Class: IncomingMessage

Process: Main
This class is not exported from the 'electron' module. It is only available as a return value of other methods in the Electron API.

IncomingMessage implements the interface and is therefore an EventEmitter.

Event: ‘data’

Returns:

• chunk Buffer - A chunk of response body’s data.

The data event is the usual method of transferring response data into applicative code.

Event: ‘end’

Event: ‘aborted’

Emitted when a request has been canceled during an ongoing HTTP transaction.

Event: ‘error’

Returns:

error Error - Typically holds an error string identifying failure root cause.

Emitted when an error was encountered while streaming response data events. For instance, if the server closes the underlying while the response is still streaming, an error event will be emitted on the response object and a close event will subsequently follow on the request object.
