It depends on the library that you have `required` but for the above example :

```auto
[{"id":"0bd4a2216f8d1ed7","type":"inject","z":"4895ea10b4ee9ead","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":370,"y":1000,"wires":[["a6b4049859c21f21"]]},{"id":"a6b4049859c21f21","type":"function","z":"4895ea10b4ee9ead","name":"","func":"msg.payload = cowsay2.say('hi')\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[{"var":"cowsay2","module":"cowsay2"}],"x":550,"y":1000,"wires":[["2cfb705c6e0cbcb2"]]},{"id":"2cfb705c6e0cbcb2","type":"debug","z":"4895ea10b4ee9ead","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":730,"y":1000,"wires":[]}]
