Comprehensive overview of the runtime architecture and development process

Nuxt 4 Architecture

Nuxt 4 is a Vue.js-based framework that provides a robust architecture for building modern web applications.

  • Universal Vue.js applications (SSR & SPA)
  • File-based routing system
  • Auto-imports for components and composables
  • Server API routes with Nitro server
  • Middleware support for route handling

Tailwind CSS Integration

Tailwind CSS is a utility-first CSS framework that works seamlessly with Nuxt.

  • Utility-first styling approach
  • JIT (Just-In-Time) mode for optimized builds
  • Component-friendly with @apply directive
  • Customizable design system
  • Responsive design utilities

Prisma ORM

Prisma is a next-generation ORM for Node.js and TypeScript.

  • Type-safe database client
  • Database migrations
  • Declarative data model
  • Connection pooling and management
  • Relations and query optimization

Development Process

The typical workflow when working with this stack:

  1. Define data model in Prisma schema
  2. Run migrations to update database
  3. Create API endpoints in server/ directory
  4. Build Vue components with Tailwind styling
  5. Test application in development mode
  6. Deploy to production environment

Example: API Route with Prisma

// server/api/users/[id].get.ts
import { prisma } from '../utils/prisma'

export default defineEventHandler(async (event) => {
  const id = Number(event.context.params?.id)
  
  if (!id) {
    throw createError({
      statusCode: 400,
      statusMessage: 'ID should be an integer',
    })
  }
  
  try {
    const user = await prisma.user.findUnique({
      where: { id },
      include: { posts: true }
    })
    
    if (!user) {
      throw createError({
        statusCode: 404,
        statusMessage: 'User not found',
      })
    }
    
    return user
  } catch (error) {
    console.error('Error fetching user:', error)
    throw createError({
      statusCode: 500,
      statusMessage: 'Internal Server Error',
    })
  }
})

Development Process Steps

1. Project Setup

Initialize a new Nuxt project and install dependencies:

npx nuxi@latest init my-app && cd my-app
npm install -D tailwindcss postcss autoprefixer
npm install @prisma/client
npm install -D prisma

2. Database Configuration

Initialize Prisma and configure your database connection:

npx prisma init
# Edit prisma/schema.prisma to define your data model
npx prisma generate
npx prisma db push

3. Development

Start the development server with hot reload:

npm run dev

4. Building for Production

Build the application for production:

npm run build
