An unexpected error has occurred in Discord.js: ReferenceError - DiscordCollection is not recognized

While working on my Discord bot using Discord.js and following Codelyon's code, I encountered an error that has me stuck:

ReferenceError: DiscordCollection is not defined at Object.<anonymous>
const {Client, Intents, DiscordAPIError, Collection} = require('discord.js');

const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });

const prefix = '-';

const fs = require('fs');

client.commands = new DiscordCollection();

const commandFiles = fs.readdirSync(`./commands/`).filter(file => file.endsWith(`.js`));
for(const file of commandFiles){
    const command = require(`./commands/${file}`);

    client.commands.set(command.name,command);
}

client.once('ready', () => {
    console.log('Ceeby Is Online');
})

client.on('message', message => {
    if(!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).split(/ +/);
    const command = args.shift().toLowerCase();

    if(command === 'ping'){
        client.commands.get('ping').execute(message, args);
    }
})
client.login('TOKEN')

Answer №1

There are two commonly used approaches for importing and utilizing libraries like discord.js: either importing the entire module or utilizing object destructuring. Examples of both methods are provided below. It appears that you may be attempting to combine both techniques, by destructuring the object but referencing Discord.Client and Discord.Collection instead of simply using Client and Collection.

Using the Whole Module

const Discord = require('discord.js');
...
const client = new Discord.Client({ intents: ['GUILDS', 'GUILD_MESSAGES'] });
...
client.commands = new Discord.Collection();

Object Destructuring Method

const { Client, Collection, DiscordAPIError } = require('discord.js');
...
const client = new Client({ intents: ['GUILDS', 'GUILD_MESSAGES'] });
...
client.commands = new Collection();
