1 year ago I agree, fantastic tool, with "challenging" documentation. It is, at least for me, a try and error approach... Here is a simple example for EXISTS. All requests follow the same pattern (almost!). Hope this helps.

Hi i'm using your npm on node-red. It's really great !!! but i seem at a lost on how to use each function. for example what should i specify in msg.payload , msg.topic ??. if i want to find whether there is a key inside redis i use EXIST function with msg.topic = "Key"; then what about the other??
If you want more clarification you can tell me and i'll try to explain my problem.
