Create a minimal working Vercel example. Use when starting a new Vercel integration, testing your setup, or learning basic Vercel API patterns. Trigger with phrases like "vercel hello world", "vercel example", "vercel quick start", "simple vercel code".

Deploy a minimal project to Vercel with a static page and a serverless API route. Confirms your CLI auth, project structure, and deployment pipeline work end to end.

npm init -y
Create the static landing page:
<!-- public/index.html -->
<!DOCTYPE html>
<html>
<head><title>Hello Vercel</title></head>
<body>
<h1>Hello from Vercel</h1>
<p id="result">Loading...</p>
<script>
fetch('/api/hello')
.then(r => r.json())
.then(d => document.getElementById('result').textContent = d.message);
</script>
</body>
</html>
// api/hello.ts
import type { VercelRequest, VercelResponse } from '@vercel/node';
export default function handler(req: VercelRequest, res: VercelResponse) {
res.status(200).json({
message: 'Hello from Vercel Serverless Function!',
timestamp: new Date().toISOString(),
region: process.env.VERCEL_REGION || 'local',
});
}
Install the types:
npm install --save-dev @vercel/node typescript
{
"rewrites": [
{ "source": "/api/(.*)", "destination": "/api/$1" }
],
"headers": [
{
"source": "/api/(.*)",
"headers": [
{ "key": "Cache-Control", "value": "s-maxage=0, stale-while-revalidate" }
