Server-side web programming in WASH

Abstract

WASH makes server-side Web programming as easy as programming a stand-alone application with an XHTML-based GUI. Starting from an interaction graph model of the application where nodes model web pages and edges correspond to form submissions, each node is implemented by a WASH function and the edges correspond to function invocation. Nodes can be decomposed further into "pagelets", which are XHTML fragments bundled with associated logic. We give an introduction to the concepts of WASH programming with this methodology and advocate the design of interactive web functionality in terms of such pagelets. The two components of a pagelet may be specified monolithically or in separation. Pagelets may also be composed up to an entire WASH page. The development of a web-based logging application serves as a running example. © Springer-Verlag Berlin Heidelberg 2005.
