Now we must set up the basic functions for accepting events and answering queries. We could make our own querying engine from scratch, but we can also use [eventstore](https://fiatjaf.com/nostr/eventstore). In this example we'll use the SQLite adapter:
Now we must set up the basic functions for accepting events and answering queries. We could make our own querying engine from scratch, but we can also use [eventstore](https://pkg.go.dev/fiatjaf.com/nostr/eventstore). In this example we'll use the Badger adapter:
```go
db := sqlite3.SQLite3Backend{DatabaseURL: "/tmp/khatru-sqlite-tmp"}
db := badger.BadgerBackend{Path: "/tmp/khatru-badger-tmp"}
if err := db.Init(); err != nil {
panic(err)
}
relay.UseEventstore(db)
relay.UseEventstore(db, 500)
```
These are lists of functions that will be called in order every time an `EVENT` is received, or a `REQ` query is received. You can add more than one handler there, you can have a function that reads from some other server, but just in some cases, you can do anything.
