix: '.cu-icon-',
     keepIconFontStyle: false,
     fontExt: ['.eot', '.ttf', '.svg', '.woff', '.woff2'],
     template: 'index.html'
    }),
  ],
  output: {
    filename: '[name].bundle.js',
    path: Path.resolve(__dirname, 'dist')
  }
};

Options

  • url

    • 类型:String
    • 默认:无,该参数是必须(没有将会报错)
    • 描述:为阿里图标中 - 我的图标项目 - 中获取的css代码url
    • 基础用法:new WebpackQcIconfontPlugin({url: '//at.alicdn.com/t/font_xxxxxxx_xxxxxx.css' })
  • isDev

    • 类型:String,
    • 默认:true
    • 描述:当前是否为开发模式
  • fontPath

    • 类型:String
    • 默认:'./iconfont/iconfont'
    • 描述:下载的字体图标文件保存路径,只有在 isDev 为false,也就是生产环境才有效
  • iconPrefix

    • 类型:String
    • 默认:与源文件保持一致 .icon-
    • 描述:字体图标统一前缀,如设置为 { iconPrefix: '.cu-icon-' },则图标调用为:<i class="iconfont cu-icon-XXX"></i>
  • keepIconFontStyle

    • 类型:Boolean
    • 默认:undefined,即未开启,不保留
    • 描述:是否保留css源文件中的 .iconfont{/*...*/} 中的样式,该属性多用于与vant等类似已有自己字体图标相关初始设置的组件库配合使用,如您没有与类似组件使用,建议开启或自定义一个,否则您的图标将不会有初始样式
  • fontExt

    • 类型:Array
    • 默认:['.eot', '.ttf', '.svg', '.woff', '.woff2'] ,即全部下载
    • 描述:需要下载的字体图标格式扩展名,只有在 isDev 为false时有效
  • template

    • 类型:String
    • 默认:index.html
    • 描述:生成的图标css将自动注入模板文件,图标生成后会根据该配置自动注入到模板文件中,无需手动调用,如不需要自动注入,可以将该值设置为 null
    • 补充:开发模式下会css会以 <style> ... </style> 形式注入,生成模式下会以 <link rel="stylesheet" href="./iconfont.css"> 方式注入

开发模式(基础用法):

将自动获取css源文件注入到定义的模板中。

webpack.config.js

const WebpackQcIconfontPlugin = require('iconfont-webpack-plugin')

module.exports = {
  plugins: [
    new WebpackQcIconfontPlugin({ url: '//at.alicdn.com/t/font_xxxxxxx_xxxxxx.css' })
  ]
}

Output:

将在 index.html 文件夹下以 <style> ... </style> 形式注入css,注入css结构如下:

@font-face {font-family: "iconfont";
  src: url('//at.alicdn.com/t/font_xxxxxxx_xxxxxx.eot?t=xxx');
  src: url('//at.alicdn.com/t/font_xxxxxxx_xxxxxx.eot?t=xxx#iefix') format('embedded-opentype'),
  url('data:application/x-font-woff2;charset=utf-8;base64,d09GMgA...') format('woff2'),
  url('//at.alicdn.com/t/font_xxxxxxx_xxxxxx.woff?t=xxx') format('woff'),
  url('//at.alicdn.com/t/font_xxxxxxx_xxxxxx.ttf?t=xxx') format('truetype'),
  url('//at.alicdn.com/t/font_xxxxxxx_xxxxxx.svg?t=xxx#iconfont') format('svg');
}
.icon-waimai1:before {
  content: "\e6c3";
}

非开发模式下:

  1. 将自动获取css源文件保存至 fontPath 配置路径下,并将图标引用路径自动更改为 fontPath 本地路径。
  2. 将自动获取字体图标需要的文件保存至指定位置下的 fontPath 路径中。

webpack.config.js

const WebpackQcIconfontPlugin = require('iconfont-webpack-plugin')

module.exports = {
  plugins: [
    new WebpackQcIconfontPlugin({
      url: '//at.alicdn.com/t/font_xxxxxxx_xxxxxx.css',
      isDev: false,
      iconPrefix: '.cu-icon-'
    })
  ]
}

Output:

将在配置的输出文件下输出字体图标文件(这里我们以dist文件夹为例):

- dist
  - iconfont
    - iconfont.eot
    - iconfont.ttf
    - iconfont.svg
    - iconfont.woff
    - iconfont.woff2
  - iconfont.css

iconfont.css 生成结构如下:

