A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources and web APIs. Web frameworks aim to alleviate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks and session management, and they often promote code reuse. Though they often target development of dynamic websites they are also applicable to static websites.
