  Getting Started
  Let's embark on a hands-on journey to understand how to set up and utilize Shadcn/UI in your React project.
- Project Setup
Create a New React Project: If you don't have an existing project, create a new one using Create React App:

  npx create-react-app my-shadcn-ui-app

Install Shadcn/UI: Navigate into your project directory and install the package using npm or yarn:

  npm install @shadcn/ui

2. Import Components

Now, let's import a component from Shadcn/UI and use it in your React component:

import { Button } from '@shadcn/ui';

function App() {
  return (
   <div>
    <button>
     Click Me
    </button>
   </div>
   );
}

export default App;

3. Explore the Component Library

Shadcn/UI provides a comprehensive collection of components for different UI elements. You can explore these components in the official documentation:

https://ui.shadcn.com/docs/getting-started

The documentation provides detailed information on each component's usage, customization options, and available props.

Examples

Let's dive into some practical examples of how to utilize Shadcn/UI components in your React application:

1. Basic Button

import { Button } from '@shadcn/ui';

function App() {
  return (
   <div>
    <button>
     Click Me
    </button>
   </div>
   );
}

export default App;

This simple example demonstrates how to use the Button component.

2. Input with Error Handling

import { Input, Label, FormError } from '@shadcn/ui';

function App() {
  const [email, setEmail] = useState('');
  const [error, setError] = useState(null);

  const handleChange = (event) =&gt; {
    setEmail(event.target.value);
  };

  const handleSubmit = (event) =&gt; {
    event.preventDefault();

    // Validate email
    if (!isValidEmail(email)) {
      setError('Please enter a valid email address.');
      return;
    }

    // Handle successful submission
    setError(null);
    // ...
  };

  return (
   <form onsubmit="{handleSubmit}">
    <label htmlfor="email">
     Email:
    </label>
    <input id="email" onchange="{handleChange}" type="email" value="{email}"/>
    {error &amp;&amp;
    <formerror>
     {error}
    </formerror>
    }
    <button type="submit">
     Submit
    </button>
   </form>
   );
}

export default App;

This example showcases how to use the Input and Label components, as well as the FormError component for validation feedback.

3. Modal Dialog

import { Modal, Button, useModal } from '@shadcn/ui';

function App() {
  const { isOpen, open, close } = useModal();

  return (
   <div>
    <button onclick="{open}">
     Open Modal
    </button>
    <modal onclose="{close}" open="{isOpen}">
     <modal.header>
      Modal Title
     </modal.header>
     <modal.body>
      <p>
       This is the content of the modal.
      </p>
     </modal.body>
     <modal.footer>
      <button onclick="{close}">
       Close
      </button>
     </modal.footer>
    </modal>
   </div>
   );
}

export default App;

This example demonstrates the usage of the Modal component with its associated useModal hook for managing the modal's state.

Customization

Shadcn/UI embraces Tailwind CSS's utility classes, allowing for deep customization of component styles. You can customize components using Tailwind classes directly within your React components.

import { Button } from '@shadcn/ui';

function App() {
  return (
   <div>
    <button classname="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
     Click Me
    </button>
   </div>
   );
}

export default App;

In this example, we've added Tailwind classes to the Button component to change its background color, hover effect, text color, font weight, padding, and border-radius.

Accessibility

Accessibility is a core principle of Shadcn/UI. Components are built with ARIA attributes and semantic HTML elements to ensure a good user experience for everyone, regardless of their abilities.

Conclusion

Shadcn/UI provides a robust and efficient way to build modern and consistent UIs in your React applications. By embracing utility-first CSS and offering a wide range of pre-built components, Shadcn/UI streamlines development, empowers customization, and prioritizes accessibility.
