xxxProcessor.js

class XxxProcessor extends AudioWorkletProcessor {
  constructor(...args) {
    super(...args);
    this.port.onmessage = (e) => {
      console.log(e.data);
      this.port.postMessage("pong");
    };
  }
  process(inputs, outputs, parameters) {
    return true;
  }
}

registerProcessor("xxx-processor", XxxProcessor);

const audioContext = new AudioContext();
await audioContext.audioWorklet.addModule('xxxProcessor.js');
const audioWorkletNode = new AudioWorkletNode(audioContext, 'xxx-processor', options);
audioContext.context(audioWorkletNode).context(audioContext.destination);

audioWorkletNode.port.onmessage = (e) => console.log(e.data);
