Overview\nThis repository contains the Minimum Viable Product (MVP) for a **Borrow/Lend Tracker** web application. The primary goal is to provide a simple, efficient way for individuals (e.g., users within web marketplaces) to record and track money exchanged between known parties. It maintains a clear ledger (\"sheet\") of who borrowed how much from whom and calculates summaries of net debts and credits per person.\n\nThe frontend is built using **React** with **TypeScript** for type safety, bootstrapped with **Vite** for a fast development experience. **Tailwind CSS** is used for utility-first styling. Global state, including the transaction list and calculated summaries, is managed using **React Context API**. Data persistence relies on interaction with a **conceptual backend API** via **Axios**.\n\n## 📦 Features\n|    | Feature            | Description                                                                                                                                  |\n|----|--------------------|----------------------------------------------------------------------------------------------------------------------------------------------|\n| ⚙️ | **Architecture**   | Component-based React frontend using Vite. Features separation into pages (`pages`), reusable UI elements (`components`), state management (`context`), and API interaction layer (`services`). |\n| 📄 | **Documentation**  | This README provides an overview, setup instructions, usage details, and conceptual API definition. Code includes JSDoc comments where applicable. |\n| 🔗 | **Dependencies**   | Core dependencies include `react`, `react-dom`, `react-router-dom`, `axios`. Dev dependencies include `vite`, `typescript`, `tailwindcss`, `eslint`. |\n| 🧩 | **Modularity**     | Clear separation of concerns: Pages for views, Components for UI elements, Context for global state, Services for API calls.                     |\n| ✨ | **Core Functionality**| Add new transactions (lender, borrower, amount). View a chronological ledger of all transactions. View an aggregated summary of who owes whom. |\n| 🎨 | **Styling**        | Utility-first styling with Tailwind CSS, adhering to a consistent dark theme.                                                                 |\n| 🧭 | **Routing**        | Client-side routing handled by `react-router-dom` for navigation between Ledger, Add Transaction, and Summary pages.                           |\n| 💾 | **State Management**| Global application state (transactions, summaries, loading/error status) managed centrally via React Context API (`TransactionContext`).        |\n| 📡 | **API Interaction**| Uses Axios (`src/services/api.ts`) to communicate with a conceptual backend API for fetching and creating transactions.                     |\n| ✅ | **Validation**     | Includes basic client-side form validation in `TransactionForm.tsx` (required fields, positive amount, lender != borrower).                       |\n\n## 📂 Structure\n```text\n/\n├── public/\n│   └── index.html          # HTML entry point\n├── src/\n│   ├── components/         # Reusable UI components\n│   │   ├── Button.tsx\n│   │   ├── Input.tsx\n│   │   ├── SummaryDisplay.tsx\n│   │   ├── TransactionForm.tsx\n│   │   └── TransactionList.tsx\n│   ├── context/            # React Context for global state\n│   │   └── TransactionContext.tsx\n│   ├── pages/              # Page-level components associated with routes\n│   │   ├── AddTransactionPage.tsx\n│   │   ├── LedgerPage.tsx\n│   │   └── SummaryPage.tsx\n│   ├── services/           # API interaction logic\n│   │   └── api.ts\n│   ├── App.tsx             # Root application component with routing setup\n│   ├── index.css           # Global styles and Tailwind directives\n│   ├── main.tsx            # Application entry point (renders App into DOM)\n│   └── vite-env.d.ts       # Vite environment variable type definitions\n├── .env                    # Environment variables (API base URL) - *DO NOT COMMIT*\n├── .env.example            # Example environment variables file\n├── .eslintrc.cjs           # ESLint configuration (if generated/added)\n├── .gitignore              # Git ignore rules\n├── commands.json           # Descriptions of npm scripts\n├── index.html              # Link to public/index.html (Vite convention)\n├── package.json            # Project dependencies and scripts\n├── postcss.config.js       # PostCSS configuration (for Tailwind/Autoprefixer)\n├── README.md               # This file\n├── startup.sh              # Optional development server startup script\n├── tailwind.config.js      # Tailwind CSS configuration\n├── tsconfig.json           # TypeScript compiler configuration\n└── vite.config.ts          # Vite build tool configuration\n```\n\n## 💻 Installation\n\u003e [!WARNING]\n\u003e ### 🔧 Prerequisites\n\u003e - **Node.js:** LTS version recommended (e.g., v18.x or v20.x). Check with `node -v`.