Technologies Used

• Backend: Python with Flask

  • Flask is a lightweight WSGI web application framework in Python. It is designed with simplicity and flexibility in mind, making it ideal for building small and scalable web applications. Flask handles routing, request handling, and templating in this project.

• Frontend: HTML, CSS

• Database: SQLite

  • SQLite is a self-contained, high-reliability, embedded, SQL database engine. It requires no setup or server and stores data in a single file. In this project, SQLite initializes the database structure and ensures persistent task storage.

• Tools: Jinja2 for templating

Installation and Setup

1. Clone the repository:

   git clone https://github.com/harshavardhant2005/Todo-app-.git
   cd todo-app

2. Create a virtual environment and install dependencies:

   python -m venv venv
   source venv/bin/activate  # For Windows: venv\Scripts\activate
   pip install flask

3. Initialize the SQLite database:

   • Ensure the Todo.db file is created by running the Flask app for the first time. The app contains code to automatically initialize the database schema if it does not exist.

4. Run the application:

   python app.py

After initializing the server, click on the running server link to open the application.
