03:12 - Scott's strategy

  • Go to Reddit and refresh until someone posts a link and then GO GO GO
  • Don't buy on sites that allow simple bots to work
  • TBH I don't know how to code this type of bot and would prob end up accidentally buying a ton of stuff

05:06 - Wes' strategy

  1. You need a way to find out of there is stock
    • Find out of there is an API endpoint you can hit (inspect element)
  2. If there is not, you'll need to scrape the site.
  3. Fetch(url). text()
  4. Regex
  5. Cheerio
  6. Puppeteer (slower, easier to run)
  7. Save any data that you want in a database. Text-based database is great.
  8. Re-run the scrape every N mins
  9. When there IS a match you can:
    • Send a text message - Twilio
    • Send an email - Postmark
    • Try to fill out the form and submit it yourself
      • document.querySelector()

11:35 - Things that get in the way

  • Blocked IP
    • Use a VPN
  • Captcha or Cloudflare
  • Run it on your local computer
  • Use Puppeteer to get all cookies and headers
