Cursor pagination in GraphQL only works if you treat cursors as untrusted input, commit to an immutable sort contract, and monitor the specific ways keyset pagination fails.
Replace scattered inline validation with a single declarative contract. A practical look at JSON Schema at the API boundary, with a working ajv example and the additionalProperties trade-off.
When an API returns different event shapes, documenting them clearly is hard. This post shows how OpenAPI 3.x’s oneOf and discriminator can model such polymorphic responses, with a live example, trade‑offs, and best‑practice checklist.
The Twitter (X) API v2 returns IDs instead of usable objects by default. The expansions parameter hydrates authors, media, and referenced tweets in one request — here's how to use it without bloating payloads.
Ruby 3.0's case/in pattern matching replaces nested conditionals with declarative data deconstruction. A worked webhook example, guards, pins, and the trade-offs.
FastAPI's Depends system is where shared logic should live. Here's how yield-based dependencies, scoping, and sync-vs-async choices work in practice — and where the pattern breaks down.
Write one OpenAPI file and let it drive request validation, generated clients, and docs. A worked POST /orders example, the operationId trap, and the 3.0 vs 3.1 pitfalls.
Learn how Prisma Client’s cursor‑based pagination gives stable, type‑safe pages for APIs, with a concrete example, trade‑offs, and steps to verify the approach.
Learn when to use an OpenAPI discriminator for polymorphic schemas, how it compares to oneOf/anyOf, and see a concrete Pet API example with validation steps.
