Pulse

Minimal AI chatbot starter using Vite + Vercel AI Gateway.

What this contains

• Simple frontend chat UI (index.html, src/main.js, src/style.css)
• Single serverless endpoint (api/chat.js)
• Streaming responses via AI SDK (streamText)

Setup

1. Install dependencies:

npm install

2. Create .env from .env.example and set your key:

cp .env.example .env

3. Start Vercel local runtime (recommended so /api/* works):

npm run dev:vercel

4. Open the local URL shown by Vercel.

Environment variables

• AI_GATEWAY_API_KEY (required)
• AI_GATEWAY_MODEL (optional, default: openai/gpt-4.1-mini)

Scripts

• npm run dev starts only Vite frontend
• npm run dev:vercel starts Vercel dev server (frontend + API)
• npm run build builds frontend
• npm run preview previews built frontend
