Scalatra's philosophy

1. Start small, build upwards

Start with a small core, and have lots of easy integrations for common tasks.

2. Freedom

Allow the user freedom to choose whatever structure and libraries make the most sense for the application being built.

3. Solid, but not stolid

Use solid base components. For instance, servlets aren’t cool, but they are extremely stable and have a huge community behind them. At the same time, work to advance the state of web application development by using new techniques and approaches.

4. Love HTTP

Embrace HTTP and its stateless nature. People get into trouble when they fool themselves into thinking things which aren’t true - fancy server-side tricks to give an illusion of statefulness aren’t for us.
