Answer 1

You can use Puppeteer (Headless Google Chrome Node API) to generate PDFs:

Puppeteer is a Node library which provides a high-level API to control Chrome or Chromium over the DevTools Protocol. Puppeteer runs headless by default, but can be configured to run full (non-headless) Chrome or Chromium.

You can easily generate a PDF using page.pdf():

'use strict';

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();

  await page.goto('https://example.com/');

  await page.pdf({
    path: 'example.pdf',
  });

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

Then you can execute the program straight from Node.js:

node puppeteer.js

Another approach, starting from scratch using PDFKit...

Install http://phantomjs.org/ and the install the phantom node module https://github.com/amir20/phantomjs-node

Here is an example of rendering a pdf

var phantom = require('phantom');

phantom.create().then(function(ph) {
    ph.createPage().then(function(page) {
        page.open("http://www.google.com").then(function(status) {
            page.render('google.pdf').then(function() {
                console.log('Page Rendered');
                ph.exit();
            });
        });
    });
});
