Use today as filter

[niclas.w82]

Hi.

I got several payloads that looks like attached picture with different start dates. Can I somehow just let the messengers pass with todays start date? My idea for now is to start with adjust the format on the date and maybe use a swith node with property payload.start_date and an expression to filter out today.

I am stuck and tried google a lot to solve this without success

For sure you can do this with some jsonata $moment expression in Switch node ..
i took the javascript road if you are interested here is an example flow

Thank you! You guys are really awsome
Exactly what i was looking for.

But i can’t get this to work. Got nothing in debug when importing your examples. Am i running a to old version of node red. V2.2

Best regards

Not wery good in JSONata expressions. But after the split function it is missplaced in the array so it cant´t find the payload in payload.start_date anymore. Can this be the problem?

[niclas.w82]

Thanks again!! Got it to work
