Redux is a predictable state container for JavaScript apps.

It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test. On top of that, it provides a great developer experience, such as live code editing combined with a time traveling debugger.

You can use Redux together with React, or with any other view library.

Horizon consists of three components:

Horizon server: a middleware server that connects to/is built on top of RethinkDB, and exposes a simple API/protocol to front-end applications.
Horizon client: a JavaScript client library that wraps Horizon server’s protocol in a convenient API for front-end developers.
Horizon CLI: a command line tool, hz, aiding in scaffolding, development, and deployment.
