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 🙏

特点

在 Ant Design Table 组件的基础,包装为一个高性能,易组合,超低开发成本的表格组件,让 CURD 操作变得简单

问题

在使用 Ant Design Table 组件的过程中,我发现以下问题:

  • 表格嵌套表格,行选择,自定义 render 组件,分页等操作缺少直观的代码。排错麻烦,容易产生 bug。
  • 难以支持复杂的表格编辑操作,表格添加行,上移,下移,删除等操作。要实现的代码很多,而且代码重复。
  • 性能不高,即使修改单行数据,也会触发整个表格的重新 render。

而且,Antd Design Table 缺少开箱即用的虚拟滚动实现,并且限制还有:

  • 不支持 column 的 render,fixed,仅支持 column 的 width
  • 不支持 rowSelection
  • 不支持 edit
  • 不支持 tree 数据
  • 不透明开关,打开虚拟列表和,不打开虚拟列表,代码差异很大,会波及其他代码都要改

解决

antd-formily-boost 从Formily的先进的 Reactive 与 Schema 设计出发,大幅简化对 Table 组件的实现。它的特点是:

  • Schema 与 Data 分离,我们能看到代码中仅仅在 Form 的顶头处传送了一次 data 以外,其他地方就没有写过关于 data 的代码。Formily 会通过 Schema 结构自动抽取正确的 Data 位置,并对这些位置的数据进行读写操作。
  • 可读性好,以上的代码同时实现了行选择,与分页功能。开发者需要的心智更少,只需要关注 Schema 的结构是如何在 XML 中表达就可以了,
  • 性能更好,Formily 机制尽可能少地触发整个 Table 的 render 操作
  • 动态性更好,基于 Formily 的实现,我们可以轻松实现任意列的动态控制显示与隐藏,同一行中不同列数据的联动,甚至直接从后端或者可视化编辑器中生成以上代码都可以。

最后 antd-formily-boost 的目前版本中,有开箱即用的虚拟滚动实现,像上面这种代码,只需加入 virtualScroll 属性就能打开虚拟滚动,让开发者无痛一键使用表格虚拟滚动的功能,虚拟滚动支持的场景包括有:

  • 支持 column 的 width,fixed,以及自定义嵌套组件
  • 支持 rowSelection,checkbox 在树形数据下依然有点问题,在其他情况下运行正常
  • 支持 edit
  • 支持 RecursiveRow 或 ChildrenRow 这种树形数据,但依然不支持 ExpandableRow 的任意 expand 的树形数据
  • 透明开关,打开虚拟列表和,不打开虚拟列表,仅仅是一个属性设置而已,其他代码不用改
