Implement web applications in Java using the open-source Vaadin framework version 20 and later. 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. He also covers topics such as styling with CSS, data binding, client-side views implementation with TypeScript, and integration with Spring Boot and Jakarta EE. You will learn to:

• Build web applications in Java using Servlet technology and Vaadin
• Combine layouts and user interface components to create views in Java
• Connect values in UI components to Java objects in the server through data binding
• Customize display styles and add responsive capabilities using CSS
• Display tabular data using the Grid component
• Implement client-side views using TypeScript
• Integrate Vaadin applications with Spring Boot and Jakarta EE

• Connect Vaadin applications to SQL databases

Alejandro started to code at age 13 using the BASIC programming language on a black screen with a blinking cursor serving as the IDE. He quickly moved to the C and C++ languageswhich he still loves and enjoysand then to Java during his Computer Science studies at the National University of Colombia from where he graduated. Alejandro moved to the UK and later to Finland to foster his career in the open-source software industry. He became one of the well-known faces in the Vaadin and Java communities, having published articles and videos with hundreds of thousands of views in official Vaadin channels and other content portals, and presented technical topics at international Java conferences and Java User Groups.
