The landscape of Nodejs database integration has evolved significantly with the introduction of the built-in node:sqlite module in Nodejs v22.5.0. This native SQLite integration eliminates the need for external dependencies, offering a streamlined, efficient way to work with databases directly within your Nodejs applications.

Nodejs makes shipping features fast; sometimes too fast. In 2025, public CVE data shows SQL/NoSQL injection is still the #1 flaw in Nodejs applications, followed closely by prototype pollution and malicious dependencies. Below you’ll find runnable code, real-world fixes, and a copy-paste checklist so you can push secure code without slowing CI/CD.
Nodejs developers building applications with sensitive data face a critical challenge: how to encrypt information while maintaining query capabilities. Traditional encryption methods force developers to choose between security and functionality. MongoDB’s Queryable Encryption, introduced in version 7.0, finally breaks this deadlock by allowing encrypted fields to remain searchable.
Nodejs developers often reach for Promise.all() when handling multiple asynchronous operations. However, this seemingly innocent approach can cause serious performance issues in production environments. Understanding the limitations of Promise.all() and implementing proper batch execution strategies is crucial for building robust, scalable Nodejs applications.
Middleware is the hidden plumbing of a Nodejs and Expressjs application. It sits between the incoming request and the final route handler, letting you validate, transform, log, secure, or reject traffic before it ever reaches your business logic. When written well, middleware keeps your codebase modular, testable, and easy to reason about.
