Why should we even bother with reactive programming? Well, we all do care about writing testable, loosely coupled code, but are our dependencies really loose? Imagine that you have a working piece of code implementing particular business logic, and you would like to connect a new feature into the flow. If your code isn't reactive yet, you would have to add more "if-ology" to it, causing you to have to change the existing code base - that is not what I believe loosely coupled dependencies look like. How can the reactive, unidirectional Flux pattern help?
Isomorphic apps are almost like “normal” apps when creating them with the FRP. Because the FRP encourages you to always pass the entire state object to the rendering function, nothing prevents you to do the same in the backend as well.
If you have read other tutorials you may already know that React has a “backend-compatible” function called renderToString. It behaves exactly like render but doesn’t call componentDidMount and returns the rendered HTML as a string instead of placing it into a DOM node. Component & model in → HTML out. Couldn’t be simpler?
Well… actually, it could be. There are two gotchas you should know before trying to use renderToString:
- - Your backend must understand JSX syntax - Your front-end modules must be CommonJS compatible

One of the many benefits of React is its ability to render components on both client and server. This tutorial aims to teach you how to create isomorphic apps using React and Flux architecture. We will also create a simple blogging app to understand how exactly Flux and React fit together.
I’m going to share how we transitioned to Flux and give some insight into why each part of the architecture is valuable. I’ll also show a couple examples similar to real problems we faced here at Kapost. I do assume the reader has some knowledge of React, a rough idea of what Flux is, and doesn’t mind reading a lot of code. If you are unfamiliar with React and Flux, check out the React documentation and the basic introduction to Flux. (Unfortunately the Flux docs are like a shoddy professor—giving a vague lecture and basic example, then running off and expecting you to solve the hard problems with no office hours.) I’ll try to explain the parts in more detail below.
We are building a new email app using React, Flux, and Electron with a primary goal of extensibility. Over the past few months, we've designed a new way to structure large React applications in order to reliably and safely support plugins.
React in a way, resembles Angular directives but that’s all there is: these directives. In React, they’re called “Components”. When creating a component, certian methods are run (if available). The main one is render which uses data that React exposes (like state, props, etc. more on that later) and uses it to build a fake DOM using “JSX”.
The beauty of ReactJS is its one-way flow which is easier to follow and understand. There is no $digest nor any way to setup $watch. But let’s look at all the cool things about React first:...
In our fast-changing world, technology is rapidly taking giant leaps forward. For the people who are just beginning to take part in this new “gold rush” of web development, it is sometimes inevitable to feel a sense of desperation of not being able to keep up with the evolution. In this article, I will attempt to give a brief overview of one of the most-adored features of Facebook’s Reactframework—isomorphism(a.k.a. server side rendering).
“Many people that use ReactJS as their renderer are using some kind of theFlux architecture to store data, react to actions and notify componentsabout changes. After a University project involving Scala and RxJava, I wantedto use these ideas together with ReactJS views. Besides that I found two thingsmissing in the Flux architecture:composing different kinds of data easilyinteraction with the serverOf course there are ways to solve this, but perhaps reactive streams can helpease these shortcomings.”
