triolet.worker

DRIVER in the main thread; API and DSP in the worker thread. This architecture works on the browser.

Installation

$ npm install triolet.worker

Example

in the main thread

const triolet = require("triolet.worker/client")();
const Driver = require("pico.driver.webaudio");

let audioContext = new AudioContext();

triolet.compose({ workerPath: "/path/to/worker", driver: new Driver() });
triolet.setup({ context: audioContext, bufferLength: 1024 });

triolet.sendToWorker({ type: "start" });

in the worker thread

const triolet = require("triolet.worker/worker")(self);
const API = require("./api");
const DSP = require("./dsp");

triolet.compose({ api: new API(), dsp: new DSP() });

triolet.recvFromClient = (e) => {
  if (e.type === "start") {
    triolet.start();
  }
};
