Gin JWT Middleware

Gin JWT Middleware is a JWT authentication middleware for applications built with the Gin web framework in Go. It gives developers ready-to-use handlers for login, logout, token refresh, and protected routes. The middleware supports custom authentication logic, authorization checks, claims, token lookup rules, and response callbacks. It can work with tokens in headers or cookies and includes stronger refresh-token patterns for production use. It also supports Redis-backed refresh token storage, direct token generation, and multi-provider validation strategies. Overall, it is designed to make secure API authentication easier while keeping implementation flexible.
