Extract Netlify env vars

extract-netlify-env-vars.js

/* Prints env vars from Netlify deploy settings UI to
 * the JavaScript console.
 *
 * Usage: go to the build & deploy settings section of
 * a Netlify site, then run this script.
 */
const envVars = $("#section-environment").querySelectorAll("dl");

const output = [].reduce.call(envVars, (str, dl) => {
  const name = dl.querySelector("dt").innerText;
  const value = dl.querySelector("dd").innerText;

  return str + `${name}=${value}\n`;
}, "");

console.log(output);

Note: env vars are already sorted on the Netlify UI page so there is no need to implement sorting here.
