This is a post that tries to explain the the basics of Redux. We’ll build a minimal working example with Redux. If you’re looking for proper Redux documentation then check official docs. What is Redux From the official docs - Redux is a predictable s…

The first things we need to do is create a reducer: /** * CONSTANT * @type {string} */ export const GET_CATEGORIES = "GET_CATEGORIES"; /** * INIT VALUE */ export const initialCategories = [ {id: , name: 'Development'}, {id: , name: 'Design'}, {i…

React-Redux Introduction React-Redux is a library for React based on Redux package. And the core idea of React-Redux is to separate the state from the pure components, thereby achieving the purpose of centralized management. For example, there is a r…

How to dispatch a Redux action with a timeout? Q I have an action that updates notification state of my application. Usually this notification will be an error or info of some sort. I need to then dispatch another action after 5 seconds that will ret…

As I am sure you have heard a bunch of times, by now, React is the V in MVC. I think you can think of Redux as the M. Really, React + Redux kind of also act as the C. So, you could just manage your state directly within your React components, and in…

背景 我一个前端,今年第一份工作就是接手一个 APP 的开发...一个线下 BD 人员用的推广 APP,为了让我这个一天原生开发都没有学过的人能快速开发上线,于是乎就选择了 react-native 作为开发框架,既然主框架有了,接下来就是主要的逻辑框架的选择了. 一直以来社区里面关于 react 的状态管理都是推荐 Flux 思想的实践者 Redux ,关于这个 Redux 国内已经有了很多很多的分析和讲解了,自然资料也是最多,坑最少的选择了,所以这次的开发便选择了 Redux 全家桶来作为整…

配合源代码学习吧~ : 我是源代码 这一分支讲的是 如何完整地(不包含优化,也没有好看的页面) 搭建一个 增删改查 的 react-redux 系统 不同于上一节的 react-redux,这里主要采用 函数式组件. 函数式组件 = 函数式的写法 + 不需要state的组件. 其实函数式组件也就那么回事. 如果组件本身 没有需要 维护的 state,我们就可以使用 函数式组件. react-redux 的一部分难度来源于 connect,其实它就是一个... 高阶函数!就是我们上一节说的. 作用…
