💎 Technical Highlights

Type Safety

Fully typed preference operations:

const preferences: CommunicationPreference = await getPreferences(
  token,
  "customer",
  customerId,
  businessId
);

// Helper functions
if (isOptedOut(preferences)) {
  // Handle opted out
}

if (canReceiveChannel(preferences, "email")) {
  // Can send email
}

if (canReceiveType(preferences, "invoice", "sms")) {
  // Can send invoice via SMS
}

Smart Hooks

// Auto-loading preferences
const { preferences, refetch } = usePreferences("customer", customerId);

// Opt-out mutation
const { optOut, isLoading } = useOptOut();
await optOut("customer", customerId, "Too many emails");

// Restore mutation
const { restore } = useRestorePreferences();
await restore("customer", customerId);

Component Reusability

// Navigate to any entity's preferences
<Button onClick={() => navigate("/main", {
  state: {
    selectedForm: "/forms/CustomerPreferencesPage",
    entityType: "customer", // or "user", "supplier"
    entityId: entity.id
  }
})} />
