Bank-Managment-system

NovaBank — Full-Stack Bank Management System

A complete, working bank portal: accounts, transfers, cards, bill pay, statements, notifications, and an admin console — with a real Node.js/Express + SQLite backend behind a fast, no-build-step HTML/CSS/JS frontend.

Run it locally

cd backend
npm install
node db/seed.js     # creates demo + admin accounts with sample data
npm start            # starts the server on http://localhost:4000

Then open http://localhost:4000 in your browser. The Express server serves the frontend directly, so there’s nothing else to run.

Requires Node.js 22.5+ (24.x is fine). The database layer uses Node’s built-in node:sqlite module, so there’s no native compiler, Python, or build tools needed — npm install only installs plain JavaScript packages. You’ll see a one-line ExperimentalWarning: SQLite is an experimental feature at startup — that’s expected and harmless.

Demo logins

Role	Email	Password
Customer	demo@novabank.com	Demo@12345
Admin	admin@novabank.com	Admin@12345

Or click “Open an account” on the login screen to register your own.

What’s included

Backend (backend/) — Express + SQLite (better-sqlite3), JWT auth, bcrypt password hashing.

• routes/auth.js — register, login, session
• routes/accounts.js — checking/savings accounts, deposits, withdrawals
• routes/transactions.js — transfers between own or other accounts, full ledger
• routes/cards.js — issue virtual cards, freeze/unfreeze, spending limits
• routes/billpay.js — payees, billers, one-off payments
• routes/profile.js — edit profile, change password
• routes/notifications.js — in-app notifications
• routes/admin.js — bank-wide oversight, freeze customers/accounts

Frontend (frontend/) — plain HTML/CSS/JS (no build step, loads instantly).

• login.html / register.html — split-screen auth screens
• dashboard.html — balance ledger, spending breakdown, recent activity
• accounts.html, transfer.html, cards.html, billpay.html, statements.html (with CSV export), profile.html, admin.html

Notes

• Data lives in backend/db/bank.db (SQLite file), created on first run.
• Change JWT_SECRET in backend/.env before using this anywhere but locally.
• This is a portfolio/demo build — card numbers, CVVs, etc. are generated for realism but are not connected to any real payment network.
