🚀 How to Use

Accessing the Pages

Option 1: Direct Navigation (Available Now)

// In your code
navigate("/main", { 
  state: { selectedForm: "/forms/CommunicationsHistoryPage" } 
});

// Or for stats
navigate("/main", { 
  state: { selectedForm: "/forms/CommunicationStatsPage" } 
});

// Or to send
navigate("/main", { 
  state: { selectedForm: "/forms/SendCommunicationPage" } 
});

Option 2: URL Parameters (Available Now)

/main?form=/forms/CommunicationsHistoryPage
/main?form=/forms/CommunicationStatsPage
/main?form=/forms/SendCommunicationPage

Option 3: Menu Integration (Needs Firebase Remote Config)

Add to Firebase Remote Config menu structure (see below)

---

Adding to Menu (Firebase Remote Config)

Update your Firebase Remote Config with:

{
  "sidebar": [
    {
      "name": "sidebar.communications",
      "module": "communications",
      "icon": "mail",
      "order": 25,
      "isActive": true,
      "children": [
        {
          "name": "sidebar.communicationHistory",
          "module": "communications",
          "icon": "history",
          "path": "/forms/CommunicationsHistoryPage",
          "order": 1,
          "isActive": true
        },
        {
          "name": "sidebar.communicationStats",
          "module": "communications",
          "icon": "analytics",
          "path": "/forms/CommunicationStatsPage",
          "order": 2,
          "isActive": true
        },
        {
          "name": "sidebar.sendCommunication",
          "module": "communications",
          "icon": "send",
          "path": "/forms/SendCommunicationPage",
          "order": 3,
          "isActive": true
        }
      ]
    }
  ]
}

Then add i18n keys:

// en.json
{
  "sidebar": {
    "communications": "Communications",
    "communicationHistory": "History",
    "communicationStats": "Statistics",
    "sendCommunication": "Send Message"
  }
}

// es.json
{
  "sidebar": {
    "communications": "Comunicaciones",
    "communicationHistory": "Historial",
    "communicationStats": "Estadísticas",
    "sendCommunication": "Enviar Mensaje"
  }
}

🛠️ Developer Experience

Type Safety

Every. Single. Thing. Is. Typed.

// API calls are type-safe
const comms: PaginatedCommunications = await getCommunications(
  token,
  businessId,
  filters,  // CommunicationFilters
  page,     // number
  limit     // number
);

// Hook results are typed
const {
  communications, // Communication[]
  total,          // number
  isLoading,      // boolean
  error,          // Error | null
} = useCommunications();

// Component props are strict
<CommunicationCard
  communication={comm}  // Must be Communication
  onViewDetails={fn}    // Must accept Communication
  onResend={fn}         // Must accept string
/>

Reusability

Components can be reused anywhere:

// Use the card anywhere
import { CommunicationCard } from "@/components/forms/communications/CommunicationCard";

// Use the hook anywhere
import { useCommunications } from "@/hooks/useCommunications";

// Use the service anywhere
import { getCommunications } from "@/services/communicationsService";

Maintainability

Clear separation of concerns:

• Types - Data structures
• Services - API calls
• Hooks - State management
• Components - UI rendering
• Pages - Route containers
• i18n - Translations

Easy to:

• Add new filters
• Add new channels
• Add new statuses
• Extend functionality
• Fix bugs
• Add tests

// Get communications with filters
const result = await getCommunications(
  token,
  businessId,
  {
    channel: "email",
    status: "delivered",
    dateFrom: "2025-10-01",
    dateTo: "2025-10-26"
  },
  1,  // page
  20  // limit

console.log(result.data); // Communication[]
console.log(result.total); // number

Using the Hook

import { useCommunications } from "@/hooks/useCommunications";

function MyComponent() {
  const {
    communications,
    total,
    isLoading,
    setFilters,
    setPage
  } = useCommunications();

  return (
    <div>
      {communications.map(comm => (
        <CommunicationCard key={comm.id} communication={comm} />
      ))}
    </div>
  );
}

Using the Component

import { CommunicationCard } from "@/components/forms/communications/CommunicationCard";
