On Backend Development
In this course we will learn backend development with Ruby on Rails and with node.js.
There are many frameworks in different languages that could also be used. If you learn Laravel or Django or any number of other frameworks you are doing just fine.
We decided on Ruby on Rails in 2008 because the framework seemed well rounded and modern then, and we have not been disappointed. Rails has not stopped innovating and improving. In 2021 we can still recommend it both for learning and for building production ready software. In 2013 we added node.js to cover different aspects of backend development.
