Discord.js bot: Prefix change command not working after file split

Hey folks, I’m running into a problem with my Discord bot. I recently separated my code into different files, and now the prefix change command fails. I initially had all my code in one file, which worked perfectly, but after splitting it, the command stopped functioning. Below is my updated main file:

const Discord = require('discord.js');
const botConfig = require('./bot-settings.json');
const botClient = new Discord.Client();
const fs = require('fs');

botClient.on('message', msg => {
  if (msg.author.bot) return;
  if (msg.content.indexOf(botConfig.cmdPrefix) !== 0) return;

  const cmdArgs = msg.content.split(/\s+/g);
  const cmdName = cmdArgs.shift().slice(botConfig.cmdPrefix.length).toLowerCase();

  try {
    let cmdFile = require(`./commands/${cmdName}.js`);
    cmdFile.run(botClient, msg, cmdArgs);
  } catch (err) {
    console.error(err);
  }
});

botClient.login(botConfig.secretToken);

And here is my command file for changing the prefix:

exports.run = (botClient, msg, cmdArgs) => {
  const adminRole = msg.guild.roles.find('name', 'Bot Admin');
  if (!adminRole) return console.log('Bot Admin role not found');

  if (!msg.member.roles.has(adminRole.id))
    return msg.reply('You need Bot Admin role to use this');

  let newPrefix = msg.content.split(' ').slice(1, 2)[0];
  botConfig.cmdPrefix = newPrefix;
  fs.writeFile('./bot-settings.json', JSON.stringify(botConfig), (err) => console.error);
}

When I try to change the prefix, I encounter this error:
ReferenceError: botConfig is not defined

Does anyone know what might be causing this error and how I can resolve it?

The issue you’re encountering is due to scope. When you split your code, botConfig became inaccessible in your command file. To resolve this, you need to either pass botConfig as a parameter or require it directly in your command file.

I’d recommend requiring it directly for simplicity. Modify your command file like this:

const botConfig = require('../bot-settings.json');

exports.run = (botClient, msg, cmdArgs) => {
    // Your existing code here
}

Make sure the path to bot-settings.json is correct relative to your command file’s location. This approach maintains your current main file structure while giving your command file access to botConfig.

Additionally, consider using a database for frequently changing settings like prefixes. It’s more robust for concurrent operations and prevents potential file write conflicts.

I faced a similar issue when I split my bot’s code into separate files. The problem here is that botConfig is not accessible in your command file. To fix this, you need to pass botConfig as a parameter to your command function.

Update your main file to include botConfig when calling the command:

let cmdFile = require(`./commands/${cmdName}.js`);
cmdFile.run(botClient, msg, cmdArgs, botConfig);

Then modify your command file to accept botConfig:

exports.run = (botClient, msg, cmdArgs, botConfig) => {
  // Your existing code here
}

This should resolve the ReferenceError. Remember to update all your command files to accept this new parameter. Also, consider using a database instead of a JSON file for storing settings that change frequently, as it’s more reliable and efficient for concurrent operations.

yo guys, i think i kno whats up. ur botConfig aint visible in ur command file. ez fix tho - just import it at the top of ur command file:

const botConfig = require('../bot-settings.json');

make sure the path is right. should work now. gl m8!
