How can I integrate a database with my Express application?

You can integrate a database with your Express app by using an ORM like Sequelize or a database driver like Mongoose for MongoDB.

What are the steps to set up Sequelize with my Express app?

First, install Sequelize and the database driver. Then, configure Sequelize with your database credentials and define your models.

Can you show me a sample code for connecting to a MySQL database?

Sure! Here's a basic example:

const { Sequelize } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql'
});

sequelize.authenticate()
  .then(() => console.log('Connection has been established successfully.'))
  .catch(err => console.error('Unable to connect to the database:', err));
