Getting Started

Prerequisites

• Node.js (v18 or newer recommended)
• npm or yarn

Installation

1. Open a terminal in the frontend directory:

   cd frontend

2. Install dependencies:

   npm install
   # or
   yarn install

Running the App

Start the development server:

npm run dev
# or
yarn dev

Visit http://localhost:5173 in your browser.

Available Scripts

• npm run dev — Start development server
• npm run build — Build for production
• npm run preview — Preview production build

Customization

• Edit components in src/components/
• Update styles in src/App.css or src/index.css
• Change assets in src/assets/ or public/

Backend Overview

The backend provides RESTful API endpoints for user authentication and account management. It is designed to work seamlessly with the PayByMe frontend.

Features

• User registration (/signup)
• User login (/login)
• Password validation and error handling
• CORS support for frontend-backend communication
• Simple in-memory or file-based user storage (customize as needed)

Backend Setup

1. Open a terminal in the backend directory:

   cd ../backend

2. Install dependencies:

   npm install

3. Start the backend server:

   node server.js

   The backend will run on http://localhost:3000 by default.

Example Backend Functionality

The backend is built with Node.js and Express. It provides /signup and /login endpoints for user authentication, storing user data in a simple file or in-memory array. You can extend it to use a real database and add more features as needed.

Note: This backend is for demo purposes. For production, use hashed passwords, environment variables, and a real database.

Security Improvements

• Password Hashing: User passwords should be securely hashed before storage. Use a library like bcrypt to hash passwords during signup and to verify them during login.
• JWT Authentication: On successful login, the backend should generate a JSON Web Token (JWT) and return it to the client. The frontend can store this token (e.g., in localStorage) and send it with requests to protected endpoints.

Example (Conceptual)

• On signup: Hash the password with bcrypt before saving.
• On login: Compare the provided password with the stored hash using bcrypt.compare.
• On successful login: Generate a JWT (e.g., with jsonwebtoken), send it to the client, and require it for protected routes.

Note: For production, always use environment variables for secrets and never store plain text passwords.
