Headless Chrome Node API and Puppeteer installation

Update Nov-18: You don't require the --no-sandbox flag any longer, you should use the headless:false property in the object you send to .launch()

const browser = await puppeteer.launch({
    headless: false,
    slowMo: 80,
    args: ['--window-size=1920,1080']
    });

Also make sure you have all the required debian dependencies installed:

sudo apt-get install gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

Based on https://github.com/GoogleChrome/puppeteer

You only have to run the following command in Ubuntu 18.04

npm i puppeteer

Unfortunately this is not enough.

You will require the following Dependencies

sudo apt-get install gconf-service libasound2 libatk1.0-0 libatk-bridge2.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget

After which if you run it as per their example , you will receive an error

    (node:28469) UnhandledPromiseRejectionWarning: Error: Failed to launch chrome!
[1025/150325.817887:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

The solution to this is

const browser = await puppeteer.launch({args: ['--no-sandbox']});

Adding --no-sandbox

It will work accordingly then. The full working source code is below

    const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({args: ['--no-sandbox']});
  const page = await browser.newPage();
  await page.goto('http://owlcommand.com');
  await page.screenshot({path: 'example.png'});

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

Solution to [email protected]~install: cannot run in wd %s %s (wd=%s)

npm install --unsafe-perm

Screenshot Size

The default is really small, if the page you are testing is responsive, you can test it with different viewport settings. You can change its dimensions via the setViewport method.

await page.setViewport({
  width: 1600, 
  height: 1000
});
