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 🙏

Readme

Proxima应用间通信

通过@nebulare/data来实现,目前支持状态共享store和事件监听响应event两种方式

安装

yarn add @nebulare/data

or

npm install @nebulare/data --save

store

API

  • get(key) 从store中根据(key: string | symbol)获取变量值
  • set(key,value) 根据(key: string | symbol | object)设置store中的变量值
  • has(key) 检查插件该变量是否有变量监听事件
  • on(key,callback,force) 注册变量监听事件,(force: boolean),为true时,在注册过程中会执行一次callback
  • off(key,callback) 删除已注册的变量监听事件
  • clean(Array<key>) 删除变量的值和删除变量监听事件

示例

获取/修改 当前用户信息

// 主应用
import { store } from '@nebulare/data';

const userInfo = { name: '蒜香骨发烧友', age: 18 };
store.set('user', userInfo); // 登录后设置当前用户信息

// 子应用
import { store } from '@nebulare/data';

function showUser(userInfo) {
  console.log('current user', userInfo);
}

// 获取当前用户信息
store.get('user');
// 监听当前用户信息变化
store.on('user', showUser, true);
// 是否有变量监听事件
store.has('user') // true
// 删除监听当前用户信息变化
store.off('user', showUser, true);
// 删除变量的值和删除变量监听事件
store.clean(['user']);

Event

Api

  • on(key,callback) 注册回调函数
  • off(key,callback) 删除回调函数
  • emit(key,...args) 触发已注册的回调函数,支持传参

示例

主应用有刷新当前列表入口,子应用内有执行函数,执行完函数后需要通知主应用刷新当前列表

在主应用监听事件

// 主应用
import { event } from '@nebulare/data';

event.on('refreshList', () => {
  // 刷新当前列表
});

在子应用触发事件

// 子应用
import { event } from '@nebulare/data';

event.emit('refreshList');
