SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Developers often end up with monolithic Streamlit scripts that become hard to read, test, and extend. This Skill helps keep Streamlit applications maintainable by providing guidelines for separating UI from business logic and for organizing files.

Core Features & Use Cases

Guidance on when to keep a single file versus when to split into multiple modules.
Recommended directory layout with a main streamlit_app.py, an app_pages folder for page-specific UI, and a utils folder for data processing and API helpers.
Best practices such as avoiding the if __name__ == "__main__" guard in Streamlit files and placing it only in utility modules.

Quick Start

Create a Streamlit project scaffold with a main file named streamlit_app.py, an app_pages directory for UI pages, and a utils directory for helper modules.

FAQPage Schema

How do I structure a Streamlit app with multiple pages and shared utilities?▼

To structure a Streamlit app for multiple pages, use a main `streamlit_app.py` file, an `app_pages` folder for page-specific UI, and a `utils` folder for data processing and API helpers to ensure separation of concerns.

When should I split my Streamlit code into multiple modules?▼

You should split Streamlit code into multiple modules when your application requires multiple pages, shared utilities, or testing of business logic outside the UI, transitioning from a monolithic script to a maintainable directory layout.

Why does my Streamlit app not work with the if __name__ == "__main__" guard?▼

Streamlit apps avoid the `if __name__ == "__main__"` guard in UI files because Streamlit manages the execution loop itself. You should place this guard only in utility modules to allow testing of business logic outside the UI.

What is the best way to separate business logic from Streamlit UI components?▼

The best way to separate business logic from Streamlit UI components is by creating a standard directory layout that isolates UI modules in an `app_pages` folder and places data processing helpers in a dedicated `utils` folder.

Can I test my Streamlit application's business logic outside the UI?▼

Yes, you can test Streamlit application business logic outside the UI by separating logic modules into a `utils` folder and using the `if __name__ == "__main__"` guard within those utility modules for direct execution and testing.
