I recently published this library for routing messages within an application using the same kind of wildcard semantics that NATS uses - https://www.npmjs.com/package/@gooseus/natsrun https://www.npmjs.com/package/@gooseus/natsrun Currently just test driving it in some relatively simple work scenarios, but I imagine it could be a useful tool for consuming a NATS firehose of messages in a single application and routing them internally using the same semantics subject rules so that it would be easy to split them out as separate consumers when/if that became necessary.
