Redux best practices — Lexical Labs Engineering. Redux is the React framework that other flux frameworks recommend you use. It went 1.0.0 when I started writing this (and is at the time of publishing past 3.0.0!) And it’s still early days as to how to use it. Its author, Dan Abramov, has put together some great documentation, but it doesn’t yet fully address how to deal with engineering with Redux at scale — people are starting to ask, “are there any repos of non-trivial apps that use redux”.

Well, hopefully this goes somewhere to it. We’ll talk about: the full tech stackwhat each part of Redux ends up doinghow to lay out a Redux projecthow to handle async data with WebSockets. What should I know already? Read the redux documentation. You should have read Dan’s article about Smart & Dumb Components. What tools do you need for a Redux project? Redux isn’t just Redux.

Your tool kit will probably contain most of the following: How do you use the different parts of Redux? We all know the story about Flux being a unidirectional data framework. Testing in React: Getting Off The Ground — JavaScript Inside. A first look: the Low Level Approach Let’s start with a low level approach by using the React specific Test Utils.

Test Utils enables a concept called shallow rendering, which simply means rendering a component one level deep, neglecting any child components. import TestUtils from 'react-addons-test-utils'; const renderer = TestUtils.createRenderer(); function shallow(Component, props) { renderer.render(<Component {...props} />); return renderer.getRenderOutput();} By implementing our own shallow function, we can simply call shallowRenderer internally and return a shallow rendered component. Now we can simply test a Bar component for example. const Bar = React.createClass({ render() { return ( <div className="bar">{this.props.title}</div> ) }}); Here’s our very first test, we want to make sure that the title passed in via props is being rendered.

This also explains why we can assert bar.props.ClassName to be ‘fooBar’ for example. Why shallow rendering? Enaqx/awesome-react. React.js Conf 2015 - Immutable Data and React. Christianalfoni WebApp Enthusiast. All standards, libraries, practices, architectures and patterns needs some time to evolve before becoming widely accepted. The flux architecture is no different. After Facebook released their React JS project the suggested flux architecture has evolved into many different shapes and colors. Some of them more accepted than others. In this article we are going to look at what challenges exists today with the flux architecture. We are also going to look at a solution that I think is a great contribution to the evolution of flux.

Flux and Flux history If you have never heard about flux before I will give a very short decription. Verbosity Developers in the JavaScript world have become accustomed to very expressive and easy to use API's. Async operations When you test your application it is better to do so if you can change the state of your store synchronously.

Handle the same action in multiple stores Facebook suggests a waitFor method that can reference the other stores in your application. Flux inspired reactive data flow using React and Bacon.js - Reaktor. A few years ago I got introduced to reactive programming and Bacon.js, a FRP (functional reactive programming) library for Javascript. I got fond of it very fast, as it allowed you to create highly reactive UI’s with ease. While it works great in propagating changes to your views, it was still rather cumbersome to attach all the data flows to individual DOM nodes and properties. React solved that problem completely. React makes the DOM reactive to your applications state, making your views predictable and declarative.

Flux is an application architecture commonly used with React. Flux architecture diagram (Source: Facebook) Mixin’ Bacon with React My goal was to make my React components update their state automatically when one of their underlying Bacon streams would update. In your typical Flux setup, you would have a single central dispatcher which would transport all actions from your action creators to your stores. Isomorphic applications Conclusion. React Native: Bringing modern web techniques to mobile. If you're new to React, you can read more about it on the React website. You can also get started with React Native for iOS, which was released at F8 2015 on the React Native website. It started with React We introduced React to the world two years ago, and since then it's seen impressive growth, both inside and outside of Facebook. Today, even though no one is forced to use it, new web projects at Facebook are commonly built using React in one form or another, and it's being broadly adopted across the industry.

Engineers are choosing to use React every day because it enables them to spend more time focusing on their products and less time fighting with their framework. It wasn't until we'd been building with React for a while, though, that we started to understand what makes it so powerful. React forces us to break our applications down into discrete components, each representing a single view. Why native is difficult Why native is necessary Best of both worlds? Using WebViews Open source. Material UI - Material Design React Components. Creating A Simple Shopping Cart with React.js and Flux.

Introduction Welcome to the fourth and final installment of the Learning React series! Up to this point, we've learned how React's API allows us to create rich stateful components, how to use them in practice & how Facebook's Flux architecture works. Today we are going to put all of it together to create a basic shopping cart application. In a typical e-commerce website, the product detail page has several moving parts that rely on one another and React really helps simplify and organize the co-dependency between them. If you haven't already, I highly recommend checking out the first three parts of this series: ReactJS 0.12 During the writing of this series, React released version 0.12 which made some fairly significant changes.

The /** @jsx React.DOM */ header is no longer required when writing JSX syntaxrenderComponent is now renderrenderComponentToString is now renderToString You can check out the entire changelog on the official blog post. Getting Started Directory Structure package.json. Building robust web apps with React: Part 1, in-browser prototypes | Matt Hinchliffe, Front-End Developer. Whenever I look into the internals of web browsers and the protocols that make the web work I usually end up feeling uneasy.

The number of parts that can and do go wrong makes it incredible that anything we build works at all. The against-all-odds robustness comes from the fault tolerance and backward compatibility engrained into key parts of web stack. The browser will always do its best to output something useful whether it’s parsing a badly authored document, unable to retrieve dependencies or 10 years out of date. I think this fundamental property of the web gets forgotten.

I worry when I see sites that make JavaScript the lynchpin of getting at content now and for the future. The additional complexity of the code we’re delivering and extra work we’re shifting into the browser means users might not get anything when even a small problem occurs. I’m not here to preach the philosophy of a luddite, I really don’t think we have to deliver plain HTML sites. Quick, in-browser prototypes. React. ReactJS для глупых людей. Пытаясь разобраться с библиотекой от Facebook ReactJS и продвигаемой той же компанией архитектурой «Flux», наткнулся на просторах интернета на две занимательные статьи: «ReactJS For Stupid People» и «Flux For Stupid People». Решил поделиться с хабравчанами переводом первой (а чуть позже и второй) статьи. Итак, поехали.TL;DR В течении долгого времени я пытался понять, что такое React и как он вписывается в структуру приложения. Это статья, которой мне в свое время не хватало.

Что такое React? Чем отличается React от Angular, Ember, Backbone и других? Остановитесь прямо сейчас. React — это ТОЛЬКО УРОВЕНЬ ПРЕДСТАВЛЕНИЯ. React дает вам язык шаблонов и некоторые callback-функции для отрисовки HTML. Разумеется, вы не можете построить полно функционирующее динамическое приложение только с React. Плюсы После работы с React, я увидел три очень важных преимущества. 1. Скажем, вам нужно изменить заголовок вашего сайта на имя пользователя после логина. Вот как вы могли бы сделать это с React: 2. 3. 1. Enaqx/awesome-react.
