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 🙏

Install

npm install @sdp.nd/redux-async-promise --save

Adding as middleware

import asyncPromiseMiddleware from 'redux-async-promise';
let createStoreWithMiddleware = applyMiddleware(
  asyncPromiseMiddleware({
    // 用于控制是否派发 globalLoadingActionType, 默认值,每个 action 可以在 meta 里面覆盖
    showLoading: true,
    // 全局 actionType 后缀,分别表示三个状态 pending, success, error
    actionTypeSuffixes: ['PENDING', 'SUCCESS', 'ERROR'],
    // 全局 loading action type
    globalLoadingActionType: 'RECEIVE_LOADING_STATE',
    // 全局提示消息 action type
    globalMessageActionType: 'RECEIVE_GLOBAL_MESSAGE',  }),
)(createStore)

Usage

// action-creators.js
import { createAction } from 'redux-actions'
import { $inject } from 'redux-async-promise';

function getPropE(propD) {
  return Promise.resolve(propD)
}

export var fetchXxxxx = createAction('Xxxx',
  // payload
  options => ({
    propA: new ModelA.GET(), // a promise
    propB: new ModelB.GET(), // a promise

    propC: $inject((propA, propB) => {
      console.log(propA, propB)
      return Promise.resolve(propA)
    })('propA', 'propB'),

    propD: $inject(propC => Promise.resolve(propC))('propC'),
    
    // uglifyjs压缩导致依赖丢失的,可以使用$inject来显示注入参数
    propE: $inject(getPropE)('propD')
  }),

  // meta
  options => ({
    propA: {
      // 单个请求 types, success, error 处理
      
      // 声明异步请求的 actionTypes,['PENDING', 'SUCCESS', 'ERROR'],可以在 reducer 中处理
      types: [], 
      onSuccess(resonpse) {},
      onError(resonpse) {}
    },
    // 全局处理对象
    finalProcess: {
      success: {
        showHint: true/false.
        text: '请求成功',
        handler: (response) => {
          // Do something with response
        }
      },
      error: {
        showHint: true/false,
        text: '请求失败', // text 未指定则使用服务端返回的错误信息
        handler: (response) => {
          // Do something with response
        }
      },
      complete(action) {
        // 异步请求结束处理函数
      }
    }
  })
)
