Typed pub/sub
Define a publication, subscribe over a live socket, and a reactive store fills from MongoDB change streams.
Fastify, MongoDB and WebSocket with a typed pub/sub protocol. Built test first with James Shore's Nullables pattern, no mocks anywhere in the suite.
EkoLite is public and a work in progress, published early at 0.x to claim the name and share the shape. The public API is still settling and can change between 0.x releases, so pin a version and read the release notes before upgrading. Not recommended for production yet.
