🔧 Technical Improvements

New Validation Module

// Advanced validation with builder pattern
let email_validator = InputValidator::new("email")
    .required()
    .email();

let password_validator = InputValidator::new("password")
    .required()
    .min_length(8)
    .pattern(r"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).*$".to_string());

Enhanced Input Component

<Input 
    validator=Some(email_validator)
    show_validation=Signal::derive(|| true)
    validation_error=MaybeProp::from("Custom error message")
    // ... other props
/>

Validation Context Support

let mut context = ValidationContext::new();
context.add_validator(email_validator);
context.add_validator(password_validator);

let result = context.validate_all(&form_values);

🎯 Usage Examples

Basic Validation

use leptos_shadcn_input::{Input, InputValidator, validation_builders};

let email_validator = validation_builders::email_validator("email");

view! {
    <Input 
        validator=Some(email_validator)
        show_validation=Signal::derive(|| true)
        placeholder="Enter your email"
    />
}

Custom Validation

let custom_validator = InputValidator::new("username")
    .required()
    .min_length(3)
    .max_length(20)
    .custom(|value| value.starts_with("user_"));

view! {
    <Input 
        validator=Some(custom_validator)
        show_validation=Signal::derive(|| true)
    />
}

Multi-field Validation

let mut context = ValidationContext::new();
context.add_validator(validation_builders::email_validator("email"));
context.add_validator(validation_builders::password_validator("password"));

// Validate all fields at once
let result = context.validate_all(&form_data);
if result.is_valid {
    // Proceed with form submission
}

🧪 Testing

Running Tests

# Run all tests
cargo test --package leptos-shadcn-input

# Run specific test categories
cargo test --package leptos-shadcn-input validation
cargo test --package leptos-shadcn-input tdd

Test Categories

• Basic Functionality: CSS classes, value handling, callbacks
• Validation System: Required fields, email, length, pattern validation
• Enhanced Features: Real-time feedback, error display, performance
• Accessibility: ARIA attributes, keyboard navigation, screen reader support
• Leptos v0.8 Compatibility: Signal handling, attribute system

🔄 Migration Guide

For Existing Users

No migration required! All existing Input component usage continues to work unchanged.

For New Validation Features

Simply add the new validation props to existing Input components:

// Before (still works)
<Input value=value on_change=on_change />

// After (with validation)
<Input 
    value=value 
    on_change=on_change
    validator=Some(validator)
    show_validation=Signal::derive(|| true)
/>
