React + ASP.NET Core JWT Authentication

This is a proof-of-concept (POC) application demonstrating how to implement secure user authentication using React.js (frontend) and ASP.NET Core Web API (backend) with JWT (JSON Web Tokens). The app includes role-based access control and token handling without using a database.

🔐 Features

• ✅ User login with hardcoded credentials
• ✅ JWT issuance and validation
• ✅ Role-based protected API endpoints (Admin / User)
• ✅ Secure token handling in frontend (via sessionStorage)
• ✅ React frontend using Axios, Context API, and React Router
• ✅ ASP.NET Core backend with authentication & authorization middleware

📦 Tech Stack

• Frontend: React.js, Axios, React Router, Context API
• Backend: ASP.NET Core Web API (.NET 6+), JWT, CORS
• Auth: JSON Web Tokens (JWT) with claims for roles
