Package: effect
Module: RequestResolver

RequestResolver.persisted

Wraps a request resolver with persistent storage for persistable requests.

When to use

Use to keep a RequestResolver interface while reusing completed Persistable request results through a Persistence store.

Details

Cached results are loaded from the configured persistence store before running the underlying resolver. Missing entries are resolved normally and written back to the store. Entries marked stale by staleWhileRevalidate receive the stored result and are also resolved again so the refreshed result can be written back to the store. Creating the persisted resolver requires Persistence.Persistence and Scope.

See

• withCache for in-memory resolver caching that does not require persistable request values or a persistence store
• asCache for exposing resolver results through a Cache instead of returning another resolver

Signature

declare const persisted: { <A extends Request.Request<any, Persistence.PersistenceError | Schema.SchemaError, any> & Persistable.Any>(options: { readonly storeId: string; readonly timeToLive?: ((exit: Request.Result<A>, request: A) => Duration.Input) | undefined; readonly staleWhileRevalidate?: ((exit: Request.Result<A>, request: A) => boolean) | undefined; }): (self: RequestResolver<A>) => Effect.Effect<RequestResolver<A>, never, Persistence.Persistence | Scope>; <A extends Request.Request<any, Persistence.PersistenceError | Schema.SchemaError, any> & Persistable.Any>(self: RequestResolver<A>, options: { readonly storeId: string; readonly timeToLive?: ((exit: Request.Result<A>, request: A) => Duration.Input) | undefined; readonly staleWhileRevalidate?: ((exit: Request.Result<A>, request: A) => boolean) | undefined; }): Effect.Effect<RequestResolver<A>, never, Persistence.Persistence | Scope>; }
