stock-checker

Node.js service that periodically checks if products from online stores are in stock. Sends notifications when items come back in stock via SMS using Twilio.

Prerequisites

• Node.js
• npm
• Google Chrome (or any Chromium-based browser)
  • stock-checker uses Puppeteer to open product pages and read their contents. Although Puppeteer's bundled Chromium could be used, this will likely fail on some websites due to bot prevention mechanisms. Using a local instance of Chrome that you use for your daily browsing means that the traffic generated by stock-checker will be virtually indistinguishable from organic traffic.
• A Twilio account

Getting started

1. Clone the repository.
2. npm install
3. Copy the data.example directory and rename it data.
4. In the data directory, configure config.yml, products.yml and recipients.yml as desired.
   • If you need to add a product from an unsupported website, have a look at adding support for it in src/providers.js.
5. npm start
   • stock-checker will check the stock of your defined products every 3 to 10 minutes, and send out notification SMS messages to defined recipients when the stock status changes.
   • Don't delete the data/lastStockMap.json file as it is used to store the last known stock state. This prevents sending duplicate messages when a product comes back in stock.
