bloomHydratedAttribute top-level constant

String const bloomHydratedAttribute

DOM attribute name added to an island placeholder element once hydration is complete.

Prevents redundant hydration passes and indicates active client-side reactivity.

// Set to 'true' upon successful hydration:
// <div data-bloom-island="menu" data-bloom-hydrated="true">...</div>

Implementation

const String bloomHydratedAttribute = 'data-bloom-hydrated';
