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 🙏

💡 与Element cascader的区别项

  1. el-cascader当option重复时,会出一个空白节点

    解决逻辑:重复时保留老节点,舍去新节点

  2. el-cascader多选状态下,第一个搜索词选中内容后,搜索词被清空

    解决逻辑:保留第一个搜索词

  3. props中新增属性

| 参数 | 说明 | 类型 | 可选值 | 默认值 | | --- | --- | --- | --- | --- | | selectWithExpand | 单选且checkStrictly为true时是否展开下一级 | boolean | - | false | | lazyMultiCheck | 多选且懒加载时取值 | boolean | - | false | | panelLabels | 面板标题 | Array | - | [] | | checkAll | 多选且checkStrictly为true时全选 | boolean | - | false | | panelSearch | 面板搜索 | boolean | - | false | | panelLabels | 面板搜索标题 | Array | - | [] | | panelPlaceholder | 面板搜索placeholder | Array | - | [] | | expandPanels | 默认展开面板数 | number | - | 0 | | emptyText | 无匹配数据时展示文案 | string | - | '暂无数据' |

  1. Cascader、CascaderPanel 新增事件

| 参数 | 说明 | 回调参数 | --- | --- | --- | | lazy-loaded | 惰性加载完毕后触发 | 选中节点的值 |
