When to Use

Setting up a new project with shadcn/ui
Installing or configuring individual components
Building forms with React Hook Form and Zod validation
Creating accessible UI components (buttons, dialogs, dropdowns, sheets)
Customizing component styling with Tailwind CSS
Implementing design systems with shadcn/ui
Building Next.js applications with TypeScript
Creating complex layouts and data displays

Instructions

Initialize Project: Run npx shadcn@latest init to configure shadcn/ui
Install Components: Add components with npx shadcn@latest add <component>
Configure Theme: Customize CSS variables in globals.css for theming
Import Components: Use components from @/components/ui/ directory
Customize as Needed: Modify component code directly in your project
Add Form Validation: Integrate React Hook Form with Zod schemas
Test Accessibility: Verify ARIA attributes and keyboard navigation

Examples

Complete Form with Validation

"use client"

import { zodResolver } from "@hookform/resolvers/zod"
import { useForm } from "react-hook-form"
import { z } from "zod"
import { Button } from "@/components/ui/button"
import { Form, FormControl, FormField, FormItem, FormLabel, FormMessage } from "@/components/ui/form"
import { Input } from "@/components/ui/input"

const formSchema = z.object({
  email: z.string().email("Invalid email"),
  password: z.string().min(8, "Password must be at least 8 characters"),
})

export function LoginForm() {
  const form = useForm<z.infer<typeof formSchema>>({
    resolver: zodResolver(formSchema),
    defaultValues: { email: "", password: "" },
  })

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(console.log)} className="space-y-4">
        <FormField name="email" render={({ field }) => (
          <FormItem>
            <FormLabel>Email</FormLabel>
            <FormControl><Input type="email" {...field} /></FormControl>
            <FormMessage />
          </FormItem>
        )} />
        <Button type="submit">Login</Button>
      </form>
    </Form>
  )
}

Constraints and Warnings

Not an NPM Package: Components are copied to your project; you own the code
Client Components: Most components require "use client" directive
Radix Dependencies: Ensure all @radix-ui packages are installed
Tailwind Required: Components rely on Tailwind CSS utilities
TypeScript: Designed for TypeScript projects; type definitions included
Path Aliases: Configure @ alias in tsconfig.json for imports
Dark Mode: Set up dark mode with CSS variables or class strategy

Quick Start

For new projects, use the automated setup:

# Create Next.js project with shadcn/ui
npx create-next-app@latest my-app --typescript --tailwind --eslint --app
cd my-app
npx shadcn@latest init

# Install essential components
npx shadcn@latest add button input form card dialog select

For existing projects:

# Install dependencies
npm install tailwindcss-animate class-variance-authority clsx tailwind-merge lucide-react

# Initialize shadcn/ui
npx shadcn@latest init

What is shadcn/ui?

shadcn/ui is not a traditional component library or npm package. Instead:

It's a collection of reusable components that you can copy into your project
Components are yours to customize - you own the code
Built with Radix UI primitives for accessibility
Styled with Tailwind CSS utilities
Includes CLI tool for easy component installation

Installation & Setup

Initial Setup

# Initialize shadcn/ui in your project
npx shadcn@latest init

During setup, you'll configure:

TypeScript or JavaScript
Style (Default, New York, etc.)
Base color theme
CSS variables or Tailwind CSS classes
Component installation path

Installing Individual Components

# Install a single component
npx shadcn@latest add button

# Install multiple components
npx shadcn@latest add button input form

# Install all components
npx shadcn@latest add --all

Manual Installation

If you prefer manual setup:

# Install dependencies for a specific component
npm install @radix-ui/react-slot

# Copy component code from ui.shadcn.com
# Place in src/components/ui/

Charts Component

Installation:

npx shadcn@latest add chart

The charts component in shadcn/ui is built on Recharts - providing direct access to all Recharts capabilities with consistent theming and styling.

ChartContainer and ChartConfig

The ChartContainer wraps your Recharts component and accepts a config prop for theming:

import { Bar, BarChart, CartesianGrid, XAxis, YAxis } from "recharts"
import { ChartContainer, ChartTooltipContent } from "@/components/ui/chart"

const chartConfig = {
  desktop: {
    label: "Desktop",
    color: "var(--chart-1)",
  },
  mobile: {
    label: "Mobile",
    color: "var(--chart-2)",
  },
} satisfies import("@/components/ui/chart").ChartConfig

const chartData = [
  { month: "January", desktop: 186, mobile: 80 },
  { month: "February", desktop: 305, mobile: 200 },
  { month: "March", desktop: 237, mobile: 120 },
]

export function BarChartDemo() {
  return (
    <ChartContainer config={chartConfig} className="min-h-[200px] w-full">
      <BarChart data={chartData}>
        <CartesianGrid vertical={false} />
        <XAxis
          dataKey="month"
          tickLine={false}
          axisLine={false}
          tickFormatter={(value) => value.slice(0, 3)}
        />
        <Bar
          dataKey="desktop"
          fill="var(--color-desktop)"
          radius={4}
        />
        <Bar
          dataKey="mobile"
          fill="var(--color-mobile)"
          radius={4}
        />
        <ChartTooltip content={<ChartTooltipContent />} />
      </BarChart>
    </ChartContainer>
  )
}

