Netflix has open sourced its DGS Framework (Domain Graph Service) GraphQL server framework for Spring Boot. Starting out as a tool internal to the corporation, it has been generously open sourced for the rest of us to enjoy.
Netflix is one of those organizations that have gone beyond REST, embracing GraphQL instead. Rather than exposing a myriad of microservices to UI developers, Netflix opted for a unified API aggregation layer at the edge, powered by GraphQL. Since they also use Spring Boot for their infrastructure, merging was bound to happen.
