Comlink Loader Versions Save

comlink-loader version 2 changes the behavior of the singleton option, making it simpler than before and allowing TypeScript types work without any casting.

Now, importing a module using the comlink-loader?singleton! prefix immediately runs the module in a Web Worker and returns/reflects the module's exports:

export async function reverse (str) {
  return str.split('').reverse().join('');
}

import { reverse } from
  'comlink-loader?singleton!./worker';

await reverse('foo')  // "oof"

Note: seamless TypeScript support requires comlink-loader to be configured to apply to .worker.ts files in your Webpack configuration.

• Filter options to avoid a worker-loader error when using ?singleton (thanks @jackyef!)
• Fix support for Windows paths (thanks @nicolasmartinezv!)

• Add new ?multi option to allow multiple instances of the worker:

import Foo from 'comlink-loader?multi!./foo.worker';

await new Foo()  // creates a new worker
await new Foo()  // creates another new worker

Initial release!
