Overview
GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
Key Concepts
- Schema: Defines the types and relationships in your data.
- Queries: Clients specify exactly which fields they want.
- Mutations: Used to modify data on the server.
- Subscriptions: Real-time updates via WebSockets.
Benefits
- No Over-fetching: Clients get only the data they requested.
- Strongly Typed: The schema ensures data consistency.
- Single Endpoint: All data is accessed through one URL.
