Serve Apps#

This guide will show you how-to migrate and serve a Hello World application.

Migration Steps#

You should replace:

  • import streamlit as st with import panel as pn and

  • st.write with pn.panel.

You will have to:

  • add pn.extension to configure your Panel application via optional arguments like sizing_mode and template.

  • add .servable to the Panel objects you want to include in your apps template when served as a web app.

For production you will also have to migrate some of your app configuration to panel serve command line options or environment variables.
