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.

The real estate industry today is no longer defined by physical site visits or paper-heavy transactions, rather, it’s now powered by digital ecosystems that simplify, accelerate, and personalize every property experience. From AI-driven property recommendations and virtual tours to secure digital escrow, rental management, and instant documentation, technology is reshaping how people discover, buy, sell, and manage real estate.

Healthcare organizations using Cerner Millennium (Oracle Health) struggle with integrating data trapped in complex databases and proprietary systems. Building custom APIs or integrations can be time-consuming, costly, and risky — especially when patient privacy and compliance are on the line.

The age of agentic AI introduces unprecedented risks. In the rapidly evolving landscape of artificial intelligence, agentic AI is emerging as a transformative force, capable of autonomous decision-making, learning, and interaction. These sophisticated AI systems are poised to revolutionize industries and daily life. Conversely, these same capabilities can be exploited by attackers to launch highly effective and scalable cyberattacks. The advancement of AI brings a critical imperative.

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?

The global retail landscape has undergone a massive digital revolution. With online shopping now accounting for a growing share of global sales, the e-commerce market is expected to surpass $8 trillion by 2027. From small retailers to global enterprises, every brand is racing to deliver seamless, secure, and personalized digital shopping experiences, and eCommerce apps are at the center of this transformation.

As we pass through the years, the electric vehicle (EV) industry has become all about driving smarter, faster, and more connected than ever before. With the rapid adoption of EVs, expanding charging networks, and evolving consumer expectations, the need for advanced digital ecosystems has become critical. From charging station locators to battery analytics, fleet management, and EV-sharing platforms, every interaction now relies on intelligent, data-driven technology.

Drone technology — also known as unmanned aerial vehicle (UAV) and unmanned aircraft system (UAS) technology — is expanding rapidly across commercial, industrial, and defense sectors. As these systems become more complex, they increasingly rely on sophisticated software for aerial embedded systems.

During this week’s AWS us-east-1 outage, Ably maintained full service continuity with no customer impact. This was our multi-region architecture working exactly as designed; error rates were negligibly low and unchanged throughout. Any additional round trip latency was limited to 12ms, which is below the typical variance in any client-to-endpoint connection, and well below our 40–50ms global median; this is imperceptible to users and below monitoring thresholds.
