Thymeleaf
Thymeleaf is a modern server-side Java template engine for web and standalone environments. It processes HTML, XML, JavaScript, CSS, and text files, allowing developers to create natural templates that can be displayed correctly in browsers and also work as static prototypes. It integrates seamlessly with Spring Framework, making it a popular choice for building dynamic web applications in Java.
Developers should learn Thymeleaf when building server-side rendered web applications with Java, especially in Spring-based projects, as it provides a clean separation of concerns and supports natural templating. It is ideal for use cases like generating dynamic HTML content, email templates, or reports where server-side processing is required, and it avoids the need for complex JavaScript frameworks for simple dynamic pages.
