cache management for angular services

When managing cached data in services we face many issues caused by the fact that we work with two different databases (the real database in back, the cached data in front). since cache in some services are refreshed independently (more/less frequently) than others. This creates data incoherence like a component that uses a service that has a more updated data than another.

Is theire any design patterns that would guide us to handle cache in angular services whithout data incoherence ?
