Output Randomiser Node

There are times in a flow when I just want the next node to choose something at random. Other tools like NodeRed have this and its very useful.

I created a code node to achieve this, but would be nicer and more stable to have a simple “Random” node.

const items = [];
const myList = $input.all();
const randomIndex = Math.floor(Math.random() * myList.length);
const randomItem = myList[randomIndex];
return [{ json: randomItem }];

Hey @RedPacketSec,

What sort of random data would you be interested in? We have a “debug helper” node that was released as a community node that can generate some random data.

Let us know what is missing and we can always look at popping in some changes to make it more useful.

Thanks for that, but i need to choose an item from a list at random from the previous node.

Ah ok that is a bit different, We could add it as an option to return a random input item though :thinking:

What does the output randomiser look like in other tools maybe we can get some inspiration.

@RedPacketSec you can do pretty much the same in n8n like in node red:

If you only want less outputs, just change the expression accordingly:

1 output: {{ Math.floor(Math.random() * 1)  }}
2 output: {{ Math.floor(Math.random() * 2)  }}
3 output: {{ Math.floor(Math.random() * 3)  }}
4 output: {{ Math.floor(Math.random() * 4)  }}

EDIT: removed set node as you can just put this expression directly into the switch node

You can choose a random item using the ‘item lists’ node: first sort the items randomly then limit to only return one:
