A collection of reusable database connectors, wrappers and schemas that store Nostr events and expose a simple Go interface:
type Store interface {
// Init is called at the very beginning by [Server.Start], after [Relay.Init],
// allowing a storage to initialize its internal resources.
Init() error
// Close must be called after you're done using the store, to free up resources and so on.
Close()
// QueryEvents is invoked upon a client's REQ as described in NIP-01.
// it should return a channel with the events as they're recovered from a database.
// the channel should be closed after the events are all delivered.
QueryEvents(context.Context, nostr.Fil
5A41
ter) (chan *nostr.Event, error)
// DeleteEvent is used to handle deletion events, as per NIP-09.
DeleteEvent(context.Context, *nostr.Event) error
// SaveEvent is called once Relay.AcceptEvent reports true.
SaveEvent(context.Context, *nostr.Event) error
}
There is an eventstore command-line tool that can be used to query these databases directly.
