Mockup Creation

Create polished, interactive UI mockups and prototypes using NuxtJS 4 (Vue) or Next.js (React) with TypeScript and TailwindCSS v4.

Overview

Rapid creation of production-quality mockups with:

NuxtJS 4 (Vue):

• Vue 3 Composition API with TypeScript
• Vite bundler (built-in)
• Auto-imports for components and composables
• Zero-config TypeScript with auto-generated types
• File-based routing from pages/ directory

Next.js (React):

• React 19 with TypeScript v5.1.0+
• Turbopack bundler (default, faster than Webpack)
• App Router with Server/Client Components
• Built-in TypeScript with zero configuration
• File-based routing from app/ directory

Common Features:

• TailwindCSS v4 with modern tooling
• Component-driven architecture
• Server-side rendering (SSR) or static site generation (SSG)
• Interactive reactivity
• Production-ready optimizations

Quick Start

Option A: NuxtJS 4 (Vue-based)

Option A: NuxtJS 4 (Vue-based)

1. Initialize Project

# Create NuxtJS 4 project (TypeScript enabled by default)
npx nuxi@latest init my-mockup
cd my-mockup
npm install

2. Install and Configure TailwindCSS

Install TailwindCSS v4 with Vite plugin:

npm install -D tailwindcss @tailwindcss/vite

Configure nuxt.config.ts:

// https://nuxt.com/docs/4.x/api/configuration/nuxt-config
import tailwindcss from '@tailwindcss/vite'

export default defineNuxtConfig({
  devtools: { enabled: true },
  
  typescript: {
    strict: true,
    typeCheck: true
  },
  
  // Auto-import components and composables
  components: [
    {
      path: '~/components',
      pathPrefix: false,
    },
  ],
  
  // App configuration
  app: {
    head: {
      charset: 'utf-8',
      viewport: 'width=device-width, initial-scale=1',
      title: 'My Mockup',
      meta: [
        { name: 'description', content: 'My mockup description' }
      ],
    }
  },
  
  // Vite configuration with TailwindCSS v4
  vite: {
    plugins: [
      tailwindcss()
    ],
    css: {
      devSourcemap: true
    }
  }
})

Create CSS file and import TailwindCSS (e.g., assets/css/main.css):

@import "tailwindcss";

Import CSS in app.vue or nuxt.config.ts:

// In nuxt.config.ts, add to the config:
export default defineNuxtConfig({
  css: ['~/assets/css/main.css'],
  // ... rest of config
})

3. Start Development

npm run dev
# Opens http://localhost:3000

Option B: Next.js (React-based)

1. Initialize Project

# Create Next.js project (uses recommended defaults with TypeScript and TailwindCSS)
npx create-next-app@latest my-mockup --yes
cd my-mockup

Or with custom options:

npx create-next-app@latest my-mockup
# Choose: TypeScript: Yes, TailwindCSS: Yes, App Router: Yes

2. Verify TailwindCSS v4 Setup

Next.js includes TailwindCSS by default. To upgrade to v4:

npm install -D tailwindcss@next @tailwindcss/postcss@next

Update tailwind.config.ts:

import type { Config } from 'tailwindcss'

export default {
  content: [
    './app/**/*.{js,ts,jsx,tsx,mdx}',
    './components/**/*.{js,ts,jsx,tsx,mdx}',
  ],
} satisfies Config

Update postcss.config.mjs:

export default {
  plugins: {
    '@tailwindcss/postcss': {},
  },
}

Update app/globals.css:

@import "tailwindcss";

3. Start Development

npm run dev
# Opens http://localhost:3000

Workflow

1. Define Structure

Identify mockup requirements:

• Layout type (single page, dashboard, multi-page)
• Sections needed (header, hero, features, footer, sidebar)
• Responsive breakpoints (mobile, tablet, desktop)
• Interactive elements (forms, modals, dropdowns)

