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 🙏

设计概要

ppx(皮皮虾)是一个遵循flux思想的数据管理工具。

  • one store 原则 不同于redux, 我们摒弃reduce 的设计,改用了model的思想,考虑到model与view存在多对多的情况, 统一由一个store管理
  • suport middleware 与redux类同,也支持中间件,因为考虑到异步的缘故,目前是与redux的中间件不同,后期考虑支持redux中间件
  • promisefy 支持promise,不仅是model支持异步,而且中间件也支持异步
  • suport react 依然是flux的思想,那么支持react是必然的,后期考虑支持vue等其他的库
 npm install --save ppx

接入说明

model引用

    import Store from 'ppx';
    class App {
        constructor() {
            this.state = {
              a: 1,
              b: 2
            };
        }
        test(state, action){
            return {
                ...state,
                aciton.test
            }
        }
        post (state, action){
            return Ajax(action.url).then(function(rep){
                return {
                    ...state,
                    a: rep.a
                }
            })
        }
    }
    Store.model(App);

middleware引用

    import Store from 'ppx';
    var middleware = (next, action)=>{
      console.log('plugin start:', action);
      const data = await next(action);
      console.log('plugin end:', data);
      return data;
    }
    Store.use(middleware);

view 调用

import React from 'react';
import {connect} from 'ppx';

class Test extends React.Component {
  constructor(props) {
    super(props);
  }

  handleAdd(e) {
    const {dispatch} = this.props;
    dispatch({type: 'app/add'});
  }
  handleDel(e) {
    const {dispatch} = this.props;
    dispatch({type: 'app/minus'});
  }

  render() {
    const {page} = this.props;
    const {a} = page;
    return (
      <div>
        <p>a: {a}</p>
        <a onClick={this.handleAdd.bind(this)}>增加</a>
        <a onClick={this.handleDel.bind(this)}>减少</a>
      </div>
    );
  }
}

export default connect(['App'])(Test);

todo:

  • 当一个view绑定多个model时 是否需要默认model
  • reduce中是存在多种返回时:比如请求当成功时给成功提示,失败给失败提示,但是有使用失败给成功结果,失败提示, 目前初步定为用中间件去解决这类问题
  • subscribe 性能调优

感谢:

  • 感谢 darrenscerri 提供的异步中间件思路
  • 本库的flux思路类似于dva, 只是有别与dva的redux与redux-saga的思路 ppx使用更加简单
  • 感谢离职同事的贡献,所以本库任性的按照他的绰号取名
