Use talkback as a wiremock/api proxy for consistent API testing, in a Worker thread! (NodeJS)

module1.test.js

import { Worker } from 'worker_threads';

import MyClient from './my-client.js';

const proxyAPI = new Worker(__dirname + "/server-worker.js");

define('Module1', () => {
  let client;
  beforeEach(() => {
  	client = new MyClient("http://localhost:5544");
  });
  after(() => {
  	proxyAPI.terminate();
  });

  it('should contact the proxyAPI in the client', () => {
  	// client.get('foo') etc
  });
});

server-worker.js

import { isMainThread } from 'worker_threads';
// import talkback from "talkback/es6";

if (!isMainThread) {
  const talkback = require("talkback");

  const opts = {
    host: "https://api.myapp.com/foo",
    port: 5544, // be sure to reference http://localhost:5544 in your client!
    record: talkback.Options.RecordMode.NEW,
    path: __dirname + "/my-api-response-tapes",
    silent: true
  };
  const server = talkback(opts);
  server.start(() => console.log("Talkback Started"));
}
