As expected, it seems to work just fine. Haven't had time to do extensive testing and haven't loaded old flows. But created some simple flow tabs and they all seem to work ok.
Not unexpected since W11 is mostly still W10 with a revamped UI. (Yes I know there are some underlying changes but lets not quibble )
I installed the official MSI installer for Node.js then installed Node-RED with the usual
npm install -g node-red then started it with
node-red. Created some flows and tabs, tried a restart. All working fine with no errors at all.
Note that, as mentioned in my other recent post, you no longer need to install the
windows-build-tools since the official node.js installer now includes them directly.
If you do get any errors, I would suggest starting a new thread with the details.
Incidentally, I'm still running the insider builds for W11 and I'm not yet on the latest. I am currently running 22000.168 installed on 2021-06-29 though with all current patches. I use Microsoft Edge browser and I'm on v95.0.1020.44. Running on a Microsoft Surface Pro 7.
