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

html2canvas-paging

当使用html2canvas进行截图时,当被截图的内容长度超过浏览器canvas长度的限制,超出的部分会被忽略,为了突破浏览器canvas最大高度的限制,你可以使用 html2canvas-paging 将截图内容进行分页,返回多个被截取内容。

使用

html2canvas-paging的用法与html2canvas完全相同,当你不需要分页截取的时候,你可以把它当做一个html2canvas的包裹器。具体的参数可以参照html2canvas使用文档

需要注意的是, html2canvas-paging 返回的promise对象, 将返回一个canvas数组,而不是一个canvas对象

import html2canvas from 'html2canvas-paging'

html2canvas(document.body).then(function(canvases) {
    canvases.forEach(canvas => {
      document.body.appendChild(canvas);
    })
});

当你需要分页截图的时候, html2canvas-paging 在 html2canvas 支持的可选参数之上, 新增了paging参数, 你可以设置分页截取图片的 widthheight

import html2canvas from 'html2canvas-paging'

html2canvas(document.body, {
  paging: {
    width: 1000,
    height: 10000
  }
}).then(function(canvases) {
    canvases.forEach(canvas => {
      document.body.appendChild(canvas);
    })
});
