An Overview of Node.js 22
The much awaited Node.js 22 version is available now for all since 24 April 2024. With an updated V8 engine, built in WebSocket client and updated JavaScript features allows developers to build application more faster and efficient. This latest release brings in a range of exciting features and essential advancements for the Node.js development company to build application quickly. This includes the Maglev compiler, updates on running packages .json scripts, add-on APIs, and much more, improving the overall development experience.
As per the schedule, Node.js 22 will go into long-term support(LTS) IN October 2024. Until then it will function as the Current release, enabling developers to make the most of the latest version. So, now let’s explore Node.js 22 version in detail and find out the beneficial new features and latest updates. Before that, let’s go through the previous and upcoming Node.js versions, covering all the basic details about each versions!
Node.js 21 VS Node.js 22: Should I Update or Not?
After looking at the different versions of Node.js, you must be wondering why should I upgrade to Node.js version 22? Well, go through the table below and have a quick overview of the different aspects of both versions and learn why should you should update to the latest Node.js version 22.

What’s new in this update?
Updating V8 to 12.4 and V8 Maglev compiler
With this latest Node.js version you get the updated V8 engine. Now, the V8 engine has jumped to 12.4.254.14. V8 release 12.4 introduces more beneficial new features, comprising WebAssembly Garbage Collection Array, fromAsync, Set methods, and iterator helpers.
Moreover, the V8 Maglev compiler, which is the new JIT compiler, is now activated by default on supported architectures. The Maglev compiler sits between the Turbofan and Sparkplug compilers. It allows developers to improve the performance of short-term CLI programs, leading to increased efficiency.
Importing ESM Graphs Using require()
Node.js version 22 has brought the ability to import an entire ECMAScript module (ESM) graph using require(). This release includes require() support for synchronous ESM graphs under the experimental-require-model section. When leveraging the experimental-require-model, the ECMAScript module loaded by require() must meet requirements stated below: it should be
- Explicitly marked as an ES module with a “type”: “module” field in the closest package.json or have a .mjs extension.
- Fully synchronous (contains no top-level await).
Using require() will load the requested module as an ES Module and return the module namespace object directly. This operation is similar to dynamic import() but is run synchronously.
This feature enables Node. js development service provider to function more efficiently with modular JavaScript without a complicated fix.
Web Sockets
Node.js 22 offers browser compatible WebSocket that will be enabled by default. Before then, developers had to enable browser-compatible features using an experimental websocket. Now, these features of the browser-compatible implementation are enabled automatically as a default without needing external dependencies.
Glob and globsync
The node: fs module incorporates advanced features, including the glob and globSync functions, to effectively match file patterns. Functions for matching file patterns. These updates help the Node.js development service provider find and match file paths as per the predefined patterns. This feature improves the ability to manage and manipulate file systems within Node.js applications.
Add-on APIs and Better Defining of Environment Variables
With this new release, you get a wide range of tools and APIs that improve core functions and eliminate the need for additional components. These APIs include a WebSocket, argument parser, and test runner. Besides that, you also get a Text Styling API that streamlines text formatting utilizing util.inspect.colors, offering much-needed versatility in text presentation.
Additionally, Version 22 offers noteworthy improvements in describing file environment variables. You can hire a Node.js developer and enable this functionality by using the—env-file command-line option. Furthermore, developers can run commands such as util.parseEnv and process.loadEnvFile to make managing it easier. It reduces the friction and improves the overall development experience.
Deprecations in util
Node.js 22 offers developers a systematic approach to manage obsolete APIs. It involves a systematic depreciation process with three stages: documentation-only, runtime, and end-of-life. However, many util APIs were discontinued during runtime in Node.js 22. Developers are advised to run their applications with the—throw-deprecation flag for already depreciated APIs since it offers smooth transition.
When updating to Node.js 22, analyzing and substituting depreciated APIs can help your applications work more efficiently and compatibly.
Deploy package .json scripts
This preliminary feature by Node.js 22 enables the Node.js development company to execute scripts directly from the packages.json. It uses the command line interface (CLI) called node-run <script-in-package-json>. Moreover, it utilizes the node-run test to implement the test command defined explicitly within the package.json scripts.
Steady Watch Model Command Line
The latest revision has made the Watch Mode Command Line more steady. This also includes options like:
-Watch
-Watch- Path
-Watch- preserve-output
These latest features simplifies the web application development process by rebooting automatically whenever they modify the watched files during development.
Enhanced Stream performance
Node.js 22 offers improved stream performance compared to Node.js 21.Node.js 22 serves streams more effectively. The default high watermark has been increased from 16 KiB to 65 KiB. This feature is acclaimed by more effective Abortsignal creation and faster fetch() API and test runner operations. All of this ultimately leads to high-performing applications, obviously with slightly high memory usage. Also, the developers who work in a memory-sensitive environment would be required to set- setaDefaultHighWaterMark.
What should be your Next Step?
Node.js 22 is one of the most important and beneficial version update. It marks an essential advancement for JavaScript runtime environments, with the updated V8 engine, magvel compiler, and built-in web socket. With improved performance through importing ESM Graphs using require(), glob, and globsync and enhanced stream performance empower Node.js development company in the USA to build faster, more robust, and more efficient applications.
Node.js 22 offers compelling features that make it an exceptional choice for your next project, whether you’re streamlining your development workflow or building real-time functionalities. Upgrade to Node.js 22, a valuable transition that allows you to stay ahead the latest advancement in JavaScript development.
