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 🙏

Redux繁琐模板写法解决方案

  1. 你是否遇到过,在使用redux时频繁在action(actionType),reducer,saga中来回切换文件。
  2. 你是否遇到过,需要完成一个小小的功能,却需要创建至少三个文件action``reducer``saga
  3. 你是否遇到过,整天纠结到底是应该为了避免繁琐,直接将相关业务直接写在组件中,还是为了分层解耦,不耐烦的创建一个又一个模板文件。
  4. ...

解决方案构思

  • Redux本身函数式编程风格带给我们的是代码足够的简单,没有任何的黑魔法,完全就是一个一个的纯函数,基于此特性决定不更换Redux本身。
  • 在学习Redux文档的过程中,有一节讲的是缩减样本代码,受此文章的启发,决定尝试能不能根据配置生成需要的action``reducer``saga
  • 对比模板文件发现action本身可以不存在,只是为了将各个地方的代码联系起来,方便代码阅读和维护,基于此可以考虑直接使用一个方法生成actionreducer
  • 同时为了集成saga,又不破坏原有的耦合特性,故采用约定大于配置,在action的方法名前加_的方式。
  • 在尝试过程中发现为了所需的配置模板的风格与Dva甚是相似,怀疑过是不是与Dva的功能重复,期间学习过Dva的代码,发现还是出发点不一样。
  • 本解决方案没有任何的黑魔法,只是换了一种代码组织方式,将action``reducer``saga的功能集中于一处,不需要任何的附加api学习成本。

Installation

  • Using npm: npm install redux-template --save
  • Using Yarn: yarn add redux-template 模板

Example

创建配置

@注: 使用ts及class是为了代码提示方便,如果不需要可参考js版

import {creator, BaseConfig} from "./reduxFactory";

class Test extends BaseConfig {
  namespace = 'test';

  initState = {
    num: 1
  };

  add = (payload: {
    number: number
  }, state?: any) => {
    return {
      num: state.num + payload.number
    }
  };

  _add = function *() {
    yield console.log('啦啦啦');
  };
}

export default creator<Test>(new Test());

使用配置

// reducer
import { combineReducers } from 'redux'
import Test from "../Test";

export default combineReducers({
  test: Test.reducer
})

// saga
import {all} from "redux-saga/effects";
import Test from '../Test';

export default function* () {
  yield all([
    Test.saga()
  ]);
};
