How to check if message contains emojis using discord.js?

You can check if a message contains emojis by using regular expressions in Discord.js. Here's an example code snippet to achieve this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('message', (message) => {
    // Define a regular expression to match emojis
    const emojiRegex = /<:.+:d+>/;

    // Check if the message content contains emojis
    if (emojiRegex.test(message.content)) {
        console.log('Message contains emojis!');
    }
});

client.login('your-bot-token');

In this code, we create a regular expression emojiRegex that matches the pattern of custom Discord emojis (<:name:id>). We then use the test() method to check if the message content contains any emojis. If the test result is true, it means that the message contains emojis and we log a message to the console.
