This article describes how to quickly get started with the application development of Django and React/redux SPA (Single page Web application: one Web application). It's hard to imagine a Django application without user authentication and authorization. So we start with a simple application that validates a user and executes an authorization request to the API. In addition, you will

performance. To make it more efficient, you can add immutable. js. 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: V.

The React navigation is returned by default using key as the GoBack parameter, which is generated dynamically rather than the routename we define. There are many ways to change the source code, some say it is integrated redux. How to change the source code I tried too, but if you turn on the swipe back property, it's easy to get stuck. Integrated Redux is a goo

async/await Async/await is a new feature of the ES7 standard that has not yet been officially announced. In short, you'll want to write asynchronous code in a synchronized way. For the front-end, the writing of asynchronous task code has gone through the callback to the current Promise and will eventually evolve into async/await. Although this feature has not yet been officially released, the use of Babel Polyfill we can already use it in the application. Http://www.tuicool.com/articles/B77zAbe

React-redux provides two key modules: provider and connect. Provider Provider This module as the entire app container, in your original app container on the basis of a layer, it is very simple to accept the Redux store as props, and declare it as one of the properties of the context, which can be conveniently accessed to the store via This.context.store after
