💎 Technical Highlights​

Type Safety​

Every template operation is fully typed:

const template: CommunicationTemplate = await createTemplate(token, {
  name: "My Template",
  code: "my_template",
  channel: "email", // Typed enum
  type: "invoice",   // Typed enum
  body: "Hello {{name}}",
  subject: "Invoice",
  isActive: true
});

Smart Hooks​

// Auto-loading with filters
const {
  templates,      // CommunicationTemplate[]
  total,          // number
  isLoading,      // boolean
  setFilters,     // (filters: TemplateFilters) => void
  refetch        // () => void
} = useTemplates({
  channel: "email",
  isActive: true
});

// Preview with variables
const { generatePreview, preview, isLoading } = usePreviewTemplate();
await generatePreview(templateId, { invoiceNumber: "INV-001" });

Component Reusability​

// Use anywhere
import { TemplateCard } from "@/components/forms/communication-templates/TemplateCard";

<TemplateCard
  template={myTemplate}
  onView={handleView}
  onEdit={handleEdit}
  onDuplicate={handleDuplicate}
  onDelete={handleDelete}
/>
