Using with Puppeteer

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({
    args: ['--proxy-server=http://192.168.1.1:3128']
  });

  const page = await browser.newPage();

  // Authenticate with the proxy
  await page.authenticate({
    username: 'myuser',
    password: 'mypass'
  });

  await page.goto('https://httpbin.org/ip');
  const content = await page.content();
  console.log(content);

  await browser.close();
})();

const proxies = [
  { host: '192.168.1.1:3128', user: 'user1', pass: 'pass1' },
  { host: '192.168.1.2:3128', user: 'user2', pass: 'pass2' },
];

for (const proxy of proxies) {
  const browser = await puppeteer.launch({
    args: [`--proxy-server=http://${proxy.host}`]
  });
  const page = await browser.newPage();
  await page.authenticate({ username: proxy.user, password: proxy.pass });

  // Your automation logic here
  await page.goto('https://example.com');

  await browser.close();
}

// Headless (default) — faster, no visible window
const browser = await puppeteer.launch({
  headless: true,
  args: ['--proxy-server=http://192.168.1.1:3128']
});

// Headful — useful for debugging
const browser = await puppeteer.launch({
  headless: false,
  args: ['--proxy-server=http://192.168.1.1:3128']
});
