feat: subscription implementation

[jediahjireh]

We need to implement a subscription system that allows users to subscribe through a selection process from either the landing page CTA (Call-to-Action) or the user dashboard. The subscription flow should be integrated into the user interface, backend schema, and payment system. Creating pricing component would be advised.

---

⭐️ goal:

Create a user-friendly subscription system that enables users to sign up for subscription plans, via the landing page or the user dashboard, with seamless backend handling and integration to support payment processing.

---

🐣 expected outcome:

• A clear, well-integrated subscription option for users, whether on the landing page or the dashboard.
• The ability to manage user subscriptions and link them with a payment service (e.g., Stripe, PayPal, Payfast, Peach Payments, etc.).
• Seamless communication with the backend for subscription status updates.
• Subscription management from the user dashboard, including viewing active plans, upgrading/downgrading plans, and handling cancellations.
• Ensure all data is stored securely and appropriately in the backend, with necessary schema updates.

---

🩰 tasks:

1. Schema Design (Backend)

   • Design the schema for subscriptions in the backend to track the subscription status of users.

   • This will include user-specific subscription details such as the plan they are on, the subscription start date, expiration date, payment method, and status (active/cancelled/expired).

   • Define a subscriptions table or collection in the database with necessary fields:

     • userId (Foreign key to link to user)
     • plan (subscription plan selected by the user, e.g., Free, Basic, Premium)
     • status (active, cancelled, expired, etc.)
     • startDate (subscription start date)
     • endDate (subscription expiration date)
     • paymentMethod (payment method used for the subscription)
     • paymentStatus (pending, completed, failed)
     • autoRenew (automatically renew subscription monthly)

   • Consider integrating with the users schema for easier user-subscription management.

   model User {
     id            String      @id @default(cuid())
     email         String      @unique
     password      String
     role          String
   
     subscription  Subscription? @relation(fields: [subscriptionId], references: [id])
     subscriptionId String?
   }
   
   model Subscription {
     id        String   @id @default(cuid())
     plan      String
     status    String
   
     userId    String
     user      User     @relation(fields: [userId], references: [id])
   }

   • Ensure there is a clean mechanism to check for expired or cancelled subscriptions and alert the user.

2. User Interaction (UI/UX)

   • Update the UI for the subscription flow, both on the landing page and the user dashboard.

   • Users should be able to:

     • View available subscription plans.
     • Select a plan and proceed to payment.
     • See current subscription status on the user dashboard.

   • Create or update the CTA on the landing page to include options for viewing and subscribing to plans.

   • Design an interactive UI for the subscription section in the dashboard that displays:
     - Current plan details (including plan name and expiration date).
     - Option to upgrade or downgrade plans.
     - Option to cancel the subscription.

   • Display relevant messages if the user’s subscription is about to expire or has expired.

3. Payment Integration

   • Integrate a payment provider (e.g., Stripe, PayPal) to handle payments securely.

   • This will be triggered from the landing page CTA or user dashboard based on the user’s subscription selection.

   • Implement payment integration, for chosen payment provider, in the backend. Handle the subscription payment process.

   • Create the necessary functionality to:

     • Initiate a payment process upon plan selection.
     • Confirm and verify payments.
     • Update the subscriptions schema based on payment status (successful/failed).

   • Ensure that once the payment is processed successfully, the user’s subscription is marked as active and the plan is updated.

   • Add functionality to handle payment retries in case of failure.

4. Subscription (Business Logic)

   • Handle user interactions with subscription logic, such as plan selection, subscription creation, cancellation, and status updates.

   • Create actions that handle:

     • Subscription selection on both the landing page and user dashboard.
     • Updating subscription status after successful payment.
     • Canceling a subscription.
     • Sending email confirmations or alerts when subscription status changes (e.g., renewal, cancellation).

   • Ensure all actions are properly connected to the backend schema for consistent data updates.

5. Deployment and Documentation

   • Ensure that the subscription feature is deployed smoothly, with proper database migrations and integrations.

   • Document the subscription flow and usage for future developers and administrators.

   • Update the database schema with necessary migrations to handle subscriptions.

   • Add detailed documentation explaining the subscription setup and management in the README.md.

   • Document any third-party services (e.g., Stripe) and their configuration.

---

Additional Considerations:

• Security: Ensure that payment details and subscription information are stored securely.
• Accessibility: Make sure the subscription UI is accessible and usable for all users, including those with disabilities.
• Error Handling: Implement clear error messages when payment fails or the subscription cannot be processed.
• Scalability: Plan for future subscription plans or changes in pricing.
