- **Authentication**: Secure user authentication via StackAuth with NeonAuth integration - **Database**: User data stored in Neon PostgreSQL - **Payments**: Subscription management with Stripe - **Features**: User profiles, theme customization, email management ## Setting Up on v0 ### Step 1: Fork the Project 1. Click the "Fork" button in the v0 interface to create your own copy of this project 2. Give your project a name and description ### Step 2: Connect Neon Database 1. v0 will automatically prompt you to create or connect a Neon database 2. Follow the prompts to connect your Neon database to the project 3. All necessary environment variables will be automatically configured ### Step 3: Set Up NeonAuth in Neon Dashboard 1. After connecting your Neon database, go to the [Neon dashboard](https://console.neon.tech/) 2. Navigate to your project 3. In the sidebar, find and select "NeonAuth" 4. Follow the setup wizard to configure StackAuth: - Create a new StackAuth project if you don't have one - Connect your existing StackAuth project if you already have one 5. The NeonAuth setup will automatically: - Create the `neon_auth.users_sync` table - Configure the synchronization between StackAuth and your Neon database - Set up the necessary environment variables for StackAuth ### Step 4: Set Up Stripe 1. Create an account at [Stripe](https://stripe.com/) 2. Get your API keys from the Stripe dashboard 3. Add your Stripe secret key to the environment variables in v0: - `STRIPE_SECRET_KEY`: Your Stripe secret key 4. Create a product and price in the Stripe dashboard 5. Update the price ID in `app/api/stripe/plans.ts` \`\`\`typescript // In app/api/stripe/plans.ts const defaultPlans = [ { id: "FREE", priceId: undefined, // ... }, { id: "PRO", priceId: "YOUR_PRICE_ID_HERE", // Replace with your Stripe price ID // ... }, ] \`\`\` ### Step 5: Register Stripe Webhook After deploying your application, run the webhook registration script to set up Stripe webhooks: \`\`\`bash # Make sure your environment variables are set npx tsx register-webhook.ts \`\`\` This will: 1. Register a webhook endpoint with Stripe 2. Configure it to listen for subscription events 3. Provide you with a webhook secret Add the webhook secret to your environment variables as `STRIPE_WEBHOOK_SECRET`. ## Understanding NeonAuth NeonAuth is a feature of Neon that integrates with StackAuth to: 1. Automatically sync user data from StackAuth to your Neon database 2. Create and maintain a `neon_auth.users_sync` table with user information 3. Allow you to join user data with your application tables Example of querying user data: \`\`\`sql -- Get all active users SELECT * FROM neon_auth.users_sync WHERE deleted_at IS NULL; -- Join with application data SELECT t.*, u.id AS user_id, u.name AS user_name, u.email AS user_email FROM public.todos t LEFT JOIN neon_auth.users_sync u ON t.owner = u.id WHERE u.deleted_at IS NULL; \`\`\` ## Local Development For local development with Stripe webhooks, use the Stripe CLI: \`\`\`bash stripe listen --forward-to http://localhost:3000/api/stripe \`\`\` ## Project Structure - `/app`: Next.js App Router pages and components - `/app/api`: API routes including Stripe webhook handler - `/app/components`: Reusable UI components - `/lib`: Utility functions and database client - `/stack.ts`: StackAuth configuration ## Customization ### Modifying Subscription Plans Edit the plans in `app/api/stripe/plans.ts` to change the available subscription tiers and their features. ## Stripe Webhook Setup To enable Stripe webhooks for subscription management, you need to register a webhook endpoint with Stripe. This project includes a script to automate this process. ### Register Webhook Run the following command to register a webhook with Stripe: \`\`\`bash # Make sure your Stripe secret key and deployment URL are set in your environment npx tsx register-webhook.ts \`\`\` The script will: 1. Check if a webhook already exists for your URL 2. Create a new webhook or update an existing one 3. Configure it to listen for relevant subscription events 4. Provide you with a webhook secret **Important:** Add the webhook secret to your environment variables.

Uses Redis sorted sets for notifications and Redis sets for watchers. ## Architecture ### Fan-out System The notification system uses a fan-out on write approach, where notifications are dispatched to all watchers at the time of the event: 1. **Watcher Management** - Each task has a Redis Set (`watchers:{taskId}`) containing user IDs - O(1) membership checks for efficient watcher validation - O(1) add/remove operations for watch toggling 2. **Notification Storage** - Uses Redis Sorted Set (`notifications`) for time-based operations - Score: timestamp in milliseconds - Member: JSON stringified notification object - Enables efficient range queries for "notifications since X" - O(log N) insertion, O(log N + M) range queries where M is result size 3. **Fan-out Process** \`\`\`ts async function notifyWatchers({ taskId, message, type = 'info' }) { // 1. Get all watchers O(N) const watchers = await getTaskWatchers({ taskId }) // 2. Fan out to each watcher O(N * log M) where M is notifications size await Promise.all( watchers.map((userId) => createNotification({ userId, message, type, taskId, }), ), ) } \`\`\` ### Key Design Decisions 1. **Why Redis Sets for Watchers** - Fast membership checks for watch status - Automatic deduplication of watchers - Space efficient for large watcher lists 2. **Why Sorted Sets for Notifications** - Natural time-based ordering - Efficient pagination and "since" queries - Score (timestamp) enables version control for polling 3. **Why Fan-out on Write** - Immediate consistency for real-time updates - Simpler read path (no aggregation needed) - Trade-off: Higher write latency for faster reads ## Storage - Notifications: Stored in Redis sorted set with timestamp as score - Watchers: Stored in Redis sets (one set per task) ## Features - Real-time notifications for task updates - Watch/unwatch tasks - Mark notifications as read/unread - Notification types: success, warning, info ## Usage ### Watching Tasks \`\`\`ts // Add a watcher await watchTask({ taskId, userId, }) // Remove a watcher await unwatchTask({ taskId, userId, }) // Get all watchers const watchers = await getTaskWatchers({ taskId }) \`\`\` ### Notifications \`\`\`ts // Create a notification await createNotification({ userId, type: 'info', message: 'Task updated', taskId, }) // Notify all watchers await notifyWatchers({ taskId, message: 'Task completed', type: 'success', }) \`\`\` ### Polling for Updates \`\`\`ts // Client-side polling using version (timestamp) for efficiency async function pollNotifications() { const { notifications, version } = await getNotificationsSince({ userId, version: lastVersion, }) lastVersion = version return notifications } \`\`\` ## Where it's used - Authentication and user management system - Basic notification infrastructure ## UI Components - Notifications menu (`app/components/notifications.tsx`): Global notifications dropdown ## Performance Characteristics - Watcher operations: O(1) - Notification creation: O(log N) - Get notifications since: O(log N + M) where M is result size - Fan-out: O(W \* log N) where W is watcher count and N is notification count - Storage: O(N) for notifications, O(W) for watchers per task [V0_FILE]typescript:file="app/api/notifications/[id]/mark-read/route.ts" isMerged="true" import { NextResponse } from
