2. Implementing `UserDetailsService`

Next, create a Service that implements UserDetailsService. The framework will automatically detect this Beam and use it during the login process.

If the user cannot be found, you simply return nil, and the framework will handle the failed authentication safely.

package security

import (
    . "github.com/BeamFoundry/rays-web-security/pkg/core"
    . "github.com/BeamFoundry/rays/pkg/core"
    . "github.com/BeamFoundry/rays/pkg/lang"
)

type DomainUserDetailsService struct {
    Service
    userRepo *UserRepository `@:"Inject"`
}

func (s *DomainUserDetailsService) LoadUserByUsername(username string) UserDetails {
    userOpt := s.userRepo.FindByEmail(username)

    // Return the user if found
    if user, ok := userOpt.Get(); ok {
        return user
    }

    // Return nil if the user does not exist
    return nil
}
