For the past few weeks, I have been experiencing an issue with Dataslayer. After some time, it stops displaying newly sent events. The issue is temporarily resolved when I restart DevTools and refresh the page; however, this also clears the previously loaded data layers.
dataslayer is back! God Bless thank you for working on this guys
верните расширение!
So glad dataslayer is back! Best tool out there for debugging the data layer
I love this extension, but suddenly it disapear from my dev tool bar, and i can't have it back anymore
DONT USE THIS TOOL, it displays false results that didn't happen. Example: I'm on URL A and I click a button. -According to Google Tag Assistant (essentially the word of God), this click happened on URL A (duh, of course it did). -According to Dataslayer? Oh it happened on URL B, the place that the button click took me to. Thats literally impossible, but Dataslayer doesnt care. I didnt realize that the name meant that the data itself would be slayed until it's no longer usable. I've tried to capture my thoughts about how insane and ridiculous that is, but I keep failing to accurately capture it. It's nuts. This tool has major issues parsing events properly and the results is that it outright falsifies what happened and makes you question your sanity, until Google tag assistant confirms its not you, it's Dataslayer.
Lets you see events from previous sessions, which is what I needed it for.
if its got a Slayer background image, it worth it
The interface is really awkward. It would be nice to rework how the data is presented. Becomes hard to work with. But the backend is amazing. Just looked through the source to see how it gets all DEs. _satellite._container.dataElements Pretty cool. Didn't realize _satellite gave access to all DEs.
Works great! Easy to use and allows you to see quickly what's happening with your tagging and data.
