class Session
The inspector.Session is used for dispatching messages to the V8 inspector
back-end and receiving message responses and notifications.
Constructors #
#Session() Create a new instance of the inspector.Session class.
The inspector session needs to be connected through session.connect() before the messages can be dispatched to the inspector backend.
