GraphQL API with Sinatra web framework

GraphQL has redefined the way we deal with APIs and endpoints. With the client being able to specify the fields it needs, development in the client could in one way be independent of the server changes, if a schema is predefined.

We’ll see how to create a GraphQL server using the Sinatra framework in Ruby. In this example we will be creating the schema for a conference app, where you can add speakers and list them.
