const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  var route = process.argv[2];
  var pageName = process.argv[3];
  await page.goto(route, {waitUntil: 'networkidle2'});
  await page.pdf({ path: pageName, scale: 1, landscape: true, printBackground: true, format: "A4", preferCSSPageSize: true, displayHeaderFooter: false, margin: { left: "10mm", right:"9.5mm",top:"10mm",bottom:"9.5mm"}})

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