@font-face {font-family: "iconfont";
  src: url('./iconfont/iconfont.eot?t=xxx'); /* IE9 */
  src: url('./iconfont/iconfont.eot?t=xxx#iefix') format('embedded-opentype'), /* IE6-IE8 */
  url('data:application/x-font-woff2;charset=utf-8;base64,d09GMgA...') format('woff2'),
  url('./iconfont/iconfont.woff?t=xxx') format('woff'),
  url('./iconfont/iconfont.ttf?t=xxx') format('truetype'), /* chrome, firefox, opera, Safari, Android, iOS 4.2+ */
  url('./iconfont/iconfont.svg?t=xxx#iconfont') format('svg'); /* iOS 4.1- */
}
.cu-icon-waimai1:before {
  content: "\e6c3";
}

index.html 模板文件下head将自动引入该css:

<head>
  <meta charset="UTF-8">
  <title>WebpackQcIconfontPlugin Template</title>
  <link rel="stylesheet" href="./iconfont.css">
</head>

Events

插件开发时预留了两个事件,以便开发人员可以更个性化的使用,在阅读事件用法的时候,请确保您具备编写简单 Webpack Plugin 的能力,以及对 Tapable 有初步的认识。

  • iconfontCssCreateEnd hook

    • hook类型: AsyncParallelHook

    • 描述:字体文件css创建结束后调用。hook注册时将接收以下参数:

      • arg1: result 创建的图标css文件字符串
      • arg2: callback 回调函数,该函数可接受再次处理后的 result,便于您对css文件进行压缩,合并等处理,当然您还可以不传入 result,这时插件将不会再把生成的css文件加入到输出资源列表中,该资源就成为您的盘中餐,可以为所欲为了。
    • 示例一:利用回调函数返回处理后的css,为其添加css代码

    WebpackQcIconfontPlugin.getHooks.for('iconfontCssCreateEnd').tapAsync('MyPlugin', (result, cb) => {
      result += '.test { width: 500px; }';
      cb(result);
    })
    • 示例二:利用回调函数不返回值,自定义输出资源路径及名字
    WebpackQcIconfontPlugin.getHooks.for('iconfontCssCreateEnd').tapAsync('MyPlugin', (result, cb) => {
      compilation.assets['css/myIconFont.css'] = {
        source: function () {
          return result;
        },
        size: function () {
          return result.length;
        }
      };
      cb();
    })
  • iconfontFileDownloadEnd hook

    • hook类型: AsyncParallelHook

    • 描述:相关引用的字体文件下载完成结束后调用。hook注册时将接收以下参数:

      • arg1: fontFileList 准备输出字体文件资源数组列表
      • arg2: callback 回调函数,该函数可接受再次处理后的 fontFileList,便于您对 fontFileList 进行增删改等操作,当然您还可以不传入 fontFileList,这时插件将不会再把下载的引用的字体文件加入到输出资源列表中,该资源就成为您的盘中餐,可以为所欲为了。
    • 示例一:利用回调函数返回处理后的fontFileList,为其添加输出资源

    WebpackQcIconfontPlugin.getHooks.for('iconfontFileDownloadEnd').tapAsync(pluginName, (fontFileList, cb) => {
      const testFile = '测试使用的文件而已'
      fontFileList.push({
        filename: 'test.text',
        data: {
          source: function () {
            return testFile;
          },
          size: function () {
            return testFile.length;
          }
        }
      })
      cb(fontFileList)
    })
    • 示例二:用回调函数不返回值,自定义输出资源路径
    WebpackQcIconfontPlugin.getHooks.for('iconfontFileDownloadEnd').tapAsync(pluginName, (fontFileList, cb) => {
      fontFileList.forEach(file => {
        const name = file.filename.replace('./iconfont/iconfont','./css/iconfont/iconfont')
          compilation.assets[name] = file.data
      });
      cb()
    })
  • plugin.js

const WebpackQcIconfontPlugin = require('../src/index')
const pluginName = 'hook-test-plugin';

class HookTestPlugin {
  apply(compiler) {
    compiler.hooks.compilation.tap(pluginName, (compilation) => {
      // 测试 iconfontCssCreateEnd Hook
      WebpackQcIconfontPlugin.getHooks.for('iconfontCssCreateEnd').tapAsync(pluginName, (result, cb) => {
        result += '.test { width: 500px; }'
        cb(result)
      })

      // 测试 iconfontFileDownloadEnd Hook
      WebpackQcIconfontPlugin.getHooks.for('iconfontFileDownloadEnd').tapAsync(pluginName, (fontFileList, cb) => {
        const testFile = '测试使用的文件而已'
        fontFileList.push({
          filename: 'test.text',
          data: {
            source: function () {
              return testFile;
            },
            size: function () {
              return testFile.length;
            }
          }
        })
        cb(fontFileList)
      })
    })
  }
}
