Before two weeks ago or so, it used to be Backbone views and models, and everything was on our main store app, and our mobile web app, but actually, we just switched our mobile web app to using ReactJS for the interface. So it’s using Backbone models but ReactJS front-end components. Really, it was borne out of the frustration with how the Backbone model-view bindings worked, and it wasn’t especially performant for large views, and we had to do lots of tricks to make it performant. But swapping that out with React views meant that it could be both simpler and faster without having to spend a lot of time on that.

One other interesting thing about that is, since React actually works okay with the Backbone models and the Backbone router and stuff like that, we didn’t have to rewrite the mobile web application and update it to ReactJS. Rewrites are almost always a bad idea. We were able to upgrade pieces of it at a time, move on to React, and now the entire thing is using React and just has the Backbone router and models and stuff like that that we already had, so it's a lot faster.

At the beginning of last year, Netflix UI engineers embarked on several ambitious projects to dramatically transform the user experience on our desktop and mobile platforms. Given a UI redesign of a scale similar to that undergone by TVs and game consoles, it was essential for us to re-evaluate our existing UI technology stack and to determine whether to explore new solutions. Do we have the right building blocks to create best-in-class single-page web applications? And what specific problems are we looking to solve? Much of our existing front-end infrastructure consists of hand-rolled components optimized for the current website and iOS application. Our decision to adopt React was influenced by a number of factors, most notably: 1) startup speed, 2) runtime performance, and 3) modularity.

React has exceeded our requirements and enabled us to build a tremendous foundation on which to innovate the Netflix experience.

Web-frontend programming prior to React: like banging rocks together. With React: Like wearing fusion powered underwear. Gives you a nice warm feeling. Using React for Cloudcraft.co allowed us to create a beautiful UI in record time (1 month start to launch), with virtually no bugs popping up during development. The functional approach to just rendering your component given a state just makes so much sense, with React figuring out the delta between your current and desired representation. It's the future kids!

AngularJS is a structural framework for dynamic web apps. With AngularJS, designers can use HTML as the template language and it allows for the extension of HTML's syntax to convey the application's components effortlessly. Angular makes much of the code you would otherwise have to write completely redundant. We can use Angular to build any kind of app, taking advantage of features like: Two-way binding, templating, RESTful api handling, modularization, AJAX handling, dependency injection, etc

React is choice number 1 when it comes to JS development at Kurzor. We choose React because it solves many issues with web applications in a elegant way. Writing an app in components is useful for coordination and isolation of concerns. React forces you to abandon state and use vertical passing through props instead. And having as many Pure Components as possible helps to write cleaner code.

With React we usually use: Redux, React Router, React Toolbox, Styled Components.

This is the best component framework and API available today for building modern web sites and apps. I really enjoy how minimal it is, and powerful at the same time. It removes opinionated development and replaces it with logic and data philosophies, which has in turn fostered a robust and lively code and support community.

All of our frontend code is on AngularJS. Directives, controllers, and services really help in organizing code in order to keep things maintainable, and two-way binding makes data input easy. The large ecosystem of modules for directives is fantastic, too.

When ever I need heavy user client side apps this is my tool of choice. There are a ton of JS frameworks out there, picked this one because of philosophy they are trying to put out there and great community. Two way data binding FTW!

The front end was built on an Angular template supplied by the client. We leveraged Angular's flexibility and speed to delivered complex matrices of data quickly and with great finesse.

We use Angular.js to build our front-end framework known as Frontkit, so our apps can get started faster with reliable, interactive components.
