Vercel Deployment

Skill Purpose: Cloud platform deployment and hosting configuration patterns

Core Skill Pattern

Objective: Establish reliable deployment pipeline with cloud hosting, environment management, and automated deployment workflows.

Universal Pattern:

Define deployment strategy and hosting requirements
Configure deployment platform and build process
Set up environment management and secrets
Establish deployment automation and CI/CD integration
Create monitoring and performance optimization procedures

Key Decisions (Project-Specific):

Deployment platform selection and hosting tier
Build optimization and caching strategies
Environment management and security procedures
Automation level and deployment triggers
Monitoring and performance requirements

Project-Specific Implementation Notes

Customize per project:

Platform selection based on scalability and cost requirements
Build optimization based on performance needs
Environment complexity based on deployment stages
Automation level based on team workflow and release cadence
Monitoring depth based on application criticality

Example Implementation (Vercel with Next.js Pattern)

Note: This is an example pattern using Vercel. Adapt deployment platform and configuration based on your specific project requirements and hosting needs.

Prerequisites (Example)

Project initialized
Deployment platform selected
Build process tested and working

Example: Vercel Cloud Platform Implementation

Framework-Specific Example: This demonstrates the pattern using Vercel with Next.js. Adapt for your deployment platform and framework.

1. Install Vercel CLI

# Install Vercel CLI globally
npm install -g vercel

# Or use npx without global installation
npm install -D vercel

2. Create Vercel Configuration

Create vercel.json:

7. Update Package.json Scripts

Update package.json scripts:

{
  "scripts": {
    "deploy": "node scripts/deploy.js",
    "deploy:prod": "node scripts/deploy.js production",
    "deploy:preview": "node scripts/deploy.js preview",
    "deploy:info": "node scripts/deploy.js info",
    "deploy:rollback": "node scripts/deploy.js rollback",
    "env:create": "node scripts/env-manager.js create",
    "env:validate": "node scripts/env-manager.js validate",
    "env:sync": "node scripts/env-manager.js sync",
    "env:list": "node scripts/env-manager.js list",
    "build:optimized": "./scripts/build-optimized.sh",
    "build:analyze": "ANALYZE=true npm run build",
    "optimize:build": "node scripts/optimize-build.js",

  }
}

8. Create GitHub Actions Workflow

Create .github/workflows/deploy.yml:

name: Deploy to Vercel

on:
  push:
    branches: [main, develop]
  pull_request:
    branches: [main]

jobs:
  deploy-preview:
    runs-on: ubuntu-latest
    if: github.event_name == 'pull_request'
    
    steps:
      - name: Checkout code
        uses: actions/checkout@v3
        
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
          cache: 'npm'
          
      - name: Install dependencies
        run: npm ci
        
      - name: Run tests
        run: npm run test:ci
        
      - name: Build application
        run: npm run build
        
      - name: Deploy to Vercel Preview
        uses: amondnet/vercel-action@v20
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.VERCEL_ORG_ID }}
          vercel-project-id: ${{ secrets.VERCEL_PROJECT_ID }}
          vercel-args: '--meta=githubCommitHash=${{ github.sha }} --meta=githubMessage="${{ github.event.head_commit.message }}"'

  deploy-production:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main' && github.event_name == 'push'
    
    steps:
      - name: Checkout code
        uses: actions/checkout@v3
        
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
          cache: 'npm'
          
      - name: Install dependencies
        run: npm ci
        
      - name: Run quality gates
        run: npm run quality-gates:ci
        
      - name: Build application
        run: npm run build
        
      - name: Deploy to Vercel Production
        uses: amondnet/vercel-action@v20
        with:
          vercel-token: ${{ secrets.VERCEL_TOKEN }}
          vercel-org-id: ${{ secrets.VERCEL_ORG_ID }}
          vercel-project-id: ${{ secrets.VERCEL_PROJECT_ID }}
          vercel-args: '--prod --meta=githubCommitHash=${{ github.sha }} --meta=githubMessage="${{ github.event.head_commit.message }}"'

  "buildCommand": "npm run build:optimized",
  "functions": {
    "app/api/**/*.ts": {
      "maxDuration": 30,
      "memory": 512
    }
  },
  "headers": [
    {
      "source": "/api/(.*)",
      "headers": [
        {
          "key": "Cache-Control",
          "value": "no-store, must-revalidate"
        }
      ]
    }
  ]
}

Configuration Templates

Complete vercel.json

{
  "version": 2,
  "name": "zeus-framework-app",
  "buildCommand": "npm run build",
  "outputDirectory": ".next",
  "framework": "nextjs",
  "regions": ["iad1"],
  "functions": {
    "app/api/**/*.ts": {
      "maxDuration": 30
    }
  },
  "env": {

    "NEXTAUTH_SECRET": "@nextauth-secret"
  },
  "headers": [
    {
      "source": "/(.*)",
      "headers": [
        {
          "key": "X-Frame-Options",
          "value": "DENY"
        }
      ]
    }
  ]
}

Best Practices

Use environment-specific configs - Separate dev/staging/prod
Optimize build size - Bundle analysis and optimization
Monitor deployments - Track performance and errors
Use preview deployments - Test before production
Implement rollback procedures - Quick recovery
Secure environment variables - Never commit secrets
Use CI/CD integration - Automated deployments
Monitor build performance - Optimize build times

Stop Conditions

STOP and report if:

Vercel CLI installation fails
Configuration errors occur
Build process fails
Deployment errors

Expected Outcomes:

Vercel deployment configured
Environment management working
Build optimization applied
Monitoring system active
CI/CD integration working

Verification Checklist

Vercel CLI installed
vercel.json configured
Deployment scripts functional
Environment management working
Build optimization applied
Monitoring system active
GitHub Actions configured
Package.json scripts updated
Rollback procedures defined
Health checks implemented
