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 🙏

mytouch 自定义指令

基于Vue2touch操作, 需要掌握Vue的指令操作, 暂未测试 PC 端效果. 依赖Babel(因为 ES6...), Vue( (:з」∠) ) Sorry for my poor English, English document will be displayed after a time.

引入操作

  • 安装cyj-vue-touch
# install mytouch
npm install cyj-vue-touch
  • 调用
import 'cyj-vue-touch'

指令操作书写

// 在标签中书写
v-mytouch:Action.modifiers="fun"
// 默认调用函数时传入event参数,
// 其中event参数增加键值对 catagory: Action
v-mytouch:Args="argument"
  • Action不区分大小写

常用指令

| Action | 说明 | 函数参数 | | ------------- | :----------: | :-------------------: | | tap | 轻触事件 | event | | doubleclick | 双击事件事件 | event | | press | 长按事件 | event | | swipe | 滑动事件 | event, 滑动角度 | | swipeLeft | 左滑事件事件 | event, 滑动角度 | | zoomIn | 放大事件 | event, 双指形成角度 |

点击事件指令

| Action | 说明 | catagory 值 | 函数参数 | | ------------- | :--------------------------------: | :-------------: | :------: | | tap | 轻触事件, 是click0的语法糖 | 'tap' | event | | doubleclick | 双击事件, 是click1的语法糖 | 'doubleclick' | event | | click0 | 在连按 0 下后单击, 即轻触事件 | 'tap' | event | | click1 | 在连按 1 下后单击, 即双击事件 | 'doubleclick' | event | | click n | (n>1)在连按 n 下后单击, 即多击事件 | 'click' + n | event | | n | 即click n | 即click n | event |

长按事件指令

| Action | 说明 | catagory 值 | 函数参数 | | --------- | :---------------------------: | :-----------: | :------: | | press | 长按事件, 是press0的语法糖 | 'press' | event | | press0 | 在连按 0 下后长按, 即长按事件 | 'press' | event | | press n | (n>0)在连按 n 下后长按 | 'press' + n | event |

移动事件指令

| Action | 说明 | catagory 值 | 函数参数 | | ------- | :--------------------------------------------------: | :----------: | :---------------------------------------------: | | move | 本质即touchmove事件, 会持续触发, 是move0的语法糖 | 'move' | event, x偏移量, y偏移量, x初始位置, y初始位置 | | moven | (n>0)在连按 n 下后, 移动会持续触发 | 'move' + n | event, x偏移量, y偏移量, x初始位置, y初始位置 |

滑动事件指令

| Action | 说明 | catagory 值 | 函数参数 | | ---------------- | :-------------------------------: | :-------------------------: | :----------------: | | swipe | 滑动事件 | 'swipe' | event 滑动角度 | | swipedegn | 向 n° 方向滑动事件 | 'swipedeg' + n | event 滑动角度 | | swipen | 连续点击 n 次后的滑动事件 | 'swipe' + n | event 滑动角度 | | swipen1degn2 | 连续点击 n1 次后的向 n2° 滑动事件 | 'swipe' + n1 + 'deg' + n2 | event 滑动角度 | | swipen1Left | swipen1deg180的语法糖 | 'swipe' + n1 + 'deg180' | event 滑动角度 | | swipen1Up | swipen1deg270的语法糖 | 'swipe' + n1 + 'deg270' | event 滑动角度 | | swipen1Right | swipen1deg0的语法糖 | 'swipe' + n1 + 'deg0' | event 滑动角度 | | swipen1Down | swipen1deg90的语法糖 | 'swipe' + n1 + 'deg90' | event 滑动角度 |

  • 滑动角度: 以横向向右(x 轴)为初始边, 纵向下(负 y 轴)为 90° 边(即屏幕坐标系), swipe 中的取值为[0,360)
  • swipe后紧跟两个参数, 因此用deg作为区分, 例如 swipe4deg90 表示在连续点击 4 次后触发向上滑动时触发的事件

