The release of Node.js 24 is another piece of good news in the history of server-side JavaScript development. Every release comes with new features that make it faster and more modern, with improved APIs and a simplified developer experience. As JavaScript continues to evolve rapidly, Node.js will remain aligned with the latest ECMAScript standards and web platform functionality.
The new Node.js 24 features are focused on speed, usability similar to a native browser, modern diagnostics, and enhanced asynchronous context management. The developers may now enjoy better performance in regard to runtime, better V8 support, more compatible modules, and more common-sense debugging features. We will now examine the highlights of the Node.js 24 release and its implications for the developers.
The following are the key updates of the Node.js 24 release notes:
- Improved performance and a reduced memory footprint of various core modules.
- New V8 engine with new JavaScript and improved execution speed.
- Improved AsyncLocalStorage to better track context in an asynchronous operation.
- Native Fetch API, allowing for easier HTTP requests and a browser-like experience.
- Enhance the web streams API to conduct operations related to streaming more effectively.
- Enhanced ECMAScript Modules (ESu M) compatibility makes module usage easier.
- Diagnostics and debugging tools were optimised to monitor performance and trace.
These improvements make Node.js 24 more efficient and developer-friendly.
B] Key Performance and Engine Updates
1. Performance Improvements
Optimisation of overall runtime performance is one of the priorities in Node.js 24. The garbage collection routines and internal event loop have been optimised to minimise memory waste.
The main modules, such as fs and the networking layer, have been optimised for faster execution and contain low latency. Applications developed using Node.js 24 should have higher throughput in cases of heavy loads; therefore, they are more applicable in real-time applications, microservices, and high-performance APIs. These Node.js 24 performance upgrades are directly translated into improved server speed and a better user experience.
2. V8 Engine Update
Node.js 24 features the latest update of the V8 engine, providing developers with the latest JavaScript language features and improved performance. The new V8 engine improves just-in-time compilation and optimises the common code paths.
Additionally, it supports the most recent ECMAScript features, allowing modern syntax and APIs to be utilised without the need for transpilers. This enhances code maintainability and the productivity of the developer.
3. AsyncLocalStorage Improvements
The other major improvement in Node.js 24 is an improved behaviour of AsyncLocalStorage. In the past, it might have been difficult to maintain the context of asynchronous operations.
Context propagation is now more predictable and reliable, particularly in more complex async pipes like in Express.js or in custom middleware with the updated implementation. These Node.js 24 AsyncLocalStorage improvements facilitate tracking requests, correlating logs, and maintaining state within distributed tracing.

C] New and Improved APIs
1. Node.js 24 Fetch API Support
One of the most anticipated updates is the inclusion of the native Fetch API in the 24th version of Node.js. The Fetch API is now directly accessible to developers in the runtime, as opposed to them relying on external packages, such as node-fetch or axios.
This enables the browser and server code to share the HTTP logic effortlessly. Regardless of whether you call the REST API or process the JSON information, the update simplifies the code and enhances its consistency. The Node.js 24 Fetch API implementation makes Node similar to browser JavaScript.
2. Web Streams API
The Web Streams API has been enhanced to be stronger and more diverse in Node.js 24. These are the improvements of the Node.js 24 Web Streams API that can effectively process large data transfer and complex streaming pipelines.
This is particularly useful for file uploads, video processing, and real-time data feeds. The stream interface is also unified, which simplifies the process of turning the applications of Node.js into cloud services and modern frameworks.
3. ECMAScript Module Support
Historically, Node.js had a problem with module handling because both CommonJS and ESM were coexisting. Node.js ECMAScript module support means that it will not pose a major problem with compatibility issues.
It is easier to import and export and has more reliability in interoperability with CommonJS. The codebases of older versions can be shifted to the modern syntax of ES modules without breaking them. This makes the structuring of projects easier and facilitates the development of Node.js in line with industry trends.
D) Diagnostics and Debugging Tools
The Node.js 24 diagnostics and debugging tools are also enhanced greatly. New profiling tools enable developers to obtain more detailed information about CPU usage, memory usage, and asynchronous operations.
Stack traces may be enhanced to simplify error tracing, particularly in complicated async-heavy applications. In-built debugging is more compatible with the latest IDEs and observability environments. The result of these upgrades is that teams can track performance more efficiently, debug with increased speed, and be confident of production reliability.
Conclusion
Node.js 24 makes Node.js a suitable and convenient way to create scalable applications; it is powerful, modern, and flexible. This version provides support for cleaner code and more efficient workflows. An added emphasis is placed on Node.js 24 performance improvements, V8 engine improvements, improved asynchronous context handling, and support of modern API features such as Fetch and Web Streams.
The developers enjoy the ECMAScript module support that is easier, has better diagnostics, and is less complex to debug. Regardless of what you develop, APIs, real-time systems, or even large-scale backend platforms, Node.js 24 offers improvements that are meaningful and can be used to make the development process smoother and the performance of the applications better.
