A NestJS commerce backend requires modular architecture for auth, product, cart, order, and payment domains. Using Prisma ORM with PostgreSQL ensures consistent module design, enforcing BigInt for monetary values and encrypted customer identifiers for data integrity.

Handling PortOne payment webhooks requires implementing idempotent webhook endpoints within your NestJS API. The process involves verifying payment status through PortOne, confirming orders, and distributing referral ledger payouts while ensuring robust idempotency to prevent duplicate processing.

The best way to represent monetary values in a Prisma PostgreSQL schema is using BigInt. This approach prevents floating-point precision errors common in financial calculations, ensuring robust data integrity for commerce backend operations like order totals and payouts.

Generating OpenAPI schemas and shared types from a NestJS backend involves standardizing your API module design. You scaffold the apps/api modules, configure OpenAPI generation, and publish the resulting shared types for front-end consumption to maintain API contract consistency.

Yes, the NestJS commerce blueprint supports a referral payout system. It defines specific modules for referral and payout domains, describing how to distribute referral ledger entries after successful PortOne payment verification and order confirmation.

You should use BigInt for commerce API design to avoid floating-point rounding errors during financial calculations. Standard numbers lose precision with large values, whereas BigInt enforces strict data integrity for monetary amounts in your PostgreSQL database via Prisma.
