Neither of those dependencies are required for normal operation.

well you right it is warn for required dependencies but i wish this not showing when installing RPC so people don't get confused

C:\Users\pc\AppData\Roaming\Spotify\Discord-Spotify-RPC>npm install
npm WARN discord.js@12.0.0-dev requires a peer of sodium@^2.0.0 but none is installed. You must install peer dependencies yourself.
npm WARN discord.js@12.0.0-dev requires a peer of zlib-sync@^0.1.0 but none is installed. You must install peer dependencies yourself.
