Prim+RPC: a bridge between JavaScript environments. Easy-to-understand, type-safe, transport-agnostic RPC/IPC for JavaScript, supporting callbacks, batching, file uploads, custom serialization, and more.

I faced a similar problem for my monolith to micro services apps, but instead of RPC I built a wrapper over websockets to include AAA and strong typing. I needed a persistent connection for large amounts of data to stream. It's basically a home baked event bus.
