That moment when you work the whole day to write a discord bot from scratch. No discord.py and other wrappers. Pure websockets, oauth2, https, json loads here and there. Understanding how the discord API works was a real challenge, but I did it :).
Most of my time was spent on discord's gateway connection and identification system.

The bot can renew its token, get all the guilds it is part of, all the channels and users of these guilds, send message and communicate with the gateway.

Tomorrow I will start connecting it to a voice channel and let it "speak". Thinking of combining text-to-speech with it, but I am not sure how well they are going to harmonize together.
