JavaFX WebView loads HTML with JavaScript binding a Java object. Include this in the class diagram? Example:
JSObject jsRef = (JSObject) engine.exec("window"); jsRef.setMember("bridge", new DataObject());
Based on my experience, HTML and JavaScript elements are best considered implementation details rather than classes themselves. A class diagram is most useful when illustrating the structure of the core system by focusing solely on key business objects and their relationships. External components, such as a WebView or JavaScript interface, should be documented separately as part of the system’s deployment or integration notes. This approach helps to maintain the diagram’s clarity and ensures it remains focused on the system’s fundamental architecture.
Based on my own experience working on web-based Java applications, I’ve noticed that including HTML and JavaScript elements in class diagrams can detract from the clarity of the domain model. Class diagrams are most effective when they represent the core system abstractions rather than the user interface components or integration layers. In my projects, I’ve kept such elements in separate documentation or integration diagrams, ensuring the main class diagram remains focused on the business logic and relationships. This strategy helps in managing diagram complexity while still accounting for the connections to external web technologies.
