GraphQL

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

Also known as: Graph QL, Graphql, GQL, Graph Query Language, GraphQL API

Why learn GraphQL?

Developers should learn GraphQL when building modern web or mobile applications that require flexible, efficient data fetching, such as in complex frontend-backend integrations or microservices architectures. It's particularly useful for scenarios where clients need to avoid multiple round-trips to servers or when APIs must evolve without breaking existing queries.
