How to prevent SQL injection attacks in Node.js

SQL injection attacks occur when malicious users inject their own SQL code into database queries, potentially leading to data breaches and other security issues. To prevent these attacks, developers can use placeholders in query strings instead of variable interpolation, validate user input to ensure it conforms to expected formats, allowlisting specific valid inputs, and avoid allowing multiple statements. By taking these steps, developers can protect their applications against SQL injection attacks and maintain the integrity and security of their databases.
