Project description
PyPositron
PyPositron is a Python-powered desktop app framework that lets you build cross-platform apps using HTML, CSS, and Python—just like Electron, but with Python as the backend. Write your UI in HTML/CSS, add interactivity with Python, and run your app natively!
Features
- Build desktop apps using HTML and CSS.
- Use Python for backend logic.
- Virtual environment support.
- Effecient installer creation for easy distribution (the installer automatically finds an existing browser instead of installing a new one for every app like Electron.JS).
Quick Start
1. Create a New Project
Install PyPositron if not already installed:
pip install py-positron
Them create a new project using the CLI:
positron create
# Follow the prompts to set up your project
cd <your_app_name>
2. Run Your App
positron start
3. Install Python Packages
positron install <package>
4. Create a Virtual Environment
positron venv
