Wrapping and securing REST APIs with GraphQL

This document discusses using GraphQL to wrap and secure REST APIs. It describes problems with REST APIs like multiple endpoints, over-fetching and under-fetching data, and versioning issues. GraphQL solves these problems with a single endpoint that returns flexible data structures. The document then provides steps to implement GraphQL, including using schemas to define queries and mutations, retrieving data from existing services and APIs, adding authentication middleware, and building a GraphQL server with Node.js and Apollo.
