How to Get the User ID of the First Reaction on Discord with discord.js

When building a Discord bot with discord.js, you may want to track who reacts to your messages and when they do. This is particularly useful for games, polls, or any interactive features where timing is crucial. But how do you retrieve the user ID of the first person who reacts to your message? In this guide, we’ll walk through a practical solution to this common problem.

Understanding the Problem

You have a bot that sends a message and adds a reaction (like ⛔) to it. Your goal is to capture the first user who reacts to that message and fetch their user ID. You might have started writing your code but are unsure how to extract this information after the reaction event occurs. Let’s dive into the code to get this functionality working.

Solution Overview

To capture the first reaction and obtain the user ID, you will primarily work with the awaitReactions() method provided by discord.js. This method listens for reactions on a specified message, allowing you to grab the first one that comes in.

Step-by-Step Implementation

Sending the Message: Start by sending a message to the channel and adding a reaction.

Waiting for Reactions: Use awaitReactions() to listen for reactions on the message. Set the time limit and specify the maximum number of reactions you want to capture.

Handling the Collected Reaction: Once a reaction is collected, use .then() to process it. You can easily extract the first reaction using collected.first().

Capturing the User ID

With the first reaction in hand, you can now retrieve the user and their ID using the following code:

In this section:

firstReaction.users.cache.first() retrieves the user object related to the reaction.

We then access the id property to get the user's ID.

Conclusion

In this post, we walked through a simple yet effective way to fetch the user ID of the first person who reacts to a message in your Discord bot using discord.js. By following these steps, you can enhance your bot's interactivity and make it more engaging for users. Remember to handle errors appropriately so that your bot can respond gracefully in case of issues.

Feel free to experiment with this method, and happy coding!
