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 🙏

使用 CanvasRenderingContext2D 绘制各类图形。

包含了两个插件:

  1. CanvasRendererPlugin 实现了以下 hook:

    1. beginFrame 保存上下文,如果开启了脏矩形渲染,创建脏矩形对应的 clip rect 并擦除
    2. renderFrame 绘制各个图形,如果开启了脏矩形渲染,仅在该区域内重绘
    3. endFrame 恢复上下文
  2. LoadImagePlugin 负责加载图片,实现了以下 hook:

    1. mounted Image 图形首次进入画布,异步加载包含的图片
    2. attributeChanged 如果 Image 图形的图片地址发生改变,重新加载图片
