Vaadin CKEditor 5 component.

Modular CKEditor 5 integration with plugin-based customization.

Usage examples:

 // Use preset
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPreset(CKEditorPreset.STANDARD)
     .build();

 // Custom plugins (dependencies auto-resolved)
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPlugins(CKEditorPlugin.BOLD, CKEditorPlugin.ITALIC, CKEditorPlugin.IMAGE_CAPTION)
     .withToolbar("bold", "italic", "|", "insertImage")
     .build();
 // IMAGE_CAPTION automatically includes IMAGE plugin as dependency

 // Customize preset
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPreset(CKEditorPreset.BASIC)
     .addPlugin(CKEditorPlugin.TABLE)
     .withLanguage("zh-cn")
     .build();

Dependency Resolution:

The builder automatically resolves plugin dependencies by default. For example, adding IMAGE_CAPTION will automatically include the IMAGE plugin.

 // Auto-resolve with recommended plugins for full feature set
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPlugins(CKEditorPlugin.IMAGE)
     .withDependencyMode(DependencyMode.AUTO_RESOLVE_WITH_RECOMMENDED)
     .build();
 // Includes IMAGE plus recommended: IMAGE_TOOLBAR, IMAGE_CAPTION, IMAGE_STYLE, IMAGE_RESIZE

 // Strict mode - fail if dependencies missing
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPlugins(CKEditorPlugin.IMAGE_CAPTION) // Missing IMAGE dependency
     .withDependencyMode(DependencyMode.STRICT)
     .build(); // Throws IllegalStateException

 // Manual mode - no dependency checking
 VaadinCKEditor editor = VaadinCKEditor.create()
     .withPlugins(CKEditorPlugin.ESSENTIALS, CKEditorPlugin.PARAGRAPH, CKEditorPlugin.BOLD)
     .withDependencyMode(DependencyMode.MANUAL)
     .build();
