There are several advantages to using GraphQL APIs:
Flexibility: With GraphQL, clients can request exactly the data they need, and the server will only return that data. This allows for greater flexibility and reduces over-fetching or under-fetching of data.
Strongly typed: GraphQL has a strong type system, which allows for better documentation and easier development, as well as fewer errors in the code.
Reduced number of API calls: With GraphQL, clients can request multiple resources in a single query, which can reduce the number of API calls to the server.
Better performance: Because GraphQL allows clients to request exactly the data they need, the server can be more efficient in fulfilling those requests.
Easy to learn: GraphQL's syntax is simple and easy to learn, even for developers who are new to it.
Open-source: GraphQL is open-source and has a growing ecosystem of tools and libraries to help developers work with it.
