Installing Derby JS on Ubuntu Jun 11, 2013 Derby is one of a new breed of JavaScript frameworks that take advantage of the interesting NodeJS to create a web app framework that runs your code both on the client and the server. This has a tonne of huge advantages compared to writing a complex JavaScript application that has to communicate with a different language on the server and still maintain visibility to Google. The big advantages I see from this: Only one language to work in makes it easier for developers Communcation between client and server is automatic and seemless Pre-rendered on the server, updated on the client so Google gets the proper content but you still get dynamic updating for your users So with this in mind I decided to do a little test app and of course the first step was getting it installed. These are the steps I had to go through to get it working.
