Step 1: Install MySQL and MySQL module for Node.js
The first step is to install MySQL and the MySQL module for Node.js. You can install MySQL using your package manager or download it from the official website. Once MySQL is installed, you can install the MySQL module for Node.js using the following command:
npm install mysql
Step 2: Create a MySQL database and table
Before connecting Node.js with MySQL, you need to create a MySQL database and table to store data. You can use the following SQL commands to create a database and table:
Step 3: Connect Node.js with MySQL
To connect Node.js with MySQL, you need to create a connection object using the mysql module. The connection object contains the necessary information to connect to the MySQL database.
Here’s an example of how to create a connection object:
In this example, we create a connection object with the host, user, password, and database properties. We then call the
connect() method on the connection object to establish a connection to the MySQL database.
Step 4: Perform CRUD operations
Once you have established a connection to the MySQL database, you can perform CRUD (Create, Read, Update, Delete) operations on the database using Node.js.
Here’s an example of how to insert data into the users table:
In this example, we create a user object with name and email properties. We then use the
query() method on the connection object to insert the user object into the users table.
Connecting Node.js with MySQL is a straightforward process that involves installing MySQL, creating a MySQL database and table, creating a connection object using the mysql module, and performing CRUD operations on the database. Node.js provides a powerful platform for building database-driven applications, and MySQL provides a reliable and scalable database management system for storing and managing data.
