Modern frontends with htmx

Use htmx with Spring Boot and Thymeleaf to build dynamic and interactive web application

About the Book

Imagine creating dynamic, interactive web applications with minimal JavaScript. That’s the revolutionary promise of htmx, a technology that redefines frontend development. This book is your gateway to mastering htmx alongside Java, Spring Boot, and Thymeleaf, transforming the way you build web interfaces.

This book starts with the basic steps of using htmx, starting from the basic techniques of DOM element swapping through various triggers. It progressively delves into more complex topics, such as responding to htmx requests in the Spring Boot controller and implementing comprehensive UI patterns like lazy loading, active search, and endless scrolling. Further, the book dives into the integration of web components and JavaScript frameworks with htmx to amplify client-side interactivity.

Throughout the book, two projects put all these ideas together. These projects help you see how everything you've learned works in real web applications.
