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 🙏

#vuefinger 一款基于vue1.0的手势库

#demo ![太阳系][1] [1]: https://raw.githubusercontent.com/Samlin901211/img/master/vuefinger/vue1.0_demo.png

#使用说明

  • 安装 npm install vuefinger --save
  • 引入
  import Vue from 'vue'
  import Vuefinger from 'vuefinger'
  Vue.use(Vuefinger)
  • 在需要绑定手势事件的元素上绑定v-finger:options,需要绑定的回调写在options中

例如:

 <template>
   <div class="demo" v-finger:options="options">
      <img class="demo_img" src="./demo.jpg">
   </div>
</template>
<script>
  import Vue from 'vue'
  import VueFinger from 'vuefinger'
  Vue.use(VueFinger)
 
  export default {
     data () {
        return {
           options: {
              tap:function() {
                   alert("tap")
              }
            }
         }
      }
  }

#事件支持

  • 回调函数this指向绑定手势的元素
  • 点击 tap 回调值:无
  • 长按 longpress 回调值:无
  • 双击 doubletap 回调值:无
  • 缩放 pinch 回调值:{scale:"“}
  • 旋转 rotate 回调值:{rotate:”“}
  • 滑动 swipe 回调值:{direction:”“} //up、down、left、right
  • 按住拖动 pressmove 回调值:{disX:”",disY}
  • 单指开始回调 singlestartcallback 回调值:无
  • 单指结束回调 singleendcallback 回调值:无
  • 多指开始回调 multistartcallback 回调值:无
  • 多指结束回调 multiendcallback 回调值:无

#其他说明

  • 目前暂时不支持vue2.0,因为指令传参发现无法传递函数,故后续会采用新的方案,尽情期待哈
  • 使用了transform.js,增强了元素的功能,自动监控元素的transform3D相关属性 rotateX,rotateY,rotateZ scaleX,scaleY,scaleZ translateX,translateY,translateZ 例如:
<template>
   <div class="demo" v-finger:options="options">
      <img class="demo_img" src="./demo.jpg">
   </div>
</template>
<script>
  import Vue from 'vue'
  import VueFinger from 'vuefinger'
  Vue.use(VueFinger)
 
  export default {
     data () {
        return {
           options: {
               pinch:function(evt) {
                    var scale = evt.scale;
                    this.scaleX = this.scaleY = this.prescaleX * scale;           
                },
               multistartcallback: function() {
                    this.prescaleX = this.scaleX;
                    this.prerotateZ = this.rotateZ;
                },
                rotate:function(evt) {
                    this.rotateZ = this.prerotateZ + evt.rotate;
                }
            }
         }
      }
  }
