Shadcn components for React are now the default choice for developers and startups who want full ownership of their UI code, clean Tailwind-first styling, and accessibility that actually works out of the box. If you’re evaluating this toolkit for your projects in 2026 — or fighting bloated library version conflicts — this guide covers everything you need to know.

At YAAM Web Solutions, we’ve adopted Shadcn as the default UI foundation for every new React and Next.js project we build. This guide distills our hands-on experience into a practical, honest breakdown of 30+ UI components — covering how to install them, customize them, and get the most out of them in production.

What Are Shadcn Components for React?

Shadcn components for React are a collection of re-usable UI building blocks — but not in the traditional sense. You don’t install Shadcn as an npm package. Instead, you use the CLI to copy each component’s source code directly into your project. That single design decision changes everything about how you work with React UI components.

Every piece in this library is built on top of Radix UI primitives, which handle complex accessibility behaviour: keyboard navigation, focus management, ARIA attributes, and screen reader support. On top of those primitives, Tailwind CSS handles the visual styling. The result is a component that is both logically solid and visually flexible.

The Philosophy of Owning Your UI Code

Most UI libraries are black boxes. You get a <Modal />, it works, and the moment you need to change underlying behaviour you hit a wall. Shadcn eliminates that wall entirely. Each component lives in your components/ui/ folder — you can read it, modify it, test it, and version-control it. There’s nothing to update, no peer dependency conflicts, and no stylesheet injected at runtime.

Why Shadcn UI Is the Top Choice Among Developers

There are dozens of React UI options available. Here’s what makes Shadcn components for React the ones developers actually stick with — and keep using across every project.

Installing Shadcn Components for React Using the CLI

The CLI is one of the best developer experiences in the React ecosystem. Here’s the complete flow — from a blank project to a working, customised component.

Step 1 — Scaffold the Project

# Create Next.js with TypeScript, Tailwind, App Router
npx create-next-app@latest my-app \
  --typescript --tailwind --eslint --app \
  --src-dir --import-alias "@/*"
cd my-app

Step 2 — Initialise Shadcn

# Creates components.json and lib/utils.ts
npx shadcn@latest init

Step 3 — Add Components

# npm — add multiple components at once
npx shadcn@latest add button card dialog tabs accordion

# pnpm
pnpm dlx shadcn@latest add button card

# yarn
yarn dlx shadcn@latest add button card

# bun
bunx --bun shadcn@latest add button card

# React 19 — add legacy peer deps flag
npx shadcn@latest add button --legacy-peer-deps

Step 4 — Use the Button Component

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

export default function MyPage() {
  return (
    <div className="flex gap-3 flex-wrap">
      <Button>Default</Button>
      <Button variant="outline">Outline</Button>
      <Button variant="destructive">Delete</Button>
      <Button size="sm" variant="ghost">Small Ghost</Button>
    </div>
  )
}

Form with react-hook-form + Zod

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

const schema = z.object({
  email: z.string().email("Please enter a valid email"),
})

export function EmailForm() {
  const form = useForm({ resolver: zodResolver(schema) })
  return (
    <Form {...form}>
      <FormField name="email"
        render={({ field }) => (
          <FormItem>
            <FormLabel>Email Address</FormLabel>
            <FormControl><Input {...field} /></FormControl>
            <FormMessage />
          </FormItem>
        )}
      />
      <Button type="submit" className="mt-4">Subscribe</Button>
    </Form>
  )
}
