Years ago I wrote a server in #go for a customer that handled resizing and serving images on the fly so that they could ditch the 10 or so variants they were storing in the file system and reduce their storage growth. It’s been re-written to simplify things for users, support virtual hosts, quicker, more metrics so you know what’s going on.
Internally it uses libvips, via a somewhat customised and optimised bimg library
I’m considering open sourcing this, would people be interested?
Forgot to add that it supports multiple backends now for fetching source images, the original local file system, HTTP(S) proxy and I planned to add S3 as well but haven’t yet.
