Variable: reactive

const reactive: (value, context) => void

Defined in: flow/src/decorators.ts:607

Marks a child-component prop as reactive — the parent re-pushes new values into it on every re-render.

Parameters

value

unknown

context

ClassFieldDecoratorContext

Returns

void

Remarks

The prop is included in the snapshot and is client-writable (so the framework can deliver the parent's updates), and the parent re-emits it so the child re-renders when the bound value changes. This is a one-way parent→child binding; use @modelable for two-way. Mirrors Livewire's #[Reactive]. Applies to a field only.

Example

class PriceTag extends Component {
  // Re-pushed by the parent whenever the parent's bound value changes.
  @reactive amount = 0;
}
