TypeScript API Design Patterns FAQs

Question 1

What is the benefit of cursor-based pagination over offset?

Accepted Answer

Cursor-based pagination is more stable for large datasets as it avoids item skipping or duplication when records are inserted and is significantly more performant for databases using index seeks.

Question 2

Does this skill work with specific frameworks like Express or NestJS?

Accepted Answer

Yes, while the principles are framework-agnostic, the implementation patterns are designed in TypeScript and are easily adaptable to any modern web framework like Express, Fastify, or NestJS.

Question 3

Why does this skill recommend versioning APIs in the URL?

Accepted Answer

Versioning in the URL path (e.g., /v1/users) makes testing, debugging, and caching much easier for developers and client consumers compared to header-based versioning.

Question 4

What is RFC 7807?

Accepted Answer

It is a standard for 'Problem Details for HTTP APIs', providing a consistent, machine-readable way to return error messages that include type, status, title, and detail fields.

Question 5

How does this skill handle API idempotency?

Accepted Answer

It provides patterns for implementing Idempotency-Key headers, ensuring that non-idempotent operations like POST and PATCH can be safely retried without unintended side effects.
