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();
