Fuel Tracker is a simple, yet powerful web application designed to help users track their vehicle's fuel expenses and consumption. It is built using the MERN Stack (MongoDB, Express, React, Node.js).

• ✨ Features
• 🚀 Technology Stack
• 🛠️ Project Setup
• 🔑 Key Code Implementation

The following features and functionalities are integrated into the application, designed for better user experience and data accuracy:

• Login & Registration 🔑: Secure user sign-up and sign-in process.
• Consistent UI 🎨: Login and Register forms share an identical interface design, and include the Password Show/Hide feature (using the eye icon).
• Profile Management 👤: Allows users to update their personal details.
• Permanent Account Deletion (Danger Zone) 🗑️: Provides the option, with strong confirmation and warning, to permanently delete the user's account and all associated data from the server.

• Data Entry ⛽: Record fuel entries (Date, Time, Liters, Price per Liter, Odometer reading).
• Accurate Cost Calculation 🧮: Total Cost calculation (Liters * Price) is automatically fixed to two decimal places for accurate currency representation (e.g., 2382.66).
• History & Listing 📜: Displays a detailed list of all recorded entries.
• Edit & Update ✏️: Provides the functionality to edit existing fuel entries.

• Dashboard Summary 📈: Shows a summary of key metrics, including total spent and average fuel rate.

The project is divided into two parts: the Backend (API) and the Frontend (Client).

1. Clone the repository and navigate to the backend directory:

   git clone [https://github.com/abdullahislam123/fuel-tracker-app](https://github.com/abdullahislam123/fuel-tracker-app)
   cd backend 

2. Install the necessary dependencies:

   npm install

3. Create a .env file and configure the following variables:

   PORT=5000
   MONGO_URI=<Your MongoDB Atlas Connection String>
   JWT_SECRET=<Any Unique Secret Key>
   

4. Start the backend server:

   npm start 

   The server will be running on port 5000.

1. Navigate to the frontend directory:

   cd frontend 

2. Install dependencies:

   npm install

3. API URL Configuration: In the relevant source file, ensure the API URL is set to your local server: http://localhost:5000.

4. Start the frontend application:

   npm run dev

   The app will load in your browser.

The cost calculation in AddFuel.jsx and History.jsx uses the .toFixed(2) method to ensure that all saved and displayed currency values are accurate to two decimal places.

The backend uses the dedicated DELETE /profile route to ensure the user's account and all associated fuel entries are atomically and permanently deleted from the database.

Use the following standard commands to push your changes to GitHub and trigger a deployment (if connected to platforms like Vercel or Netlify):
