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 🙏

简介

resource-hint-webpack-plugin 集成了 Resource Hints 的能力,能够在打包时自动添加 link 标签到 html 中。

基于 @vuejs/preload-webpack-plugin,强化了配置功能 options,并且新增支持 dns-prefetch / prerender / preconnect 的能力。

<link href="src_async_js.f23b5bce.js" rel="preload" as="script">
<link href="https://example.com/fonts/font.woff" rel="preload" as="font" crossorigin>
<link href="src_async_js.f23b5bce.js" rel="prefetch">
<link href="//fonts.googleapis.com" rel="dns-prefetch">
<link href="https://www.keycdn.com" rel="prerender" >
<link href="https://cdn.domain.com" rel="preconnect" crossorigin>

内容列表

预检查

确保 webpack 的版本在 5 以上,并且正在使用 html-webpack-plugin

const HtmlWebpackPlugin = require('html-webpack-plugin');
const { ResourceHintWebpackPlugin } = require('resource-hint-webpack-plugin');

module.exports = {
  /* ... */
  plugins: [
    new HtmlWebpackPlugin({
      template: './public/index.html',
      filename: 'index.html',
      chunks: ['index'],
      inject: 'body'
    }),
    new ResourceHintWebpackPlugin([{
      rel: 'preload',
      include: {
        type: 'asyncChunks',
      }
    }])
  ]
  /* ... */
}

安装

通过 npm 安装,并将其添加到开发时依赖中 devDependencies:

npm install resource-hint-webpack-plugin --save-dev

或者

通过 yarn 安装:

yarn add resource-hint-webpack-plugin --dev

配置项

配置项改造成了一个数组,支持传入多个 options,下面是单个的配置项:

|字段名|类型|默认值|描述| |:---:|:-:|:---:|:--| |rel|{String}|-|脚本的预加载模式| |include|{{IncludeOption}}|-|指定需要预加载的脚本|

Hints

preload

preload 允许预加载在 CSS 和 JavaScript 中定义的资源,并允许决定何时应用每个资源,需要配合 webpack 懒加载

new ResourceHintWebpackPlugin([{
  rel: 'preload',
  include: {
    type: 'asyncChunks',
  }
}])

prefetch

prefetch 是一个低优先级的资源提示,允许浏览器在后台(空闲时)获取将来可能用得到的资源,并且将他们存储在浏览器的缓存中。

new ResourceHintWebpackPlugin([{
  rel: 'prefetch',
  include: {
    type: 'asyncChunks'
  }
}])

dns-prefetch

dns-prefetch 允许浏览器在用户浏览页面时在后台运行 DNS 的解析。

new ResourceHintWebpackPlugin([{
  rel: 'dns-prefetch',
  include: {
    hosts: ['//fonts.googleapis.com']
  }
}])

prerender

prerender 优化了可能导航到的下一页上的资源的加载,在后台渲染了整个页面和整个页面所有的资源。

要小心的使用 prerender,因为它将会加载很多资源并且可能造成带宽的浪费,尤其是在移动设备上,并且可能会造成一些副作用

new ResourceHintWebpackPlugin([{
  rel: 'prerender',
  include: {
    hosts: ['https://www.keycdn.com']
  }
}])

preconnect

preconnect 允许浏览器在一个 HTTP 请求正式发给服务器前预先执行一些操作,这包括 DNS 解析,TLS 协商,TCP 握手,这消除了往返延迟并为用户节省了时间。

new ResourceHintWebpackPlugin([{
  rel: 'preconnect',
  include: {
    hosts: ['https://cdn.domain.com']
  }
}])

进阶用法

指定 chunk 和 entry

在使用 prefetchpreload 时,可以指定 chunks 或者 entries 的值来确定需要生成 link 的页面。

module.exports = {
  output: {
    filename: '[name].[contenthash:8].js',
    path: path.resolve(__dirname, 'dist')
  }
  plugins: [
    //...
    new ResourceHintWebpackPlugin([{
      rel: 'preload', // 或者 prefetch
      include: {
        chunks: ['index']
      }
    }])
  ]
}
module.exports = {
  entry: {
    index: './src/index.js',
    index2: './src/index2.js'
  },
  plugins: [
    //...
    new ResourceHintWebpackPlugin([{
      rel: 'preload', // 或者 prefetch
      include: {
        entries: ['index2']
      }
    }])
  ]
}

指定 htmls

所有的 hints 支持指定 htmls

new ResourceHintWebpackPlugin([{
  rel: 'dns-prefetch', // prerender, preconnect, preload, prefetch
  include: {
    htmls: ['index.html']
  }
}])

批量添加

本插件增强了 options 的能力,能够同时插入不同的 hints

new ResourceHintWebpackPlugin(
  [
    {
      rel: 'preload',
      include: {
        type: 'asyncChunks'
      }
    },
    {
      rel: 'dns-prefetch',
      include: {
        hosts: ['//fonts.googleapis.com']
      }
    },
    {
      rel: 'prerender',
      include: {
        hosts: ['https://www.keycdn.com']
      }
    },
    {
      rel: 'preconnect',
      include: {
        hosts: ['https://cdn.domain.com']
      }
    }
  ]
)
