defineMaterializer

const defineMaterializer: <TEventDef>(_eventDef, materializer) => Materializer<TEventDef>

Defined in: packages/@livestore/common/dist/schema/EventDef/materializer.d.ts:111

Useful when defining materializers separately from the materializers() builder. The first argument provides type inference for the second.

const todoCreatedHandler = defineMaterializer(
  events.todoCreated,
  ({ id, text }) => tables.todos.insert({ id, text, completed: false })
)
