coin

Coin is a fictional banking system created to spend my time on something productive.

This repository provides a small API for user and transaction management. It includes a minimal SQLite-backed server and simple visualization endpoints.

Quick start

1. Install dependencies:

npm install

2. Run in development mode (auto-reload):

npm run dev

3. Run in production mode:

npm start
# or
npm run start:prod

API docs

OpenAPI and a human-readable API summary are available at /docs once the server is running. For example: http://localhost:3000/docs/API.md.

Notes

• The server includes basic production hardening (Helmet, CORS, rate limiting, request logging).
• All JSON responses follow a universal format: { success: boolean, data?: any, error?: any }.

Contributions are welcome via issues and pull requests.
