GraphQL is a query language for APIs that provides a more efficient and powerful alternative to REST. It allows clients to request exactly the data they need, reducing over-fetching and under-fetching issues. Here's a quick guide to get started:
Key Features ✅
- Type System: Define data structures with clear schemas.
- Flexible Queries: Fetch nested data in a single request.
- Cache-Friendly: Optimized for HTTP caching and performance.
- Real-Time Updates: Support for subscriptions (e.g., WebSocket).
Use Cases 🚀
- Data Aggregation: Combine data from multiple sources.
- API Versioning: Evolve APIs without breaking existing clients.
- Frontend-Backend Communication: Precise data control for SPAs.
- Reduced Roundtrips: Minimize requests for complex data needs.
