GraphQL is a source code for communicating with APIs, which is an alternative to the popular REST. It's a query language that allows retrieval and manipulation of data, providing a common interface between client and server, and allows access to data with fewer resources than REST. Developed by Facebook, it was first used in 2012, but as publicly available code it has been around since 2015. Thanks to its highly intuitive and flexible operation, it provides a good user experience and is becoming increasingly popular in the development community.
GraphQL - a flexible alternative to REST for communicating with APIs
GraphQL is a technology that simplifies work mainly on the frontend side, as it allows developers to execute queries much faster than before. In the case of REST, which is based on rather complex structures that no matter what the client needs at the moment, will get either too little or too much unnecessary information. To eliminate this problem, more endpoints, or endpoints that can be referenced, must be added. This, in turn, makes the whole infrastructure grow unnecessarily, causes problems with its maintenance, as well as with the proper naming of more endpoints. In GraphQL, the client can specify in its requests exactly what data (objects and their attributes) it needs at any given time. Also, it can limit these objects and determine what data it wants to be sent and what data it wants to be skipped. Such great flexibility of this query language makes working with it much faster than with REST. It is thanks to this technology that the entire project can be expanded more easily and the time it takes to implement new functionality into it can be significantly reduced. What's more, GraphQL is independent of various database management systems, so it can handle each developer's individual data and coding.
