Preventing SQL injection attacks in Node.js

SQL injection is a malicious attack where nefarious SQL code is injected into a system, exposing sensitive information, corrupting or deleting data, and sometimes, granting unauthorized access to attackers. Addressing this threat is difficult, and it emphasizes the need to ensure the security of your Node.js applications.

In this article, you'll learn more about why SQL injection attacks pose a significant threat and how to shield your Node.js applications against them.

To better understand how SQL injection works, let's quickly create a vulnerable app using Node.js, Express, and a PostgreSQL database. The application takes user input from a form, constructs a SQL query, and executes it against the database to fetch some data.

Start by downloading and installing Node.js on your machine. Node.js is the runtime environment that executes your JavaScript code server-side.
