Summary

Implemented the Secure Payment Gateway and Payment Service as described in issue #1.

Changes Made

  1. Added Stripe SDK - Installed stripe package v16.0.0

  2. Implemented real createPaymentIntent - Replaced stub with actual Stripe integration:

    • Validates amount is required and must be a positive integer
    • Defaults currency to 'usd' if not provided
    • Uses STRIPE_SECRET_KEY env variable (no hardcoded keys)
    • Returns clientSecret and paymentId
    • Handles Stripe API errors with meaningful messages
  3. Added tests - 8 test cases covering:

    • Amount validation (missing, non-number, zero, negative, float)
    • Currency default behavior
    • Successful response structure

Checklist

  • stripe npm package installed
  • STRIPE_SECRET_KEY environment variable used
  • Amount validation with descriptive errors
  • Currency defaults to 'usd'
  • Real stripe.paymentIntents.create() call made
  • Returns clientSecret and paymentId
