Craft GraphQL APIs in Elixir with Absinthe: Flexible, Robust Services for Queries, Mutations, and Subscriptions

Introduction

Welcome to the world of GraphQL APIs crafted in the Elixir programming language, where fast, scalable, and fault-tolerant systems are paramount. This book, "Craft GraphQL APIs in Elixir with Absinthe: Flexible, Robust Services for Queries, Mutations, and Subscriptions", serves as your comprehensive guide to creating robust GraphQL services using the Elixir ecosystem.

Detailed Summary of the Book

Elixir, a language designed for building scalable and maintainable applications, is a perfect companion to GraphQL, the API query language that empowers developers to build customizable and flexible APIs. This book expertly navigates through using Absinthe, a GraphQL toolkit for Elixir, to harness the power of these technologies. Starting with foundational concepts, it delves into the basics of setting up a GraphQL server using Absinthe, including defining schemas, handling queries, mutations, and subscriptions. As the chapters advance, you'll explore more sophisticated topics such as authentication, authorization, and integrating with various databases. The book is packed with practical examples, well-commented code, and follows a project-based approach that will have you building a feature-rich GraphQL API by the end. This structured journey ensures both novice and seasoned developers in Elixir and GraphQL can follow along, making the integration of GraphQL into Elixir applications not just possible but seamless and rewarding.
