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

webpack-sri-retry

基于webpack4的sri(subresource integrity)易用解决方案,参考整合webpack-subresource-integritywebpack-retry-load-plugin

  • 自动为静态资源js/css添加integrity标识
  • 绑定自动从你配置的其它域名 (retryPublicPath) 重新下载那些失败的资源
  • 插件必须配合 html-webpack-plugin
  • 可以配置监控,支持上报成功和失败的量

安装

npm install webpack-sri-retry -D

or

yarn add webpack-sri-retry -D

使用

combineConfig(config, options)

合并weback的config,不改变config。通常webapck配置文件中,使用该方法

const HtmlWebpackPlugin = require("html-webpack-plugin");
const { combineConfig } = require("webpack-sri-retry");

module.exports = combineConfig(
  {
    entry: {
      index: "./index.js",
    },
    output: {
      filename: "bundle.js",
      publicPath: "https://www.publicPath.com",
    },
    plugins: [
      new HtmlWebpackPlugin({
        template: "index.html",
      }),
    ],
  },
  {
    retryPublicPath: "https://www.retryPublicPath.com", // 重试cdn
  }
);

extend(config, options)

扩展weback的config,改变config。nuxtjs等框架中使用该方法

const { extendConfig } = require("webpack-sri-retry");

module.exports = {
  build: {
    extend(config, ctx) {
      if (ctx.isClient) {
        extendConfig(config, {
          retryPublicPath: "https://www.retryPublicPath.com", // 重试cdn
          ssr: true,
        });
      }
    },
    publicPath: "https://www.publicPath.com",
  }
};

Options

retryPublicPath

Type: string

Default: ''

自动从配置的retryPublicPath 重新下载失败的资源

如未配置,则资源加载失败后不会进行重试

hashFuncNames

Type: array

Default: ["sha256"]

如需特别配置参考:https://github.com/waysact/webpack-subresource-integrity/tree/1.x/#hashfuncnames

ssr

Type: boolean

Default: false

如需要在服务端渲染项目中使用:

  • 需配置ssr:true

  • 同时在服务端response页面时使用processedSSRTemplate方法对html模版页面进行处理(为动态注入的js、css添加integrity及失败重试处理等标识)

如在nuxt中,通过hooks对html进行处理:

'render:route'(url, result, context) {
    if (!context.spa) {
      result.html = processedSSRTemplate(result.html)
    }
  },

上报

入口模版中定义BJ_REPORT的report 或 reportFail、reportRetryFail

<script>
  var BJ_REPORT = {};
  BJ_REPORT.report = function (data) {
    // 可以上报所有成功失败的资源加载
  };

  BJ_REPORT.reportFail = function ({ src }) {
    // 便捷的首次加载失败上报
  };

  BJ_REPORT.reportRetryFail = function ({ newSrc }) {
    // 便捷的重试加载失败上报
  };
</script>
