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 🙏

一个简易版本的延迟加载图片,无任何依赖,支持ie9及以上版本浏览器。 暂时不支持divbackgroud的这种方式的延迟加载。

有以下特性:

  • 隔N秒后自动加载下屏图片
  • 加载图片后重新计算图片位置

接口说明

在使用延迟加载中,请先给予图片默认地址

<img src="/images/gray.png" data-origin="/images/1.png" alt="" />

当然你也可以用base64来作为占位符

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC"
  data-origin="/images/1.png"/>
Lazyload.init({
  el: '[data-origin]', //需要绑定延迟加载的元素
  attr: 'origin', //获取图片真实地址的data属性名
  autoLoad: true, //是否自动加载下屏图片
  delay: 2000, //自动加载下屏图片的间隔时间
  threshold: 0, //提前多少px预加载图片
  recalculate: false, //是否动态重新计算图片位置
});

//如果后期增加了DOM而需要重新刷新一下插件
Lazyload.refresh();
