Serving multiple applications

If you want to serve more than one app on a single server you can use the pn.serve function. By supplying a dictionary where the keys represent the URL slugs and the values must be either Panel objects or functions returning Panel objects you can easily launch a server with a number of apps, e.g.:

import panel as pn
pn.serve({
    'markdown': '# This is a Panel app',
    'json': pn.pane.JSON({'abc': 123})
})

Note that when you serve an object directly all sessions will share the same state, i.e. the parameters of all components will be synced across sessions such that the change in a widget by one user will affect all other users. Therefore you will usually want to wrap your app in a function, ensuring that each user gets a new instance of the application:

def markdown_app():
    return '# This is a Panel app'

def json_app():
    return pn.pane.JSON({'abc': 123})

pn.serve({
    'markdown': markdown_app,
    'json': json_app
})

You can customize the HTML title of each application by supplying a dictionary where the keys represent the URL slugs and the values represent the titles, e.g.:

pn.serve({
    'markdown': '# This is a Panel app',
    'json': pn.pane.JSON({'abc': 123})
}, title={'markdown': 'A Markdown App', 'json': 'A JSON App'}
)
