// ToolUp Tuesday - #5

Chris and Matt return for ToolUp Thursday (a scheduling exception) to refactor their Go player decisions API. Having separately studied Golang between sessions, they revisit the codebase with fresh eyes and immediately identify structural improvements — breaking a monolithic single-file approach into proper Go packages with separate folders for controllers, models, and routes. They compare two popular Go HTTP frameworks, Gorilla Mux and Gin, discussing trade-offs between simplicity and feature richness. Matt demonstrates his own Go project using Mux with Azure Container Apps, showcasing Go interfaces, dependency injection patterns, and the tenant service architecture. The conversation covers Go pointers, reference semantics, struct composition, and how Go’s implicit interface implementation differs from C# and .NET. They also explore unit testing and mocking challenges in Go, noting the ecosystem differences from .NET’s more integrated testing story. The session ends with planning to integrate a file-based data store and start connecting the player decisions API with the world event engine.
