Administrator Panel for LMS

Development of Admin Panel for LMS

The LMS admin panel is the operational center of the platform. It manages users, courses, cohorts, payments, configuration, and infrastructure. Unlike an instructor account, the admin panel covers the entire platform and requires fine-grained access control.

Roles and Permissions

Multi-level role-based access control (RBAC):

// Permission check middleware
function requirePermission(permission: string) {
  return (req: Request, res: Response, next: NextFunction) => {
    const userPermissions = req.user.role.permissions;
    if (!userPermissions.includes(permission) && !userPermissions.includes('*')) {
      return res.status(403).json({ error: 'Forbidden' });
    }
    next();
  };
}

// Routes with permissions
router.get('/users', requirePermission('users.read'), usersController.list);
router.delete('/users/:id', requirePermission('users.delete'), usersController.delete);
router.get('/finance/transactions', requirePermission('finance.read'), financeController.list);

User Management

User list with filters (role, status, registration date, course) and search. For 100K+ users—cursor-based pagination, not offset.

User card—complete history: courses, transactions, sessions, change log. Actions: change email/password, assign role, block, impersonation (login as user).

Impersonation—critical support function:

// Login as user
app.post('/admin/impersonate/:userId', requirePermission('users.impersonate'), async (req, res) => {
  const targetUser = await db.users.findByPk(req.params.userId);

  // Save original user in session
  req.session.impersonatorId = req.user.id;
  req.session.userId = targetUser.id;

  // Log action
  await auditLog.create({
    action: 'impersonate',
    actorId: req.user.id,
    targetId: targetUser.id,
    ip: req.ip,
  });

  res.redirect('/dashboard');
});

Course Management

• List all courses with filters (status, category, instructor)
• Quick status change: draft → published → archive
• Course statistics: enrollments, progress, revenue, retention
• Cohort management: creation, bulk student enrollment
• Course cloning for new cohorts

Finance Section

interface TransactionListFilters {
  dateFrom?: Date;
  dateTo?: Date;
  status?: 'succeeded' | 'pending' | 'failed' | 'refunded';
  paymentMethod?: string;
  userId?: string;
  courseId?: string;
  minAmount?: number;
}

Functions:

• Transaction list with CSV/Excel export
• Payment refund (Stripe Refund API) with reason
• Promo codes: create, restrictions (course, expiry, usage count, % discount)
• MRR/ARR charts, LTV by cohort

Platform Analytics

-- Dashboard metrics for period
SELECT
  COUNT(DISTINCT e.student_id) FILTER (WHERE e.created_at >= $1) AS new_enrollments,
  COUNT(DISTINCT e.student_id) FILTER (WHERE cp.last_activity_at >= NOW() - INTERVAL '7 days') AS dau_7d,
  COUNT(DISTINCT c.id) FILTER (WHERE c.completed_at >= $1) AS completions,
  SUM(t.amount) FILTER (WHERE t.created_at >= $1 AND t.status = 'succeeded') AS revenue
FROM enrollments e
LEFT JOIN course_progress cp ON cp.student_id = e.student_id
LEFT JOIN transactions t ON t.user_id = e.student_id;

Grafana or built-in chart components (Recharts/Chart.js): MAU, new registrations, revenue, % course completion.

Platform Configuration

Settings via admin panel without deployment:

• Email templates (Twig/Handlebars editor with preview)
• Notification settings (which types enabled by default)
• Payment system settings (Stripe/PayPal keys)
• SEO meta tags for course pages
• Feature flags (enable/disable features for % of users)

Audit Log

Every admin action is logged:

CREATE TABLE audit_log (
  id          UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  actor_id    UUID REFERENCES users(id),
  action      VARCHAR(200) NOT NULL,  -- 'user.delete', 'course.publish'
  entity_type VARCHAR(100),
  entity_id   UUID,
  old_value   JSONB,
  new_value   JSONB,
  ip_address  INET,
  user_agent  TEXT,
  created_at  TIMESTAMPTZ DEFAULT NOW()
);
CREATE INDEX ON audit_log (actor_id, created_at DESC);
CREATE INDEX ON audit_log (entity_type, entity_id);

UI Framework for Admin Panel

Three options:

• React Admin—ready framework for CRUD interfaces. Fast start, limited customization.
• Tremor / shadcn/ui—component library for custom admin.
• Refine—headless framework, full UI control with ready CRUD logic.

Timeline

Basic admin panel: users, courses, transactions, analytics dashboard—2–3 weeks. Advanced features: impersonation, audit log, feature flags, email editor—another 1–2 weeks.
