publix-coupon-clipper

Publix is a grocery chain that operates throughout the Southeastern United States. This script uses Puppeteer to automatically clip digital coupons which can then be applied to your purchases in store if you provide your phone number at checkout.

Command-line Usage

npx publix-coupon-clipper [email] [password]

If you do not provide your Publix.com email address and password the script will check the PUBLIX_EMAIL and PUBLIX_PASSWORD environment variables. If either of these are missing, you will be prompted for the value to use.

Avoiding the Large Chromium Download

When running `npx publix-coupon-clipper` the Puppeteer library will download Chromium each time (a >130Mb download as of writing). To avoid this you can set the `PUPPETEER_DOWNLOAD_PATH` environment variable to reuse the same download each time. For example: ```sh PUPPETEER_DOWNLOAD_PATH=/tmp/.publix-coupon-clipper-chromium npx publix-coupon-clipper ``` Alternatively you can set the `PUPPETEER_SKIP_CHROMIUM_DOWNLOAD` environment variable to `1` and `PUPPETEER_EXECUTABLE_PATH` to your existing Chrome install (eg. on macOS `'/Applications/Google Chrome.app/Contents/MacOS/Google Chrome'`). See the Puppeteer documentation on [environment variables](https://github.com/puppeteer/puppeteer/blob/main/docs/api.md#environment-variables) for more, but also note that they only [guarantee support](https://github.com/puppeteer/puppeteer/#q-why-doesnt-puppeteer-vxxx-work-with-chromium-vyyy) for their bundled Chromium version.

Package Usage

publix-coupon-clipper can also be installed from NPM and used in your own Node.js script.

const { clipCoupons } = require("publix-coupon-clipper");

(async () => {
  const couponCount = await clipCoupons({
    publixEmail: "foobar@example.com",
    publixPassword: "letmein",
  });

  console.log(`Coupons clipped: ${couponCount}`);
})();

You can optionally provide your own Puppeteer browser instance to use:

const { clipCoupons } = require("publix-coupon-clipper");
const puppeteer = require("puppeteer");

(async () => {
  const browser = await puppeteer.launch({
    headless: false,
  });

  await clipCoupons({
    publixEmail: "foobar@example.com",
    publixPassword: "letmein",
    browser,
  });

  // Don’t forget to dispose of your browser!
  await browser.close();
})();

An EventEmitter called events is also exported which provides info messages that are useful for logging progress:

const { clipCoupons, events } = require("publix-coupon-clipper");

(async () => {
  events.on("info", (message) => console.log(new Date(), message));

  await clipCoupons({
    publixEmail: "foobar@example.com",
    publixPassword: "letmein",
  });
})();
