Writing a Thymeleaf component library - part 2
Part 2 of a series on building a Thymeleaf component library for Spring Boot. Covers creating a custom Thymeleaf dialect with a prefix (tcl:) so components can be used as custom tags like <tcl:button> instead of verbose th:replace fragments. Walks through implementing a ComponentElementProcessor that maps custom tags to fragment templates, building a button component with CSS, enabling live reload of HTML templates via FileTemplateResolver and Vite, and handling arbitrary element attributes via a custom AttrsExceptAttributeProcessor that passes through unhandled attributes (like hx-* for htmx) while merging the class attribute and excluding explicitly handled props like 'primary'.
