Seaside - Building Complex Web Applications Simply

par Lukas Renggli netstyle.ch GmbH

salle 259 à 16h30

Résumé

It would be hard to imagine a worse model for user interface development than HTTP. Would you use a GUI framework where every event from every widget in your application was handed to you at once, periodically, as a large hashtable full of strings? Where every time a single piece of data changed you had to regenerate a textual description of the entire interface? Where the event-based architecture was so strict that you couldn't ever, under any circumstances, open a modal dialog box and wait for it to return an answer? Those are the costs of using the web browser as a client platform, and, by and large, we accept them. The dominant paradigms of web development -- CGI, Servlets, Server Pages -- do very little to hide or circumvent the low level realities of HTTP, and as a result, web applications are fragile, verbose, and ill-suited to reuse.

Seaside (http://beta4.com/seaside2) solves these problems. Seaside is a framework for developing sophisticated web applications. In this talk I will present some of its unique features, such as its approach to session management: unlike servlet models that require a separate handler for each page or request, Seaside models an entire user session as a continuous piece of code, with natural, linear control flow. Furthermore I will create a small web-application as a demo together with the audience and present a complex production web-site that has been built using Seaside.

Lukas Renggli (netstyle.ch) is specialist in the development of web applications and content management systems. He is expert in Zope, PHP and web solutions, the designer of SmallWiki, a content management application entirely based on objects. Lukas Renggli is working for netstyle.ch, where he is currently building web-applications in the business domain for insurances and print-shops. Lukas Renggli has given talks about Seaside at ESUG 2002, ESUG 2003 and for CHOOSE.
