ClaimReportCertificateView.vue Migration Documentation

Migration Start: 2025-07-08 11:25 UTC
Component: ClaimReportCertificateView.vue
Priority: High (Critical User Journey)
Location: src/views/ClaimReportCertificateView.vue

Pre-Migration Analysis

🔍 Current State Assessment

Database Operations

• Legacy Pattern: Uses databaseUtil.retrieveSettingsForActiveAccount()
• Raw SQL: Uses platformService.dbQuery("SELECT * FROM contacts")
• Data Mapping: Uses databaseUtil.mapQueryResultToValues()
• PlatformServiceFactory: Direct usage instead of mixin

Notification Usage

• Direct $notify Calls: 1 instance found
• Notification Type: danger (error handling)
• Message: Error loading claim

Template Complexity

• Simple Template: Minimal template with canvas element
• Canvas Rendering: Complex canvas drawing logic in component
• QR Code Generation: Uses QRCode library for certificate generation

📋 Migration Requirements

1. Database Migration

• Replace databaseUtil.retrieveSettingsForActiveAccount() with PlatformServiceMixin
• Replace raw SQL query with service method
• Replace databaseUtil.mapQueryResultToValues() with proper typing
• Replace PlatformServiceFactory with PlatformServiceMixin

2. SQL Abstraction

• Replace platformService.dbQuery("SELECT * FROM contacts") with $getAllContacts()
• Use proper service methods for all database operations

3. Notification Migration

• Extract notification message to constants
• Replace direct $notify() call with helper method

4. Template Streamlining

• Extract canvas drawing logic to computed properties where possible
• Simplify component methods

Migration Plan

🎯 Step 1: Database Migration

Replace legacy database operations with PlatformServiceMixin methods:

// Before
const settings = await databaseUtil.retrieveSettingsForActiveAccount();
const platformService = PlatformServiceFactory.getInstance();
const dbAllContacts = await platformService.dbQuery("SELECT * FROM contacts");
const allContacts = databaseUtil.mapQueryResultToValues(dbAllContacts);

// After
const settings = await this.$settings();
this.allContacts = await this.$getAllContacts();

🎯 Step 2: Notification Migration

Extract notification message and use helper method:

// Before
this.$notify({
  group: "alert",
  type: "danger",
  title: "Error",
  text: "There was a problem loading the claim.",
});

// After
this.notify.error(NOTIFY_ERROR_LOADING_CLAIM.message, TIMEOUTS.LONG);

🎯 Step 3: Template Optimization

Extract canvas constants and simplify methods:

// Add computed properties for canvas dimensions
get CANVAS_WIDTH() {
  return 1100;
}

get CANVAS_HEIGHT() {
  return 850;
}
