Too Good To Go - Notifier monitors your favorite TGTG Store for newly available items.
Supports multiple accounts and notifiers type (new type of notifiers will be added later).
I made it for my personal use only, but it may also be useful to someone else.

git clone https://github.com/Nyrrell/tgtg-notifier.git
cd tgtg-notifier

To run this project, you will need to create a config.json file, see below or use example.config.json to set your configuration.

• Set global parameters if needed timezone (default: UTC), locale (default: en-US)
• To improve i18n, you can set available & price for translate in your language, it's totally optional.
• For each account, be sure to fill these fields notifiers and email (optionally accessToken and refreshToken if you already have it).

{
  "accounts": [
    {
      "email": "Too Good To Go email",
      "accessToken": "Too Good To Go Access Token goes here if you have it",
      "refreshToken": "Too Good To Go Refresh Token goes here if you have it",
      "notifiers": [
        {
          "type": "discord",
          "webhookUrl": "https://discord.com/api/webhooks/123456789/ABCDEFG123456789"
        },
        {
          "type": "gotify",
          "apiUrl": "https://gotify.net",
          "token": "RFRNGDQmCgboyVF"
        }
      ]
    }
  ],
  "timezone": "Europe/Paris",
  "locale": "fr-FR",
  "language": {
    "available": "Disponible",
    "price": "Prix"
  },
  "cronSchedule": "*/5 6-22 * * *",
  "sendStartNotification": true,
  "testNotifiers": false,
  "logLevel": "info"
}

Configuration can be provided via:

1. Environment variables (highest priority)
2. config.json

First you need to install Node.js 22.14.0 or higher

npm install
npm run build
npm run start

If you don't set accessToken and refreshToken, Too Good To Go will send you an email containing a PIN code.

Enter the PIN code when prompted, a small HTTP server starts automatically. Check the logs for a line like:

Enter your PIN here → http://localhost:3000

Open that URL in your browser, paste the PIN, and click OK. The container will then complete the login and start monitoring.

Once logged in, the accessToken and refreshToken are saved automatically. You can copy them into config.json to skip the login step on future restarts.

After that, tgtg-notifier starts monitoring your favorite stores and sends you a notification whenever stock becomes available.

A Dockerfile is available in the repository to build a ready-to-run Docker image.
You need to map the volumes to use your config.json file and a folder for the application's logs.

docker build -t tgtg-notifier .
docker run --name tgtg-notifier -d \
  -p 3000:3000 \
  -v ./config.json:/usr/app/config.json \
  -v ./logs/:/usr/app/logs \
  tgtg-notifier

Make sure port 3000 is exposed.

You can also customize the port via the PORT environment variable or config.json.

If you prefer to use Docker Compose, a docker-compose.yml configuration file is also available.

docker-compose up -d

You will need to create two configuration files in your Systemd user directory : ~/.config/containers/systemd/
