What is the impact of GraphQL on REST APIs?

GraphQL offers a more flexible and efficient way to interact with APIs compared to REST. It allows clients to request only the data they need, reducing over-fetching and under-fetching issues.

Can you explain how GraphQL reduces over-fetching?

Sure! In REST, endpoints return fixed data structures, which can lead to over-fetching when clients receive more data than needed. GraphQL allows clients to specify exactly what fields they want, minimizing unnecessary data transfer.

Are there any downsides to using GraphQL instead of REST?

Yes, while GraphQL provides flexibility, it can introduce complexity in caching and requires more careful planning of the schema. Additionally, it may have a steeper learning curve for developers unfamiliar with it.

How does GraphQL handle versioning compared to REST?

GraphQL typically avoids versioning by allowing clients to request specific fields. This means you can evolve your API without breaking existing clients, as they can continue to request the fields they need.
