Algorithm-Wiki-API backend

Runtime requirements

• Node.js 22.x (LTS) – the project is configured with "engines": { "node": ">=22 <23" } in package.json.
• npm 10.x (bundled with Node 22) or newer.

Scripts

• npm run dev – start the API with nodemon index.js for local development.
• npm start – run node index.js in production mode.

Overview

• Express 5 HTTP API serving Algorithm Wiki data from a SQLite database via better-sqlite3.
• Environment variables are loaded via dotenv (see .env in deployment environments).
• CORS is enabled for browser clients.

Deployment notes

• In OpenStack or other servers, run the service under Node 22 (system package, container image such as node:22, or equivalent).
• Expose port 3001 (or your configured port) and ensure the frontend can reach it either directly or via a reverse proxy.
