🎨 Theming & Customization

DRY2 components are built with Tailwind CSS and support extensive customization:

<!-- Custom button styling -->
<dry-button 
    variant="primary"
    size="lg"
    class="shadow-xl hover:shadow-2xl transform hover:scale-105">
    Custom Styled Button
</dry-button>

<!-- Button with Font Awesome icon -->
<dry-button 
    variant="primary"
    icon="fas fa-plus">
    Add Item
</dry-button>

<!-- Icon-only button -->
<dry-button 
    variant="outline"
    icon="fas fa-download">
</dry-button>

<!-- Custom avatar colors -->
<avatar-component 
    name="Jane Doe"
    style="--avatar-bg: #8b5cf6; --avatar-text: white;">
</avatar-component>

CSS Custom Properties

Many components support CSS custom properties for deep customization:

:root {
    --dry-primary-color: #6366f1;
    --dry-secondary-color: #64748b;
    --dry-success-color: #10b981;
    --dry-warning-color: #f59e0b;
    --dry-error-color: #ef4444;
    --dry-border-radius: 0.5rem;
    --dry-shadow: 0 4px 6px -1px rgba(0, 0, 0, 0.1);
}

🧪 Testing

DRY2 comes with comprehensive test coverage using Mocha and Chai:

# Run all tests
npm test

# Run tests with coverage
npm run test:coverage

# Run tests in watch mode
npm run test:watch

# Run tests for specific component
npm run test:component button

Writing Tests

Example test for a custom component:

import { expect } from 'chai';
import '../setup.js';

describe('My Custom Component', () => {
    let element;

    beforeEach(() => {
        element = document.createElement('my-component');
        document.body.appendChild(element);
    });

    it('should create element', async () => {
        await waitForComponent(element);
        expect(element).to.exist;
    });

    it('should respond to attribute changes', async () => {
        element.setAttribute('variant', 'primary');
        await waitForComponent(element);
        
        const button = element.querySelector('.button');
        expect(button.className).to.include('bg-blue-600');
    });
});

🔧 API Reference

Creating Custom Components

You can create custom components by extending HTMLElement:

class MyComponent extends HTMLElement {
    static get observedAttributes() {
        return ['variant', 'size', 'disabled'];
    }

    render() {
        return `
            <div class="${this.getComponentClasses()}">
                ${this.renderSlot('default', 'Default content')}
            </div>
        `;
    }

    getComponentClasses() {
        return `component ${this.variant} ${this.size}`;
    }
}

Common Patterns

State Management

// Reactive state
this.setState({ loading: true });

// Listen to state changes automatically triggers re-render

Event Handling

// Emit custom events
this.emit('component:change', { value: newValue });

// Listen to events
element.addEventListener('component:change', (event) => {
    console.log('New value:', event.detail.value);
});

Accessibility

// Built-in accessibility helpers
this.setAttribute('aria-label', 'Button description');
this.setAttribute('role', 'button');
this.setAttribute('tabindex', '0');

🌐 Framework Integration

React

import { useEffect, useRef } from 'react';
import 'dry2-web-components/button';

function MyReactComponent() {
    const buttonRef = useRef();

    useEffect(() => {
        const button = buttonRef.current;
        
        const handleClick = (event) => {
            console.log('Button clicked:', event.detail);
        };

        button.addEventListener('button:click', handleClick);
        return () => button.removeEventListener('button:click', handleClick);
    }, []);

    return (
        <dry-button 
            ref={buttonRef}
            variant="primary"
            size="lg">
            React Button
        </dry-button>
    );
}

Vue

<template>
    <dry-button 
        :variant="variant"
        :size="size"
        @button:click="handleClick">
        Vue Button
    </dry-button>
</template>

<script>
import 'dry2-web-components/button';

export default {
    data() {
        return {
            variant: 'primary',
            size: 'lg'
        };
    },
    methods: {
        handleClick(event) {
            console.log('Button clicked:', event.detail);
        }
    }
};
</script>

Angular

import { Component, ElementRef, ViewChild } from '@angular/core';
import 'dry2-web-components/button';

@Component({
    selector: 'app-button',
    template: `
        <dry-button 
            #buttonElement
            [attr.variant]="variant"
            [attr.size]="size"
            (button:click)="handleClick($event)">
            Angular Button
        </dry-button>
    `
})
export class ButtonComponent {
    @ViewChild('buttonElement') buttonElement!: ElementRef;
    
    variant = 'primary';
    size = 'lg';

    handleClick(event: CustomEvent) {
        console.log('Button clicked:', event.detail);
    }
}

📱 Responsive Design

All components are mobile-first and responsive:

<!-- Responsive button sizes -->
<dry-button 
    size="sm"
    class="md:size-md lg:size-lg">
    Responsive Button
</dry-button>

<!-- Responsive avatar -->
<avatar-component
    size="sm"
    class="md:size-md lg:size-lg"
    name="John Doe">
</avatar-component>
