Datomic is bundled with a REST server: http://docs.datomic.com/rest.html http://docs.datomic.com/rest.html. And it includes an endpoint to subscribe to a stream of Server-Sent Events, which lets you drink from the transaction-report firehose. But there is a lot of data in that stream. I'm writing a production Pedestal app, and I could definitely use the capability to store my data on the client in the same shape as Datomic and query it with Datalog.