ChartConfig with Custom Colors

You can define custom colors directly in the configuration:

const chartConfig = {
  visitors: {
    label: "Visitors",
    color: "#2563eb", // Custom hex color
    theme: {
      light: "#2563eb",
      dark: "#60a5fa",
    },
  },
  sales: {
    label: "Sales",
    color: "var(--chart-1)", // CSS variable
    theme: {
      light: "oklch(0.646 0.222 41.116)",
      dark: "oklch(0.696 0.182 281.41)",
    },
  },
} satisfies import("@/components/ui/chart").ChartConfig

CSS Variables for Charts

Add chart color variables to your globals.css:

@layer base {
  :root {
    /* Chart colors */
    --chart-1: oklch(0.646 0.222 41.116);
    --chart-2: oklch(0.6 0.118 184.704);
    --chart-3: oklch(0.546 0.198 38.228);
    --chart-4: oklch(0.596 0.151 343.253);
    --chart-5: oklch(0.546 0.158 49.157);
  }

  .dark {
    --chart-1: oklch(0.488 0.243 264.376);
    --chart-2: oklch(0.696 0.17 162.48);
    --chart-3: oklch(0.698 0.141 24.311);
    --chart-4: oklch(0.676 0.172 171.196);
    --chart-5: oklch(0.578 0.192 302.85);
  }
}

import { ChartContainer, ChartTooltipContent } from "@/components/ui/chart"

const chartConfig = {
  price: {
    label: "Price",
    color: "var(--chart-1)",
  },
} satisfies import("@/components/ui/chart").ChartConfig

const chartData = [
  { month: "January", price: 186 },
  { month: "February", price: 305 },
  { month: "March", price: 237 },

      <AreaChart data={chartData}>
        <XAxis dataKey="month" tickLine={false} axisLine={false} />
        <YAxis tickLine={false} axisLine={false} />
        <Area
          dataKey="desktop"
          fill="var(--color-desktop)"
          stroke="var(--color-desktop)"
          fillOpacity={0.3}
        />
        <Area
          dataKey="mobile"
          fill="var(--color-mobile)"
          stroke="var(--color-mobile)"
          fillOpacity={0.3}
        />
        <ChartTooltip content={<ChartTooltipContent />} />
        <ChartLegend content={<ChartLegendContent />} />
      </AreaChart>
    </ChartContainer>
  )
}

Pie Chart Example

import { Pie, PieChart } from "recharts"
import { ChartContainer, ChartLegend, ChartLegendContent, ChartTooltipContent } from "@/components/ui/chart"

const chartConfig = {
  chrome: { label: "Chrome", color: "var(--chart-1)" },
  safari: { label: "Safari", color: "var(--chart-2)" },
  firefox: { label: "Firefox", color: "var(--chart-3)" },

Customization

Theming with CSS Variables

shadcn/ui uses CSS variables for theming. Configure in globals.css:

@layer base {
  :root {
    --background: 0 0% 100%;
    --foreground: 222.2 84% 4.9%;
    --primary: 222.2 47.4% 11.2%;
    --primary-foreground: 210 40% 98%;
    --secondary: 210 40% 96.1%;
    --secondary-foreground: 222.2 47.4% 11.2%;
    --muted: 210 40% 96.1%;
    --muted-foreground: 215.4 16.3% 46.9%;
    --accent: 210 40% 96.1%;
    --accent-foreground: 222.2 47.4% 11.2%;
    --destructive: 0 84.2% 60.2%;
    --destructive-foreground: 210 40% 98%;
    --border: 214.3 31.8% 91.4%;
    --input: 214.3 31.8% 91.4%;
    --ring: 222.2 84% 4.9%;
    --radius: 0.5rem;
  }

  .dark {
    --background: 222.2 84% 4.9%;
    --foreground: 210 40% 98%;
    --primary: 210 40% 98%;
    --primary-foreground: 222.2 47.4% 11.2%;
    /* ... other dark mode variables */
  }
}

Customizing Components

Since you own the code, customize directly:

