Basic Node.js Example

A minimal Express server demonstrating PersonaKit without Next.js.

Setup

cd examples/basic-node
pnpm install

Configure

Create a .env file:

OPENAI_API_KEY=sk-your-api-key-here

Run

pnpm start

Open http://localhost:3000.

Structure

  • index.ts - Express server with chat endpoint
  • agent.ts - Agent configuration
  • knowledge/ - Sample documents for RAG (optional)

How It Works

  1. The Express server exposes a /api/chat endpoint
  2. Requests are converted to Web Request format
  3. PersonaKit's agent handles the request
  4. Responses are streamed back to the client

Enabling RAG

  1. Add markdown files to knowledge/
  2. Uncomment knowledgeBase in agent.ts
  3. Restart the server

Notes

  • This example uses tsx for TypeScript execution
  • Production deployments should use proper build tooling
  • Consider using frameworks like Fastify for better performance
