injectorFn?	InjectorFn	Optional function to resolve DI tokens (required for dbToken strategy)

Returns

Promise<Db>

The resolved MongoDB Db instance

Throws

Error if no database strategy is provided or if DI resolution fails

Example

// Direct Db instance
const db = await resolveDatabase({ db: mongoDb });

// Factory function
const db = await resolveDatabase({
  dbFactory: async () => {
    const client = await MongoClient.connect(uri);
    return client.db("myapp");
  }
});

// DI token
const db = await resolveDatabase(
  { dbToken: "MONGODB_DATABASE" },
  (token) => injector.get(token)
);