2. Create Component Architecture

NuxtJS (Vue) auto-imports from:

my-mockup/
├── components/
│   ├── layout/        # Header, Footer, Sidebar (auto-imported)
│   ├── ui/            # Button, Card, Modal, Input (auto-imported)
│   └── sections/      # Hero, Features, Testimonials (auto-imported)
├── pages/             # File-based routing (auto-routed)
├── composables/       # Shared logic (auto-imported)
├── layouts/           # Layout templates (default.vue, dashboard.vue)
└── types/             # TypeScript interfaces

Next.js (React) structure:

my-mockup/
├── app/
│   ├── layout.tsx     # Root layout (required)
│   ├── page.tsx       # Home page
│   ├── dashboard/
│   │   └── page.tsx   # /dashboard route
│   └── globals.css    # TailwindCSS imports
├── components/
│   ├── layout/        # Header, Footer, Sidebar
│   ├── ui/            # Button, Card, Modal, Input
│   └── sections/      # Hero, Features, Testimonials
├── lib/               # Utilities and shared logic
└── types/             # TypeScript interfaces

3. Build Components

NuxtJS (Vue) Example: Type-safe Button Component (components/ui/Button.vue)

<script setup lang="ts">
// No need to import 'computed' - auto-imported by Nuxt
interface Props {
  variant?: 'primary' | 'secondary' | 'outline'
  size?: 'sm' | 'md' | 'lg'
}

const props = withDefaults(defineProps<Props>(), {
  variant: 'primary',
  size: 'md'
})

const buttonClasses = computed(() => {
  const variants = {
    primary: 'bg-blue-600 text-white hover:bg-blue-700',
    secondary: 'bg-gray-600 text-white hover:bg-gray-700',
    outline: 'border-2 border-blue-600 text-blue-600 hover:bg-blue-50'
  }
  const sizes = {
    sm: 'px-3 py-1.5 text-sm',
    md: 'px-4 py-2 text-base',
    lg: 'px-6 py-3 text-lg'
  }
  return `font-semibold rounded-lg transition ${variants[props.variant]} ${sizes[props.size]}`
})
</script>

<template>
  <button :class="buttonClasses">
    <slot />
  </button>
</template>

Usage in pages/index.vue:

<template>
  <div>
    <!-- Auto-imported as UiButton from components/ui/Button.vue -->
    <UiButton variant="primary" size="lg">
      Get Started
    </UiButton>
  </div>
</template>

Next.js (React) Example: Type-safe Button Component (components/ui/Button.tsx)

import { ButtonHTMLAttributes } from 'react'

interface ButtonProps extends ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: 'primary' | 'secondary' | 'outline'
  size?: 'sm' | 'md' | 'lg'
  children: React.ReactNode
}

export function Button({ 
  variant = 'primary', 
  size = 'md', 
  children,
  className = '',
  ...props 
}: ButtonProps) {
  const variants = {
    primary: 'bg-blue-600 text-white hover:bg-blue-700',
    secondary: 'bg-gray-600 text-white hover:bg-gray-700',
    outline: 'border-2 border-blue-600 text-blue-600 hover:bg-blue-50'
  }
  
  const sizes = {
    sm: 'px-3 py-1.5 text-sm',
    md: 'px-4 py-2 text-base',
    lg: 'px-6 py-3 text-lg'
  }
  
  const buttonClasses = `font-semibold rounded-lg transition ${variants[variant]} ${sizes[size]} ${className}`
  
  return (
    < = {}>
      {children}
    
  )
}

Usage in app/page.tsx:

import { Button } from '@/components/ui/Button'

export default function Home() {
  return (
    <div>
      <Button variant="primary" size="lg">
        Get Started
      </Button>
    </div>
  )
}

4. Apply Responsive Design

Use TailwindCSS breakpoints:

• sm: (640px), md: (768px), lg: (1024px), xl: (1280px), 2xl: (1536px)

NuxtJS (Vue) Responsive Grid Example:

<template>
  <div class="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
    <!-- Auto-imported as UiCard from components/ui/Card.vue -->
    <UiCard v-for="item in items" :key="item.id" :data="item" />
  </div>
</template>

