go-grpc-gateway

What problem does it solve?

This Skill addresses the need to make gRPC services accessible via standard HTTP/REST APIs, simplifying integration with frontends and other services that may not natively support gRPC.

Core Features & Use Cases

• HTTP Binding Generation: Automatically adds HTTP annotations to .proto files.
• Gateway Server Creation: Generates a main.go file for a standalone gateway server.
• Cross-Origin Resource Sharing (CORS): Configures CORS for web accessibility.
• Authentication Passthrough: Allows forwarding of authentication headers.
• OpenAPI/Swagger Spec Generation: Creates an OpenAPI specification for documentation and tooling.
• Use Case: You have a Go gRPC microservice for user management, and you need to expose endpoints like GET /users/{id} and POST /users for a web application to consume. This skill automates the setup of the grpc-gateway to achieve this.

Quick Start

Use the go-grpc-gateway skill to add an HTTP gateway to the attached proto file, forwarding the 'Authorization' header and allowing origins from 'http://localhost:3000'.
