GraphQL

GraphQL is a query language and runtime for APIs that allows clients to request exactly the data they need from a server, reducing over-fetching and under-fetching of data. It provides a flexible and efficient alternative to traditional REST APIs by enabling declarative data fetching and a single endpoint for all queries.

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

Why learn GraphQL?

Developers should learn GraphQL when building modern web or mobile applications that require complex data interactions, such as e-commerce platforms, social media apps, or real-time dashboards, as it improves performance and developer experience. It is particularly useful in microservices architectures or when integrating multiple data sources, as it simplifies API management and reduces network overhead.
