API

Worker(script)

Initialize a worker with the given script.

Worker#send(msg)

Send a message to the worker.

var upper = new Worker('uppercase.js');

upper.on('message', function(msg){
  console.log(msg.string);
});

upper.send({ string: 'hello' });
upper.send({ string: 'world' });

Worker#send(msg, callback[, transferables])

Send a request message to the worker with the given callback. When using the request/response paradigm you should pass the e.data.id property back with your response so that the correct callback may be invoked:

worker:

onmessage = function(e) {
  setTimeout(function(){
    postMessage({ id: e.data.id, string: e.data.string.toUpperCase() });
  }, 500);
};

client:

upper.send({ string: 'hello' }, function(msg){
  console.log(msg.string);
});

Worker#close()

Terminate the worker.
