How to enable compression (gzip/brotil) in nextcloud-aio?

[SubhashBose]

I want webserver traffic compression for Nextcloud-AIO, but I couldn't find any option to enable this. Is it possible to do this in NC-AIO?

For my setup, I see that NC-AIO sends uncompressed traffic for the UI of ~32MiB but on compression, it can be just ~8MB. That's about 75% compression.
The majority of the compressible traffic is from static assets, like JS and CSS files. The worst is for core-common.js file which is 13MB, but on compression, it is just ~2MB.
So, I think for NC setup compression is very important for having a fast Web-UI loading. I was hoping NC-AIO does compression by default, but that's not the case.

One option can be putting a reverse proxy in between which will handle the compression, but this is not what I want. Nextcloud AIO already runs Apache and Caddy within dockers, and I just don't want to add another webserver in between. Best would be to have the option to enable compression in Apache or caddy which is already included.

Seems like adding: encode zstd gzip to the caddyfile would be enough to do this (https://caddyserver.com/docs/caddyfile/directives/encode), brotli is not supported by caddy by default. I think enabling gzip in apache (not caddy) is also possible, but I think caddy would be enough. @szaimen what do you think about this?

Thanks, this is what I am looking for. In apache, mod_gzip has to be enable to get this. But as you said, for caddy it is just as simple as adding this one line to caddyfile, then no need for apache compression. I hope this is implemented in NC-AIO.

Additionally, if you want, you can add a optional flag to initial docker run to disable compression if some user wants to.

encode zstd gzip sounds good in general but I would probably only enable it for

which seems to be the main problem here to not cause any unexpected sideeffects.

Also @Zoey2936 would this work behind reverse proxies or would we need to disable that for them?

From my experience, compression done by an origin and additional compression by the reverse proxy is no problem

This will be fixed with #2576