// components/ui/button.tsx
import * as React from "react"
import { Slot } from "@radix-ui/react-slot"
import { cva, type VariantProps } from "class-variance-authority"
import { cn } from "@/lib/utils"

const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        destructive: "bg-destructive text-destructive-foreground hover:bg-destructive/90",
        outline: "border border-input bg-background hover:bg-accent",
        // Add custom variant
        custom: "bg-gradient-to-r from-purple-500 to-pink-500 text-white",
      },
      size: {
        default: "h-10 px-4 py-2",
        sm: "h-9 rounded-md px-3",
        lg: "h-11 rounded-md px-8",
        // Add custom size
        xl: "h-14 rounded-md px-10 text-lg",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
)

export interface ButtonProps
  extends React.ButtonHTMLAttributes<HTMLButtonElement>,
    VariantProps<typeof buttonVariants> {
  asChild?: boolean
}

const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant, size, asChild = false, ...props }, ref) => {
    const Comp = asChild ? Slot : "button"
    return (
      <Comp
        className={cn(buttonVariants({ variant, size, className }))}
        ref={ref}
        {...props}
      />
    )
  }
)
Button.displayName = "Button"

export { Button, buttonVariants }

Next.js Integration

App Router Setup

For Next.js 13+ with App Router, ensure components use "use client" directive:

// src/components/ui/button.tsx
"use client"

import * as React from "react"
import { Slot } from "@radix-ui/react-slot"
import { cva, type VariantProps } from "class-variance-authority"
import { cn } from "@/lib/utils"

// ... rest of component

Layout Integration

Add the Toaster to your root layout:

// app/layout.tsx
import { Toaster } from "@/components/ui/toaster"
import "./globals.css"

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body className="min-h-screen bg-background font-sans antialiased">
        {children}
        <Toaster />
      </body>
    </html>
  )
}

Server Components

When using shadcn/ui components in Server Components, wrap them in a Client Component:

// app/dashboard/page.tsx
import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card"
import { ButtonClient } from "@/components/ui/button-client"

export default function DashboardPage() {
  return (
    <div className="container mx-auto p-6">
      <Card>
        <CardHeader>
          <CardTitle>Dashboard</CardTitle>
        </CardHeader>
        <CardContent>
          <ButtonClient>Interactive Button</ButtonClient>
        </CardContent>
      </Card>
    </div>
  )
}

// src/components/ui/button-client.tsx
"use client"

import { Button } from "./button"

export function ButtonClient(props: React.ComponentProps<typeof Button>) {
  return <Button {...props} />
}

Route Handlers with Forms

Create API routes for form submissions:

// app/api/contact/route.ts
import { NextRequest, NextResponse } from "next/server"
import { z } from "zod"

const contactSchema = z.object({
  name: z.string().min(2),
  email: z.string().email(),
  message: z.string().min(10),
})

export async function POST(request: NextRequest) {
  try {
    const body = await request.json()
    const validated = contactSchema.parse(body)

    // Process form data
    console.log("Form submission:", validated)

    return NextResponse.json({ success: true })
  } catch (error) {
    if (error instanceof z.ZodError) {
      return NextResponse.json(
        { errors: error.errors },
        { status: 400 }
      )
    }

    return NextResponse.json(
      { error: "Internal server error" },
      { status: 500 }
    )
  }
}

Form with Server Action

Using Next.js 14+ Server Actions:

// app/contact/page.tsx
"use client"

import { zodResolver } from "@hookform/resolvers/zod"
import { useForm } from "react-hook-form"
import * as z from "zod"
import { Button } from "@/components/ui/button"
import {
  Form,
  FormControl,
  FormField,
  FormItem,
  FormLabel,
  FormMessage,
} from "@/components/ui/form"
import { Input } from "@/components/ui/input"
import { Textarea } from "@/components/ui/textarea"
import { toast } from "@/components/ui/use-toast"

const formSchema = z.object({
  name: z.string().min(2),
  email: z.string().email(),
  message: z.string().min(10),
})

async function onSubmit(values: z.infer<typeof formSchema>) {
  try {
    const response = await fetch("/api/contact", {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify(values),
    })

    if (!response.ok) throw new Error("Failed to submit")

    toast({
      title: "Success!",
      description: "Your message has been sent.",
    })
  } catch (error) {
    toast({
      variant: "destructive",
      title: "Error",
      description: "Failed to send message. Please try again.",
    })
  }
}

export default function ContactPage() {
  const form = useForm<z.infer<typeof formSchema>>({
    resolver: zodResolver(formSchema),
  })

  return (
    <div className="container mx-auto max-w-2xl py-8">
      <Form {...form}>
        <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-6">
          <FormField
            control={form.control}

              </FormItem>
            )}
          />

            control={form.control}
            name="message"
            render={({ field }) => (

                    placeholder="Your message..."
                    className="resize-none"
                    {...field}
                  />
                </FormControl>
                <FormMessage />
              </FormItem>
            )}
          />

          <Button type="submit" className="w-full">
            Send Message
          </Button>
        </form>
      </Form>
    </div>
  )
}

Metadata with shadcn/ui

Using shadcn/ui components in metadata:

