To improve reliability of live streams (#59) on Safari.
Safari was dropping the cookie from websocket update requests.
(But it worked sometimes. I don't get why.) I saw folks on the Internet
thinking this related to HttpOnly:
* https://developer.apple.com/forums/thread/104488
* https://stackoverflow.com/q/47742807/23584
but I still see this behavior without HttpOnly. SameSite=Strict vs
SameSite=Lax appears to make a difference. Try that instead.
SameSite=Strict is pointless for us anyway as noted in a new comment.
Turning off HttpOnly would be more unfortunate security-wise.
I'm tired of all the boilerplate, so use the new
GPL-3.0-linking-exception license identifier instead in all the server
components.
I left the ui stuff alone because I'm just going to replace it (#111).
Add a checker for the header because it's easy to forget.
I want to make the project more accessible by not expecting folks to
match my idiosyncratic style. Now almost [1] everything is written
in the "standard" style. CI enforces this.
[1] "Almost": I used #[rustfmt::skip] in a few sections where I felt
aligning things in columns significantly improves readability.
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.
