List of JS / MVC/ Realtime / Event driven frameworks

Just documenting a list of contenders for upcoming app project

React

Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
React uses a virtual DOM diff implementation for ultra-high performance. It can also render on the server using Node.js — no heavy browser DOM required.
React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.

Flight is a lightweight, component-based JavaScript framework that maps behavior to DOM nodes. Twitter uses it for their web applications. By way of example, we've included a simple email client demo (browse the source) built over the Flight framework. There's also a flight implementation over on the todoMVC site (source), courtesy of @mkuklis
Flight uses ES5-shim and jQuery. Additionally you will need to include an AMD implementation such as require.js or loadrunner. Please read the Flight documentation for installation instructions.

We want to enable you to build complete web apps in days, without having to worry about backends, databases or servers, all with an open source library that's as simple to use as jQuery.
Hoodie is an Offline First and noBackend architecture for frontend-only web apps on the web and on iOS.

With one command, your API is up and running. It's an empty canvas waiting for you to add Resources. No boilerplate code necessary.
