🔗GraphQL Schema Design
Master the schema patterns that separate elegant GraphQL APIs from production nightmares — from connection-based pagination to dataloader batching — by designing one end-to-end product schema along the way.
Phase 1The Client-Driven Mindset
Build the client-driven mental model behind every schema
Your schema is a question, not a table
6 minYour schema is a question, not a table
Non-null is a contract, not a hint

One query, many shapes

Phase 2Pagination Patterns That Scale
Refactor naive schemas into connection-based pagination patterns
Offset pagination breaks at scale

Phase 3Solving N+1 With Dataloaders
