Express.js, one of the most widely used web frameworks in the Node.js ecosystem, is undergoing a major transformation. Once considered stable but stagnant, Express is now being revitalized with a clear governance model, a renewed focus on performance, and active collaboration from organizations like NodeSource.

JSConf North America 2025 brought together the brightest minds in the JavaScript ecosystem: from maintainers and contributors to companies driving innovation across runtimes, frameworks, and platforms. For NodeSource, this year’s event was especially meaningful, filled with major announcements, community recognition, and deep discussions about the future of JavaScript. Here are some of our biggest highlights from the week.

Imagine your Node.js app is like a super-fast sports car. The "loader" is its transmission — that crucial part that gets the engine's power to the wheels, making everything run smoothly. If that transmission starts acting up, your speedy app will just sputter and stop. So, it's simple: a good loader means your app flies, a bad one means it's stuck in neutral. In this post, we'll explore how to improve your Node.js app's performance with its loader. But first, what exactly is this loader thing?

We’re excited to announce that NodeSource has joined the OpenJS Foundation’s Ecosystem Sustainability Program (ESP), a strategic partnership designed to sustain the health and reliability of the JavaScript ecosystem. Through the ESP, NodeSource will help provide security support for organizations running older, unsupported versions of Node.js, giving teams more time and flexibility to transition to newer releases while maintaining a secure posture.

Node.js 22 has entered into Long-Term Support (LTS) phase, a critical milestone that signals its stability and readiness for enterprise-level deployment. This release represents a significant push toward dependency elimination, core performance optimization, and enhanced developer experience.

Performance monitoring for Node.js has always been about two things: collecting the right telemetry and turning that telemetry into fast, confident action. With applications growing more distributed and expectations for reliability and speed rising, traditional dashboards and manual triage are no longer enough. For organizations running Node.js at scale, identifying performance bottlenecks, memory leaks, or CPU spikes can be complex and time-consuming.

Over the years, Node.js developers have relied on countless npm packages to fill gaps in the platform. From HTTP utilities to file system helpers, the ecosystem has always been one of Node’s greatest strengths. But as Node.js continues to evolve, many features that once required third-party packages are now built into the runtime itself. This shift reduces dependency bloat, improves security, and makes applications easier to maintain.

Browser automation with JavaScript is more powerful than ever. And if you're just starting out, using the selenium webdriver npm package is one of the most flexible ways to write and run your own automated browser scripts. Whether you're testing a login flow or building a web scraper, Selenium WebDriver helps you take control of the browser automatically. Add in NPM, and now you have a fast setup, easy dependency management and the full support of the Node.js ecosystem.

Node.js has moved beyond being a developer favorite, it’s a cornerstone of the digital economy. Today, it powers tens of millions of applications globally, and it underpins mission-critical systems at companies like Netflix, PayPal, Uber, and NASA. The foundation of this success is its asynchronous, event-driven architecture, designed to handle thousands of concurrent connections efficiently. From e-commerce platforms to video calls to real-time analytics, Node.js enables responsiveness at scale.

We’re excited to announce the release of N|Solid Runtime v6.0.0, the latest evolution of our Node.js runtime and monitoring platform. This release delivers major upgrades to performance monitoring, SaaS connectivity, and Node.js compatibility, ensuring that teams running business-critical applications get the insights, reliability, and efficiency they need at scale.
