Session - inspector - Node documentation

class Session

extendsEventEmitter

The inspector.Session is used for dispatching messages to the V8 inspector back-end and receiving message responses and notifications.

Constructors

new

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.

connect(): void

Connects a session to the inspector back-end.

connectToMainThread(): void

Connects a session to the inspector back-end. An exception will be thrown if this API was not called on a Worker thread.

disconnect(): void
