GraphQL is a query language for APIs that lets clients request exactly the data they need, developed by Facebook as an alternative to REST APIs.
GraphQL is a query language and runtime for APIs developed by Facebook (now Meta) in 2012 and open-sourced in 2015. Unlike REST APIs where each endpoint returns a fixed data structure, GraphQL allows clients to specify exactly what data they need in a single request, reducing over-fetching and under-fetching.
At iConcept, we implement GraphQL APIs for projects that require flexible, efficient data fetching. It's particularly valuable for applications with complex data relationships, mobile apps where bandwidth efficiency matters, and projects where the frontend and backend teams work independently with different data requirements.
GraphQL is a query language for APIs that allows clients to request exactly the data they need. Developed by Facebook, it provides a complete description of the data in your API and gives clients the power to ask for exactly what they need — nothing more, nothing less.
GraphQL is used for building efficient APIs where clients need flexible data fetching. It's common in mobile applications (reducing bandwidth), complex web apps with many data relationships, and microservices architectures where a single gateway aggregates data from multiple services.
GraphQL is implemented by defining a schema that describes your data types and their relationships, then writing resolvers that fetch the actual data. Clients send queries specifying exactly which fields they need. Popular tools include Apollo Server, Hasura, and libraries for every major programming language.
