Spring Developer Advocate

This book has a doubly difficult job: to introduce both the low-level GraphQL specification and the high-level and very new Spring for GraphQL component model, making it accessible to all, and it does it with aplomb. This is categorically the best treatment of GraphQL for any Java developer today and deserves a place on the bookshelf of anyone that wants to build APIs for the modern web.
