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.

Examples
