As we move forward, we'll explore how to install and set up Shadcn in your project, providing you with the foundation to start building amazing web applications.

Getting Started with Shadcn Installation

Now that we've explored what Shadcn is and its capabilities as a powerful UI component library, let's dive into the practical aspects of getting started with Shadcn installation. This section will guide you through the process of setting up Shadcn in your project and using your first component.

1. Installing Shadcn using npm or yarn

To begin your journey with Shadcn, you'll need to install it in your project. You can do this using either npm or yarn, depending on your preference. Here's how to install Shadcn:

Using npm:

npm install @shadcn/ui

Using yarn:

yarn add @shadcn/ui

Once the installation is complete, you're ready to start configuring Shadcn in your project.

2. Configuring Shadcn in your project

After installing Shadcn, you'll need to configure it in your project. This involves setting up the necessary files and dependencies. Here's a step-by-step guide

1. Create a tailwind.config.js file in your project root if you haven't already.
2. Add the following content to your tailwind.config.js:

module.exports = {
  darkMode: ["class"],
  content: [
    './pages/**/*.{ts,tsx}',
    './components/**/*.{ts,tsx}',
    './app/**/*.{ts,tsx}',
    './src/**/*.{ts,tsx}',
    ],
  theme: {
    extend: {},
  },
  plugins: [require("tailwindcss-animate")],
}

Create a globals.css file in your styles directory and add the following:

@tailwind base;
@tailwind components;
@tailwind utilities;

Import the globals.css file in your main application file (e.g., _app.tsx for Next.js).

3. Importing and using your first Shadcn component

Now that Shadcn is installed and configured, let's import and use your first component. We'll use the Button component as an example:

Import the Button component in your desired file:

import { Button } from "@shadcn/ui/button"

Use the Button component in your JSX:

<button variant="outline">Click me</button>

Here's a comparison of some common Button variants you can use:

Variant	Description	Use Case
default	Standard button	General purpose
outline	Button with outline	Secondary actions
ghost	Transparent button	Subtle actions
link	Button that looks like a link	Navigation within tex

By following these steps, you've successfully installed Shadcn, configured it in your project, and used your first component. This sets the foundation for exploring more of Shadcn's core components and building more complex UI elements in your project.

Next, we'll delve deeper into Shadcn's core components, examining their features and how to customize them to fit your specific needs.

Exploring Shadcn's Core Components

Now that we've covered the installation process, let's dive into the heart of Shadcn by exploring its core components. These building blocks are essential for creating stunning and functional user interfaces.

Here's an example of a simple dropdown implementation:

<dropdownmenu>
  <dropdownmenutrigger>Open</dropdownmenutrigger>
  <dropdownmenucontent>
    <dropdownmenuitem>Option 1</dropdownmenuitem>
    <dropdownmenuitem>Option 2</dropdownmenuitem>
    <dropdownmenuitem>Option 3</dropdownmenuitem>
  </dropdownmenucontent>
</dropdownmenu>

2. Modal and Dialog Components

Modals and dialogs are crucial for displaying important information or gathering user input without navigating away from the current page. Shadcn offers a robust set of modal and dialog components that are both customizable and accessible.

To implement a basic modal, use the following code structure:

<dialog>
  <dialogtrigger>Open Modal</dialogtrigger>
  <dialogcontent>
    <dialogheader>
      <dialogtitle>Modal Title</dialogtitle>
      <dialogdescription>Modal content goes here.</dialogdescription>
    </dialogheader>
  </dialogcontent>
</dialog>

3. Button Component: Customization and Variants

The button component in Shadcn is highly versatile and can be customized to fit various design needs. It comes with several pre-defined variants and allows for easy customization.

Button variants include:

• Default

To use a button with a specific variant, simply add the variant prop:

<button variant="primary">Click me</button>

Customizing buttons is straightforward with Shadcn's theming system. You can modify colors, sizes, and other properties to match your design requirements.

With these core components at your disposal, you're well-equipped to start building sophisticated user interfaces. In the next section, we'll explore advanced Shadcn techniques to take your development skills to the next level.
