Questions tagged [spark-framework]

Spark Framework - A tiny Java web framework. Use this tag for Spark framework related questions. Spark is a free and open-source software web application framework and domain-specific language written in Java. This is not for Apache Spark, this is for a web application framework.

Spark Framework is a simple and lightweight Java web framework built for rapid development built in Java.

It is an alternative to other Java web application frameworks such as JAX-RS, Play framework and Spring MVC. It runs on an embedded Jetty web server by default, but can be configured to run on other webservers.

Spark was originally inspired by the web framework Sinatra, but it's intention isn't to compete with Sinatra, or other similar web frameworks in different languages.
