In this article we are going to do a quick introduction to Node.js and LoopBack for Ruby on Rails minded developers. What’s LoopBack? It’s an open source framework for easily developing APIs in Node and getting them connected to databases like MongoDB, MySQL, Oracle and SQL Server. We’ll cover installing Node, the StrongLoop CLI, look at an example LoopBack application plus how to start out on your own. All the while drawing parallels between Node and Rails commands.
