Using node-RED to mock out restful webservices

I am trying to create a restful webservice that returns parameters. I found a tutorial that I think would assist me but I am unable to find the file storage node, see point 3 https://www.arhs-group.com/using-node-red-to-mock-out-restful-webservices/

I assume that the file storage node is no longer available?

Can anyone assist me in appending key/value pairs to the url?

Thanks

Isn't that just a File node? That should be already installed as part of node-red I think.

Hi, its not installed on my node-red and when I search for file or storage it does not appear, perhaps its deprecated?

Where is your Node-RED installed ? The file nodes don’t exist on Bluemix for example as storage is provided via cloudant service.

Ahh, my node-red is installed on Bluemix (IBM Cloud).

Now that you have enlightened me I have used a mongo database instead and that seems to be working (I am not familiar with Cloudant).

Thanks.
