What is the difference between GraphQL vs REST?

GraphQL is a query language that works on a single endpoint compared to multiple Resources in a REST API. GraphQL has a schema and type system while REST doesn’t enforce any type system. Read more about GraphQL vs REST
What is GraphQL used for?
Plus
GraphQL is used on the client to ask exactly the data required efficiently. GraphQL on the server resolves the query and returns only the data asked and nothing more.
Is GraphQL a database?
Plus
No. GraphQL is just a query language for APIs. It is database agnostic. The GraphQL server can query any database and any APIs.
Is GraphQL replacing REST?
Plus
GraphQL can be considered an alternative to REST, but it doesn't replace REST altogether. In fact GraphQL and REST can co-exist in the stack, where REST APIs are abstracted behind a GraphQL server.
Does GraphQL use HTTP?
Plus
GraphQL API is typically served through an HTTP endpoint. But it is protocol agnostic and can use different protocols for different use cases. For example, websockets are used for GraphQL subscriptions to consume realtime data.
