GraphQL is a server-side, open-source query language developed by Facebook. It is used for application programming interfaces (APIs) development. It allows users to retrieve nothing more than the required data. GraphQL APIs differenciate themselves from regular REST APIs by their unique endpoint, meaning that the requests are centralized on one single URL on the server. GraphQL offers many advantages compared to traditional REST APIs. The fact that every API calls and requests happen on one single endpoint allows for a great customization of commands, and therefore results in better performance in speed.
