📝 Advanced Form Patterns

Deep dive into form architecture with Nuxt UI Pro v4, UAuthForm, custom validation, and field composition patterns.

🧠 Reactive State Architecture

🔧 Core Composables

usePostForm

Manages form state, validation, and submission logic for posts:

Implementation: See app/composables/forms/usePostForm.ts for complete form state management.

Features:

  • ✅ Reactive state management
  • ✅ Zod schema validation with i18n
  • ✅ Computed validation status
  • ✅ State reset/update utilities

🎨 Field Components

Base Pattern

All field components follow this pattern:

Implementation: See field components in app/components/ui/form/ for the complete pattern.

Available Fields

  • Input - Basic text input
  • Password - Password field with toggle
  • Textarea - Multi-line text input
  • Select - Dropdown selection

📏 Validation System

Schema Definition

Forms use Zod schemas with i18n integration:

Implementation: See shared/models/ for complete Zod schemas with i18n integration.

Validation Constants

Implementation: See shared/constants/validation.ts for validation limits and constants.

🌍 Internationalization

Form validation messages support multiple languages:

Implementation: See i18n/locales/*/common.json for validation message translations.

🚀 Usage Example

Implementation: See form usage patterns in components that use the usePostForm composable.

✨ Benefits

  • ✅ Type-safe form state management
  • ✅ Reactive validation with real-time feedback
  • ✅ Internationalized error messages
  • ✅ Reusable components with consistent styling
  • ✅ Accessible form structure with proper labels
