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 🙏

七鱼基础组件包

七鱼基础组件包, 基本思想以插件的方式开发。

插件规范

Vue的插件应当有一个公开方法 install。


    MyPlugin.install = function (Vue, options) {
      // 1. add global method or property
      Vue.myGlobalMethod = ...
      // 2. add a global asset
      Vue.directive('my-directive', {})
      // 3. add an instance method
      Vue.prototype.$myMethod = ...
    }

插件列表

|插件文件 |插件功能| 备注 | |:---|:---|:---| |cache.js| 提供基于NEJ-Cache的缓存机制| 中间者模式| |sailfish.js|基础UI插件集合|提供指令, 过滤器和混合的集合|

指令规范

所有的钩子函数将被复制到实际的指令对象中,钩子内 this 指向这个指令对象。

    Vue.directive('my-directive', {
      bind: function () {
        // 准备工作
        // 例如,添加事件处理器或只需要运行一次的高耗任务
      },
      update: function (newValue, oldValue) {
        // 值更新时的工作
        // 也会以初始值为参数调用一次
      },
      unbind: function () {
        // 清理工作
        // 例如,删除 bind() 添加的事件监听器
      }
    })

过滤器规范

过滤器接收两个参数:过滤器 ID 和过滤器函数。

    <!-- 任意参数 -->
    <span v-text="message | wrap 'before' 'after'"></span>

    <!-- 动态参数 -->
    <input v-model="userInput">
    <span>{{msg | concat userInput}}</span>
    // 传入任意数量的参数
    Vue.filter('wrap', function (value, begin, end) {
      return begin + value + end
    });

    // 双向过滤器
    Vue.filter('currencyDisplay', {
      // model -> view
      // 在更新 `<input>` 元素之前格式化值
      read: function(val) {
        return '$'+val.toFixed(2)
      },
      // view -> model
      // 在写回数据之前格式化值
      write: function(val, oldVal) {
        var number = +val.replace(/[^\d.]/g, '')
        return isNaN(number) ? 0 : parseFloat(number.toFixed(2))
      }
    })

    // 动态参数
    Vue.filter('concat', function (value, input) {
      // `input` === `this.userInput`
      return value + input
    })
