This adds a configurable
open_browser
trait toExtensionApp
s, and refactors theServerApp
to handle browser-opening properly when another app, e.g. anExtensionApp
, starts the server.This also adds a property,
starter_app
, toServerApp
that enables theServerApp
to know when an extension started the app (versus starting the server directly).This will help address this issue seen in JupyterLab: jupyterlab/jupyterlab_server#145
A follow up PR in JupyterLab is needed to use this new trait.
