# Interface: TypedStateService

Defined in: [registry.ts:414](https://github.com/simshanith/lit-ui-router/blob/740888c2b2ba358c4dfa52a122e927df6a604b12/packages/ui-router-registry/src/registry.ts#L414)

A typed view of core's `StateService`. It is assignable both ways: core's
class fills a typed getter or field with no cast and emits nothing, and the
view passes wherever a `StateService` is expected.

## Extends

* [`StateService`](https://ui-router.github.io/core/docs/latest/classes/_state_stateservice_.stateservice.html)
