This is the config I'm running:

services.librespot = {
  enable = true;
  settings = {
    disable-audio-cache = true;
    disable-discovery = true;
    enable-oauth = true;
    name = "${nixosConfig.networking.hostName}";
    backend = "pulseaudio";

    # Hands off
    initial-volume = 100;
    volume-ctrl = "fixed";

    bitrate = 320;
    enable-volume-normalisation = true;
    normalisation-method = "basic";
  };
};

As far as integration goes, I only bothered to set the default storage paths. Not sure what else there is to do really. Discovery requires firewall configuration at the NixOS level, we can't touch that. Setting the default backend to pulseaudio based on system configuration is a possibility but none of the other similar modules do this.
