AttributeMode type

The mode that specifies the runtime behavior of the attribute.

export declare type AttributeMode = "reflect" | "boolean" | "fromView";


By default, attributes run in reflect mode, propagating their property values to the DOM and DOM values to the property. The boolean mode also reflects values, but uses the HTML standard boolean attribute behavior, interpreting the presence of the attribute as true and the absence as false. The fromView behavior only updates the property value based on changes in the DOM, but does not reflect property changes back.
