Generating REST APIs from GraphQL Schemas, a Tutorial

Sofa is a Node.js package that bridges the gap between REST and GraphQL by enabling the automatic generation of RESTful APIs from a GraphQL schema, thus allowing developers to provide both API types without maintaining two separate codebases. The package works by taking a GraphQL schema definition and creating Express middleware to provide REST API endpoints, which simplifies the process of offering multiple API styles to customers. By utilizing a standardized schema and resolvers, Sofa facilitates the mapping of GraphQL concepts to REST, making it an efficient solution for developers who wish to cater to diverse API requirements. Through a setup process involving npm, Express, and GraphQL tools, developers can implement a small API server that supports both GraphQL and REST endpoints, demonstrating the functionality through various queries and mutations. This approach allows for a unified API strategy while maintaining the flexibility and functionality of both systems.
