Node Script to Display Cookies

With some advice from StackOverflow, I wrote a short node script that I placed in the file $HOME/bin/get-cookies.js with the executive bit set via chmod +x $HOME/bin/get-cookies. It relies on the library puppeteer to control a browser instance of headless Chromium, which must be installed first via npm i puppeteer.

Then, you can call get-cookies.js to get all installed cookies upon request of the page given as a parameter (here: Note that Puppeteer creates its own Chromium user profile which it cleans up on every run.

Source Code of ‘get-cookies.js’

#!/usr/bin/env node

const puppeteer = require('puppeteer');

const url = process.argv[2];

(async () => {
  const browser = await puppeteer.launch({ headless: true, args: ['--disable-dev-shm-usage'] });
  try {
    const page = await browser.newPage();
    await page.goto(url, { waitUntil: 'networkidle2' });

    var cookies = await page._client.send('Network.getAllCookies');
    cookies = cookie => {
      cookie.expiresUTC = new Date(cookie.expires * 1000);

      return cookie;

    var persistantCookies = cookies.filter(c => {
      return !c.session;

      persistantCookies: persistantCookies,
      persistantCookiesCount: persistantCookies.length,
  } catch(error) {
  } finally {
    await browser.close();
