This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).

## Notification Setup (Discord/Telegram)

To receive alerts when someone cancels a cat sitting slot, you can configure a Webhook in the **Settings** menu of your dashboard.

### 👾 Discord
1. Open your Discord server and go to **Server Settings** > **Integrations** > **Webhooks**.
2. Click **New Webhook**, name it (e.g., "Cat Sitting Bot"), and select the desired channel.
3. Click **Copy Webhook URL**.
4. Paste this URL into the **Notification Webhook** field in the plan settings.

### ✈️ Telegram
Telegram doesn't support simple Webhooks natively for users. The easiest way is using a bridge like **Intergram**:
1. Open Telegram and search for the `@IntergramBot`.
2. Send `/start` to get your unique **Chat ID**.
3. Your Webhook URL will be: `https://www.intergram.xyz/msg/YOUR_CHAT_ID`
4. Paste this URL into the **Notification Webhook** field in the plan settings.

*Note: The app sends notifications automatically whenever a booking is deleted.*

## 🐳 Deployment (Docker)

The easiest way to host the Cat Sitting Planner is via Docker.

### 1. Build & Run
```bash
docker-compose up -d --build
```

### 2. Persist & Backup Data (Important)
All coordination data is stored in a single SQLite file at `/app/data/dev.db` inside the container. 

To ensure your plans are safe:
1. **Always map a volume** to `/app/data`.
2. **Backups**: Simply copy the `dev.db` file from your host path (e.g., `/mnt/user/appdata/csp/dev.db`).
3. **Upgrades**: As long as the volume mapping stays the same, your data will survive container updates.
4. **Moving Systems**: If you move the app, copy your existing `dev.db` into the new host data folder **before** starting the container.

**Example `docker-compose.yml` volumes:**
```yaml
volumes:
  - /mnt/user/appdata/csp:/app/data
```
