Summary
The optional authentication logic is currently defined inside the server entry file, which mixes authentication concerns with application initialization.
Moving this logic into a dedicated middleware module will improve code organization, readability, and maintainability while preserving the existing behavior.
Proposed Changes
- Create a dedicated middleware file for optional authentication (e.g.,
middleware/optionalAuthenticateUser.js).
- Move the existing JWT verification logic from the server file into the new middleware.
- Export the middleware and import it where needed.
- Preserve the current behavior where authentication is optional and invalid or expired tokens do not block the request.
- Ensure the middleware continues to populate
req.user when a valid token is available.
Benefits
- Better separation of concerns.
- Cleaner server entry file.
- Reusable optional authentication middleware.
- Easier testing and future enhancements.
- No changes to existing API behavior.
