Scalatra in Action

Summary

Scalatra in Actionintroduces the Scalatra framework and the Sinatra model. It covers the framework in its entirety, starting with concepts like request routing, input handling, actions, and HTTP responses, then proceeds to more advanced topics, such as data access, handling heavy load, asynchronicity, securing applications, designing and documenting RESTful APIs, and real-time web programming.

Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.

About the Technology

Scalatra is a lightweight Scala web framework similar to the popular Ruby-based Sinatra. It’s perfect for running real-time applications on multicore servers, and is a fast way to spin up web apps and build HTTP APIs for mobile, Backbone.js, and AngularJS apps.

About the Book

Scalatra in Actioncovers the Scalatra framework in its entirety, starting with concepts such as request routing, input handling, actions, and HTTP responses.
