Overview
GraphQL is a query language and runtime for APIs. It provides a strongly-typed schema and allows clients to request exactly what data they need.
Why GraphQL?
- Flexible Queries: Request only needed data.
- Strongly Typed: Full schema validation.
- Single Endpoint: One endpoint instead of many.
- Real-time: Subscriptions for real-time updates.
- Developer Experience: Excellent tooling and documentation.
