umbraco-property-value-preset

Umbraco property value presets apply default values automatically by defining a propertyValuePreset manifest targeting a specific property editor alias and implementing the UmbPropertyValuePresetApi processValue method to return defaults when the incoming value is empty.

Umbraco property value presets are backoffice extensions that remove the need for users to manually enter the same default content values every time they create new items, applying defaults per chosen property editor UI alias or target schema alias.

Yes, Umbraco property value presets can return fixed defaults or compute defaults dynamically from editor configuration, including async scenarios like calling an endpoint to fetch the initial values safely and deterministically.

Multiple Umbraco property value presets are composable via weight, allowing earlier lower-weight presets to establish a base value that later higher-weight presets can refine or transform for the same targeted property editor.

Implementing Umbraco property presets requires a TypeScript propertyValuePreset manifest with the correct targeting alias or schema, alongside an UmbPropertyValuePresetApi implementation that safely returns or transforms preset values deterministically.
