Vercel

Vercel Overview¶

Vercel is a cloud platform for frontend developers, focused on providing the best developer experience and optimal website performance. As the creator of Next.js, Vercel provides a complete workflow for modern web applications from development, preview, to production deployment. Through its global edge network, automatic CI/CD, and zero-configuration deployment, Vercel lets developers focus on building products without worrying about infrastructure management.

3. Preview Deployments¶

Collaboration and testing:

Independent Preview per PR: Automatically generates preview URLs
Live Comments: Comment directly on preview pages
Team Collaboration: Share previews with the team
Test Environment: Completely isolated test environments
Rollback: One-click rollback to any version

4. Serverless Functions¶

Backend as a service:

API Routes: Next.js API routes
Edge Middleware: Middleware running at the edge
Auto Scaling: Scales automatically on demand
Zero Operations: No server management required
Multi-Language: Node.js, Go, Python, Ruby

Development Workflow¶

Quick Start¶

# Install Vercel CLI
npm i -g vercel

# Login
vercel login

# Deploy project
vercel

# Deploy to production
vercel --prod

Next.js Project¶

Perfect integration:

# Create Next.js project
npx create-next-app@latest my-app
cd my-app

# Local development
npm run dev

# Connect to Vercel
vercel link

# Deploy
vercel --prod

Environment Variables¶

Managing environment configuration:

# Add environment variable
vercel env add DATABASE_URL

# Pull environment variables
vercel env pull .env.local

Using in Next.js:

// Server-side access
const dbUrl = process.env.DATABASE_URL

// Client-side access (requires NEXT_PUBLIC_ prefix)
const apiUrl = process.env.NEXT_PUBLIC_API_URL

Advanced Features¶

Edge Functions¶

Running code at the edge:

// middleware.ts
import { NextResponse } from 'next/server'
import type { NextRequest } from 'next/server'

export function middleware(request: NextRequest) {
  // Get user geolocation
  const country = request.geo?.country || 'US'

  // Add custom header
  const response = NextResponse.next()
  response.headers.set('x-user-country', country)

  return response
}

export const config = {
  matcher: '/api/:path*'
}

Image Optimization¶

Automatic image optimization:

import Image from 'next/image'

export default function Profile() {
  return (
    <Image
      src="/profile.jpg"
      alt="Profile"
      width={500}
      height={500}
      // Vercel auto-optimization
      priority
    />
  )
}

Incremental Static Regeneration¶

Incremental static regeneration:

// pages/posts/[id].tsx
export async function getStaticProps({ params }) {
  const post = await getPost(params.id)

  return {
    props: { post },
    // ISR: Regenerate every 60 seconds
    revalidate: 60
  }
}

Analytics¶

Performance analytics:

// next.config.js
module.exports = {
  analytics: {
    id: 'your-id',
  },
}

Web3 Application Deployment¶

Deploying a Web3 Frontend¶

Next.js + Wagmi + RainbowKit:

# Create project
npx create-next-app@latest my-web3-app
cd my-web3-app

# Install Web3 dependencies
npm install wagmi viem @rainbow-me/rainbowkit

# Deploy to Vercel
vercel --prod

Environment Variable Configuration¶

# Add RPC URLs
vercel env add NEXT_PUBLIC_ALCHEMY_ID
vercel env add NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID

API Routes¶

Serverless API:

// pages/api/nft/[id].ts
import { NextApiRequest, NextApiResponse } from 'next'

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  const { id } = req.query

  // Fetch NFT metadata
  const metadata = await fetchNFTMetadata(id)

  res.status(200).json(metadata)
}

Performance Optimization¶

1. Caching Strategy¶

// next.config.js
module.exports = {
  async headers() {
    return [
      {
        source: '/static/:path*',
        headers: [
          {
            key: 'Cache-Control',
            value: 'public, max-age=31536000, immutable',
          },
        ],
      },
    ]
  },
}

2. Code Splitting¶

// Dynamic import
import dynamic from 'next/dynamic'

const DynamicComponent = dynamic(() => import('../components/Heavy'), {
  loading: () => <p>Loading...</p>,
  ssr: false // Disable SSR
})

3. Resource Optimization¶

Use Next.js Image component
Enable font optimization
Compress JavaScript and CSS
Leverage CDN caching
Implement code splitting