\n\u003e - **npm:** Usually included with Node.js. Check with `npm -v`.\n\u003e - **Git:** For cloning the repository.\n\u003e - **Conceptual Backend API:** This frontend requires a running backend API service that implements the endpoints defined in [API Documentation](#-api-documentation-conceptual-backend). The frontend expects this API to be accessible at the URL specified in the `.env` file.\n\n### 🚀 Setup Instructions\n1.  **Clone the repository:**\n    ```bash\n    git clone https://github.com/coslynx/borrow-lend-ledger.git\n    cd borrow-lend-ledger\n    ```\n2.  **Install dependencies:**\n    ```bash\n    npm install\n    ```\n3.  **Configure environment variables:**\n    *   Copy the example environment file:\n        ```bash\n        cp .env.example .env\n        ```\n    *   Edit the `.env` file and set the `VITE_API_BASE_URL` to the base URL of your running **conceptual backend API**.\n        ```dotenv\n        # Example .env content\n        VITE_API_BASE_URL=http://localhost:3001/api # Replace with your actual backend API URL\n        ```\n\n## 🏗️ Usage\n### 🏃‍♂️ Running the MVP\n1.  **Ensure the conceptual backend API is running** and accessible at the URL specified in your `.env` file.\n2.  **Start the frontend development server:**\n    ```bash\n    npm run dev\n    ```\n    This command (defined in `package.json` and described in `commands.json`) starts the Vite development server, typically on `http://localhost:5173`.\n\n3.  **Access the application** in your web browser at the URL provided by Vite (e.g., `http://localhost:5173`).\n\n\u003e [!TIP]\n\u003e ### ⚙️ Configuration\n\u003e - The primary configuration is the backend API endpoint set in the `.env` file via `VITE_API_BASE_URL`. Vite uses this during build time and makes it available to the application.\n\u003e - `vite.config.ts`: Configures the Vite build tool (dev server port, build options).\n\u003e - `tailwind.config.js`: Configures Tailwind CSS theme and content scanning.\n\u003e - `tsconfig.json`: Configures the TypeScript compiler options.\n\n### 📚 Available Scripts\n\nYou can use the following scripts defined in `package.json` (see `commands.json` for descriptions):\n\n-   `npm run dev`: Starts the development server.\n-   `npm run build`: Creates a production build in the `dist/` directory.\n-   `npm run lint`: Lints the codebase using ESLint.\n-   `npm run typecheck`: Performs TypeScript type checking without emitting files.\n\n## 🌐 Hosting\n### 🚀 Deployment Instructions\nThis frontend application is built as a static site and can be deployed to various static hosting providers.\n\n#### Example: Deploying to Netlify / Vercel\n1.  **Build the application:**\n    ```bash\n    npm run build\n    ```\n    This creates an optimized production build in the `dist/` directory.\n2.  **Deploy the `dist` directory:**\n    *   **Netlify:** Use the Netlify CLI (`netlify deploy --prod`) or connect your Git repository via the Netlify dashboard. Set the build command to `npm run build` and the publish directory to `dist`.\n    *   **Vercel:** Use the Vercel CLI (`vercel --prod`) or connect your Git repository via the Vercel dashboard. Vercel typically auto-detects Vite projects. Ensure the Output Directory is set to `dist`.\n3.  **Set Environment Variables:** Configure the `VITE_API_BASE_URL` environment variable in your hosting provider's settings. This variable is needed **during the build process** on the hosting platform.\n\n### 🔑 Environment Variables\n-   **`VITE_API_BASE_URL` (Required at Build Time):** The base URL of the backend API the deployed frontend will communicate with.