This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Geist, a new font family for Vercel.

Deploy on Vercel

The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.

Check out our Next.js deployment documentation for more details.

Visitor counter (/api/seen)

The status-bar visitor counter needs, in the Vercel Production environment only (so preview deployments and vercel env pull never write to the production counter):

• KV_REST_API_URL + KV_REST_API_TOKEN (or UPSTASH_REDIS_REST_URL + UPSTASH_REDIS_REST_TOKEN)
• VISITOR_SALT — a separate secret of at least 32 characters, e.g. openssl rand -hex 32. It is never derived from the Redis token; without it the route answers 503 and the widget shows —.

Recommended: a Vercel Firewall rate-limit rule on /api/seen (e.g. 20 requests/min per IP, deny), since every request costs at least one Upstash command.
