@dumpstate/web-worker-proxy v0.1.8

web-worker-proxy

Web worker proxy for JavaScript objects.

Installation

Install package:

npm install @dumpstate/web-worker-proxy --save

Usage

1. Define and build Worker script.

import { run } from "@dumpstate/web-worker-proxy"
import { Foo } from "..."

run(async () => {
	// NB construct an object to be 'run' on the Worker.
	//    e.g. load WASM file.
	return new Foo()
})

Use your favourite build tool, to bundle the script.

2. Create worker proxy.

import { ProxyType, workerProxy } from "@dumpstate/web-worker-proxy"
import { Foo } from "..."

const foo: ProxyType<Foo> = await workerProxy<Foo>("/path/to/worker/script.js")

// NB ProxyType<Foo> is a type mapping, that for all:
//    - properties, turn them into `() => Promise<T>` functions,
//    - functions, turn them into `(...args) => Promise<ReturnType<T>>` async functions.

foo is a Proxy, that sends a message to a dedicated Worker and resolves appropriate response.
