GraphQL

GraphQL is a query language and runtime for APIs that allows clients to request exactly the data they need, reducing over-fetching and under-fetching issues common in REST APIs. It provides a strongly typed schema to define data structures and enables efficient data fetching from multiple sources in a single request.

Also known as: GraphQL API, GraphQL Server, GQL, Graph QL, Graphql

Why learn GraphQL?

Developers should use GraphQL when building APIs for applications with complex data requirements, such as mobile apps, single-page applications, or microservices architectures, as it improves performance and developer experience. It is particularly valuable in scenarios where clients need flexible data queries, real-time updates via subscriptions, or integration with diverse backend systems.
