bokeh.application.handlers.server_lifecycle

Bokeh Application Handler to look for Bokeh server lifecycle callbacks in a specified Python module.

class ServerLifecycleHandler(*, filename: Union[str, os.PathLike[str]], argv: List[str] = [], package: Optional[module] = None)

Load a script which contains server lifecycle callbacks.

Public Data Attributes:

error	If the handler fails, may contain a related error message.
error_detail	If the handler fails, may contain a traceback or other details.
failed	True if the lifecycle callbacks failed to execute

safe_to_fork

Public Methods:

__init__(*, filename[, argv, package])	keyword filename path to a module to load lifecycle callbacks from
url_path()	The last path component for the basename of the path to the callback module.

__init__(*, filename[, argv, package])	keyword filename path to a module to load lifecycle callbacks from
modify_document(doc)	This handler does not make any modifications to the Document.
on_server_loaded(server_context)	Execute on_server_unloaded` from the configured module (if it is defined) when the server is first started.
on_server_unloaded(server_context)	Execute on_server_unloaded from the configured module (if it is defined) when the server cleanly exits.
on_session_created(session_context)	Execute on_session_created from the configured module (if it is defined) when a new session is created.
