How to maximise Screen use in Pupeteer ( non-headless )

Question

I'm testing out puppeteer for chrome browser automation ( previously using selenium but had a few headaches with browser not waiting until page fully loaded ) .

When I launch an instance of puppeteer - then it displays the contents taking up less than half the screen with scroll bars. How can I make it take up a full screen?

const puppeteer = require('puppeteer');

async function test(){
    const browser = await puppeteer.launch({
        headless: false,
      });
    const page = await browser.newPage();
    await page.goto('http://google.com')
}

test()

The initial page seems to load fine , but as soon as I access a page it makes it scrollable and smaller.

You probably would want to set a certain screen size, which any real browser has:

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.setViewport({ width: 1366, height: 768});
  await page.goto('https://example.com', {waitUntil: 'networkidle2'});
  await page.screenshot({path: 'example.png'});

  browser.close();
})();
