How to use the replay.localhost function in replay

const Browser = require('../../src');
const debug   = require('debug')('server');
const Express = require('express');
const morgan  = require('morgan');
const Replay  = require('replay');


// Need sparate port from the test server (see index.js).
const PORT      = 3005;
const HOSTNAME  = 'thirdparty.test';


// This will map any HTTP request to theweb.test to the right port.
Browser.localhost(HOSTNAME, PORT);
Replay.localhost(HOSTNAME);


const server = new Express();

// Even tests need good logs
if (debug.enabled)
  server.use(morgan('dev', { stream: { write: debug } }));

// ... and error reporting
server.use(function(error, req, res, next) {
  console.error(error);
  next(error);
});


// Promise that resolves to a running server.

// We switch this directory to instrumented code when running code coverage
// report
const Replay    = require('replay');
const Browser   = require('../../src');


Browser.default.silent = true;
// Tests visit example.com, server is localhost port 3003
Browser.localhost('*.example.com', 3003);


// Redirect all HTTP requests to localhost
Replay.fixtures = __dirname + '/../replay';
Replay.networkAccess = true;
Replay.localhost('*.example.com');


module.exports = {
  assert:   require('assert'),
  brains:   require('./brains'),
  Browser:  Browser
};

const Bluebird  = require('bluebird');
const Browser   = require('../../src');
const Path      = require('path');
const Replay    = require('replay');


// Tests visit example.com, server is localhost port 3003
Browser.localhost('*.example.com', 3003);

// Redirect all HTTP requests to localhost
Replay.fixtures = Path.join(__dirname, '/../replay');
Replay.networkAccess = true;
Replay.localhost('*.example.com');

// Long stack traces when running this test suite
Bluebird.longStackTraces();
