It is a Hobby-RPC client for browsers and Node.js, using the built-in Fetch API. To install:

npm i hobby-rpc

A usage example:

import { RPC } from 'hobby-rpc'

rpc = RPC
  url: 'https://some.domain'
  token: 'authorization token'

output = await rpc 'SomeNullaryFunction'
output = await rpc 'SomeUnaryFunction', input

input can be any object serializable to JSON. It will be passed to the remote function as an argument.

The remote server at https://some.domain is expected to implement SomeNullaryFunction and SomeUnaryFunction.

output would be an object deserialized from JSON.

This client works only via TCP sockets. Other client works via Unix sockets too.