// app/layout.tsx
import { Metadata } from "next"

export const metadata: Metadata = {
  title: {
    default: "My App",
    template: "%s | My App",
  },
  description: "Built with shadcn/ui and Next.js",
}

// app/about/page.tsx
import { Metadata } from "next"
import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card"

export const metadata: Metadata = {
  title: "About Us",
  description: "Learn more about our company",
}

export default function AboutPage() {
  return (
    <div className="container mx-auto py-8">
      <Card>
        <CardHeader>
          <CardTitle>About Our Company</CardTitle>
        </CardHeader>
        <CardContent>
          <p>We build amazing products with modern web technologies.</p>
        </CardContent>
      </Card>
    </div>
  )
}

Font Optimization

Optimize fonts with next/font:

// app/layout.tsx
import { Inter } from "next/font/google"
import { Toaster } from "@/components/ui/toaster"
import { cn } from "@/lib/utils"
import "./globals.css"

const inter = Inter({ subsets: ["latin"] })

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body className={cn("min-h-screen bg-background font-sans antialiased", inter.className)}>
        {children}
        <Toaster />
      </body>
    </html>
  )
}

Advanced Patterns

Form with Multiple Fields

const formSchema = z.object({
  username: z.string().min(2).max(50),
  email: z.string().email(),
  bio: z.string().max(160).min(4),
  role: z.enum(["admin", "user", "guest"]),
  notifications: z.boolean().default(false),
})

export function AdvancedForm() {
  const form = useForm<z.infer<typeof formSchema>>({
    resolver: zodResolver(formSchema),
    defaultValues: {
      username: "",
      email: "",
      bio: "",
      role: "user",
      notifications: false,
    },
  })

  function onSubmit(values: z.infer<typeof formSchema>) {
    console.log(values)
  }

  return (
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-8">
        {/* Username field */}
        <FormField
          control={form.control}
          name="username"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Username</FormLabel>
              <FormControl>
                <Input placeholder="johndoe" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />

        {/* Email field */}
        <FormField
          control={form.control}
          name="email"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Email</FormLabel>
              <FormControl>
                <Input type="email" placeholder="john@example.com" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />

        {/* Textarea field */}
        <FormField
          control={form.control}
          name="bio"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Bio</FormLabel>
              <FormControl>
                <Textarea
                  placeholder="Tell us about yourself"
                  className="resize-none"
                  {...field}
                />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />

        {/* Select field */}
        <FormField
          control={form.control}
          name="role"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Role</FormLabel>
              <Select onValueChange={field.onChange} defaultValue={field.value}>
                <FormControl>
                  <SelectTrigger>
                    <SelectValue placeholder="Select a role" />
                  </SelectTrigger>
                </FormControl>
                <SelectContent>
                  <SelectItem value="admin">Admin</SelectItem>
                  <SelectItem value="user">User</SelectItem>
                  <SelectItem value="guest">Guest</SelectItem>
                </SelectContent>
              </Select>
              <FormMessage />
            </FormItem>
          )}
        />

        {/* Checkbox field */}
        <FormField
          control={form.control}
          name="notifications"
          render={({ field }) => (
            <FormItem className="flex flex-row items-start space-x-3 space-y-0">
              <FormControl>
                <Checkbox
                  checked={field.value}
                  onCheckedChange={field.onChange}
                />
              </FormControl>
              <div className="space-y-1 leading-none">
                <FormLabel>Email notifications</FormLabel>
                <FormDescription>
                  Receive emails about your account activity.
                </FormDescription>
              </div>
            </FormItem>
          )}
        />

        <Button type="submit">Submit</Button>
      </form>
    </Form>
  )
}

Best Practices

Accessibility: Components use Radix UI primitives for ARIA compliance
Customization: Modify components directly in your codebase
Type Safety: Use TypeScript for type-safe props and state
Validation: Use Zod schemas for form validation
Styling: Leverage Tailwind utilities and CSS variables
Consistency: Use the same component patterns across your app
Testing: Components are testable with React Testing Library
Performance: Components are optimized and tree-shakeable

Common Component Combinations

Login Form

<Card className="w-[350px]">
  <CardHeader>
    <CardTitle>Login</CardTitle>
    <CardDescription>Enter your credentials to continue</CardDescription>
  </CardHeader>
  <CardContent>
    <Form {...form}>
      <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-4">
        <FormField
          control={form.control}
          name="email"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Email</FormLabel>
              <FormControl>
                <Input type="email" placeholder="you@example.com" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />
        <FormField
          control={form.control}
          name="password"
          render={({ field }) => (
            <FormItem>
              <FormLabel>Password</FormLabel>
              <FormControl>
                <Input type="password" {...field} />
              </FormControl>
              <FormMessage />
            </FormItem>
          )}
        />
        <Button type="submit" className="w-full">Login</Button>
      </form>
    </Form>
  </CardContent>
</Card>
