@exodus/await-proxy

Proxies a module and delays all module calls until the specified promise resolves.

Usage

This is an example of desktop RPC usage:

import awaitProxy from '@exodus/await-proxy'
import { createClient } from '#/electron-rpc-broadcast'
import Handshake from '#/handshake'

const handshake = new Handshake({
  sendMessage: (message) => ipc.targeted('core', 'handshake', message),
  attachListener: (listener) => ipc.on('handshake', listener),
})

// calls to some-module will be queued until the RPC server is initialized (as indicated by the handshake)
export default awaitProxy({
  object: createClient('core', 'some-module'),
  delayUntil: handshake.awaitDone(),
})

API

awaitProxy({ object, delayUntil, synchronousMethods })

• object is the module to be proxied (should only have functions/methods; no properties)
• delayUntil is the Promise to await before calling methods on object
• synchronousMethods is an optional array of strings, denoting methods names on object that are synchronous, but return an object with async methods. Calls to synchronous methods will return a Proxy, with async functions that await promise before actually executing. The underlying synchronous method will only be called after promise resolves. s
