What are the best options for building JSON RPC client/server in javascript ? Essentially I am looking at a Node.js based server and Browser based client as of now but cross language compatibility would be nice to have. gRPC pure javascript client [3] is labelled as "incomplete and experimental". axon [4] looks interesting but seems to have received no activity in almost a year. I am also slightly skeptical of adopting a tj project given his departure from Node community. Jayson [1] was the only one I could find in the search results [2] which is actively maintained and well documented. -- [1] https://github.com/tedeh/jayson https://github.com/tedeh/jayson [2] https://npms.io/search?q=rpc https://npms.io/search?q=rpc [3] https://github.com/grpc/grpc-node#pure-javascript-client https://github.com/grpc/grpc-node#pure-javascript-client [4] https://github.com/tj/axon https://github.com/tj/axon
