I'm pre-zipping static content before bundling it in a Docker container.
This allows me to serve static content gzipped if there's an accept-encoding header that contains gzip without putting extra load on the CPU when serving gzipped content.
gzip -rk9 ./build/processedResources/jvm/main/static/* || exit

I wanted to add support for Brotli if the accept-encoding header contains br and then serve whichever one is smaller, file.ext.br or file.ext.gz
brotli -rk9 ./build/processedResources/jvm/main/static/* || exit

Turns out -k and -9 does exactly the same as gzip, but the -r flag is not supported which caught me by surprise.

Short-term workaround is to use find ... | args ... | brotli -k9 after I've extensively studied the find and xargs man pages, long-term, it would be nice if I can just do -r and save the hassle of using 3 commands to do one thing.

Oh, never noticed that option in gzip. Sounds like a good addition. Will implement it, when I have spare cycles. Thanks for the heads-up.
