GraphQL is a query language for APIs that enables clients to request exactly the data they need. It provides a complete description of data with a strongly typed schema.
Key Concepts
Schema Definition Language (SDL)
Queries (read) and Mutations (write)
Resolvers and DataSources
Subscriptions for real-time
Fragments for reusable selections
Common Use Cases
Mobile apps with limited bandwidth
Complex data requirements
Rapid product iteration
BFF (Backend for Frontend)
Aggregating multiple services
Best Practices
Design schema around UI needs
Implement proper rate limiting
Use DataLoader to prevent N+1
Validate queries aggressively
Set query depth limits
