This repository contains a basic skeleton for a mobile invoice application with a React Native front end and a Node.js/Express back end.

• Node.js 18+
• npm (comes with Node)

1. Navigate to the backend directory:

   cd backend
   npm install
   npm start

   The backend will start on port 3000.

1. Navigate to the frontend directory:

   cd frontend
   npm install
   npm run start

   The React Native bundler will start. You can run the app using the android or ios scripts depending on your environment.

• frontend contains the React Native application with a simple form to create invoices.
• backend contains an Express server exposing a /api/invoices endpoint that returns invoice data. In a real application you would persist data to a database and generate PDF invoices.

This project aims to provide a clean starting point for further enhancements in UI/UX and functionality.