<script setup lang="ts">
const items = ref([...])
</script>

Next.js (React) Responsive Grid Example:

import { Card } from '@/components/ui/Card'

export default function FeaturesSection() {
  const items = [
    { id: 1, title: 'Feature 1', description: '...' },
    // ...
  ]
  
  return (
    <div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
      {items.map((item) => (
        <Card key={item.id} data={item} />
      ))}
    </div>
  )
}

5. Add Interactivity

NuxtJS (Vue) Composable Pattern (composables/useModal.ts):

// Auto-imported by Nuxt - no need to import 'ref'
export function useModal() {
  const isOpen = ref(false)
  const open = () => { isOpen.value = true }
  const close = () => { isOpen.value = false }
  return { isOpen, open, close }
}

Usage in any Vue component:

<script setup lang="ts">
// Auto-imported - no import statement needed
const { isOpen, open, close } = useModal()
</script>

Next.js (React) Custom Hook Pattern (lib/hooks/useModal.ts):

import { useState } from 'react'

export function useModal() {
  const [isOpen, setIsOpen] = useState(false)
  const open = () => setIsOpen(true)
  const close = () => setIsOpen(false)
  return { isOpen, open, close }
}

Usage in any React component:

'use client' // Mark as Client Component for interactivity

import { useModal } from '@/lib/hooks/useModal'

export default function MyComponent() {
  const { isOpen, open, close } = useModal()
  
  return (
    <div>
      <button onClick={open}>Open Modal</button>
      {isOpen && <Modal onClose={close} />}
    </div>
  )
}

6. Build for Production

NuxtJS:

npm run build      # Build for production (.output/)
npm run preview    # Preview production build
npm run generate   # Generate static site (SSG)

Next.js:

npm run build      # Build for production (.next/)
npm run start      # Start production server (SSR)
# For static export (SSG), add to next.config.js:
# output: 'export'

Common Patterns

Landing Page (NuxtJS)

Create layout (layouts/default.vue):

<template>
  <div class="min-h-screen flex flex-col">
    <LayoutHeader />
    <main class="flex-1">
      <slot />
    </main>
    <LayoutFooter />
  </div>
</template>

Create page (pages/index.vue):

<template>
  <div>
    <SectionsHero />
    <SectionsFeatures />
  </div>
</template>

Landing Page (Next.js)

Create layout (app/layout.tsx):

import { Header } from '@/components/layout/Header'
import { Footer } from '@/components/layout/Footer'
import './globals.css'

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body className="min-h-screen flex flex-col">
        <Header />
        <main className="flex-1">{children}</main>
        <Footer />
      </body>
    </html>
  )
}

Create page (app/page.tsx):

import { Hero } from '@/components/sections/Hero'
import { Features } from '@/components/sections/Features'

export default function Home() {
  return (
    <div>
      <Hero />
      <Features />
    </div>
  )
}

Dashboard Layout (NuxtJS)

Create dashboard layout (layouts/dashboard.vue):

<template>
  <div class="flex h-screen bg-gray-100">
    <LayoutSidebar class="w-64 bg-white shadow-lg" />
    <div class="flex-1 flex flex-col">
      <LayoutTopBar class="bg-white shadow-sm" />
      <main class="flex-1 overflow-y-auto p-6">
        <slot />
      </main>
    </div>
  </div>
</template>

Use in page (pages/dashboard/index.vue):

<script setup lang="ts">
definePageMeta({
  layout: 'dashboard'
})
</script>

<template>
  <div>
    <!-- Dashboard content -->
  </div>
</template>

Dashboard Layout (Next.js)

Create dashboard layout (app/dashboard/layout.tsx):

import { Sidebar } from '@/components/layout/Sidebar'
import { TopBar } from '@/components/layout/TopBar'

export default function DashboardLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <div className="flex h-screen bg-gray-100">
      <Sidebar className="w-64 bg-white shadow-lg" />
      <div className="flex-1 flex flex-col">
        <TopBar className="bg-white shadow-sm" />
        <main className="flex-1 overflow-y-auto p-6">
          {children}
        </main>
      </div>
    </div>
  )
}

Use in page (app/dashboard/page.tsx):

export default function DashboardPage() {
  return (
    <div>
      {/* Dashboard content */}
    </div>
  )
}

