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 🙏

ae86-app-base-webpack-config

基于 webpack-chain 封装的基础通用的 webpack 配置

介绍

ae86-app-base-webpack-config 是用于构建 Ae86 App 的基础 webpack 配置,其内部使用 webpack-chain 实现。

除此之外,ae86-app-base-webpack-config 还提供了 react 编译所需的 babel 配置。

API

ae86-app-base-webpack-config 对外提供如下 API,使用该 API 就可以得到对应的基础配置:

  1. getBabelConfig 得到 react 相关的 babel 配置
  2. getWebpackConfig 得到基础的 webpack 配置

getBabelConfig

getBabelConfig 的实现如下,可以看到具体的 babel 配置:

export = (isEnvDevelopment = false) => {
  return {
    presets: [
      [require.resolve('@babel/preset-env'), {}],
      [require.resolve('@babel/preset-react'), { runtime: 'automatic' }],
      require.resolve('@babel/preset-typescript'),
    ],
    plugins: [
      true
      && isEnvDevelopment
      && require.resolve('react-refresh/babel'),
    ].filter(Boolean),
    babelrc: false,
    configFile: false,
    cacheDirectory: true
  };
};

getWebpackConfig

getWebpackConfig 的实现如下:

import getBaseConfig = require("./webpack.base");
import getBuildConfig = require("./webpack.build");
import getDevConfig = require("./webpack.dev");
import chain = require("webpack-chain");

export = (
  mode: Mode = "development",
  config: chain,
  options?: ConfigOptions
) => {
  options = options || {};
  getBaseConfig(mode, config, options);
  if (mode === "development") {
    getDevConfig(config);
  } else {
    getBuildConfig(config);
  }
  return config;
};

根据 mode 的值可以获取开发、生产环境下的配置。

样式配置

ae86-app-base-webpack-config 内置对 css、less、sass、scss 的处理,其内部使用的 loader 和默认配置如下: | loader | 默认配置 | 说明 | | :---- | :---- | :---- | | miniCssExtractPlugin.loader | {esModule: false} | cssInline 为 false 的时候启用 | |style-loader | | | | css-loader | {  importLoaders:1,  sourceMap:true,  modules:  {    localIdentName:"[folder]-[local]-[contenthash:8]"  }  } | sourceMap 配置只针对生产环境,开发环境恒为 true。其中 modules 配置仅在开启 css modules 功能后才生效,例如使用 index.module.css,就会触发该配置 | | less-loader | {   lessOptions: { javascriptEnabled: true   }} | | | sass-loader | | | | postcss-loader | {sourceMap:true} | sourceMap 配置只针对生产环境,开发环境恒为 true |

样式的自定义配置

有时候,开发者希望对 loader 的配置进行修改。当然,我们提供了这个能力。使用 ae86-app-base-webpack-config 的时候,可以传入如下选项进行样式相关的自定义配置:

getBaseConfig(mode, config, {
  // 其他配置
  cssInline: false, // 默认false,该值决定使用miniCssExtractPlugin.Loader还是css-laoder
  sourceMap: true, // 该配置只针对生产环境,开发环境恒为true
  cssOptions:{
     miniCssExtractPluginLoaderOptions: {
      // miniCssExtractPluginLoader相关的配置
     };
    styleLoaderOptions: {
      // style-loader相关的配置
    };
    cssLoaderOptions: {
      // css-loader相关的配置
    };
    lessLoaderOptions: {
      // less-loader相关的配置
    };
    sassLoaderOptions: {
    // sass-loader相关的配置
    };
    postcssLoaderOptions: {
      // postcss-loader相关的配置
    };
  }
});

通过 cssOptions 配置可以增加额外的 loader 配置,如果属性名称和内置的属性相同,则会覆盖掉默认配置

字体资源配置

配置中使用了 url-loader 相关的字体资源做进行处理,具体配置如下: | 字体 | 默认配置 | 说明 | | :---- | :---- | ----- | | woff2 | { mimetype: "application/font-woff", name:'font/[name][ext]',limit: URL_LOADER_LIMIT, } | 其中 URL_LOADER_LIMIT 为 8192 | | ttf | { mimetype: "application/octet-stream", name:'font/[name][ext]',limit: URL_LOADER_LIMIT, } | 其中 URL_LOADER_LIMIT 为 8192 | | eot | { mimetype: "application/vnd.ms-fontobject", name:'font/[name][ext]',limit: URL_LOADER_LIMIT, } | 其中 URL_LOADER_LIMIT 为 8192 | | svg | { mimetype: "image/svg+xml", name:'font/[name][ext]',limit: URL_LOADER_LIMIT, } | 其中 URL_LOADER_LIMIT 为 8192 |

图片资源配置

对图片资源的处理使用了 webpack5 中的 asset/resource 模块,具体配置代码如下:

config.module
  .rule("images")
  .test(/\.(png|jpg|webp|jpeg|gif)$/i)
  // @ts-ignore
  .type("asset/resource")
  .set("generator", {
    filename: "images/[name][ext]",
  })
  .parser({
    dataUrlCondition: {
      maxSize: URL_LOADER_LIMIT,
    },
  });
// 对应的webpack配置为
{
    test: /\.(png|jpg|webp|jpeg|gif)$/i,
    type: 'asset/resource',
    generator: {
      filename:  "images/[name][ext]"
    },
    parser: {
      dataUrlCondition: {
        maxSize: URL_LOADER_LIMIT,
      },
    }
},

其中 URL_LOADER_LIMIT 为 8192

babel 配置

我们内置了相关的 babel 配置,用于来处理 react,其配置如下:

{
  presets: [
    [require.resolve('@babel/preset-env'), {}],
    [require.resolve('@babel/preset-react'), { runtime: 'automatic' }],
    require.resolve('@babel/preset-typescript'),
  ],
  plugins: [
    isEnvDevelopment
    && require.resolve('react-refresh/babel'),
  ].filter(Boolean),
  babelrc: false,
  configFile: false,
  cacheDirectory: true
}

其中 react-refresh/babel 在开发环境才会生效

其他配置

  1. resolve 中 extensions 的配置:['.js', '.json', '.jsx', '.ts', '.tsx']

以上都是开发环境和生产环境一些通用的配置,在不同环境中配置也有不同。

开发环境额外配置

开发环境在基础配置上增加如下配置:

  1. soure map: cheap-module-source-map
  2. react 热更新支持(基于@pmmmwh/react-refresh-webpack-plugin)

生产环境额外配置

生产环境在基础配置上增加如下配置:

  1. optimization 配置,使用了 terser-webpack-plugin 和 css-minimizer-webpack-plugin 对 js 和 css 进行优化

更多配置,请阅读ae86-app-base-webpack-config

深度的自定义配置

你可以使用 webpack-chain 对的到的配置进行深度的修改,包括新增、修改、删除等。在此之前你需要去看看 ae86-app-base-webpack-config 的源码实现,它并不难
