This is a comprehensive session about implementing authentication in our React application.
We started by discussing JWT tokens and how they work for maintaining user sessions.
The user expressed preference for functional components over class components throughout the project.
We encountered a bug in the authentication middleware where tokens were not being validated correctly.
The solution involved adding proper error handling in the middleware and updating the token refresh logic.
We also implemented role-based access control to restrict certain routes based on user permissions.
The user prefers to use TypeScript for all new components and wants consistent error handling patterns.
We fixed several issues with the login form validation and improved the user experience.
The final implementation includes secure token storage, automatic refresh, and proper logout functionality.
