import asyncdispatch, discordnim

let bot = newShard("Bot KEY")  # KEY is a valid Discord "Token" Key

proc f(b: Shard, m: MessageCreate) =  # Async Event Handler 
  discard b.channelMessageSend(m.channel_id, m.content)

discard bot.addHandler(EventType.message_create, f) # Hook Handler

waitFor bot.startSession()  # Run Bot

• Ideally you need to add asyncCheck instead of discard, and a disconnect() at exit for the bot, but basically is a working async chat bot!.

import asyncdispatch, os, discordnim

let bot = newShard("Bot " & getEnv("DISCORD_TOKEN"))  # DISCORD_TOKEN is a valid Discord "Token" Key

proc callback(bot: Shard, mesage: MessageCreate) =  
  ## Async Event Handler 
  if mesage.author.id != bot.cache.me.id: # Bot wont reply itself
    echo mesage.content
    case mesage.content # case switch on message content
    of "!help":         # message content is "!help"
      asyncCheck bot.channelMessageSend(mesage.channel_id, "Some help")
    of "!ping":         # message content is "!ping"
      asyncCheck bot.channelMessageSend(mesage.channel_id, "pong")
    else:               # message content is something else                 
      asyncCheck b.channelMessageSend(mesage.channel_id, mesage.content)


discard bot.addHandler(EventType.message_create, callback) # Hook Handler


when isMainModule:
  try:
    echo "Starting Discord Bot"
    waitFor bot.startSession() # Run Bot
  finally:
    echo "Stopping Discord Bot"
    waitFor bot.disconnect()   # Stop Bot
