How do I configure connection pooling in Node.js for my database?

To configure connection pooling in Node.js, you can use libraries like mysql or pg for PostgreSQL. Would you like a code example?

Yes, please provide a code example for MySQL.

Sure! Here's a simple example using the mysql library:

const mysql = require('mysql');

const pool = mysql.createPool({
  connectionLimit: 10,
  host: 'localhost',
  user: 'yourUsername',
  password: 'yourPassword',
  database: 'yourDatabase'
});

pool.getConnection((err, connection) => {
  if (err) throw err; // not connected!
  console.log('Connected as id ' + connection.threadId);
  connection.release(); // return the connection to the pool
});

What are the benefits of using connection pooling?

Connection pooling improves performance by reusing existing connections, reducing the overhead of establishing new connections for each request.
