Gin Go Framework

Gin is a high-performance HTTP web framework for Go. It provides fast routing (using a radix tree), middleware support, request binding/validation, and JSON response marshaling. Gin is built on top of Go's standard library net/http, adding convenient abstractions for common REST API tasks. Key features: (1) fast routing with path parameters, (2) middleware chain (authentication, logging, CORS), (3) automatic request binding (JSON, form, query params) and validation, (4) group routing for API versioning (e.g., /api/v1), (5) built-in error handling.
