This is Discord Server Info NPM.

YOU NEED TO USE DISCORD.JS FOR THIS TO WORK

Example:

const Discord = require('discord.js')
const client = new Discord.Client()

const Info = require('discord_server_info')

client.on('ready', (message) => {
  Info.BotInfo(client).then(r => console.log(`Guilds: ${r.guilds}\nUsers: ${r.users}`)).catch(console.log)
})

The BotInfo function returns an object, Inside the object there is both guilds and users.
