In this blog, we will delve into the latest features and updates introduced by the node.js team. Whether you are optimizing workflow or enhancing app functionality, keep reading to stay ahead. And learn how you can elevate your development process!

• Watch Mode Is Stable 

With the latest version of Node.js, manually restarting your server after every code change is a thing of the past. Now, the server automatically restarts whenever modifications are made, significantly reducing downtime and streamlining the development process. This feature is especially beneficial for developers who frequently update their applications, offering a more efficient workflow and saving valuable time. The result? A smoother, more productive development experience.

• V8 Engine Upgrade to Version 12.4

Node.js 22 introduces significant improvements to the V8 engine with its 12.4 update. This release includes powerful new features like `set` methods, `Array.fromAsync`, WebAssembly Garbage Collection, and iterator helpers. These additions provide developers with advanced tools to boost application performance and efficiency.

• WebSocket Enabled Globally by Default

In Node.js 22, WebSocket functionality is now enabled by default under the experimental WebSocket flag. This update simplifies the connection process between clients and servers, eliminating the need for external dependencies that were required in earlier versions. Compared to previous versions, users can now leverage WebSockets more easily without having to manually install additional libraries.

• Require() Now Supports Synchronous ESM

Node.js 22 introduced an important enhancement with its support for ECMAScript Modules (ESM). Unlike commonJS, which has been the standard JavaScript module system in Node.js, ESM offers a more modern approach to handling modules. The latest version allows require ( ) to support synchronous imports of ESM modules using the –experimental – require – module flag.

For developers looking to take advantage of this feature, consider integrating it into your next Node.js project. Hire a skilled Node.js developer to explore this update and streamline your codebase. 

• Running Package.json Scripts 

A new experimental feature has been introduced in the latest version of Node.js. This feature allows you to execute scripts from the package.json file using the CLI flag node –run <script-name>. Additionally, support for node-run tests has been added, enabling test commands to be run directly from package.json scripts.

• Maglev Compiler

With the latest V8 Maglev compiler now enabled by default on supported architectures, short-lived CLI programs experience a significant boost in performance. Positioned between Sparkplug and Turbofan, it optimizes efficiency and streamlines execution. By integrating this compiler into your workflow, you can unlock faster development cycles and enhanced application performance. 

• Enhanced AbortSignal Creation Performance 

The latest version brings significant improvements to the creation process of AbortSignal, optimizing its performance. This enhancement leads to faster execution, benefiting functionalities such as test runners and fetch operations.
