In Next.js, shadcn is simply your library of pre-made, attractive components that you paste into your project.
Let me explain it like we're building a house:
Next.js is the house.
Next.js is the structure: the walls, the roads (your pages), the electrical wiring. It's React, but organized to create a truly fast website.shadcn is like the IKEA catalog that comes with the code.
Instead of buying a ready-made button that you can't modify, you do:
Bash
npx shadcn@latest add button
And then, magic happens: Next.js doesn't fetch the button from the internet every time. It creates a real file on your system:
app/components/ui/button.tsx
The button's code is now IN your house. You open it, change the color, resize it. It's yours.
- So, what does this mean in practice?
Before shadcn, you had to write 50 lines of code in your Next.js page for a nice button.
After shadcn, you just do this:
JSX
import { Button } from "@/components/ui/button"
export default function Page() {
return Button Click here /Button
}
And you already have a modern button that supports dark mode, responsive design, and accessibility.
In short, for Next.js:
Next.js = the engine
Tailwind = the paint
shadcn = the designer furniture you can copy to your home with a single command, and repaint.
