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 🙏

开发备忘

数据管理路径 目前数据管理路径链条较长，将关键逻辑记录于此，便于后续维护和扩展

1.用户在option配置中传入data 2./core/optionParser parseDataset()
将各种data格式统一为DataItem[][]格式，并挂在chart对象上 （chart.series为用户配置项的series子项，内部data字段同chart.dataset） 3./components/axis/index dataAdaptor()
将chart.dataset作为数据输入，并根据配置处理数据，输出格式为DataItem[][]，传入/组件中 4./components/axis/axis

  • 根据坐标轴类型base/value，解析对应的baseAxisData/valueAxisData,并进行后续绘制逻辑
  • 当坐标轴类型为value时，preProcessData()解析valueAxisData，并processGlobalData()中解析max/min，并挂载在globalData上。 5./graphs/line /graphs/bar chart.getGlobalData()获取valueAxis的max/min信息，并根据比例进行图表绘制
