I had to implement gzip request handling and found this thread useful. I put together a small library based on the discussion I found here. Right now, the lib only handles content-encoding: gzip, but it can easily be extended to handle more content-encodings.
:zlib.gunzip/1 is great if you know you can trust the input, but if your endpoint is exposed to the internet, you could be vulnerable to a zip bomb attack, so instead I used :zlib.safeInflate/2. I hope someone finds it useful.
