WorkerExchange is an extremely lightweight wrapper for HTML5 WebWorker and SharedWorker. It provides a consistent API across both type of workers, So you won't have to replace nothing to change between the types. You can even use the same js file as both Dedicated and Shared Worker, an example of it can be found in the Demo Folder.
It automatically declares Exchange variable in Both Worker and Host scope.
It automatically creates an Exchange instance in worker scope with the name exchange.
// Host
const worker = Exchange.create('Worker.js');
// or
const worker = Exchange.createShared('Worker.js');
worker.request('some-job', {Key: 'value'}).then(function(response){
console.log(response); // Pong
});// Worker.js
importScripts('/path/to/exchange.js');
exchange.onRequest('some-job', function(data, message){
console.log(data); // {"Key": "Value"}
message.response = "Pong";
});Check out the Online Demo. (Check your browser console)
