Lumera Node Tracker

Full-stack dApp starter for the Lumera Testnet ecosystem. Includes a backend (Express + Postgres + WebSocket) and a frontend (React + Vite).

Quick start (local)

Prerequisites

• Node.js 18+
• PostgreSQL database (local or managed). Create database lumera and a user with access.
• Optional: Docker

Backend

cd server
# copy .env.example to .env and edit DATABASE_URL
npm install
node server.js

Frontend

cd client
npm install
npm run dev
# open http://localhost:5173

Notes

• WebSocket server runs on the same port as the backend (7777 by default). Set VITE_WS_URL in .env for production.
• To deploy: push to GitHub, connect backend to Render/Heroku (set DATABASE_URL), deploy frontend to Vercel (set VITE_API_URL and VITE_WS_URL).
• Submission: provide the Vercel frontend URL and GitHub repo link.
