Next.js

Install and configure Next.js.

Create project

Start by creating a new Next.js project using create-next-app:

npx create-next-app@latest my-app --typescript --tailwind --eslint

Run the CLI

Run the shadcn-ui init command to setup your project:

npx buidl-cli@latest init

Configure components.json

You will be asked a few questions to configure components.json:

Would you like to use TypeScript (recommended)? no / yes
Which style would you like to use? › Default
Which color would you like to use as base color? › Slate
Where is your global CSS file? › › app/globals.css
Do you want to use CSS variables for colors? › no / yes
Where is your tailwind.config.js located? › tailwind.config.js
Configure the import alias for components: › @/components
Configure the import alias for utils: › @/lib/utils
Are you using React Server Components? › no / yes

Fonts

I use Inter as the default font. Inter is not required. You can replace it with any other font.

Here's how I configure Inter for Next.js:

1. Import the font in the root layout:

import "@/styles/globals.css"
import { Inter as FontSans } from "next/font/google"
 
import { cn } from "../@/lib/utils"
 
export const fontSans = FontSans({
  subsets: ["latin"],
  variable: "--font-sans",
})
 
export default function RootLayout({ children }: RootLayoutProps) {
  return (
    <html lang="en" suppressHydrationWarning>
      <head />
      <body
        className={cn(
          "min-h-screen bg-background font-sans antialiased",
          fontSans.variable
        )}
      >
        ...
      </body>
    </html>
  )
}

2. Configure theme.extend.fontFamily in tailwind.config.js

const { fontFamily } = require("tailwindcss/defaultTheme")
 
/** @type {import('tailwindcss').Config} */
module.exports = {
  darkMode: ["class"],
  content: ["app/**/*.{ts,tsx}", "components/**/*.{ts,tsx}"],
  theme: {
    extend: {
      fontFamily: {
        sans: ["var(--font-sans)", ...fontFamily.sans],
      },
    },
  },
}

App structure

Here's how I structure my Next.js apps. You can use this as a reference:

.
├── app
│   ├── layout.tsx
│   └── page.tsx
├── components
│   ├── ui
│   │   ├── alert-dialog.tsx
│   │   ├── button.tsx
│   │   ├── dropdown-menu.tsx
│   │   └── ...
│   ├── main-nav.tsx
│   ├── page-header.tsx
│   └── ...
├── lib
│   └── utils.ts
├── styles
│   └── globals.css
├── next.config.js
├── package.json
├── postcss.config.js
├── tailwind.config.js
└── tsconfig.json
  • I place the UI components in the components/ui folder.
  • The rest of the components such as <PageHeader /> and <MainNav /> are placed in the components folder.
  • The lib folder contains all the utility functions. I have a utils.ts where I define the cn helper.
  • The styles folder contains the global CSS.

That's it

You can now start adding components to your project.

npx buidl-cli@latest add button

The command above will add the Button component to your project. You can then import it like this:

import { Button } from "@/components/ui/button"
 
export default function Home() {
  return (
    <div>
      <Button>Click me</Button>
    </div>
  )
}
