Background Workers

Taking some complexity away from web workers API while enhanced them a bit

Features and overview

• creates a worke on the fly without the need of a dedicated file unsing InlineWorker class

const worker = new InlineWorker(data => {
   function factorial(n) {
       if (n === 0 || n === 1)
           return 1

       return n * factorial(n - 1)
   }

   postMessage(factorial(data))
});

worker.start(123, result => console.log("result: " + result))

...or by giving them their file

 const worker = new BackgroundWorker('./my-worker.js', 'pippo')

• checks if a worker is active or not

if (worker.isActive) {
  // Worker is running you can send and recive messages
}

• get last value posted by the worker

const value = worker.lastValue

• easily extendable using WebWorker class
• checks if worker are currently supported by the browser in use
• automatically terminate worker and log error in console if something went wrong
