Davidasix/stripe integration

[DavidASix]

This pull request introduces a subscription management feature, including a subscription page, API endpoints, middleware, and database updates. It also refactors existing code to integrate with the new subscription system. Below are the most important changes grouped by theme:

Subscription Page and User Interface

• Added a new SubscriptionPage component in src/app/(product)/subscription/page.tsx to display the user's subscription status, calculate remaining days, and provide a "Subscribe Now" button that redirects to a Stripe checkout session.
• Updated PricingOptions in src/components/common/pricing-options.tsx to remove inline checkout logic and redirect users to the subscription page for subscribing. [1] [2] [3]

API Endpoints

• Added a GET endpoint in src/app/api/purchases/check-active-subscription/route.ts to check if a user has an active subscription using the withActiveSubscription middleware.
• Added a webhook handler in src/app/api/purchases/webhook/route.ts to process Stripe events like checkout.session.completed and invoice.payment_succeeded, updating user records and logging subscription payments.

Middleware

• Introduced withActiveSubscription middleware in src/middleware/withActiveSubscription.ts to check if a user has an active subscription based on the subscription_payments table.

Database Schema

• Added a stripe_customer_id column to the user table and created a new subscription_payments table to track subscription payments. These changes were implemented in the migration file src/schema/migrations/0007_fantastic_jazinda.sql.
• Updated the users table schema in src/schema/schema.ts to include the new stripe_customer_id column.

Refactoring and Updates

• Renamed the checkout endpoint URL in src/app/api/purchases/initialize-checkout/schema.ts from /checkout-context to /initialize-checkout.
• Updated the success and cancel URLs in the Stripe checkout session to point to the subscription page instead of the purchases page.
• Adjusted the price_id for the "All Access" product in src/lib/products.ts to dynamically switch between development and production environments.

src/app/api/purchases/webhook/route.ts:21

• The webhook handlers for Stripe events (e.g., checkout.session.completed) currently lack automated tests. Consider adding unit or integration tests to validate that errors, retries, and database updates behave correctly.

const handleCheckoutSessionCompleted: Handler = async ({ type, data }) => {

src/app/api/purchases/check-active-subscription/route.ts:16

• The check-active-subscription endpoint is critical for guarding feature access but doesn't appear to have any tests. Adding API tests would help ensure correct JSON structure and error handling.
