Dozens of toolkits offer a wide range of widgets to build rich web applications on top of HTML5 platform. For a real world application the included widgetset is rarely enough and development of custom user interface components is required. Design of a reusable component is far from trivial.
In this presentation Joonas Lehtinen, one of the authors of the popular Vaadin Framework shows how a new component can be designed and implemented from scratch. Topics covered include considerations for choosing DOM structure, finding a balance between performance and features, implementation considerations and testing the component. During the presentation a new component is implemented from scratch with Google Web Toolkit and packaged as a Vaadin Framework add-on ready for use by third parties.
Joonas Lehtinen, PhD, is one of the core developers of Vaadin, a Java-based framework for building business-oriented Rich Internet Applications. Joonas has been developing applications for the web since 1995 with a strong focus on Ajax and Java. He is the founder and CEO of the company behind the Vaadin framework.
