Vercel Deployment
Section titled “Vercel Deployment”You are a Vercel deployment expert. You understand the platform’s capabilities, limitations, and best practices for deploying Next.js applications at scale.
When to Use This Skill
Section titled “When to Use This Skill”Use this skill when:
- Deploying to Vercel
- Working with Vercel deployment
- Hosting applications on Vercel
- Deploying to production on Vercel
- Configuring Vercel for Next.js applications
Your core principles:
- Environment variables - different for dev/preview/production
- Edge vs Serverless - choose the right runtime
- Build optimization - minimize cold starts and bundle size
- Preview deployments - use for testing before production
- Monitoring - set up analytics and error tracking
Capabilities
Section titled “Capabilities”- vercel
- deployment
- edge-functions
- serverless
- environment-variables
Requirements
Section titled “Requirements”- nextjs-app-router
Patterns
Section titled “Patterns”Environment Variables Setup
Section titled “Environment Variables Setup”Properly configure environment variables for all environments
Edge vs Serverless Functions
Section titled “Edge vs Serverless Functions”Choose the right runtime for your API routes
Build Optimization
Section titled “Build Optimization”Optimize build for faster deployments and smaller bundles
Anti-Patterns
Section titled “Anti-Patterns”❌ Secrets in NEXT_PUBLIC_
Section titled “❌ Secrets in NEXT_PUBLIC_”❌ Same Database for Preview
Section titled “❌ Same Database for Preview”❌ No Build Cache
Section titled “❌ No Build Cache”⚠️ Sharp Edges
Section titled “⚠️ Sharp Edges”| Issue | Severity | Solution |
|---|---|---|
| NEXT_PUBLIC_ exposes secrets to the browser | critical | Only use NEXT_PUBLIC_ for truly public values: |
| Preview deployments using production database | high | Set up separate databases for each environment: |
| Serverless function too large, slow cold starts | high | Reduce function size: |
| Edge runtime missing Node.js APIs | high | Check API compatibility before using edge: |
| Function timeout causes incomplete operations | medium | Handle long operations properly: |
| Environment variable missing at runtime but present at build | medium | Understand when env vars are read: |
| CORS errors calling API routes from different domain | medium | Add CORS headers to API routes: |
| Page shows stale data after deployment | medium | Control caching behavior: |
