Preliminary study on the use of React native February 06 2015Facebook lets all react conf participants get a taste of react native's source---a way to write native mobile apps. This method uses all the powerful features of React.js to apply it to native applications. You can write JavaScript-based components by using t

This is the directory structure of the project, the main code is in the SRC directory, src below a new containers folder put some of our components, router folder is configured for routing.

Learning react just started, intend to use Nodejs+react+mysql to build a personal blog, the original plan is to the left to achieve a navigation bar click to switch from the background to get content to render.
As a result, when you write the index entry file, you suddenly realize that Nodejs routing first distributes HTTP requests to different logical modules to process and then returns the corresponding c

BeforeUpdate: Can hear the change of data but the view layer has not been re-rendered, the view layer of data has not changed
Between BeforeUpdate and update: When Vue discovers that data has changed, it triggers a re-rendering of the corresponding component (re-renders the virtual DOM, and updates the real DOM with the diff algorithm to compare the Vnode node

Complex logic componentsIt is difficult to develop and maintain. When our components need to process multiple irrelevant local states, each lifecycle function may contain various irrelevant logics.

well, it's easy to deal with the properties and states of the underlying type, and we can implement a mix and inject it into all the components directly using the comparison provided by the JS language, === in fact, react itself has provided a similar: Purerendermixin.But what if your component has a property or state that is not the underlying type, but a composite type? For example, a JS object {foo: ‘ba

If you have completed your previous article and successfully debugged the first "Hello World" project, you have successfully taken the first step and the next study will be much smooth
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

1. What is React-native?
React-native: Facebook unveiled an open source project at the React.js Technical symposium in early 2015. Support for developing iOS and Android native apps with open source JavaScript library react.js. Initially only iOS platform support, the same year September, the Open source project also supports the Android platform.
The principle of
React, from Facebook, is a very good class library for creating user interfaces. The only problem is that React doesn't focus on how your app handles data. Most people treat React as V in mv*. So, Facebook introduces a pattern called Flux that provides a functional channel that can be used for in-app data processing. This tutorial briefly introduces the Flux patt
solution, many places also need to supplement, this has made the technical ability of the team requirements, and the ANGUARJS framework is relatively perfect, suitable as the overall front-end development solution for use, suitable for large-scale engineering development. As for Angularjs 2, wait until the browser can generally support ES6 time to consider it.personal feeling behind relay will gradually replace flux. Relay is a new framework for Facebook's first public debut on React.js Conf (J

Okay, the problem is clear. Dude, I hope some of my big Masters can set up a super-talented developer group to really solve this problem...Embracing Facebook's React
It turns out that they did. React implements a virtual DOM, a powerful weapon that brings us the Holy Grail.What is a virtual DOM?

This is all the APIs for a react component. You have to have a rendering method. It's complicated, huh?
OK, butWhat is the meaning? That's not JavaScript! Yes, it's not.
Your new partner, JSX.
This code is actually written in JSX, a superset of JavaScript that contains syntax for

How to use it?PurerendermixinREACT provides us with purerendermixin for the first question. If the react component is purely functional, the same UI is presented for the same props and state components

React. js is positioned as "A JavaScript Library for building user interface". Its documentation says many people use it as mvc v. Therefore, React. js does not care how you embed backend data. In other words, we can apply the same idea to the components created by React. js by usin
