How to export variable in another file on discord.js?

To export a variable in another file in a Node.js application using discord.js, you can create a new file and define the variable in that file. Then, you can export the variable using the module.exports syntax.

Here is an example of how you can export a variable in a separate file in a discord.js application:

1. Create a new file and define the variable:

1
2
3
4
5
6
7

// config.js

const prefix = '!';

module.exports = {
  prefix
};

1. In your main file (e.g., index.js), require the file and access the exported variable:

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

// index.js

const Discord = require('discord.js');
const config = require('./config');

const client = new Discord.Client();

client.on('message', message => {
  if (message.content.startsWith(config.prefix)) {
    // Your code here
  }
});

client.login('YOUR_BOT_TOKEN');

In this example, the variable prefix is defined in the config.js file and exported using module.exports. In the index.js file, the variable is required and used to check if a message starts with the defined prefix.

By organizing your code in this way, you can separate concerns and make your code more modular and easier to maintain.
