Interface OutboxStore

Pluggable persistence for the offline send queue (the outboxStore option). Both methods receive the storage key (pouchy-outbox:${surface}, or pouchy-outbox-v:${surface}:${visitorId} on a representative session); load returns the previously-saved value or null.

interface OutboxStore {
load(key: string): string | null;
save(key: string, value: string): void;
}
