A basic knowledge of React is a prerequisite for this article. Follow the installation or clone the Starter Template.
Why Shadcn
Its accessible cause its built on top of Radix.
Modern and minimal design for default style , but can be fully customized.
You have the source code in your project.
Its integrated with V0
Installation
The CLI terminal is gonna ask the following questions:
Would you like to start a new Next.js project? … yes
Which style would you like to use? › Default
Which color would you like to use as the base color? › Neutral
Would you like to use CSS variables for theming? …yes
And done! We are al set to start using Shadcn/ui components.
Before continuing let's make sure our Next.js app run correctly. Navigate in our newly created app folder.
And you should see the default page of our project. We can later remove this in the page.tsx.
Components
Shadcn/ui offers a variety of component built with accessibility in mind and minimal, modern and clean design. Check out the full list here.
Lets start simple with a button.
npx shadcn@latest add button
npx shadcn@latest add button
Notice how a new folder components/ui/button.tsx has now appeared in our project. There is where the source code of our component is, and we can fully customizable and change.
Let's import our button in the page.tsx.
import { Button } from "@/components/ui/button"
import { Button } from "@/components/ui/button"
Let's move on something more interactive. Let's add a modal!
npx shadcn@latest add alert-dialog
npx shadcn@latest add alert-dialog
import {
AlertDialog,
AlertDialogAction,
AlertDialogCancel,
AlertDialogContent,
AlertDialogDescription,
AlertDialogFooter,
AlertDialogHeader,
AlertDialogTitle,
AlertDialogTrigger,
} from "@/components/ui/alert-dialog"
import {
AlertDialog,
AlertDialogAction,
AlertDialogCancel,
AlertDialogContent,
AlertDialogDescription,
AlertDialogFooter,
AlertDialogHeader,
AlertDialogTitle,
AlertDialogTrigger,
} from "@/components/ui/alert-dialog"
<AlertDialog>
<AlertDialogTrigger asChild>
<Button>Open modal</Button>
</AlertDialogTrigger>
<AlertDialogContent>
<AlertDialogHeader>
<AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle>
<AlertDialogDescription>
This action cannot be undone. This will permanently delete your
account and remove your data from our servers.
</AlertDialogDescription>
</AlertDialogHeader>
<AlertDialogFooter>
<AlertDialogCancel>Cancel</AlertDialogCancel>
<AlertDialogAction>Continue</AlertDialogAction>
</AlertDialogFooter>
</AlertDialogContent>
</AlertDialog>
<AlertDialog>
<AlertDialogTrigger asChild>
<Button>Open modal</Button>
</AlertDialogTrigger>
<AlertDialogContent>
<AlertDialogHeader>
<AlertDialogTitle>Are you absolutely sure?</AlertDialogTitle>
<AlertDialogDescription>
This action cannot be undone. This will permanently delete your
account and remove your data from our servers.
</AlertDialogDescription>
</AlertDialogHeader>
<AlertDialogFooter>
<AlertDialogCancel>Cancel</AlertDialogCancel>
<AlertDialogAction>Continue</AlertDialogAction>
</AlertDialogFooter>
</AlertDialogContent>
</AlertDialog>
We can add a card, avatar, and cool toast to achieve a result like this:
Dark mode
It wouldn't be a modern UI without a dark mode. So let's add one! Lucky us Shadcn got us covered once again with a comprehensive guide.
Create a theme-provider.tsx
"use client"
import * as React from "react"
import { ThemeProvider as NextThemesProvider } from "next-themes"
import { type ThemeProviderProps } from "next-themes/dist/types"
export function ThemeProvider({ children, ...props }: ThemeProviderProps) {
return <NextThemesProvider {...props}>{children}</NextThemesProvider>
}
"use client"
import * as React from "react"
import { ThemeProvider as NextThemesProvider } from "next-themes"
import { type ThemeProviderProps } from "next-themes/dist/types"
export function ThemeProvider({ children, ...props }: ThemeProviderProps) {
return <NextThemesProvider {...props}>{children}</NextThemesProvider>
}
Add the ThemeProvider to your root layout.
import { ThemeProvider } from "@/components/theme-provider"
export default function RootLayout({ children }: RootLayoutProps) {
return (
<>
<html lang="en" suppressHydrationWarning>
<head />
<body>
<ThemeProvider
attribute="class"
defaultTheme="system"
enableSystem
disableTransitionOnChange
>
{children}
</ThemeProvider>
</body>
</html>
</>
)
}
import { ThemeProvider } from "@/components/theme-provider"
export default function RootLayout({ children }: RootLayoutProps) {
return (
<>
<html lang="en" suppressHydrationWarning>
<head />
<body>
<ThemeProvider
attribute="class"
defaultTheme="system"
enableSystem
disableTransitionOnChange
>
{children}
</ThemeProvider>
</body>
</html>
</>
)
}
Create a toggle component and import it in your page.tsx
"use client"
import * as React from "react"
import { Moon, Sun } from "lucide-react"
import { useTheme } from "next-themes"
import { Button } from "@/components/ui/button"
import {
DropdownMenu,
DropdownMenuContent,
DropdownMenuItem,
DropdownMenuTrigger,
} from "@/components/ui/dropdown-menu"
export function ModeToggle() {
const { setTheme } = useTheme()
return (
<DropdownMenu>
<DropdownMenuTrigger asChild>
<Button variant="outline" size="icon">
<Sun className="h-[1.2rem] w-[1.2rem] rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
<Moon className="absolute h-[1.2rem] w-[1.2rem] rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
<span className="sr-only">Toggle theme</span>
</Button>
</DropdownMenuTrigger>
<DropdownMenuContent align="end">
<DropdownMenuItem onClick={() => setTheme("light")}>
Light
</DropdownMenuItem>
<DropdownMenuItem onClick={() => setTheme("dark")}>
Dark
</DropdownMenuItem>
<DropdownMenuItem onClick={() => setTheme("system")}>
System
</DropdownMenuItem>
</DropdownMenuContent>
</DropdownMenu>
)
}
"use client"
import * as React from "react"
import { Moon, Sun } from "lucide-react"
import { useTheme } from "next-themes"
import { Button } from "@/components/ui/button"
import {
DropdownMenu,
DropdownMenuContent,
DropdownMenuItem,
DropdownMenuTrigger,
} from "@/components/ui/dropdown-menu"
export function ModeToggle() {
const { setTheme } = useTheme()
return (
<DropdownMenu>
<DropdownMenuTrigger asChild>
<Button variant="outline" size="icon">
<Sun className="h-[1.2rem] w-[1.2rem] rotate-0 scale-100 transition-all dark:-rotate-90 dark:scale-0" />
<Moon className="absolute h-[1.2rem] w-[1.2rem] rotate-90 scale-0 transition-all dark:rotate-0 dark:scale-100" />
<span className="sr-only">Toggle theme</span>
</Button>
</DropdownMenuTrigger>
<DropdownMenuContent align="end">
<DropdownMenuItem onClick={() => setTheme("light")}>
Light
</DropdownMenuItem>
<DropdownMenuItem onClick={() => setTheme("dark")}>
Dark
</DropdownMenuItem>
<DropdownMenuItem onClick={() => setTheme("system")}>
System
</DropdownMenuItem>
</DropdownMenuContent>
</DropdownMenu>
)
}
