## 🔍 **Component Overview**

InviteOneView.vue manages user invitations with the following key features:

### **Core Functionality**
1. **Invitation Management**: Create, view, and delete invitations

## 📋 **Migration Requirements Analysis**

### ✅ **Phase 1: Database Migration** (Estimated: 3-4 minutes)
**Current Legacy Patterns:**
```typescript
// 🔴 Legacy pattern - databaseUtil import
import * as databaseUtil from "../db/databaseUtil";

// 🔴 Legacy pattern - settings retrieval
const settings = await databaseUtil.retrieveSettingsForActiveAccount();

// 🔴 Legacy pattern - direct PlatformServiceFactory usage  
import { PlatformServiceFactory } from "../services/PlatformServiceFactory";
const platformService = PlatformServiceFactory.getInstance();

// 🔴 Legacy pattern - query result mapping
const baseContacts = databaseUtil.mapQueryResultToValues(queryResult);
```

**Required Changes:**
```typescript
// ✅ Modern pattern - PlatformServiceMixin
import { PlatformServiceMixin } from "@/utils/PlatformServiceMixin";
mixins: [PlatformServiceMixin],

// ✅ Modern pattern - mixin methods
const settings = await this.$accountSettings();
const queryResult = await this.$query("SELECT * FROM contacts");
const baseContacts = await this.$getAllContacts();
```

### ✅ **Phase 2: SQL Abstraction** (Estimated: 3-4 minutes)
**Current SQL Patterns:**
```typescript
// 🔴 Raw SQL in addNewContact()
const sql = `INSERT INTO contacts (${columns.join(", ")}) VALUES (${placeholders})`;
await platformService.dbExec(sql, values);
```

**Required Changes:**
```typescript
// ✅ Service method abstraction
await this.$insertContact(contact);
// or use existing helper methods
```

### ✅ **Phase 3: Notification Migration** (Estimated: 4-6 minutes)
**Current Notification Patterns:**
```typescript
// 🔴 Direct $notify usage - 8 different notifications
this.$notify({
  group: "alert",
  type: "success",
  title: "Copied",
  text: "Your clipboard now contains the link for invite " + inviteId,
}, 5000);

// 🔴 Inline confirmation dialog
this.$notify({
  group: "modal", 
  type: "confirm",
  title: "Delete Invite?",
  text: `Are you sure you want to erase the invite for "${notes}"?`,
  onYes: async () => { ... },
}, -1);
```

**Required Changes:**
```typescript
// ✅ Helper system + constants
import { createNotifyHelpers, TIMEOUTS } from "@/utils/notify";
import { 
  NOTIFY_INVITE_LINK_COPIED,
  NOTIFY_INVITE_LOAD_ERROR,
  NOTIFY_INVITE_CREATE_ERROR,
  NOTIFY_INVITE_DELETE_CONFIRM,
  NOTIFY_CONTACT_ADDED,
  createInviteIdCopyMessage,
  createInviteDeleteConfirmation
} from "@/constants/notifications";

// ✅ Usage with helpers
this.notify.success(createInviteIdCopyMessage(inviteId), TIMEOUTS.STANDARD);
this.notify.confirm(createInviteDeleteConfirmation(notes), onYes);
```

### ✅ **Phase 4: Template Streamlining** (Estimated: 2-4 minutes)
**Current Template Patterns:**
```vue
<!-- 🔴 Inline conditional classes -->
<span v-if="!invite.redeemedAt && invite.expiresAt > new Date().toISOString()" 
      class="text-center text-blue-500 cursor-pointer">
<span v-else class="text-center text-slate-500 cursor-pointer">

<!-- 🔴 Inline date calculations -->
{{ invite.expiresAt > new Date().toISOString() }}
```

**Required Changes:**
```typescript
// ✅ Computed properties for cleaner template
computed: {
  activeInviteClass() { return "text-center text-blue-500 cursor-pointer"; },
  inactiveInviteClass() { return "text-center text-slate-500 cursor-pointer"; },
  isInviteActive() { return (invite) => !invite.redeemedAt && invite.expiresAt > new Date().toISOString(); }
}
```

## 🧪 **Testing Strategy**

### **Critical Functionality to Verify:**
1. **Invitation Creation**: Create new invitations with proper expiration
2. **Invitation Deletion**: Delete invitations with confirmation
3. **Contact Addition**: Add redeemed contacts to contact list
4. **Link Copying**: Copy invitation links to clipboard
5. **Error Handling**: Verify all error scenarios display correctly
6. **Data Loading**: Ensure invites and contacts load correctly

### **Edge Cases to Test:**
1. **Empty States**: No invites available
2. **Expired Invites**: Proper handling of expired invitations
3. **Network Errors**: API failure scenarios
4. **Permission Issues**: Missing registration status
