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 🙏

  created: function () {
    this.folderData = TEST_DATA
    
    // 如果需要使用 getPath 方法则需要等待 folder-tree 组件渲染后再赋值 value
    // 否则会报错
    this.$nextTick(function () {
      this.selectedFolderId = this.folderData[ 0 ].id
    })
  },

      pathData.forEach(function (item, i) {
        result += item.name
        if (i !== pathData.length - 1) {
          result += ' > '
        }
      })
      
      return result
    }
  }
}).$mount('.root')

prop

  • value,可以用 v-model 双向绑定,会高亮选中的目录。
  • data,目录数据,建议用 .sync 双向绑定,仅会改变数据中的 expand 字段(是否展开)

event

  • input,v-model
  • update:data,data.sync
  • on-click,点击目录后会通知该事件,参数为点击条目的数据

prop data 解释

/**
 *  文件夹目录数据,用 .sync 语法糖双向绑定,内部会改变 expand 状态
 *  实现功能只需要 id、parentId、name、children
 *  parentId 为上一级的 ID,getPath 方法使用
 *  expand 是否展开子目录
 *  other 为其他数据,事件中会一并向上传递
 *  {
 *    id: Any,
 *    name: String,
 *    expand: Boolean
 *    other: Any,
 *    children: [
 *      {
 *        id: Any,
 *        name: String,
 *        parentId: String
 *        expand: Boolean
 *        other: Any
 *        children: [],
 *      }
 *    ],
 *  }
