This project demonstrates how to implement JWT authentication in a Go application using the Gin web framework.
It includes user registration, login with bcrypt password hashing, JWT token generation, and protected routes.
- User Registration (
/register) - User Login with JWT token (
/login) - Protected routes using JWT middleware (
/api/posts) - In-memory storage for demo purposes
- Easy to extend for real-world use cases
- Secure blog APIs where only authenticated users can create posts.
- Mobile or web apps needing stateless authentication.
- Microservices that require lightweight identity validation.
- Role-based access with custom JWT claims.
- Stateless authentication (no server session storage required).
- Scalable and lightweight for modern applications.
- JWT carries identity and expiration in a single token.
- Easy to integrate with mobile apps, SPAs, or third-party services.
