Exploring Node.js 24.0.0: New Features and Improvements to Know

Node JS 24.0.0 was released in May 2025, introducing major updates in performance, security, and developer experience. The latest version of Node.js marks a revolutionary update to the open-source platform, combined with a faster V8 engine, updated tooling, NPM 11, and more. 

If we check the version timeline, then it is marked as the Current stage. However, the version will officially achieve LTS (Long-Term Support) status in October 2025. Once it enters LTS, it'll receive critical bug fixes and security updates for a period of 30 months.

Let’s take a detailed look at the wealth of new features and improvements that bolster security and improve developer experience.

Node.js 24.0.0: Key Features and Improvements

Here is the breakdown of relevant updates and improvements included in the recent release of the node version. Staying up to date with these changes will help you build applications more efficiently.

V8 Engine 13.6

The recent version brings a big update, which is the upgrade to the v8 JavaScript engine version 13.6. This introduced new areas of performance optimization and new JS features.

Float16Array: This new typed array extends support for half-precision floating point numbers, beneficial for tasks requiring memory efficiency.

WebAssembly Support: Node is now more capable to run WebAssembly modules with 64-bit, improving performance for apps.

RegExp.escape(): This utility enables developers to escape regular expressions for special characters, which makes the string more safer and easier to read.

Error.isError(): A small utility that helps to identify between error instances.

These features make the node a reliable choice for programmers who want to utilize the latest JS features.

Npm 11

The newest release of Node.js includes npm version 11 that offers improved performance, enhanced security, and heavy compatibility with the latest JavaScript packages. NPM offers smarter caching and performance tweaks, which help to decrease the install times. Moreover, NMP enhances dependency resolutions for large projects that deal with dependency misery. NPM also improves compatibility with the modern ecosystem.

Enhanced Performance

The v8 improvements and Undici will boost the apps for better scalability. The notable improvements in Async operations, HTTP requests, and JSON performance will significantly deliver high-thoughtful services. The recent node versions help to execute your app faster, resulting in better utilization of resources and rapid response times. Reduced latency level contributes to a snappier user experience.

Upgraded HTTP Client

Nodej’s ultra-fast HTTP client, Undici, has upgraded to v7. This will result in improved HTTP performance, and there will be better support for the newest HTTP standard. There will be a more consistent API for programmers who want to target both the Node and browser environments.

Experimental Permission Model

The permission model of the node has matured significantly in the 24 version. It is now flagged -permission that helps to enhance the security of your app. This enables you to protect your app’s access to several system resources like file systems, network access, or while executing subprocesses.

Breaking Changes and Removals

Every major version upgrade comes with certain breaking changes that users should watch out for. So the node 24.0 version is no exception, where it brings deprecations, which include;

Node.js has cut down the support for Microsoft Visual C++ (MSVC). Now, ClangCL requires a toolchain for compiling on Windows. This shift may require a particular setup for existing programmers.

Deprecations/Removals

• The old url.parse() is deprecated; instead, utilize the WHATWG URL API.  
• Removal of deprecated tls.createSecurePair. 
• SlowBuffer is also deprecated. 
• In the child process method, the passing of args to spawn and execFile is deprecated.
• Working with Zlib classes without new is also deprecated.

Legacy API Deprecations

Several legacy APIs and constants have been deprecated or assigned for removal in the future to simplify the platform. 

What are the Important Enhancements for Developers?

URLPattern

Struggling with importing URLPattern is over, as it is now available globally. So matching URLs is being more clean and the routing is simpler.

Improved Built-in Test Runner

The built-in node:test runner module has been introduced with additional enhancements. It now provides excellent support for asynchronous testing, automatic subset handling, and prevents common issues. 

AsyncLocalStorage Improvements

AsyncLocalStorage is now set as the default to AsyncContextFrame, proffering a more efficient implementation of asynchronous context tracking.

Enhanced HTTP/2

Node 24.0.0 also introduced enhancements for HTTP/2 implementation with improved performance, better error handling, and stream management. These improvements contribute to building high-performing web servers.
