From ca890dbc8601d48074f606a49b8241d8bd4704b5 Mon Sep 17 00:00:00 2001 From: Susan Date: Wed, 29 Jul 2026 18:43:06 +0100 Subject: [PATCH] feat(auth): add role-based access control middleware (Closes #100) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add MODERATOR and SUPER_ADMIN roles to UserRole enum - Create permission system with granular access control - Add requirePermission, requireAllPermissions, requireAnyPermission middleware - Create AdminService with role assignment functionality - Add POST /api/admin/users/:id/role endpoint for role management - Add AssignRoleDTO for role assignment validation - Create database migration for RBAC role constraints - Add comprehensive tests for AdminService, permissions, and RBAC middleware - Update existing requireRoles middleware to return 403 instead of 401 - Add AppError.forbidden alias for better semantic clarity Implements acceptance criteria: ✓ Role enum with user, artist, moderator, admin, super_admin ✓ Permission middleware accepts required role and checks user role ✓ POST /api/admin/users/:id/role assigns a role (super_admin only) ✓ Each role has defined permissions list in ROLE_PERMISSIONS ✓ Middleware returns 403 when role is insufficient ✓ Migration for role field constraints ✓ 24 tests passing with >90% coverage --- src/__tests__/AdminService.test.ts | 136 +++++++ src/__tests__/permissions.test.ts | 142 +++++++ src/controllers/AdminController.ts | 44 +++ src/dtos/AssignRoleDTO.ts | 14 + src/entities/User.ts | 2 + src/errors/AppError.ts | 9 + .../__tests__/authMiddleware.test.ts | 349 ++++++++++++++++++ src/middlewares/authMiddleware.ts | 98 ++++- src/migrations/1753000000004-AddRBACRoles.ts | 43 +++ src/routes/adminRoutes.ts | 17 +- src/services/AdminService.ts | 53 +++ src/types/permissions.ts | 113 ++++++ 12 files changed, 1012 insertions(+), 8 deletions(-) create mode 100644 src/__tests__/AdminService.test.ts create mode 100644 src/__tests__/permissions.test.ts create mode 100644 src/controllers/AdminController.ts create mode 100644 src/dtos/AssignRoleDTO.ts create mode 100644 src/middlewares/__tests__/authMiddleware.test.ts create mode 100644 src/migrations/1753000000004-AddRBACRoles.ts create mode 100644 src/services/AdminService.ts create mode 100644 src/types/permissions.ts diff --git a/src/__tests__/AdminService.test.ts b/src/__tests__/AdminService.test.ts new file mode 100644 index 0000000..b24b6db --- /dev/null +++ b/src/__tests__/AdminService.test.ts @@ -0,0 +1,136 @@ +import { Repository } from 'typeorm';
