Question

Obtain a compilation of users who have expressed their reaction to a message with a specific emoji on Discord

Check out this Discord.js code snippet for a Discord bot:

client.channels.fetch('channelID here').then(function (channel) {
 channel.messages.fetch('messageID here').then(function (message) {
  console.log(message.reactions.cache.get('EmojiID here').users);
 });
});

When executed, the console displays the following information:

ReactionUserManager {
  cacheType: [class Collection extends Collection],
  cache: Collection [Map] {},
  reaction: MessageReaction {
    message: Message {
      channel: [TextChannel],
      deleted: false,
      id: 'MessageID here',
      type: 'DEFAULT',
      system: false,
      content: 'What role do you want?\n' +
        'React with:\n' +
        '<:Red:870224025811558450>  for <@&870162738561814578> \n' +
        '<:Blue:870224213976444959> for <@&870162842983206922> \n' +
        '<:Yellow:870224106061172776> for <@&870162885412810773>\n' +
        'You will be assigned the role corresponding to your most recent reaction.\n' +
        'Unreact to remove the role.',
      author: [User],
      pinned: false,
      tts: false,
      nonce: null,
      embeds: [],
      attachments: Collection [Map] {},
      createdTimestamp: 1627548937713,
      editedTimestamp: 1627617831107,
      reactions: [ReactionManager],
      mentions: [MessageMentions],
      webhookID: null,
      application: null,
      activity: null,
      _edits: [],
      flags: [MessageFlags],
      reference: null
    },
    me: true,
    users: [Circular],
    _emoji: ReactionEmoji {
      animated: undefined,
      name: 'Red',
      id: 'EmojiID here',
      deleted: false,
      reaction: [Circular]
    },
    count: 2
  }
}

In the output, count: 2 is shown. To retrieve the list of objects associated with these two users, how can this be accomplished?

Answer №1

You were very close to the solution. The ReactionUserManager is a manager that includes a cache property which returns a collection of User objects.

If you want to fetch the users as well, you can follow this approach:

client.channels.fetch('channelID').then(function (channel) {
 channel.messages.fetch('messageID').then(function (message) {
  const reaction = message.reactions.cache.get('EmojiID')
  reaction.users.fetch().then(function (users) {
    console.log(users)
  })
 })
})

Using async-await in an async function can make the code more readable like this:

const channel = await client.channels.fetch('channelID')
const message = await channel.messages.fetch('messageID')
const reaction = message.reactions.cache.get('EmojiID')
const users = await reaction.users.fetch()

console.log(users)

// For example, you can add a role to each user
users.each(async (user) => {
  // Retrieve the member object as users do not have roles
  const member = await message.guild.members.fetch(user.id)
  member.roles.add('ROLE ID')
})