\n    Example: `https://your-api.example.com/api`\n\n## 🤝 Contributing (Placeholder)\n\u003e [!NOTE]\n\u003e As this is an AI-generated MVP, direct contributions are not typically accepted in the conventional sense. However, feedback and suggestions can be directed to CosLynx.com. If forking, follow standard Git practices.\n\n## 📜 API Documentation (Conceptual Backend)\nThe frontend (`src/services/api.ts`) expects a backend API with the following endpoints. **This MVP only includes the frontend code; the backend must be implemented separately.**\n\n### 🔍 Endpoints\n\n-   **`GET /transactions`**\n    -   **Description:** Retrieves all recorded transactions.\n    -   **Method:** `GET`\n    -   **Response Body (Success - 200 OK):** `application/json`\n        ```json\n        [\n          {\n            \"id\": \"tx_123\",\n            \"lender\": \"Alice\",\n            \"borrower\": \"Bob\",\n            \"amount\": 50.00,\n            \"createdAt\": \"2023-10-27T10:00:00.000Z\"\n          },\n          {\n            \"id\": \"tx_456\",\n            \"lender\": \"Charlie\",\n            \"borrower\": \"Alice\",\n            \"amount\": 25.50,\n            \"createdAt\": \"2023-10-28T11:30:00.000Z\"\n          }\n        ]\n        ```\n    -   **Response Body (Error):** Standard HTTP error codes (e.g., 500 Internal Server Error).\n\n-   **`POST /transactions`**\n    -   **Description:** Creates a new transaction record.\n    -   **Method:** `POST`\n    -   **Request Body:** `application/json`\n        ```json\n        {\n          \"lender\": \"David\",\n          \"borrower\": \"Eve\",\n          \"amount\": 100.75\n        }\n        ```\n    -   **Response Body (Success - 201 Created):** `application/json` (The newly created transaction object)\n        ```json\n        {\n          \"id\": \"tx_789\",\n          \"lender\": \"David\",\n          \"borrower\": \"Eve\",\n          \"amount\": 100.75,\n          \"createdAt\": \"2023-10-29T14:00:00.000Z\"\n        }\n        ```\n    -   **Response Body (Error):** Standard HTTP error codes (e.g., 400 Bad Request for invalid data, 500 Internal Server Error).\n\n### 🔒 Authentication\n-   No authentication is implemented or expected by the frontend MVP. The conceptual backend API is assumed to be open or handle authentication independently if required.\n\n### 📝 Examples (Conceptual `curl`)\n\n```bash\n# Get all transactions\ncurl http://localhost:3001/api/transactions\n\n# Add a new transaction\ncurl -X POST http://localhost:3001/api/transactions \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"lender\": \"Frank\", \"borrower\": \"Grace\", \"amount\": 15.00}'\n```\n\n\n\u003e [!NOTE]\n\u003e ## 📜 License \u0026 Attribution\n\u003e\n\u003e ### 📄 License\n\u003e This Minimum Viable Product (MVP) is licensed under the [GNU AGPLv3](https://choosealicense.com/licenses/agpl-3.0/) license.\n\u003e\n\u003e ### 🤖 AI-Generated MVP\n\u003e This MVP was entirely generated using artificial intelligence through [CosLynx.com](https://coslynx.com).\n\u003e\n\u003e No human was directly involved in the coding process of the repository: borrow-lend-ledger\n\u003e\n\u003e ### 📞 Contact\n\u003e For any questions or concerns regarding this AI-generated MVP, please contact CosLynx at:\n\u003e - Website: [CosLynx.com](https://coslynx.com)\n\u003e - Twitter: [@CosLynxAI](https://x.com/CosLynxAI)\n\n\u003cp align=\"center\"\u003e\n  \u003ch1 align=\"center\"\u003e🌐 CosLynx.com\u003c/h1\u003e\n\u003c/p\u003e\n\u003cp align=\"center\"\u003e\n  \u003cem\u003eCreate Your Custom MVP in Minutes With CosLynxAI!\u003c/em\u003e\n\u003c/p\u003e\n\u003cdiv class=\"badges\" align=\"center\"\u003e\n\u003cimg src=\"https://img.shields.io/badge/Developers-Drix10,_Kais_Radwan-red\" alt=\"\"\u003e\n\u003cimg src=\"https://img.shields.io/badge/Website-CosLynx.com-blue\" alt=\"\"\u003e\n\u003cimg src=\"https://img.shields.io/badge/Backed_by-Google,_Microsoft_\u0026_Amazon_for_Startups-red\" alt=\"\"\u003e\n\u003cimg src=\"https://img.shields.io/badge/Finalist-Backdrop_Build_v4,_v6-black\" alt=\"\"\u003e\n\u003c/div\u003e","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoslynx%2Fborrow-lend-ledger","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcoslynx%2Fborrow-lend-ledger","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoslynx%2Fborrow-lend-ledger/lists"}
