## Flow editor UI design
In the first version, Node-RED flow editor will support to generate nodes from Swagger definition and function node. “Creating nodes” item will be added under “Export” in the menu.

### Download UI
When Node-RED runtime finished generating original node as tgz file, Node-RED flow editor shows the notification message which has download button. After clicking the button, Node-RED users can download the file to their local PC.

## API design
To realize node generator functionality on Node-RED flow editor, Node-RED runtime has the following additional API endpoints.
