You can always use it as a piece of your workflow, given its not all incompassing for your needs.
But given that the Angular implementation was not kept up to date, I’m not sure if these types of frameworks have an immediate future in Pinegrow as an integrated workflow, but it sure would be nice. Of course React and Vue are now considered much more popular than Angular.
I thought there was a post somewhere where I saw mention of Angular and a few frameworks eventually being dropped from within Pinegrow but I can’t seem to find it (so maybe I am mistaken).
