# Library Availability Monitor
A Node.js service that monitors San Diego libraries for parking pass availability and sends notifications via ntfy when passes become available at the Rancho Penasquitos branch.
## Features
- 📚 Monitors specific library book availability via BiblioCommons API
- 📱 Sends push notifications via ntfy when new books become available
- ⏰ Polls hourly and tracks availability changes
- 🔄 Graceful error handling and recovery
- 🧪 Comprehensive testing suite
- 🎭 Mock testing capabilities
- 🚀 Easy deployment to Linux servers
## Setup
### Prerequisites
- Node.js 18+
- npm
- SSH access to deployment server (optional)
### Installation
1. Clone or download this repository
2. Install dependencies:
```bash
npm install
```
3. Configure your ntfy settings in `index.js`:
```javascript
const CONFIG = {
NTFY_TOPIC: 'your-topic-name',
NTFY_SERVER: 'https://ntfy.sh', // or your own server
// ... other settings
};
```
## Usage
### Running the Monitor
```bash
# Start the monitor
npm start
# Development mode with auto-restart
npm run dev
```
### Testing
```bash
# Run all tests
npm test
# Validate against real API response example
npm run validate
# Interactive mock testing
npm run mock
# Simulate availability changes
node mock.js test 3 # Simulate 3 available books
node mock.js notify # Send test notification
node mock.js status # Show current state
node mock.js reset # Reset state file
```
### Deployment
The included deployment script uploads and manages the service on a remote Linux server:
```bash
# Deploy to configured server
npm run deploy
# Or run directly
./deploy.sh
```
#### Deployment Setup
1. Configure SSH access to your server as 'linode' in `~/.ssh/config`:
```
Host linode
HostName your-server-ip
User your-username
IdentityFile ~/.ssh/your-key
```
2. The deployment script will:
- Upload files to `/opt/sd-park-pass-ntfy`
- Install dependencies
- Create and start a systemd service
- Enable auto-start on boot
## Configuration
### Main Configuration (index.js)
```javascript
const CONFIG = {
API_URL: 'https://gateway.bibliocommons.com/v2/libraries/sandiego/bibs/S161C1805116/availability',
BRANCH_NAME: 'Rancho Penasquitos',
NTFY_TOPIC: 'sdparkpass',
NTFY_SERVER: 'https://ntfy.sh',
POLL_INTERVAL: '0 * * * *', // Every hour
// ...
};
```
### Systemd Service
The service runs as user `nobody` for security and includes:
- Automatic restart on failure
- Proper logging via journald
- Security hardening
- Environment isolation
View logs:
```bash
sudo journalctl -u sd-park-pass-ntfy -f
```
## API Response Format
The monitor expects BiblioCommons API responses in this format:
```json
{
"entities": {
"bibItems": {
"1805116|31336107103179||76": {
"collection": "Adult - Circulation Desk",
"callNumber": "CA STATE LIBRARY PARKS PASS HIKING BACKPACK",
"itemId": "1805116|31336107103179||76",
"branch": {
"name": "Rancho Penasquitos",
"code": "29"
},
"availability": {
"status": "AVAILABLE",
"statusType": "AVAILABLE",
"libraryStatus": "Available"
},
"branchName": "Rancho Penasquitos",
"dueDate": null
}
}
}
}
```
The monitor looks for:
- Items with `branchName` containing "Rancho Penasquitos"
- Items with `availability.statusType` NOT equal to "UNAVAILABLE"
- Available status types include: "AVAILABLE", "RECENTLY_RETURNED"
## State Management
The monitor tracks availability in `last_availability.json`:
```json
{
"availabilityCount": 2,
"lastUpdated": "2025-07-13T10:00:00.000Z",
"previousCount": 1,
"branch": "Rancho Penasquitos",
"apiUrl": "https://..."
}
```
## Notification Types
- 📚 **High Priority**: New books became available
- ⚠️ **Low Priority**: Errors or status changes
- 🔴 **Service Events**: Start/stop notifications
## Troubleshooting
### Common Issues
1. **No notifications received**:
- Check ntfy topic subscription on your phone
- Verify NTFY_SERVER and NTFY_TOPIC settings
- Test with `node mock.js notify`
2. **API errors**:
- Check network connectivity
- Verify API URL is still valid
- Monitor rate limiting
3. **Service not starting**:
- Check file permissions
- Review systemd logs: `journalctl -u sd-park-pass-ntfy`
- Ensure Node.js is installed on server
### Mock Testing
Use the mock script to verify functionality:
```bash
# Interactive mode
node mock.js
# Commands in interactive mode:
> test 5 # Simulate 5 available books
> notify # Send test notification
> status # Show current state
> reset # Clear state file
> quit # Exit
```
