Without any modifications, React is really fast as-is. There are, however, a few things that you can do to improve performance. While working at HelloSign, I discovered some quick fixes that made our apps incredibly snappy. With these simple changes, I was able to reduce render time from over 3000 milliseconds to less than 200 milliseconds. Without any modifications, React is really fast as-is. Th
I’ve been back from Nodevember for two days now. I took a coworker with me who hasn’t used javascript in years. After the conference he’s been asking me non-stop on how to get started with React. This is aimed at people who understand javascript but have never used node. Even if you’ve used React quite a bit, this will help you understand Redux and give you a taste of ImmutableJS ###What this cove
ReactJS News!Editor’s Note: Please check out the React Indie Bundle. Juho and many other members of the React community help put it together. All of the proceeds go towards awesome people in our community. Programming is a bit like gardening. While trying to keep the bugs out, we prefer to keep everything neat and organized lest we want to end up in the jungle. A poor structure just slows us down
Note: All of the code can be found on GitHub. This article covers creating an HTML5 based drag and drop container that accepts items from compatible containers, has nice animations, and only uses React.js (no Flux based architectures). Others have written on drag and drop with React.js. It is worth the time to check out some of them. For example, Daniel at webcloud.se has a great article on creati
What is flux? Flux is an application architecture for building complex user interfaces. It eschews MVC in favor of unidirectional data flow. What this means is that data enters through a single place (your actions) and then flows outward through to their state manager (the store) and finally onto the view. The view can then restart the flow by calling other actions in response to user input. We'll
A walkthrough of the Test Driven Development (TDD) process for testing React.js components with Jest from requirements to passing tests.James Burnett I write software for fun and profit. At the moment, I'm doing front-end web development because it is fun. Test Driven Development (TDD) is a very powerful and popular development methodology. Testing React.js components is most easily accomplished w
What is Isomorphic JavaScript ? Shared JavaScript that runs on both the client & server. What's the point? JavaScript driven MVCs (angular, ember, backbone, etc.) render on DOM load, this can be really slowwwww & can make for a bad user experience. Another major problem is that they aren't indexable by search engines (without paying $$ for a third party service like https://prerender.io/). If you

The idea of "idiomatic" React hasn’t been explicitly written on, so I thought I’d offer some conventions that my team at Tune has been using during the past few months of adoption. For the sake of this article, scope will be limited to coding style in React components - not styling, componentization, or Flux strategies. Also, this is meant to be a living document - and I am sure there are better i

React is Awesome! Rails is Awesome! Jest is awesome! Using Jest with React in Rails should be Awesome Cubed... and yet it seems so difficult. Recently, the author was in a position where a legacy project wanted to redesign the front-end while keeping the Rails backend. The project decided to go with a React based redesign phased in, piecemeal, over time. Eventually the old JavaScript would just d
Facebook announced Flux at F8 in April as an application paradigm to complement React. But Flux has been pretty nebulous, as there hasn’t been much code released. The examples in Facebook’s Flux repository gave a better idea of its overall composition, but there was still a ton of boilerplate involved, and that’s usually where a library comes along to bring some level of abstraction and convenienc
Mar 28, 2017 Using Proxies with Redux Types One of the most common problems that I run into when using Redux is trying to figure out why an action is not being captured by a reducer. For someone just getting starting with Redux, debugging this issue can be especially overwhelming because of how Redux manages data flow. So before you start pouring over configuration code, or the logic contained in
