labp-backend

Small Node.js/Express API prototype used by the LABP-Stack portfolio.

Requires Node.js 18 or newer.

What it does

• GET / returns a basic service health response.
• POST /analyze accepts { "text": "..." }.
• Text containing price returns PRICING.
• Text containing hello or hi returns GREETING.
• Other text returns UNKNOWN.
• Each request receives a UUID and produces a structured console log.
• A Node.js test suite verifies the current API contract.

This is deterministic keyword matching. It does not use an LLM, NLP model, vector database, automation platform, or voice system.

Run locally

npm install
npm start

The service listens on PORT, defaulting to 3000.

Run the tests with:

npm test

curl http://localhost:3000/

curl -X POST http://localhost:3000/analyze \
  -H 'Content-Type: application/json' \
  -d '{"text":"hello"}'

Current limitations

• No authentication or rate limiting
• Permissive CORS configuration
• No persistence
• No model-based intent classification or confidence score
• No deployment configuration or Infrastructure as Code in this repository
• Public Railway URL previously referenced by LABP-Stack is currently unavailable

Status
