Build A Real-Time Twitter Stream with Node and React.js ― Scotch Introduction Welcome to the second installation of Learning React, a series of articles focused on becoming proficient and effective with Facebook's React library. If you haven't read the first installation, Getting Started and Concepts, it is highly recommended that you do so before proceeding. Today we are going to build an application in React using Isomorphic Javascript. Iso-what? Isomorphic. This is the concept behind frameworks like Rendr, Meteor & Derby. Why is this awesome? I'm an Angular fan just like everybody else, but one pain point is the potential SEO impact. But I thought Google executes and indexes javascript? Yeah, not really. Enter React. React is amazing on the client side, but it's ability to be rendered on the server side makes it truly special. Getting Started Alright gang, lets get down to brass tacks. Here is a quick look at what we'll be building. Let's take a look at some of the tools we are going to use besides React: Server Side Directory Structure package.json server.js
Reapp - Hybrid apps, fast What is it? Reapp is everything you need to build amazing hybrid apps with React: a collection of modules that work together, a UI kit, and our CLI that bootstraps your app and has a pre-configured build server. Examples We have two example apps you can check the source to: Installation Installation is done through npm, though you can pick and choose any pieces you'd like and roll your own stack. npm install -g reapp Once that's done you can generate a new base reapp stack with: reapp new [name] Where [name] is the name you'd like to give your new stack. The CLI has two main functions that it helps you with. It also lets you run your app, using reapp-server, a simple express server that works well with the default app structure. CLI Usage: Usage: reapp [options] [command] Commands: new [name] creates a directory with a new reapp-starter scaffold run runs a reapp application with express/webpack-dev-server build builds a reapp application to a bundle in .

Getting To Know Flux, the React.js Architecture ― Scotch Introduction Welcome to the third installment of the Learning React series. Today we will be learning about how Facebook's Flux Architecture works, and how to use it in your own projects! If you haven't already, I strongly recommend you check out the first two installments in this series, Getting Started & Concepts and Building a Real Time Twitter Stream with Node and React. What is Flux? Flux is an architecture that Facebook uses internally when working with React. That said, Facebook does provide a repo that includes a Dispatcher library. A typical Flux architecture will leverage this Dispatcher library, along with NodeJS's EventEmitter module in order to set up an event system that helps manage an applications state. Flux is probably better explained by explaining its individual components: Lets take a look at what this process looks like graphically: How does the API relate to this? The Dispatcher So what's this Dispatcher all about? So it's essentially pub/sub? Not exactly. Dependencies
5 Practical Examples For Learning The React Framework Martin Angelov You’ve probably heard about the popular JavaScript framework by Facebook – React. It is used by many popular websites, including Facebook itself and Instagram. What is special about React? React is built around the concept of components. However, the flip side is that it takes a bit more code in React to achieve the same things that can be easily done with a data binding, as you can see from the examples below. How to use it? To use React, you need to include a single JavaScript file in your page. This gives you access to the global React object, which holds a number of useful methods, some of which you can see in these examples. But enough talk, let’s see some code! 1. As I mentioned, the building blocks of react apps are components. (Click the JavaScript 1.7 link to see the JSX source code.) You can embed any JavaScript expression within braces {} when creating a component. 2. Let’s see how we can handle click events in React by building a navigation menu: 3. 4. 5.
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. 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 Our first step to architecting an application is defining what it should do. This is what our finished product should look like: This app is going to be purely client side, so we aren't going to need a server. app.js
javascript - Pros and Cons of Facebook's React vs. Web Components (Polymer) Building A User Interface with ReactJS | DiscoverSDK Blog In the midst of the night, I decided to highlight the features of a powerful Javascript library... React.js... while teaching you to build a user interface within a process. In my previous article on Javascript Frameworks, I have mentioned about React.js -- which is an open-source Javascript library used for building views that is rendered as HTML in your web browser. React provides views which can be used for any interactive graphics creation, including but not limited to, sidebars, tabs and most importantly: user interfaces. The React.js code is merged with your HTML code in the front-end side, so when you load the page on the browser, then it will automatically use the external libraries (as long as you put the reference to it in the start). React.js allows you to create rendering objects and graphics (i.e., widgets, UIs, etc.). React.js is maintained by Facebook, Instagram and the independent developers that participate in the development of React.js. Let's talk about its features <!
How React Components Make UI Testing Easy Testing back-ends is easy. You take your language of choice, pair it with your favourite framework, write some tests, and hit “run.” Your console says “Yay! Sure, test-driven development (TDD) is weird at first, but a predictable environment, multiple test runners, test tooling baked into frameworks, and continuous integration support, make life easy. Then Backbone got big. We all switched to front-end MVC. That’s because testing front-end code and UI components is kinda hard. It’s not so bad if all we want is to check that our models behave well. Write well-formed, isolated modules. That’s it. It used to be that running front-end tests was the hard part. In 2012, Vojta Jina released the Karma runner (called Testacular at the time). What more could we wish for? Front-End Testing Requires More Than Just Unit Tests But front-end code isn’t about manipulating data. Here’s what we want to be able to do: Testing UI Components with React React is the easiest way to achieve these goals. The Setup
Tutorial: Intro To React - React Edit on GitHub Before We Start# What We're Building# Today, we're going to build an interactive tic-tac-toe game. If you like, you can check out the final result here: Final Result. Try playing the game. Once you get a little familiar with the game, feel free to close that tab, as we'll start from a simpler template in the next sections. Prerequisites# We'll assume some familiarity with HTML and JavaScript but you should be able to follow along even if you haven't used them before. How to Follow Along# There are two ways to complete this tutorial: you could either write the code right in the browser, or you could set up a local development environment on your machine. If You Prefer to Write Code in the Browser# This is the quickest way to get started! First, open this starter code in a new tab. You can now skip the next section about setting up a local development environment and head straight to the overview. If You Prefer to Write Code in Your Editor# Help, I'm Stuck!
