Techniques to Protect Your GraphQL API
summary
Covers concrete defenses: enforce trusted documents via persisted IDs to act as a document allow list, avoid automatic persisted queries for security, and run build‑time checks with tools like gql‑lint and gql‑check. Shows attacks and fixes: a 2MB upload can consume 1GB RAM so avoid file uploads over GraphQL, nested lists can explode into 40 million nodes so apply strict list depth and alias limits, use cancellation tokens, DataLoader batching, cursor pagination and per‑operation rate/complexity limits.
