Subscription Management (New & Improved!)

Member-Centric Subscription Management

The subscription management has been completely overhauled for a much better user experience:

1. Access Member Subscriptions: In the Members tab, click the "Subscriptions" button next to any member
2. Visual Toggle Interface: See all available mailing lists with modern toggle switches
3. Intuitive Controls:
   • Green toggle = Member is subscribed
   • Gray toggle = Member is not subscribed
   • Click anywhere on a list item to toggle subscription
4. Batch Operations: Make multiple changes and save them all at once
5. Real-time Feedback: The save button shows how many changes you've made

Benefits Over Previous System

• ✅ Much faster - No need to add subscriptions one by one
• ✅ Visual - See all subscriptions at a glance with color coding
• ✅ Intuitive - Toggle switches work like modern mobile apps
• ✅ Batch operations - Change multiple subscriptions simultaneously
• ✅ Less error-prone - Clear visual feedback prevents mistakes
• ✅ Change tracking - Only saves actual changes, not unchanged items

Mailing Lists

• View all mailing lists in a clean table
• Create new lists with name, email, and description
• Edit existing list details
• Delete lists with confirmation
• View member count for each list
• Status indicators (Active/Inactive)

Members

• View all members with their details
• Add new members with name and email
• Edit member information
• Delete members with confirmation

• Status management

Subscriptions

• Member-centric subscription management - Click on any member to manage their subscriptions
• Interactive toggle interface - Check/uncheck lists with visual toggles
• Batch changes - Make multiple subscription changes and save them all at once
• Real-time feedback - See subscription status instantly with visual indicators
• Subscription overview - View all subscriptions organized by list

User Experience

API Integration

The frontend communicates with the FastAPI backend through a comprehensive API client:

• Authentication - Bearer token authentication
• Error Handling - Automatic error parsing and user-friendly messages
• Loading States - Integrated loading indicators
• Data Validation - Client-side form validation before API calls

Customization

Styling

The CSS uses CSS custom properties (variables) for easy theming:

:root {
    --primary-color: #2563eb;
    --success-color: #10b981;
    --danger-color: #ef4444;
    /* ... more variables */
}

Configuration

The API client automatically detects the backend URL based on the current hostname and can be configured for different environments.

Browser Support

• Modern browsers (Chrome 60+, Firefox 55+, Safari 12+, Edge 79+)
• Mobile browsers (iOS Safari 12+, Chrome Mobile 60+)
