GraphQL vs. REST API: Context, Comparison, and Practical Use Cases
APIs are the foundation of modern application integration. They allow web applications, mobile apps, cloud platforms, and enterprise systems to exchange data without exposing their internal implementation. For many years, REST has been the default approach for designing web APIs. It is simple, familiar, and supported by almost every modern technology platform. GraphQL introduced a different model, giving clients more control over the data they request. The decision between GraphQL and REST should not be based on which technology is newer. It should be based on the structure of the data, client requirements, performance expectations, operational complexity, and long-term maintainability. This article explains the context behind both approaches, compares their architectural characteristics, and identifies the situations where each one is most effective. What Is a REST API? REST, or Representational State Transfer, is an architectural style for building network-based applications. ...
