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 Images Preload Plugin And Vite Images Preload Plugin

Images Preload Plugin 是一个用于在 Webpack 或者 Vite 构建过程中自动预加载或预获取图片资源的插件。通过配置不同的策略,可以在 HTML 文件中生成相应的 <link> 标签,以优化图片资源的加载性能。

安装

使用 npm 安装插件:

npm install images-preload-plugins --save-dev

使用方法

插件支持以下配置选项:

  • strategy:预加载策略,可以是 'preload' 或 'prefetch'。
  • assetDir:图片资源所在的目录路径。

插件导入

// webpack.config.js
import WebpackPreloadImagesPlugin from  'images-preload-plugins/webpack';

// vite.config.js
import VitePreloadImagesPlugin from 'images-preload-plugins/vite';

示例1

// webpack.config.js
module.exports = {
  // ...其他配置
  plugins: [
    new WebpackPreloadImagesPlugin([
      { strategy: 'preload', assetDir: 'src/assets/preload' },
      { strategy: 'prefetch', assetDir: 'src/assets/prefetch' },
    ]),
  ],
};

// vite.config.js
module.exports = defineConfig({
  // ...其他配置
  plugins: [
    VitePreloadImagesPlugin([
      { strategy: 'preload', assetDir: 'src/assets/preload' },
      { strategy: 'prefetch', assetDir: 'src/assets/prefetch' },
    ]),
  ],
});

示例2

// options {}
// webpack.config.js
module.exports = {
  //...其他配置
  plugins: [
    new WebpackPreloadImagesPlugin({
      strategy: 'preload',
      assetDir:'src/assets/preload'
    }),
  ],
};

// vite.config.js
module.exports = defineConfig({
  // ...其他配置
  plugins: [
    VitePreloadImagesPlugin({
      strategy: 'preload',
      assetDir:'src/assets/preload'
    }),
  ],
});

生成的 HTML 标签

  • 对于 preload 策略
<link rel="preload" as="image" href="path/to/image.jpg">
  • 对于 prefetch 策略
<link rel="prefetch" as="image" href="path/to/image.jpg">

注意事项

  • 确保 assetDir 路径正确,否则插件可能无法找到图片资源。
  • 如果使用的是私有 npm 仓库,确保你有正确的访问权限。
