Error: connect ECONNREFUSED 127.0.0.1:9222

Config / CLI options

pwmetrics https://example.com is not working on a fresh yarn global install.

Steps to reproduce.

yarn global add pwmetrics
pwmetrics https://example.com

Debugging info

1. Using lighthouse

yarn global add lighthouse
lighthouse https://example.com

This command works fine and Chrome is launched.

2. Using chrome-launcher

const ChromeLauncher = require('chrome-launcher');

ChromeLauncher.launch({
  port: 9222,
  startingUrl: 'http://localhost:9000/us/en-us/suv-rental',
}).then(chrome => {
  console.log(`Chrome debugging port running on ${chrome.port}`);
});

Chrome is launched.

3. Calling lighthouse programmatically works

const ChromeLauncher = require('chrome-launcher');
const lighthouse = require('lighthouse');

ChromeLauncher.launch({
  startingUrl: 'https://example.com',
}).then(chrome => {
  console.log(`Chrome debugging port running on ${chrome.port}`);
  return lighthouse('https://example.com', {port: chrome.port}).then(results => {
    return chrome.kill().then(() => console.log(results.lhr));
  });
});

This prints the audit output to console.

4. Manual programmatic override

const ChromeLauncher = require('chrome-launcher');
const PWMetrics = require('pwmetrics');

ChromeLauncher.launch({
  startingUrl: 'https://example.com',
}).then(chrome => {
  console.log(`Chrome debugging port running on ${chrome.port}`);
  const options = {
    flags: {
      chromeFlags: '--headless',
      port: chrome.port,
      runs: 1,
    },
  };
  const pwMetrics = new PWMetrics('http://example.com/', options);
  return pwMetrics.start();
});
