How to Efficiently Fetch All Reactions from a Specific Message in Discord.js

If you're building a Discord bot using Discord.js, you might find yourself in a situation where you want to fetch all the reactions from a specific message. This task entails retrieving various information for each reaction, including the emoji's name, the users who reacted, and the count of reactions.

In this guide, we're going to walk through how to accomplish this in a clear and organized manner.

The Problem

Imagine you want your bot to provide insights on specific messages, like knowing how many users reacted with a smiley face, who those users are, and so forth. Here are the elements we need to fetch:

Emoji Name: such as :smile:

Users Who Reacted: for example, RandomUser# 4654, ILikePotatoes# 1639

Count of Reactions: e.g., Count: 2

Attempting to achieve this using the ReactionCollector may lead to issues since it only captures fresh reactions occurring after the event is started, leaving you unable to access historical data. Alternatives like the discord-fetch-all module can also be unreliable, often resulting in pending promises or undefined outputs.

But don't worry! There's a straightforward solution to this problem using Discord.js.

The Solution

Step 1: Fetch the Message

To begin with, you need to retrieve the specific message using its ID. Use this command to fetch the message from a designated channel:
