   By default, a script file which starts a webserver is configured for 'ScriptFilePath' at installer\esb\samples\nodejs\httpserver. The path can be changed by editing the ScriptFilePath property and the script file can be customized if required by accessing the file from the saved location.

   3. mac: .dylib
7. Delete the extracted folder.
