GraphQL vs REST: Which is Better for APIs?
In the world of web development, communication between a client (like a web or mobile app) and a server is crucial. Traditional REST APIs have been the go-to solution for many years, but GraphQL is emerging as a powerful alternative that offers more flexibility and efficiency. GraphQL is a query language for API and a server-side runtime engine used for data query and manipulation. It was developed by Facebook, and later made open source, and is now managed by GraphQL foundation hosted by Linux foundation. Many popular public APIs like Facebook, GitHub, Yelp, Shopify, and Google Directions API adopted GraphQL as the default way to access their services.
