Working with Databases in Express.js

This tutorial focuses on integrating databases with Express.js applications. Depending on the database you choose (e.g., MongoDB, MySQL, PostgreSQL), you’ll learn how to connect your Express server to the database, perform CRUD (Create, Read, Update, Delete) operations, and handle data validation and error handling. You’ll typically see examples using Object-Relational Mappers (ORMs) like Sequelize for SQL databases or ODMs (Object Data Mappers) like Mongoose for MongoDB.
