• Frontend: HTML, CSS, Bootstrap 4

Installation

To run this project locally, follow these steps:

Prerequisites

• Python 3.x
• pip (Python package installer)

Setting Up the Virtual Environment (venv)

A virtual environment (venv) is an isolated environment where all the dependencies for your project are contained. This ensures that your project uses its own versions of libraries and doesn't depend on globally installed libraries.

Step 1: Create a Virtual Environment

1. First, make sure you're using an up-to-date version of Python (at least Python 3.6). You can check your version with the following command:

   python --version

2. Create a new virtual environment: python3 -m venv venv

3. Activate the virtual environment: Windows: venv\Scripts\activate macOS/Linux: source venv/bin/activate

Step 2: Install Dependencies

1. Navigate to the project directory: cd my-application

2. Install the required dependencies from the requirements.txt file: pip install -r requirements.txt

Running the Application

1. Run the Flask application: python app.py

Now you can access the application at http://localhost:5000.

1. Login - Connexion

The login functionality allows users to authenticate themselves by entering their username and password. The credentials are validated against the stored data in the MongoDB database, ensuring a secure login process.

2. Sign Up - Inscription

Users can create a new account by providing their username, email, age, and a secure password. The system validates the entered data before storing it in the MongoDB database.

3. Profile - Profil Utilisateur

Each user has a personal profile where they can view and update their information, such as their username, email, and age. Access to the profile is protected and only available after successful authentication.

4. Update Profile - Mise à jour des informations

Users can edit their profile information (name, email, age). The updated details are saved in the database and reflected in real-time on the user’s profile.

5. Password Hashing with Mongo - Hachage du mot de passe

To ensure the security of user passwords, the application hashes passwords before storing them in MongoDB. This process uses a secure hashing algorithm like bcrypt to prevent retrieving the passwords in plaintext, ensuring protection against unauthorized access.
