GraphQL is an open-source query language developed by Facebook. This language provides an efficient way to design, create, and use APIs, and GraphQL is essentially an alternative to REST.
It is a query language for Application Programmable Interfaces (API), which basically means that you can access data and request specific actions with GraphQL.
GraphQL has many features such as the following:
- You write the data you like and get exactly the data you want. You do not need to fetch too much information as is usual in REST.
- GraphQL gives developers a single endpoint and you don‘t need a version 2 or version 3 for the same API.
- GraphQL has "strongly-typed" and can be used to create a valid query within the GraphQL system before execution.
- GraphQL helps build powerful APIs
