Classes

ClassDescription
AttachedBehaviorDirectiveA directive that attaches special behavior to an element via a custom attribute.
AttributeDefinitionAn implementation of Accessor that supports reactivity, change callbacks, attribute reflection, and type conversion for custom elements.
BindingBehaviorA behavior that updates content and attributes based on a configured BindingDirective.
BindingDirectiveA directive that configures data binding to element content and attributes.
ChildrenBehaviorThe runtime behavior for child node observation.
ControllerControls the lifecycle and rendering of a FASTElement.
DirectiveInstructs the template engine to apply behavior to a node.
ElementStylesRepresents styles that can be applied to a custom element.
ExecutionContextProvides additional contextual information available to behaviors and expressions.
FASTElementDefinitionDefines metadata for a FASTElement.
HTMLViewThe standard View implementation, which also implements ElementView and SyntheticView.
PropertyChangeNotifierAn implementation of Notifier that allows subscribers to be notified of individual property changes on an object.
RefBehaviorThe runtime behavior for template references.
RepeatBehaviorA behavior that renders a template for each item in an array.
RepeatDirectiveA directive that configures list rendering.
SlottedBehaviorThe runtime behavior for slotted node observation.
SubscriberSetAn implementation of Notifier that efficiently keeps track of subscribers interested in a specific change notification on an observable source.
ViewTemplateA template capable of creating HTMLView instances or rendering directly to DOM.

Functions

FunctionDescription
attr(config)Decorator: Specifies an HTML attribute.
attr(target, prop)Decorator: Specifies an HTML attribute.
children(propertyOrOptions)A directive that observes the childNodes of an element and updates a property whenever they change.
compileTemplate(template, directives)Compiles a template and associated directives into a raw compilation result which include a cloneable DocumentFragment and factories capable of attaching runtime behavior to nodes within the fragment.
css(strings, values)Transforms a template literal string into styles.
customElement(nameOrDef)Decorator: Defines a platform custom element based on FASTElement.
elements(selector)Creates a function that can be used to filter a Node array, selecting only elements.
html(strings, values)Transforms a template literal string into a renderable ViewTemplate.
observable(target, nameOrAccessor)Decorator: Defines an observable property on the target.
ref(propertyName)A directive that observes the updates a property with a reference to the element.
repeat(itemsBinding, templateOrTemplateBinding, options)A directive that enables list rendering.
slotted(propertyOrOptions)A directive that observes the assignedNodes() of a slot and updates a property whenever they change.
volatile(target, name, descriptor)Decorator: Marks a property getter as having volatile observable dependencies.
when(binding, templateOrTemplateBinding)A directive that enables basic conditional rendering in a template.
