React.js installation guide

Learn how to install Page UI in your React.js app.


Skip the setup and use Shipixen to get a codebase with all components set up.


Step 1

Create a new Next.js app

Start by creating a new React app. The current most popular way to do this is by using Vite. You can use the following command:

npm create vite@latest my-app -- --template react-ts

Step 2

Install dependencies

npm install -D tailwindcss postcss autoprefixer @tailwindcss/forms @tailwindcss/typography tailwindcss-animate class-variance-authority clsx tailwind-merge lucide-react @radix-ui/react-accordion

Step 3

Setup Tailwind CSS

npx tailwindcss init -p

Step 4

Run the Page UI CLI

npx @page-ui/wizard@latest init --template react

Step 5

Configure TypeScript aliases

Add the following code to the tsconfig.json file to resolve paths:

tsconfig.json
{
  "compilerOptions": {
+   "baseUrl": ".",
+   "paths": {
+     "@/*": [
+       "./src/*"
+     ]
+   },

    "target": "ES2020",
    "useDefineForClassFields": true,
    "lib": ["ES2020", "DOM", "DOM.Iterable"],
    "module": "ESNext",
    "skipLibCheck": true,

    /* Bundler mode */
    "moduleResolution": "bundler",
    "allowImportingTsExtensions": true,
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "jsx": "react-jsx",

    /* Linting */
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noFallthroughCasesInSwitch": true,
  },
  "include": ["src"],
  "references": [{ "path": "./tsconfig.node.json" }]
}


Step 6

Configure Vite

Add the following code to the vite.config.ts so your app can resolve paths without error:

npm i -D @types/node
vite.config.ts
+import path from "path"
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react()],
+ resolve: {
+   alias: {
+     "@": path.resolve(__dirname, "./src"),
+   },
+ },
})

Step 7

Configure CSS

Add the below to your index.css file.

app/index.css
@import url('https://fonts.googleapis.com/css?family=Inter:400,500,600,700,800&display=swap');

@tailwind base;
@tailwind components;
@tailwind utilities;

@layer base {
  :root {
    --font-space-default: 'Inter';
    --font-space-display: 'Inter';
    --hard-shadow: 0px 29px 52px 0px rgba(0, 0, 0, 0.4),
      22px 25px 16px 0px rgba(0, 0, 0, 0.2);
    --hard-shadow-left: 0px 29px 52px 0px rgba(0, 0, 0, 0.4),
      -22px 25px 16px 0px rgba(0, 0, 0, 0.2);
    /* If you use Shadcn UI already, you should already have these variables defined */
    --background: 0 0% 100%;
    --foreground: 240 10% 3.9%;

    --border: 240 5.9% 90%;
    --input: 240 5.9% 90%;
    --radius: 0.5rem;
  }

  .dark {
    /* If you use Shadcn UI already, you can skip this block. */
    --background: 20 14.3% 4.1%;
    --foreground: 0 0% 95%;

    --accent: 12 6.5% 15.1%;
    --accent-foreground: 0 0% 98%;
    --destructive: 0 62.8% 30.6%;
    --destructive-foreground: 0 85.7% 97.3%;
    --border: 240 3.7% 15.9%;
    --input: 240 3.7% 15.9%;

  /**

  .container-narrow {
    @apply max-w-4xl;

  }

  .container-ultrawide {
    @apply xl:max-w-7xl;
  }
}


Note: when you create a new React app with Vite, you'll get some sample styles in the index.css file as well as app.css. You can remove all of those safely.


Troubleshooting

Something not quite right? Check out the sample repository for a full working example.

Theming

Get new themes directly from the docs (open any component documentation → select a theme from the dropdown and scroll down to copy to clipboard).

You can also explore themes here.

Alternatively, you can change data/config/color.js manually.

Next steps

Start adding components to your Next.js app.
Go to the component documentation to copy and paste components into your app, or head over to templates or usage examples to see how components are used in a real-world app.
