So i want my bot on discord to have custom replies for example:

user: Hi

bot: Hello

user: ping

bot: pong

I want to make my bot do this but i'm using an event handler for all the commands i'm using and I don't want to use If(message.content ==... message.channel.send ".." in the messagecreate.js or the index.js file because I'm planning to use multiple messages like so and I'd like my code to be relatively clean and organized

so if there is any way I can move the 'if' statements to another messagereplies.js file and run it from there, please let me know

This is my messagecreat.js file

require('dotenv').config();
    module.exports = async (Discord, client, message) => {
        const prefix = (process.env.PREFIX);
    
        if (!message.content.startsWith(prefix) || message.author.bot) return;
    
        const args = message.content.slice(prefix.length).split(/ +/);
        const cmd = args.shift().toLowerCase();
        const command = client.commands.get(cmd) || client.commands.find(a => a.aliases && a.aliases.includes(cmd));
    
        if (command) command.execute(client, message, args, Discord);

and this is my event handler

const fs = require('fs');

module.exports = (client, Discord) => {
    const load_dir = (dirs) => {
        const event_files = fs.readdirSync(`./events/${dirs}`).filter(file => file.endsWith('.js'))

        for (const file of event_files) {
            const event = require(`../events/${dirs}/${file}`);
            const event_name = file.split('.')[0];
            client.on(event_name, event.bind(null, Discord, client))
        }
    }

    ['client', 'guild'].forEach(e => load_dir(e));
}

Basically I just want a block in the messagecreate.js file or event_handler.js file that executes another file in another folder if a message is sent
