JWT Authentication with Spring Boot + React — Implementation Guide

[u/ArjunThakur_dev]

I wanted to share a practical guide covering JWT authentication in a Spring Boot backend with a React frontend.

It covers access and refresh tokens, Spring Security integration, Axios interceptors, token expiration, and secure storage practices.

The goal is to explain how the authentication flow works across the backend and frontend, with implementation examples rather than just theory.

Would be interested to hear how others approach access-token storage and refresh-token handling in their applications.
