building-streamlit-multipage-apps

To build a multi-page Streamlit app, you scaffold a main streamlit_app.py module and an app_pages directory. This structure provides a cohesive user experience with a top navigation bar across 3 to 7 pages.

State management in a Streamlit multipage app allows you to share global state across pages while keeping page-specific context isolated. This ensures state remains consistent and maintainable throughout the app.

The best way to organize multiple pages in a Streamlit dashboard is using an app_pages directory with a clear naming convention. This maintainable structure simplifies collaboration and extension as your app scales.

Yes, you can enable a top navigation bar by creating a central main module and organizing pages under the app_pages directory. This provides structured navigation for switching between modules.

You need a modular app architecture when your Streamlit dashboard requires scalable page organization and consistent global state handling. This approach prevents state management issues as your application grows.
