Performance and efficiency aren’t just technical concerns, they’re business-critical. For companies running Node.js applications, hidden inefficiencies can quietly drive up costs, slow down innovation, and increase risk. N|Solid transforms the way businesses manage and optimize their Node.js applications.

At NodeSource, we live and breathe Node.js and are passionate about performance and security. We understand that for developers and platform teams, managing the security and compliance of dependencies is a mission-critical task. However, the tools designed to help can sometimes become part of the problem. Today, we’re proud to introduce NodeSource Certified Modules v3 (NCM v3): a complete rearchitecture of our module scanning and observability engine.

If you've ever tried building an API with plain JavaScript and found yourself drowning in bugs, weird errors, or spaghetti code, yo, you're not alone. That’s why so many devs are leveling up their backend game by mixing Node.js with TypeScript. It's like going from playing Minecraft in creative mode to building actual skyscrapers: more control, better structure, and way less chaos.

Error handling might not be the most exciting aspect of web development, but it's arguably one of the most critical. When building Express applications, how you manage errors can make the difference between a robust, production-ready system and one that crumbles under real-world conditions. In this article, we'll examine Express' default error handling behavior and learn how to customize it for different scenarios.

Are you still running Node.js 12, 14, or even older versions in production? If so, you’re facing a serious challenge: these versions have reached End-of-Life (EOL) and no longer receive official updates or security patches. For many organizations, especially those operating on legacy environments like RHEL 7 or Ubuntu 18.04, upgrading to the latest Node.js version isn’t always feasible.

At NodeSource, we’ve always been committed to making the Node.js experience secure, stable, and production-ready for teams around the world. Today, we're announcing a key change to how we serve and support our Node.js binary distributions, and it comes with something new: Extended Support.

Observability isn’t a luxury, it’s a necessity. But for teams managing large Node.js applications, getting real-time visibility into performance, memory usage, async behavior, and security can be a complex and risky endeavor, especially if it means modifying your production code. That’s where N|Solid by NodeSource changes the game. Imagine getting deep, real-time insights into your Node.js applications without touching a single line of your business logic.

Node.js is known for its non-blocking, event-driven architecture, making it great for handling I/O-bound tasks like web requests and file operations. But when it comes to CPU-intensive tasks, things get tricky. Because Node.js runs JavaScript in a single-threaded environment, heavy computations can block the event loop and degrade application performance. That’s where Worker Threads come in.

Relational databases rely on SQL, or Structured Query Language, as the standard way to control and interact with their stored data. In the Node.js ecosystem, Sequelize is a prominent Object-Relational Mapping(ORM) library that bridges the gap between Node.js apps and SQL databases, enabling you to interact with your data using familiar JavaScript idioms. This article will guide you through using Sequelize to connect to databases, run queries, and handle results within your Node.js projects.

Performance and stress testing are two popular testing methodologies. They focus on determining how an application behaves under regular and unexpectedly high traffic, respectively. These tests are essential for assessing a system's robustness and scalability, particularly in applications with fluctuating traffic like Node.js backends. In this article, you'll learn about stress and performance testing, why they're important, the best tools available, and how to use them in Node. Let's dive in!
