This easy-to-follow book covers all the key concepts and steps to become competent with modern versions of Vaadin. The book covers everything from setting up the development environment to implementing advanced features such as Server Push and database connectivity. The book helps you become proficient in the Vaadin framework, prepare for Vaadin certifications, and shows you how to apply the power of the Java programming language in developing applications for the web. Author Alejandro Duarte starts with an introduction to web development and its key technologies. He then describes and demonstrates how Vaadin simplifies web development by allowing you to implement web graphical user interfaces using the Java programming language without having to code in JavaScript or HTML. Once a solid foundation on the key web and Vaadin concepts is established, Duarte digs deeper into explaining layouts and user interface components such as combo boxes, dialogs, upload fields, and data grids.
