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-data-center

将vue页面中的一个组件作为数据中心使用

将某个组件对象暴露给他的所有子组件(要暴露的组件作为一个数据中心而存在)

Installation

npm install vue-data-center --save

使用方法

安装datacenter

import DataCenter from 'vue-data-center'
Vue.use(DataCenter);

定义datacenter组件
要暴露的对象的data上需要定义 isDataCenter: true

引用datacenter组件
this.$dc

示例:

在页面入口js安装

import DataCenter from 'datacenter'  
Vue.use(DataCenter);  

在要作为数据中心的组件中定义isDataCenter字段,值为true

export default {
  data() {
    return {
      isDataCenter: true
    }
  }

在子组件中引被暴露的对象的方式为

this.$dc

如果没有组件定义了isDataCenter字段、或者引用了数据中心组件上未定义的字段,则会在控制台上提示错误

可以让$dc不返回DataCenter上的真实函数,取而代之为一个空函数。当所有的状态修改都是通过DataCenter上的函数实现时,该功能可以禁用所有的状态修改

import DataCenter from 'vue-data-center'
Vue.use(datacenter);
DataCenter.returnNoopFun(true);
