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 🙏

魔改的vue keep-alive组件,支持通过key的形式缓存组件

Readme

功能描述:

由于vue内置的keep-alive组件通过name值进行缓存,当存在一个组件被创建了多次,需要根据不同的key来缓存组件时就不好做了,因此魔改了一下内置的keep-alive组件,使其可通过设置唯一key来缓存同一组件。

适用版本:vue2.x、vue3.x

使用方法:

1.安装依赖

npm i vue-keepalive-by-key --save

2.引入组件

import KeepAlive from 'vue-keepalive-by-key'

3.注册组件(推荐全局注册以覆盖内置keep-alive组件)

Vue.component('keep-alive', KeepAlive)

4.vue2.x使用示例(注意给keep-alive包裹的组件设置唯一key,如$route.fullPath)

<keep-alive>
    <router-view :key="$route.fullPath"></router-view>
</keep-alive>

5.vue3.x使用示例(注意给keep-alive包裹的组件设置唯一key,从useRoute中取fullPath也可)

<router-view v-slot="{ Component }">
    <keep-alive>
      <component :is="Component" :key="" />
    </keep-alive>
</router-view>

6.其他使用与内置keep-alive组件一致
