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

html-webp-plugin

在构建阶段自动将 HTML 中的 <img> 标签转换为 <picture>,为支持 WebP 的浏览器提供更优的图片格式,同时保留原始格式作为降级方案。

安装

npm install html-webp-plugin --save-dev
# or
yarn add -D html-webp-plugin

使用

const HtmlWebpackPlugin = require('html-webpack-plugin');
const HtmlWebpPlugin = require('html-webp-plugin');

module.exports = {
  plugins: [
    new HtmlWebpackPlugin({ /* ... */ }),
    new HtmlWebpPlugin({
      include: /\/img\//,
      exclude: null
    })
  ]
};

⚠️ 请确保在 HtmlWebpackPlugin 之后实例化本插件。

配置项

| 选项 | 说明 | 默认值 | | --- | --- | --- | | include | 需要转换的图片路径正则 | /\/img\// | | exclude | 需排除的图片路径正则 | null | | preserveAttributes | 是否保留原 <img> 的所有属性 | true |

处理流程

  1. HtmlWebpackPlugin 输出 HTML 前,将符合条件的 <img> 转换为 <picture>
  2. 在构建完成后校验 WebP 文件是否存在,缺失则自动回退为原 <img>
  3. 自动移除懒加载类名、data-src 等占位属性。
