refspace

A ref is a reference to a value. A value is either a primitive, a function or an object. An object has values and methods. A refspace holds values with attached ref objects. A refspace can be connected to another refspace, which allows the other to call methods on object refs. The transport bus is pluggable. Included is a local bus and a bus that works over any binary stream. A bus to work over window.postMessage is in the works.

When calling methods, you can pass arguments and return values as you would on local objects. All methods have to be asynchronous (return a promise). You may only use as arguments:

• primitives
• functions (they can be invoked from an remote end)
• plain json objects
• other refs
• streams
• array buffers

const value = {
  id: 'db-1',
  query: (question) => 'Dont know about ' + question.toUpperString()
}
 
const worker = refspace()
const ui = refspace()
 
const workerT = streambus()
const uiT = streambus()
 
// these are all binary streams.
pump(workerT.stream, uiT.stream)
pump(uiT.stream, workerT.stream)
 
const workerRef = worker.ref(value)
const screenRef = screen.proxy(workerRef)
 
worker.addPeer(screen.id, workerT)
screen.addPeer(worker.id, screenT)
 
const res = await screenRef.query('gossip')
console.log(res)
