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 🙏

wx-wow

该项目为提供微信小程序一套便捷好用动画执行方案, 通过添加简单的动画类名和一些简单的参数,即可实现想要的动画效果。灵感来源 WOW.js

wx-wow 需要 调试小程序基础库 >2.5

仓库地址: @Five-great/wx-wow

下载

直接通过 git 下载 wx-wow 源代码,并将 src 目录拷贝到自己的项目中

git clone https://github.com/Five-great/wx-wow.git

通过 npmcnpm 下载

 npm install --save wx-wow

下载后目录结构为


+-- src
|   |-- wxWOW.js
|   |-- wxWOW.wxs
|   |-- wxWOW.wxss
|   |-- wxWOW.min.js
|   |-- wxWOW.min.wxs
|   |-- wxWOW.min.wxss
|-- package-lock.json
|-- package.json
+-- README.md

使用

src 目录中所有文件复制到微信小程序目录utils中(wxWOW.jswxWOW.wxsswxWOW.wxss

1. 在 app.js 中引入 wxWOW.js

  Page = require('./utils/wxWOW')
  App({
     ...
  })

2. 在 app.wxss 引入wxWOW.wxss ( 动效样式来源自 animate.css(点击查看动效名与效果) )

 /**app.wxss**/
 @import "./utils/wxWOW.wxss";

3. 在需要的页面引入 wxWOW.wxs 并导出模块 命名为 "wx" 同时监听绑定 {{ wxwow }} 改变时触发 WOWChange 函数 执行动画渲染。


  <wxs src="../../utils/wxWOW.wxs" module="wx" />
  <view change:prop="{{wx.WOWChange}}" prop="{{wxwow}}" >
       ...
 </view>

4. 在需要加入动效的地方的 class 加入 " {{wx.WOW()}} <动效名称>", 例如 " {{wx.WOW()}} bounceInUp ", 同时需要给该动效分配一个 id 具体通过 {{wx.WOWId()}} 去自动分配到 data-wx-wow-id 上 ,并且确保添加动画的display 属性为 块状 或行块状,不能为行类样式 如下面的例子1。

 //例子1:
 <view class=" {{wx.WOW()}} bounceInUp"  data-wx-wow-id="{{wx.WOWId()}}" > ... </view>

额外参数

此外还可以控制动效的一些过程例如:

动效名称: data-wx-wow-name (bounceInUp , fadeInLeft,...)

动效延时: data-wx-wow-delay ( 300ms , 0.3s, 4s ...)

动效持续时间:data-wx-wow-duration ( 300ms , 0.3s, 4s ...)

距离可视区域多少开始执行动效: data-wx-wow-offset (整数) ( 0 , 100, 50 ...)

动效执行次数: data-wx-wow-iteration ( 1, 5, infinite, ...)

 <view class="{{wx.WOW()}} bounceInUp"  data-wx-wow-id="{{wx.WOWId()}}"  data-wx-wow-delay="0.8s" data-wx-wow-offset="500" > ... </view>
 
 <image src="xxxx.png" class="{{wx.WOW()}} swing"  data-wx-wow-id="{{wx.WOWId()}}"  data-wx-wow-delay="0.8s" data-wx-wow-offset="500" data-wx-wow-iteration="5" />

<view class="{{wx.WOW()}} fadeOut"  data-wx-wow-id="{{wx.WOWId()}}"  data-wx-wow-delay="0.8s"  data-wx-wow-duration="3s" > ... </view>

升阶配置

若需升阶配置 则需改变设置方式,在 class 加入 " {{wx.WOW()}}" ,同时加入 data-wx-wow-name="<动效名>" 同时需要给该动效分配一个 id 具体通过 {{wx.WOWId()}} 去自动分配到 data-wx-wow-id 上 ,并且确保添加动画的display 属性为 块状 或行块状,不能为行类样式 如下面的例子2

//例2:
 <view class=" {{wx.WOW()}} " data-wx-wow-name="bounceInUp" data-wx-wow-id="{{wx.WOWId()}}" > ... </view>

触发实现离场动效

通过触发 wx.WOWOut() 函数,来触发离场动效,需保证 data-wx-wow-name有值,默认为 data-wx-wow-name中相反的动效名(例如 bounceInUp 相反动效为 bounceOutUp)。触发回调对应逻辑层 wxWOWTap(可以执行跳转页面或其他处理)
 <view class=" {{wx.WOW()}} " data-wx-wow-name="bounceInUp" data-wx-wow-id="{{wx.WOWId()}}"  catchtap="{{wx.WOWOut}}" > ... </view>
Page({
  ...
  wxWOWTap: function(event){
      console.log(event)
     setTimeout(()=>{
      event.target.dataset.idx?wx.navigateTo({url: '/pages/xxx/xxx?idx='+event.target.dataset.idx}):''
     },600)
  }
  ...
})
可选配置

此外还可以控制动效的一些过程例如:

动效名称: data-wx-wow-outName [默认data-wx-wow-name取相反动效 ] (bounceOutUp , fadeOutLeft,...)

动效延时: data-wx-wow-outDelay [默认与 data-wx-wow-delay 相同 ] ( 300ms , 0.3s, 4s ...)

动效持续时间:data-wx-wow-outDuration [默认与 data-wx-wow-duration 相同 ] ( 300ms , 0.3s, 4s ...)

动效执行次数: data-wx-wow-outIteration [默认与 data-wx-wow-iteration 相同 ] ( 1, 5, infinite, ...)

设置页面重复动效 (进入页面重新刷新执行动效)

Page({
   data: {
      wxwowConfig: {
          repeat: true //是否重复刷新开启动画 默认 true , 当设为 false,则该页面未销毁前,只会执行一次动效
      }
   }
})

其他设置

设置某单个动效,重复执行(优先级高于设置页面重复动效),给 类名 class 加入 wxwow-repeat
  <view class=" {{wx.WOW()}} wxwow-repeat " data-wx-wow-name="bounceInUp" data-wx-wow-id="{{wx.WOWId()}}"  catchtap="{{wx.WOWOut}}" > ... </view>
设置某单个动效,仅仅执行一次(优先级高于设置页面重复动效),给 类名 class 加入 wxwow-once
  <view class=" {{wx.WOW()}} wxwow-once" data-wx-wow-name="bounceInUp" data-wx-wow-id="{{wx.WOWId()}}"  catchtap="{{wx.WOWOut}}" > ... </view>
