✅ Invite Users

• Email Input: Enabled for project owners
• Default Role: New users invited as "Reader"
• Real-time Updates: Immediate token refresh and UI updates
• Validation: Email format and duplicate prevention

✅ Remove User Access

• Role Dropdown: Click role chip to see options
• Remove Option: "Remove access" in dropdown menu
• Safety: Owners cannot remove themselves
• Immediate Effect: Real-time permission updates

✅ Smart UI

• Permission Notice: Info message for non-owners
• Loading States: Visual feedback during operations
• Error Handling: Clear error messages
• Role Colors: Visual distinction between roles

Updated Components

ShareDialogComponent - web-ng-m3/src/app/components/share-dialog/share-dialog.component.ts

New Methods:

// Check if current user is project owner
async isCurrentUserProjectOwner(projectId: string): Promise<boolean>

// Invite user to project
async onAddPeople(): Promise<void>

// Remove user from project
async onRemoveUser(member: ProjectMember): Promise<void>

// Check if user can be managed
canManageUser(member: ProjectMember): boolean

// Get role color for chips
getRoleColor(role: number): string

New Properties:

isOwner: boolean = false;          // Current user is project owner
currentUserEmail: string | null;   // Current user's email

RbacService - web-ng-m3/src/app/services/rbac.service.ts

New Methods:

// Check ownership
async isCurrentUserProjectOwner(projectId: string): Promise<boolean>

// Remove user (now properly implemented)
async removeUserFromProject(projectId: string, userEmail: string): Promise<any>

UI Implementation

Role Management

For Non-Owners:

<mat-chip-set class="role-chip">
  <mat-chip [color]="getRoleColor(member.role)" selected>
    {{ member.roleDisplayName }}
  </mat-chip>
</mat-chip-set>

For Owners:

<button mat-button [matMenuTriggerFor]="roleMenu" class="role-button">
  <mat-chip [color]="getRoleColor(member.role)" selected>
    {{ member.roleDisplayName }}
  </mat-chip>
  <mat-icon>arrow_drop_down</mat-icon>
</button>

<mat-menu #roleMenu="matMenu">
  <button mat-menu-item (click)="onRemoveUser(member)">
    <mat-icon color="warn">person_remove</mat-icon>
    <span>Remove access</span>
  </button>
</mat-menu>

Invite Users Section

Input Field:

<mat-form-field [matTooltip]="isOwner ? 'Enter email address to invite user as Reader' : 'Only project owners can invite users'">
  <input matInput 
         [(ngModel)]="newMemberEmail" 
         placeholder="Enter email address"
         type="email"
         [disabled]="!isOwner || loading">
  <button mat-icon-button matSuffix 
          (click)="onAddPeople()" 
          [disabled]="!isOwner || loading || !newMemberEmail.trim()">
    <mat-icon>person_add</mat-icon>
  </button>
</mat-form-field>

Permission Notice:

<div *ngIf="!isOwner" class="permission-notice">
  <mat-icon>info</mat-icon>
  <span>Only project owners can manage access to this project.</span>
</div>

Permission Flow

Invite User Flow:

1. Owner enters email and clicks "Add"
2. Frontend calls RbacService.inviteUserToProject()
3. Backend validates ownership and allowlist
4. Firebase custom claims updated immediately
5. PermissionRefreshService notifies of changes
6. UI refreshes member list and clears form

Remove User Flow:

1. Owner clicks role chip → dropdown appears
2. Owner clicks "Remove access"
3. Frontend calls RbacService.removeUserFromProject()
4. Backend validates ownership and removes permissions
5. Firebase custom claims updated immediately
6. PermissionRefreshService notifies of changes
7. UI refreshes member list

Security Features

• ✅ Self-removal prevention
• ✅ Input validation
• ✅ Loading states prevent double-clicks

Backend Protection:

Testing Scenarios

Invite User Testing:

# 1. As project owner
- Enter valid email → should invite successfully
- Enter existing member email → should show error
- Enter invalid email → should show validation error

# 2. As non-owner
- All controls should be disabled
- Should see permission notice

Remove User Testing:

# 1. As project owner
- Click other user's role chip → should show dropdown
- Click "Remove access" → should remove user
- Try to remove self → should show error

# 2. As non-owner
- Click role chips → should be non-interactive
- No dropdown menus available

Future Enhancements

Phase 2: Role Management

• Add role change options to dropdown
• Support for multiple role types
• Bulk permission operations

Phase 3: Advanced Features

• Invitation expiration
• Email notifications
• Permission templates
• Access request system

Troubleshooting

Common Issues:

User Still Has Access After Removal:

• Check browser console for permission refresh logs
• Try hard refresh (Ctrl+F5)
• Verify Firebase token refresh occurred

Invite Button Disabled:

• Verify current user is project owner
• Check for JavaScript errors
• Ensure email field has valid content

Role Dropdown Not Appearing:

• Verify user is project owner
• Check if clicking on other users (not self)
• Ensure Material Menu module imported

Debug Logs:

[ShareDialog] Current user is project owner: true
[RbacService] Inviting user@example.com to project PROJECT-123 with role 1
[PermissionRefreshService] Permission change detected: invite user@example.com for project PROJECT-123
[ShareDialog] Successfully invited user, reloading members
