How can I integrate a database with Node.js?

You can integrate a database with Node.js using libraries like Sequelize for SQL databases or Mongoose for MongoDB.

What are the steps to set up Sequelize?

First, install Sequelize and the database driver, then initialize Sequelize with your database configuration.

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'
});

What if I want to use MongoDB instead?

You can use Mongoose. First, install it, then connect like this:

const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });
