* hide the end day selector away when it's not in use.
It was confusing, especially since it seemed to have
a purely black circle over the selected date when disabled.
* add a "Time" label to the time selectors. On desktop,
this isn't entirely necessary because they have clock icons
and "hh:mm:ss" annotations. But on mobile, they were entirely blank,
so it was unclear what they were for.
It worked fine on my laptop with node.js v14.15.4, but not on my
new workstation with node.js v12.18.2 (as comes with Ubuntu 20.10).
It would print "Unexpected token '?'" without any clue what file the
error is in. I'm trying to fix that here:
https://github.com/facebook/create-react-app/pull/10652
(and various other lockfile upgrades. "npm audit" is clean.)
The date picker to use with 4.0 is unmaintained, and the new one is
apparently quite different.
Given that 5.0 is expected to be released this quarter, I prefer to
jump straight to the new one and get things working with it, even if
it means using an alpha in the short-term.
Besides being more clear about what belongs to which, this helps with
docker caching. The server and ui parts are only rebuilt when their
respective subdirectories change.
Extend this a bit further by making the webpack build not depend on
the target architecture. And adding cache dirs so parts of the server
and ui build process can be reused when layer-wide caching fails.
