property items, array type, of course, can be called other names.2,aitems's first argument state=, why would you let state assign an array type? Shouldn't it be an object? This is because in assigning to Todos the sentence, items:aitems, I understand this point is when the trigger event, Redux will automatically traverse Todos, and then the state and Combinereducers in the object to compare, encountered the same name property, Pass the same name at
My own understanding redux is similar to the Vuex in Vue, is a data manager, say, we start from the classic counter case to explain
Implementing counters using Redux

The previous article shows the basic use of redux, you can see Redux is very easy to use, not limited to react, can also be used in angular, Vue and other frameworks, as long as the need to redux the design of the idea of the place, you can use it.This article mainly explains the use of

React such a popular framework is not introduced, Redux is a small frame of a single data flow, of course, not only with react, it was originally for the react, and now for all, such as Ng-redux project. Redux as the standard coll
began to learn react, on the Internet to find some articles, read the official website of some documents, then feel react started or quite simple,
and then on the Internet to find a react actual combat practicing project, personally learned that this project is suitable for beginners or advanced friends
Practice, here to share with you
React-redux principle analysis written in frontPreviously wrote an analysis of the Redux in the store implementation of the article (see: Redux Principle (a): Store implementation analysis), suddenly realized, in fact, react and Redux
If you pretend to be forced, please take me to fly!Once upon a time, I heard that react only responsible for the UI, saying that angular code is like writing back end, now it seems, react win in the feelings;I think there is no need to always compare react and angular, angular is a relatively complete set of chatty framework, and
As we all know, one of react's pain points is communication between components that are non-parent-child, and its official documentation is not taboo:
For communication between, there is a parent-child relationship, you can set up your own global event System. Subscribe to events in Componentdidmount (), unsubscribe in Componentwillunmount (), and call SetState () when you receive an Event.
Redux can be seen as the "global Event System",

The core code is as follows:
The store object stores the application status and provides some help methods to access the status, distribution status, and registration listening. All States are represented by one store. Any action returns a new State object through CER Cer. This makes Redux very simple and predictable.
The core code is as follows:
I. Definition and functionReact-redux divides all components into two main categories: UI components (presentational component) and container components (container component)1. UI Component Features:
Only responsible for UI rendering, without any business logic
No state (i.e. not using this.state this variable)
All data is provided by parameter ( this.props )
Do not use any of the Redux
The mainstream data Flow framework: Flux/reflux/redux
Simple/single State tree
All actions of the user are distributed to several stores by a unified dispatcher
This store holds data that also holds a state of the current page and can only pass information back to the view layer.
The Reducer store is responsible for distributing action, responding
