Internationalize Vue Template Strings

Systematically replace all hardcoded strings in Vue component templates with i18n translation keys.

Phase 1: Audit

  1. Read the target Vue component fully
  2. Identify all hardcoded strings in:
    • Template: text within HTML tags (<p>Text</p>, <button>Click me</button>)
    • Template: bare interpolation without $t() ({{ 'hardcoded' }})
    • Script: data() properties containing display strings
  3. Document the count: "Found X hardcoded strings to internationalize"

Do not internationalize: CSS class names, HTML attributes, test IDs, prop values, dynamic content from variables.

Phase 2: Add Translation Keys

  1. Locate the translation file:
    • Within ui-trellis: find the nearest en_US.js file
    • Elsewhere: find the nearest i18n.ts file
  2. Add new keys under an appropriate namespace using camelCase
  3. Provide translations for all supported languages present in the file (at minimum English)
  4. Key naming examples:
    • "Search for a step" → searchForStep
    • "Node Steps" → nodeSteps

Phase 3: Replace in Template and Script

  • Template text: <p>Text</p> → <p>{{ $t('namespace.key') }}</p>
  • Data properties with display strings → move to computed, use this.$t()
// Before
data() {
  return { options: [{ name: 'Node Steps', value: 'step' }] }
}

// After
computed: {
  options() {
    return [{ name: this.$t('message.nodeSteps'), value: 'step' }]
  }
}

Phase 4: Verify

  1. Count remaining hardcoded strings — must be 0
  2. Run verification grep: 
    grep -E '<(p|button|span)>[^{<]*[A-Z][a-z]+ [a-z]+[^}>]*</(p|button|span)>' [file]
  3. Report: "Internationalization complete: 0 hardcoded strings remaining (from X)"
