We will learn how to start a Redux app with a previously persisted state, and how it merges with the initial state specified by the reducers. The initial state of store is defined by the rootReducers: const todoApp = combineReducers({ todos, visibili…
For example we have a component, it needs to call 'react-redux' connect function. import { compose, curry, option, propPath } from '../js/helper' const FilterButton = ({ active, onClick }) => { const classes = classnames('filterButton', { 'filterButt…
If you have props and actions, you want one component to access those props and actions, one solution is pass those from parent to this component. But one problem for this solution is if the there are many nested component between, you need to pass t…
With a well defined demarcation point between Redux and our State ADT based model, hooking up to a Redux store is no different than any other Redux based implementation. Once we have all of our transitions represented in dispatchable actions, we can…
Not only will we need to give our initial state to a Redux store, we will also need to be able to reset our state at any time by dispatching an action. We can get the best of both worlds by having a function that will return an object with all of our…
With our Redux implementation lousy with State ADT based reducers, it is time to hook it all up to a React Shell. Having already built out some UI/UX in React that is connected to our store, we’ll spend the first part of this lesson with a quick tour…
By using the State ADT to define how our application state transitions over time, we clear up the need for a some of the boilerplate that we typically need for a solid Redux integration. We can keep our action names and creators in the same file as t…
For example, current we have those todos: { todos: [ { completed: true, id: 0, text: "Learn Redux" }, { completed: false, id: 1, text: "Go shopping" }], } And now what we want to do is add a 'visibilityFilter' prop to the object, compo…
https://github.com/reduxjs/redux 版本 4.0.0 先了解一下redux是怎么用的,此处摘抄自阮一峰老师的<Redux 入门教程> // Web 应用是一个状态机,视图与状态是一一对应的 // 所有的状态,保存在一个对象里面 // store 是保存数据的地方 // 创建 store import { createStore } from 'redux' const store = createStore(fn) // state 是某一时刻 store 的快照…
今天看了下Redux的源码,竟然出奇的简单,好吧.简单翻译做下笔记: 喜欢的同学自己可以去github上看:点这里 createStore.js import isPlainObject from 'lodash/isPlainObject' import $$observable from 'symbol-observable' /** * These are private action types reserved by Redux. * For any unknown actions,…
运用redux有一段时间了,包括redux-thunk和redux-saga处理异步action都有一定的涉及,现在技术栈转向阿里的dva+antd,好用得不要不要的,但是需要知己知彼要对react家族有一点源码上的深入了,就从redux开始吧. redux源码是那么简洁.清晰.干净,让我忍不住一口气全部看完了还意犹未尽的写一篇随笔,mark一下,过段时间回头再重新细细评味学习一波.原谅我把整片代码贴出来,因为我懒啊,我会尽量把代码注解写详细一点. index redux对外暴露出的api,…