Design System

Colors

• Primary: blue-600, Secondary: gray-600
• Success: green-600, Warning: yellow-600, Error: red-600
• Neutral: gray-100 to gray-900

Spacing

Use consistent scale: p-1 (4px), p-2 (8px), p-4 (16px), p-6 (24px), p-8 (32px)

Typography

• Headings: text-4xl, text-3xl, text-2xl, text-xl
• Body: text-base (16px)
• Weights: font-normal, font-medium, font-semibold, font-bold

# Linux/macOS - Vue component
./scripts/create-component.sh ComponentName ui vue

# Linux/macOS - React component
./scripts/create-component.sh ComponentName ui react

# Windows - Vue component
.\scripts\create-component.ps1 -ComponentName ComponentName -Type ui -Framework vue

# Windows - React component
.\scripts\create-component.ps1 -ComponentName ComponentName -Type ui -Framework react

build-deploy.sh / .ps1 - Build and prepare for deployment

# Linux/macOS
./scripts/build-deploy.sh

# Windows
.\scripts\build-deploy.ps1

NuxtJS CLI commands:

npx nuxi add component ComponentName  # Add new component
npx nuxi add page pageName            # Add new page
npx nuxi add layout layoutName        # Add new layout

Next.js CLI commands:

# No built-in CLI for components, use scripts above
# Or manually create files in app/ or components/

Troubleshooting

NuxtJS (Vue)

TailwindCSS v4 not working:

• Restart dev server after nuxt.config.ts changes
• Verify @import "tailwindcss"; in your CSS file
• Ensure @tailwindcss/vite plugin is in vite.plugins array
• Check CSS file is imported in nuxt.config.ts or app.vue
• Run npx nuxi prepare to regenerate types

TypeScript errors:

• Install Volar extension (not Vetur)
• Run npx nuxi prepare to generate types
• Restart TypeScript server in VS Code

Auto-imports not working:

rm -rf .nuxt
npx nuxi prepare
npm run dev

HMR issues:

rm -rf .nuxt node_modules/.cache
npm run dev

Large bundle size:

• Use lazy loading: defineAsyncComponent(() => import('./Component.vue'))
• Analyze with: npx nuxi analyze

Next.js (React)

TailwindCSS not working:

• Check tailwind.config.ts has correct content paths
• Verify @import "tailwindcss"; in app/globals.css
• Restart dev server after config changes
• Clear .next folder: rm -rf .next && npm run dev

TypeScript errors:

• Ensure tsconfig.json is properly configured
• Run npm run build to see full type checking
• Restart TypeScript server in VS Code

Server vs Client Components:

• Use 'use client' directive at top of file for interactive components
• Server Components (default) cannot use hooks or event handlers
• Client Components can use useState, useEffect, onClick, etc.

Build errors:

rm -rf .next node_modules/.cache
npm install
npm run build

Large bundle size:

• Use dynamic imports: const Component = dynamic(() => import('./Component'))
• Analyze with: npm run build (shows bundle sizes)

Best Practices

Common (Both Frameworks)

1. Component Design: Small, single-purpose, reusable
2. TypeScript: Clear interfaces for props and component APIs
3. TailwindCSS: Prefer utilities over custom CSS
4. Responsive: Mobile-first approach
5. Performance: Use SSR/SSG when appropriate, lazy load large components
6. Accessibility: ARIA labels and keyboard navigation
7. Code Organization: Group related components, consistent naming

NuxtJS (Vue) Specific

8. Composables: Extract shared logic (auto-imported)
9. Auto-imports: Leverage Nuxt's auto-import system for components and composables
10. File-based Routing: Use pages/ directory for automatic routing
11. Layouts: Create reusable layouts for consistent UI structure
12. SEO: Use useHead() and useSeoMeta() for meta tags

Next.js (React) Specific

8. Server Components: Default to Server Components, use Client Components only when needed
9. Data Fetching: Use async Server Components for data fetching
10. Metadata API: Use generateMetadata() for dynamic SEO tags
11. Image Optimization: Use Next.js <Image> component for automatic optimization
12. Route Handlers: Use route.ts for API endpoints in app/api/
