A very simple script that periodically checks the availability of pre-selected "bags" (comma separated list of item ids in the TGTG_ITEM_IDS environment variable) on TooGoodToGo, and sends a notification for each available ones, if any.
The script automatically deploys to & runs on Scaleway's Serverless Functions (which has a generous free tier, so this basically costs nothing to run), deployed with GitHub Actions & Serverless Framework and mainly depends on the tgtg library.
