Workhole module

Creates a bridge between main context and worker context for easier interaction.

Importing an object from another context allows access to methods of that object that will be called in its native context with arguments passed to that context and result being returned back as a promise.

Module is symmetrical with same file and methods used in both contexts.

Usage

Create a workhole

Main context:

import Workhole from "workhole.js"

const worker = new Worker("worker.js", {
    type : "module"
})
const workhole = new Workhole(worker)

Worker context:

import Workhole from "workhole.js"

const workhole = new Workhole(self)

Share an object

"Exporting" context:

const summator = {
    sum (a, b) {
       return a + b 
    }
}

workhole.export(summator, "summator")

"Importing" context:

//does not care if object was actually exported
const summator = workhole.import("summator")

//checks if object was actually exported, waits for it otherwise
const summator = await workhole.expectExport("summator")

Note the actual object is not transferred, but a handle for it is created instead on "importing" side.

Call methods of shared object

In "importing" context:

console.log(await summator.sum(1, 2)) //3
