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 🙏

组件通讯

A组件 =》
export default {
  name: 'Test',
  luoOptions: {
    transmits: {
      xxxx (va) {
        this.aa += va;
      }
    }
  },
  mounted () {
    this.events.$emit('zzzz', 1);
    this.events.$emit('xxxx', 1);
    this.events.$emit('kkkk', 1);
  }
}

B组件 =》
<template>
  <div>
    <test key="t1"></test>
  </div>
</template>

import Text2 from '@/views/Test2';
export default {
  name: 'Test',
  luoOptions: {
    transmits: {
      zzzz (va) {
        this.aa += va;
      }
    }
  },
  mounted () {
    this.events.$emit('zzzz', 1);
    this.events.$emit('xxxx', 1);
    this.events.$emit('kkkk', 1);
  }
  components: {
    test: Text2
  }
}

C组件 =》
export default {
  name: 'Test',
  luoOptions: {
    transmits: {
      kkkk (va) {
        this.aa += va;
      }
    }
  },
  mounted () {
    this.events.$emit('zzzz', 1);
    this.events.$emit('xxxx', 1);
    this.events.$emit('kkkk', 1);
  }
}

vuex使用

一:testnpm.js
export default {
  namespaced: 'testnpm',
  cache: true,                // 可选(默认为不缓存)
  state: { 
    aa: 222
  }, 
  mutations: {
    xxx (state, va) {
      state.aa += va;
      // commit('account/login')
    } 
  },
  actions: {
    login ({ dispatch, commit }, va) {
      // dispatch('account/login')
    } 
  },
  getters: {
    
  },
  modules: {
    myPage: {
      state: {
        ma: 1,
      },
    },
    posts: {
      namespaced: true,
      state: { 
        mb: 2,
      },
    }
  }
}

二:组件内使用
export default {
  name: 'Test',
  luoOptions: {
    stores: ['@/store/testnpm', '@/store/test2'],
  },
  mounted () {
    console.log(this.$store.state.testnpm);
    this.$store.commit('testnpm/xxx', 1);
    this.$store.dispatch('testnpm/login', 2);
  },
  computed: {
    ...mapState('testnpm', {
      a: state => state.aa,
    })
  },
}

页面缓存(路由缓存)

const {MyPlugin, store} = creatNextVue({
  route: {
    routeKey: 'cachePathData',
    cacheFixedPathsData: ['/test1', '/test2', '/testnpm'],
    chacheChangePathsData: ['/fdsafdaf'],
  }
});

Vue.use(MyPlugin);

new Vue({
  el: '#app',
  router,
  render: h => h(App)
});

如何获取组件缓存(同一路由树下有效)

export default {
  name: 'Test',
  mounted () {
    var stateCache = this.$LuoGetStateCache(); 
    console.log(stateCache);
    var stateCacheB = this.$LuoGetStateCache('Test2'); 
    console.log(stateCacheB);
    var stateCacheC = this.$LuoGetStateCache('Test3', 'key'); 
    console.log(stateCacheC);
    var stateCacheD = this.$LuoGetStateCache('Test3', 'key', '/home/page'); 
    console.log(stateCacheD);
  }
}

如何获取vuex缓存

export default {
  name: 'Test',
  mounted () {
    var storeCache = this.$LuoGetStoreCache();
    console.log(stateCache);
  }
}

如何获取指定组件

let component = this.$LuoFindComponent('Test');

如何获取指定父组件

let parent = this.$LuoFindParentsComponent(this, 'Test');

如何设置字符串对象

一:覆盖模式

let context = this;
let data = this.$LuoSetStringObject(context, 'a.b.c', 'hello');
console.log(this.a.b.c);
console.log(data);

二:叠加模式

let context = this;
let data = this.$LuoSplicStringObject(context, 'implemenData.exciting.dataB.calendarData', {test: 1, test2: 2});
console.log(this.implemenData.exciting.dataB.calendarData);
console.log(data);

提示和注意点

一:一定要设置组件的name属性才能使用,且第一个字母为大写
二:组件通讯时和使用组件缓存时,如果同一路由下有相同组件,一定要设置key属性,不然取到的缓存都是一样的,(示例如下)
    <template>
      <div>
        <test key="t1"></test>
        <test key="t2"></test>
      </div>
    </template>
三:组件通讯最好是在mounted及mounted之后进行
四:没有设置路由缓存的路由下,都可以获取组件缓存
五:vuex的缓存是全局的,包括路由跳转(如果想清除,可以用store.registerModule卸载),使用是自已确定的,要不要使用vuex缓存是自己确定,本页面如果没用vuex缓存,但是本页面又改变了store状态,也会存入到缓存中,其它页面用到此vuex模块时,用到的缓存是改变之后的状态
六:vuex模块文件一定要设置namespaced名称,使用时的格式是namespaced名+方法名,如:this.$store.dispatch('testnpm/login', 2);
七:vuex模块默认都是带命名空间的模块;
八:cacheFixedPathsData属性的值是固定的(实际是可以改变的,不推荐改变,),chacheChangePathsData里的路由可以包含在cacheFixedPathsData里,cacheFixedPathsData里的值也可以包含在chacheChangePathsData里,作用是可以动态的调整路由缓存,(暂时不提供动态设置的方法,因为时间关系,后续会提供)比如横向标签的使用
九:路由缓存如果是带参路由,要写全,如:
    cacheFixedPathsData: ['/test1/:aa/:bb/:cc', '/test2', '/testnpm'],
    chacheChangePathsData: ['/test2/:kk', '/fdsfdsf/:jj/:kk'],
十:缓存的data一定要在界面上使用过,不然获取不到缓存
十一:获取组件缓存只在同一路由树下有效
十二:本地缓存名(key),务必使用域名前缀+"__"开头,如域名是"http://www.taobao.com/alipay/"则名为"www__alipay",(切记)
