I am working on a Discord bot, and trying to improve my already functioning mand handler. I have a folder, and every file is an extra mand. I want to expand the system, so I have alias name for the same mand, e.g. I want my clearchat mand to function with /clearchat or with /cc, but I dont want to create just another file and copy the code. This is what I have:

// I left out the other imports etc.
clientmands = new Discord.Collection();

// Reading mands-folder
const mandFiles = fs.readdirSync("./mands/").filter(file => file.endsWith(".js"));
for (const file of mandFiles) {
    const mand = require(`./mands/${file}`);
    clientmands.set(mand.name, mand); 
}

client.on("message", msg => {

    if (msg.content.startsWith(config.prefix) && !msg.author.bot && msg.guild) {
        const args = msg.content.slice(config.prefix.length).split(" ");
        const mand = args.shift().toLowerCase();
        
        if (clientmands.find(f => f.name === mand)) {
            clientmands.get(mand).execute(client, msg, args);    
        }
    }
});

and then a mand file inside the mands-folder:

module.exports = {
    name: "clearchat",
    execute(client, msg, args) {
        if (msg.member.hasPermission("ADMINISTRATOR")) {
              msg.channel.messages.fetch({limit: 99}).then(messages => {
                  msg.channel.bulkDelete(messages);
              });
        }
    }
}

(I know it only deletes 100 messages max, I am fine with that)

I image something in changing a few lines in my client.on("message) function, and just having to write in the clearchat.js file a line like name: ["clearchat", "cc", ...] where I can go writing as much aliases as I want.

Thanks in advance!

• javascript
• node.js
• discord.js

• I think we have to assume, that every alias/name is used only a single time – pragmatrick Commented Jul 28, 2020 at 17:37

First, you'll have to create an array with the aliases in your mand.

module.exports = {
    name: "clearchat",
    aliases: ["cc"],
    execute(client, msg, args) {
        
    }
}

Then, the same you did with mands, create a Collection for the aliases.

client.aliases = new Discord.Collection()

And finally, bind the alias to the mand:

if (mand.aliases) {
    mand.aliases.forEach(alias => {
        client.aliases.set(alias, mand)
    })
}

Now, when you want to execute a mand, you'll have to check if it has an alias.

const mandName = "testmand" // This should be the user's input.
const mand = client.mands.get(mandName) || client.aliases.get(mandName); // This will return the mand and you can proceed by running the execute method.

fs.readdir(`./mands/`, (error, files) => {
    if (error) {return console.log("Error while trying to get the mmands.");};
    files.forEach(file => {
        const mand = require(`./mands/${file}`);
        const mandName = file.split(".")[0];

        client.mands.set(mandName, mand);

        if (mand.aliases) {
            mand.aliases.forEach(alias => {
                client.aliases.set(alias, mand);
            });
        };
    });
});
