The gap between front-end and back-end in web development has widened in recent years. In front-end programming, frameworks such as Angular, React, or Vue.js are predominant, forcing developers to use a different programming language and ecosystem. This has made it more difficult for Java developers to keep up with front-end development, and in many projects, front-end and back-end developers are separated.

However, it can be beneficial if a developer can develop both the front-end and back-end. But as a Java developer, do I have to get familiar with a whole new ecosystem? 
No, there are alternatives!

This deep dive shows how to develop web applications efficiently as a Java full-stack developer. We will compare three options that suit the Java developer: Vaadin, Quarkus Qute with HTMX, and Jakarta Faces (JSF). We will examine the advantages and disadvantages based on an example to determine which framework is the best choice in each scenario.