放缩事件指令

| Action | 说明 | catagory 值 | 函数参数 | | ---------- | :----------------------: | :----------: | :----------------------------------------------------------------: | | zoomIn | 双指远离事件, 即放大事件 | 'zoomin' | event 双指形成角度 | | zoomOut | 双指接近事件, 即缩小事件 | 'zoomout' | event 双指形成角度 | | zoomMove | 双指放缩事件, 会持续触发 | 'zoomMove' | event 双指所形成角度 双指之间的距离 双指之间的距离的初始值 |

  • 滑动角度: 以横向向右(x 轴)为初始边, 纵向下(负 y 轴)为 90° 边(即屏幕坐标系), zoom 中的取值为[-90,90)

| modifiers | 说明 | | --------- | :-------------------------------------------------: | | prevent | 阻止浏览器默认行为, 一般需要设置用来阻止click事件 |

  • 暂未添加更多, 如有需要可以增加......

指令参数列表

| Args | 说明 | 数据类型 | 默认值 | 单位 | 取值 | | ------------------ | :-------------------------------------------------: | :------: | :----: | :------: | :--: | | delay | 区分轻触长按的时间间隔 | Number | 400 | ms | / | | maxDistance | 区分是否属于同一位置的最大偏移量 | Number | 10 | px | / | | minSwipeDistance | Swipe!区分是否触发滑动的最小距离 | Number | 50 | px | / | | minSwipeSpeed | Swipe!区分是否触发滑动的最小平均速度 | Number | 0 | px/100ms | / | | maxSwipeDeg | Swipe!区分是否触发具体角度的swipe事件的容差角度 | Number | 20 | deg | / | | minZoomDistance | Zoom!区分是否触发的zoom事件的最小变化距离 | Number | 60 | px | / | | manZoomDeg | Zoom!区分是否触发的zoom事件的最大角度容差 | Number | 20 | deg | / |

  • Args不区分大小写
  • maxswipedeg是指上或下浮动的范围, 例如swipe90deg在默认的取值范围是70-110

Demo1

<!-- html/template 绑定轻触事件 -->
<div v-mytouch:tap.prevent="handleTap" />
<!-- 以下是语法糖 -->
<div v-mytouch:click0.prevent="handleTap" />
<div v-mytouch:0.prevent="handleTap" />
// 引入
import 'cyj-vue-touch'
// VueScript
export default {
  // ...
  methods: {
    handleTap(e) {
      console.log(e.catagory) // 应该输出 'tap'
    }
  }
}

Demo2

  • 实现图片的展示功能
<!-- CSS已省略 -->
    <div id="app">
        <!-- 允许轻触或放大操作进行展示, 图片较小, 因此就减小zoom触发距离 -->
        <img src="./assets/logo.png" v-mytouch:tap="showImg" v-mytouch:zoomIn="showImg" v-mytouch:minZoomDistance="20">
        <!-- 允许轻触隐藏, 长按保存图片, 双击放大缩小 -->
        <div id="imgBox" v-show="show" v-mytouch:tap="hideImg" v-mytouch:press="saveImg" v-mytouch:1="changeScale" v-mytouch:zoomMove="moves" v-mytouch:minZoomDistance="0">
            <img src="./assets/logo.png" :style="imgStyle">
        </div>
    </div>
// 引入
import 'cyj-vue-touch'
// VueScript
export default {
  // ...
  methods: {
    showImg() {
      this.show = true
    },
    hideImg() {
      this.show = false
      this.scale = 1
    },
    saveImg() {
      confirm('是否保存图片')
    },
    changeScale() {
      if (this.scale != 1) this.scale = 1
      else this.scale = 2
    },
    moves(e, angel, dis, dispre) {
      let b = dis / dispre
      b = Math.max(Math.min(b, 2.5), 0.5)
      this.scale = b
    }
  },
  data() {
    return {
      show: false,
      scale: 1
    }
  },
  computed: {
    imgStyle() {
      return { transform: 'translate(-50%,-50%) scale(' + this.scale + ')' }
    }
  }
}
