The original title is "How Enterprise React Apps Handle JWT Token Refresh Automatically"

Short summary

Enterprise React apps use separate Access Tokens (short-lived, for API requests) and Refresh Tokens (long-lived, stored in HttpOnly cookies) to balance security and UX. Axios interceptors automatically attach tokens and refresh on 401 errors; a queueing strategy prevents duplicate refresh calls when multiple requests expire simultaneously.

• •Two-token pattern: short-lived Access Tokens + long-lived Refresh Tokens stored in HttpOnly cookies prevent XSS and infinite session hijacking
• •Axios interceptors centralize auth logic, automatically attaching tokens and refreshing transparently when 401 is received
• •Proper queueing prevents multiple simultaneous refresh requests; React Query remains auth-agnostic, focusing only on data fetching
