G1Joshi Vercel
Vercel is the platform for the frontend cloud. In 2025, it has expanded beyond hosting to become a full AI and Storage platform (Vercel Blob/Postgres).
When to Use
- Next.js: The best place to deploy Next.js apps.
- Frontend-First: Deploys from Git, automatic preview URLs for every PR.
- AI Apps: Native integration with Vercel AI SDK for streaming LLM responses.
Quick Start (CLI)
npm i -g vercel
# Deploy (Preview)
vercel
# Deploy (Production)
vercel --prod
Core Concepts
Infrastructure as Code (Implicit)
vercel.json or framework defaults. Minimal config required.
Serverless & Edge Functions
API routes in app/api are deployed as Serverless (Node.js) or Edge (WinterCG) functions automatically.
Storage
Vercel now provides:
- KV: Redis (Upstash)
- Postgres: SQL (Neon)
- Blob: Object Storage (R2)
Best Practices (2025)
Do:
- Use Comments for Preview: Vercel Toolbar allows stakeholders to comment directly on the Preview UI.
- Use Vercel Postgres: For new side projects, the tight integration is unbeatable.
- Use
vercel env pull: Sync production env vars to local.env.
Don't:
- Don't ignore region: Ensure your Database and Function regions match (e.g., both
iad1), otherwise latency kills performance.
