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 🙏

data-cache

类似 keep-alive 的数据持久化组件

解决的问题

使用keep-alive缓存无法做到刷新画面也保持原样,而且进入画面时缓存如何单画面清理不是特别明白。

应用场景

进入画面时,调用方法clear方法清理掉缓存,直接刷新画面被缓存的数据被正常还原,进入下一个画面,返回上一页时,正确还原缓存。

CDN引入

<script src="https://cdn.jsdelivr.net/npm/@anywo/[email protected]/util/dataCache.umd.js"></script>
<script>
  Vue.use(vueDataCache);
</script>

全局引入

import dataCache from '@anywo/vue-data-cache';
Vue.use(dataCache);

局部引入

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  // ...
  mixins: [dataCache.mixin]
  // ...
};
</script>

例子

npm安装后,在node_modules文件夹中找到组件文件夹,内含demo。

Booble 传参

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  data(){
    return {
      text: '',
      value: '',
    };
  },
  dataCache: true, // 缓存data中的全部字段
  mixins: [dataCache.mixin]
};
</script>

Array 传参

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  data(){
    return {
      text: '',
      value: '',
    };
  },
  dataCache: ['text'], // 缓存data中的指定字段
  mixins: [dataCache.mixin]
};
</script>

Object 传参

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  data(){
    return {
      search: {
        text: '',
        value: '',
      }
    };
  },
  dataCache: {
    enabled: true, // 启动当前配置,如果混入中有配置,并且没有关闭,正常应用
    target: ["search"], // 要缓存的目标,默认:data的全部内容
    exclude: ["search.value"], // 缓存要排除的部分,search.text正常缓存,search.value不缓存
  },
  mixins: [dataCache.mixin]
};
</script>

dataCacheKey 一个画面多个组件需要使用缓存,可以使用此字段做区分

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  data(){
    return {
      text: '',
      value: '',
    };
  },
  dataCacheKey: "home", // 一个画面多个组件需要使用缓存,可以使用此字段做区分
  dataCache: ['text'], // 缓存data中的指定字段
  mixins: [dataCache.mixin]
};
</script>

clear

import dataCache from '@anywo/vue-data-cache';
<script>
export default {
  data(){
    return {
    };
  },
  methods:{
  	clear(){
  	  dataCache.clear(this.$route.path); // 清理指定画面
  	},
  	clearAll(){
  	  dataCache.clear(); // 清理全部缓存
	},
  }
};
</script>
