Despite the fact that Gutenberg developers did not care at all about
uses of this library outside WordPress until last year[0], and that it
is almost impossible to do something that goes beyond the very basic
without using “private APIs”, they insist that the isolated block
editor should be “deprecated”[1].
I do not particularly care much about the isolated block editor, as it
_does_ use all these private APIs and, thus, it is very difficult to
use unless you use the exact same dependencies, otherwise it emits a
weird error regarding “unlocking” things that are not “locked” (i.e.,
the new-fangled way of “protecting” private APIs[2]). And,
apparently, things got easier with Gutenberg 18.5 with the
introduction of the BlockCanvas.
However, it is still a very frustrating experience, and the
documentation for most components and packages is next to
non-existent.
Nevertheless, i managed to get a barely functional editor that still
has some missing features, like the color of rich texts’ highlight
format[3], but it i believe it is a good base to grow the custom
editor on top of.
