Nested Worker polyfill for Safari. Uses MessageChannel to avoid having to send all messages through the main thread. Does not support Shared Workers.

Install

yarn add git+https://github.com/johanholmerin/nested-worker#semver:^1.0.0

Usage

Import the polyfill in the main thread before creating any worker, and as the first statement in all workers.

// in window
import 'nested-worker/window.js';
const worker = new Worker('worker.js', {
  type: 'module' // or transpile modules
});

// worker.js
import 'nested-worker/worker.js';
const nestedWorker = new Worker('another-worker.js', {
  type: 'module' // or transpile modules
});

// another-worker.js
import 'nested-worker/worker.js';
