Function or Node to get the modified date from a file

General
1

Hi
I need to look at this file, and if it's modified within the last 2 sec. then that will run a flow.
/config/www/snapshots/foran_detection_latest.jpg

I just don't know where to start with a function or what Node too use, in my case.

Can someone guide me ?

Hi and welcome.

Have you tried the watch node?

Hi and Thx. :slight_smile:

Is it this one ?
node-red-contrib-watchdirectory (node) - Node-RED

Then yes and can see that i can "Type event : update" but how do I look at it and see if it's within 3 sec. from now ?

Ahh the build-in watch, no..
I add the filepath and filename to the name, and then i'm stuck.

The watch node is a core node and pre installed, you can watch for any changes to a file. So if a file is updated the watch node should catch it. No need to wait 3 seconds.

Add a debug then update the file and see what you get in the debug node.

What... :slight_smile:
Was it so easy... sry then... but then I hope I can ask in addition to this.
Can see the debug note gives me 7..

"/config/www/snapshots/terrasse_detection_latest.jpg"

That will trigger a flow 7 time for the same update.. right?
If so, how do I get it to run only once for each update.

Filter msg using trigger node, to only receive one.
e.g.
