ApiPublisher

ApiPublisher is a Node.js framework for exposing asynchronous JavaScript APIs (returning Promises) over HTTP, enabling identical async function calls on client and server. Current version 2.1.5 requires Node >=10.0.0. It ships TypeScript types. Key differentiators: works seamlessly with Connect/Express, supports ES7 async/await via Nodent, offers browser RemoteApi with caching (including localStorage), and has been in production since 2013. Unlike generic RPC libraries, it preserves Promise semantics and supports nested APIs automatically.
