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 🙏

page-skeleton-core

基于url生成骨架屏结构核心代码

核心源码来自elemeFE开源的一款webpack骨架屏插件page-skeleton-webpack-plugin

在插件代码中提取出生成骨架结构的核心逻辑,适用于对骨架屏有定制化需求的场景。

Installation

npm install page-skeleton-core

Basic Use

const {SkeletonBuilder} = require('page-skeleton-core');

let skeletonBuilder = new SkeletonBuilder({
    preview: true, // 预览骨架屏模式
    defer: 5000
}, console.log);

(async () => {
    const result = await skeletonBuilder.build('https://m.baidu.com/');
    console.log(result);
})();

示例

construct options

参考page-skeleton-webpack-plugin的options说明,https://github.com/ElemeFE/page-skeleton-webpack-plugin

下面仅对新增字段进行说明。

| Option | Type | Required | Default | Description | | --------------- | ------- | -------- | ------- | ------------------------------------------------------------ | | preview | Boolean | No | false | 预览模式,将不会返回骨架结构结果,仅在浏览器预览效果 | | waitForSelector | String | No | none | 参考puppeteer waitForSelector参数。等待某个选择器的元素加载之后,适用于等待某个异步的结果后执行。相比defer参数更加精准一些。 |

methods

SkeletonBuilder.build(url)

  • url 要生成骨架屏的页面url地址
  • returns Promise对象,包含生成的骨架结构代码

预览模式下返回true

// 预览模式
if (preview) return Promise.resolve(true);

非preview模式下返回Object,Object包含三个参数:

html完整的骨架屏html结构代码字符串。

styles 骨架结构相关样式。

cleanedHtml 骨架DOM结构。

let shellHtml = `<!DOCTYPE html>
    <html lang="en">
    <head>
    <meta charset="UTF-8">
    <title>Page Skeleton</title>
    <style>
    $$css$$
    </style>
    </head>
    <body>
    $$html$$
    </body>
    </html>`;
shellHtml = shellHtml
    .replace('$$css$$', finalCss)
    .replace('$$html$$', cleanedHtml);
const result = {
    html: htmlMinify(shellHtml, false),
    styles: finalCss,
    cleanedHtml: cleanedHtml
};
