Lots of great information, not sure if the echo in the YouTube video was a result of my computer malfunctioning.
However, I am re-inquiring into how much of the evolution of the PB API will affect the ability of PB to operate in a stand-alone environment (i.e., a PB server not connected to the Internet, acting as a mobile WiFI system)?
To re-answer your question from last fall, only uses of Pressbooks that involve communication with remote websites will be limited by working in an “offline” mode. The REST API allows a variety of additional features that involve communication between different Pressbooks networks. None of these features would work without a network connection anyway so you don’t lose out on them by running Pressbooks “offline”.
(As a sidenote, I sometimes use the Airplane Mode plugin when I’m working on Pressbooks in areas with spotty internet connections (e.g. on VIA Rail ) and most core functionality behaves as expected.)
I’m referring to any situation where Pressbooks is run on a local environment (e.g. not a remote server) and accessed from that same local environment. So yes, that would include something like MAMP, or Laravel Valet, or Vagrant, or anything else that fits the bill. I think you’d mentioned running Pressbooks on a Raspberry Pi and accessing it from the same host— that would be the same thing.
