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 🙏

vue-sticky

工作在 Vue2 的 sticky 功能。

目前的局限:

  • 在一个容器内,只能正确处理一个 v-sticky 的元素
  • 仅支持贴在顶部

使用

sticky 提供了指令和组件两种使用方式:

  • v-sticky 使用指令 import {sticky} from '@wangankeji/vue-sticky' 注意这里是小写

  • <sticky> 使用组件 import {Sticky} from '@wangankeji/vue-sticky' 注意这里是大写

  • Sticky 大写表示引入组件 (推荐用法)

  • sticky 小写表示引入指令

通常情况下,不建议直接使用指令。

属性

const props = {
  zIndex: {
    type: Number,
    default: 1
  },
  delay: {
    type: Number,
    default: 100
  },
  offsetTop: {
    type: Number,
    default: 0
  },
  offsetLeft: {
    type: Number,
    default: 0
  },
  offsetWidth: {
    type: Number,
    default: 0
  },
  // 是否应用了 css animation
  animation: {
    type: Boolean,
    default: false
  },
  disabled: {
    type: Boolean,
    default: false
  }
}

事件

指令的事件 change 会在使用此指令的组件上触发,如:

<template>
  <div>
    <div v-sticky>
      ...
    </div>
    <div>
      ...
    </div>
  </div>
</template>

<script>
import {sticky} from '@wangankeji/vue-sticky'

export default {
  name: 'ComponentA',
  directives: {sticky},
  mounted() {
    this.$on('change', ({attached, element}) => {})
  }
}
</script>

而组件的事件在 sticky 组件上触发。

<template>
  <sticky @change="onStickyChange">
    <template v-slot:sticky="{attached}">
      ...
    </template>
    <template v-slot:default="{attached}">
      ...
    </template>
  </sticky>
</template>

<script>
import {Sticky} from '@wangankeji/vue-sticky' 

export default { 
  components: { Sticky }
}
</script>

此事件有一个参数,其结构如下:

e = {
  attached: true, // 状态,值为 true/false
  element: '<HTMLElement>' // 当前的元素 
}
