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-propsync-mixin

vue-propsync-mixin:vue组件的混合对象,主要用于组件编写时混入调用。

【主要功能】

  1. 实现了在组件内自动创建所有prop对应的data属性,方便组件内修改prop使用。解决了vue2.0中数据单向流的问题
  2. 实现了子组件修改组件prop,组件内自动同步修改到父组件的data属性。

【使用方法】

  1. 编写组件:在选项对象中增加 mixins:[propsync]即可,无需其他修改
  2. 调用组件:在调用的组件上新增 .sync 属性

【可配置忽略】

  1. 默认情况下,调用了本mixin的组件,会实现组件定义的所有的props,创建对应data变量,绑定双向watch。
  2. 若希望某个props进行绑定,则可在那个props中增加 propsync:true(可配置),默认所有props均为false

调用组件例:

<!-- 父组件 -->
<template>
    <my-component :show.sync="show" />
</template>
<script>
    export default {
        data(){
            return {
                show:false
            }
        }
    }
</script>

<!-- 子组件 -->
<template>
    <div>
        <div v-show="sync_show">vue-propsync-mixin</div>
         <button @click="onClick">按钮</button>
    </div>
</template>
<script>
    import propsyncMixin from 'vue-propsync-mixin'
    export default {
        name:'MyComponent',
        mixins: [propsyncMixin],
        props: {
            show: {
                type: Boolean,
                default: false,
                propsync: true
            }
        },
        methods:{
            onClick(){
                this.sync_show = !this.sync_show
            }   
        }
    }
</script>
