Discord Message Triggered After # Reactions

kangabru — kangabru

Sends a message to Discord if the number of reactions on a message pass a certain threshold and has extra checks to ensure this only happens once.

const lib = require('lib')({token: process.env.STDLIB_SECRET_TOKEN});
const { message_id, channel_id } = context.params.event

// ** Set your config here ***
const emoji= '👍';
const triggerCount = 3;
const triggeredMessage = `This message was triggered after ${triggerCount} ${emoji} reactions`

// Is this the right emoji?
if (context.params.event.emoji.name !== emoji) return

const botId = (await lib.discord.users['@0.1.4'].me.list()).id;

// We use the bot's reaction to prevent mutliple triggers.
// Get the existing reactions and check if the bot has reacted.
let reactions = await lib.discord.channels['@0.1.2'].messages.reactions.list({
  emoji, message_id, channel_id,
});

const botHasReacted = !!reactions.find(x => x.id === botId)

if (!botHasReacted && reactions.length >= triggerCount) 
{
  // React with emoji so we know the lock the trigger
  await lib.discord.channels['@0.1.2'].messages.reactions.create({
    emoji, message_id, channel_id,
  });
  
  // Send triggered message
  await lib.discord.channels['@0.1.2'].messages.create({
    channel_id, content: triggeredMessage,
  });
