How Can I Connect to MySQL Databases Using Node.js?

Connecting to MySQL with Node.js

As a seasoned PHP developer transitioning to Node.js, you may be wondering how to leverage your MySQL expertise in your new environment. Here's how you can seamlessly connect to MySQL with Node.js:

1. Choose a MySQL Module

Node.js offers several modules that facilitate MySQL connectivity. Some popular options include:

• node-mysql: A simple and reliable module for MySQL interaction.
• node-mysql2: An asynchronous driver with advanced features like pipelining and prepared statements.
• node-mysql-libmysqlclient: Asynchronous bindings based on libmysqlclient.

2. Establishing a Connection

Once you've selected a module, establishing a connection to MySQL is straightforward using the following syntax:

const mysql = require('mysql');
const connection = mysql.createConnection({
  host: 'example.org',
  user: 'bob',
  password: 'secret',
});
connection.connect(function(err) {
  // Do something...
});

3. Executing Queries

Querying data in MySQL is just as simple. Here's how to insert a record using the connection.query() method:

var post = { id: 1, title: 'Hello MySQL' };
var query = connection.query('INSERT INTO posts SET ?', post, function(err, result) {
  // Handle errors or results here...
});
console.log(query.sql); // INSERT INTO posts SET `id` = 1, `title` = 'Hello MySQL'
