**Project**
- **Name:**: Simple WebUntis → PocketBase sync
- **Description:**: A small Node.js script that fetches your WebUntis timetable and synchronizes classes into a PocketBase collection.

**Files**
- **Main script:**: [index.js](index.js)
- **Package metadata:**: [package.json](package.json)
- **Dockerfile:**: [dockerfile](dockerfile)

**Requirements**
- **Node.js:**: v14+ recommended
- **Environment:**: A PocketBase instance reachable from the script (the URL is currently set inside `index.js`).

**Dependencies**
- **webuntis**: fetches timetable data
- **pocketbase**: PocketBase client
- **luxon**: date handling
- **dotenv**: load environment variables

**Configuration**
- **Environment variables:**: Create a `.env` in the project root with at least:

```
WEBUNTIS_SCHOOL=your_school
WEBUNTIS_USER=your_username
WEBUNTIS_PASS=your_password
WEBUNTIS_URL=your_webuntis_url
```

- **PocketBase URL:**: The script currently instantiates PocketBase with a hard-coded URL (`https://fsae41.de`). Edit `index.js` to change this or make it configurable via an env var.

**Install**

```bash
npm install
```

**Run**

```bash
node index.js
```

The script runs an initial sync and then repeats every 30 minutes (see `setInterval` near the end of `index.js`).

**Behavior**
- **Merging lessons:**: The script sorts and merges adjacent lessons that end and start at the same time on the same day.
- **PocketBase collection:**: Records are created/updated in the `classes` collection. Existing records are compared and updated if changes are detected.

**Docker**
- A `dockerfile` is present; you can containerize the app. Ensure environment variables and PocketBase URL are provided to the container.

**Notes & Next steps**
- Consider moving the PocketBase URL into `.env` for easier configuration.
- Add error handling and logging for production use.

**License**
- No license specified. Add one if you plan to publish.
