To connect MySQL to Discord.js, you will need to use a MySQL client library such as mysql2 to interact with your MySQL database. Here are the steps to connect MySQL to Discord.js:

1. Install the mysql2 library by running the following command in your terminal:

1

npm install mysql2

1. Require the mysql2 library in your Discord.js bot file:

1

const mysql = require('mysql2');

1. Create a connection to your MySQL database using the following code:

 1
 2
 3
 4
 5

 8

10
11
12

const connection = mysql.createConnection({
  host: 'your_mysql_host',
  user: 'your_mysql_user',
  database: 'your_mysql_database',
  password: 'your_mysql_password'
});

connection.connect(err => {
  if (err) {
    console.error('Error connecting to MySQL database: ' + err.stack);
    return;
  }
  console.log('Connected to MySQL database as thread id: ' + connection.threadId);
});

Replace your_mysql_host, your_mysql_user, your_mysql_database, and your_mysql_password with your MySQL database information.

1. You can now query your MySQL database using the connection.query() method. Here is an example of querying data from a table:

1

connection.query('SELECT * FROM your_table', (err, results) => {
  if (err) {
    console.error('Error querying MySQL database: ' + err.stack);
    return;
  }
  console.log(results);
});

Replace your_table with the name of the table that you want to query data from.

1. Remember to close the MySQL connection when you are done using it:

1

connection.end(err => {
  if (err) {
    console.error('Error closing MySQL connection: ' + err.stack);
    return;
  }
  console.log('MySQL connection closed');
});

These are the basic steps to connect MySQL to Discord.js. You can now use MySQL queries in your Discord.js bot to store and retrieve data from your MySQL database.
