Flask SQLite Example

This is a simple Flask app that demonstrates how to create a web application with SQLite database integration. The app allows users to add their first name and last name, which gets stored in an SQLite database.

Prerequisites

• Python 3.x installed on your machine.
• Git installed.
• Docker installed.

Setup

1. Clone the repository:

   git clone https://github.com/your-username/flask-sqlite-example.git

2. Navigate to the project directory:

   cd flask-sqlite-example

Run the Flask App Locally

3. (Optional) Create a virtual environment:

   python -m venv venv

   Activate the virtual environment:

   • On Windows:

     .\venv\Scripts\activate

   • On macOS/Linux:

     source venv/bin/activate

4. Install the required dependencies:

   pip install -r requirements.txt

5. Run the Flask app:

   python app.py

   The app will be accessible at http://127.0.0.1:5000/ in your web browser.

Create a Docker Image

6. Create a Docker image:

   docker build -t flask-sqlite-example .

7. Run the Docker container:

   docker run -p 5000:5000 flask-sqlite-example

   The app will be accessible at http://127.0.0.1:5000/ in your web browser.

View SQLite Database

8. (Optional) Install DB Browser for SQLite.

9. Open database.db in the src directory using DB Browser for SQLite to visualize the data.
