💖 Using Webpack? You want workerize-loader ➡️

Workerize

Moves a module into a Web Worker, automatically reflecting exported functions as asynchronous proxies.

• Bundles a tiny, purpose-built RPC implementation into your app
• If exported module methods are already async, signature is unchanged
• Supports synchronous and asynchronous worker functions
• Works beautifully with async/await
• Just 800 bytes of gzipped ES3

Install

npm install --save workerize

Usage

Pass either a function or a string containing code.

worker.js:

let worker = workerize(`
    export function add(a, b) {
        // block for half a second to demonstrate asynchronicity
        let start = Date.now();
        while (Date.now()-start < 500);
        return a + b;
    }
`);

(async () => {
    console.log('3 + 9 = ', await worker.add(3, 9));
    console.log('1 + 2 = ', await worker.add(1, 2));
})();
