Built a mobile app using full stack development services to monitor air quality
Our client manufactures smart bands to monitor air quality parameters. The data processing performance of their smart band was inadequate. Our front-end full stack developers deployed a mobile solution for them.
Real-time alerts:
The mobile application now gets real-time data from the smart band.
Insights:
The users can check the air quality index (AQI-generated) insights based on collected data.
Assessment:
It facilitates in assessing impacts caused by poor air quality on public health.
Node.js 21 vs. Node.js 22: Is it time to upgrade?
With each version of Node.js introducing meaningful changes, it’s natural to ask whether updating to Node.js 22 is worth it? To assist you in making this decision, the following section provides a quick overview comparing Node.js 21 and Node.js 22 — detailing the key differences and why this upgrade might be beneficial for your projects.

Key updates in Node.js 22 features
Upgraded V8 engine and the Maglev compiler
Node.js 22 features an updated V8 engine, now version 12.4.254.14, which brings several enhancements, including WebAssembly Garbage Collection Array, new fromAsync, Set methods, and iterator helpers.
In addition, Node.js 22 introduces the V8 Maglev compiler, a just-in-time (JIT) compiler now activated by default, on compatible systems. Positioned between the Turbofan and Sparkplug compilers, Maglev optimizes the performance of short-term CLI programs, providing a notable boost in efficiency for command-line applications.

Support for importing ESM Graphs with require()
A noteworthy addition in Node.js 22 is the ability to import entire ECMAScript module (ESM) graphs using require(). Under the experimental require module, synchronous ESM graphs are now supported. For this to work, the modules must be defined as ES modules in the package.json file with “type”: “module” or by using an .mjs extension, and they must be fully synchronous. This feature streamlines modular JavaScript usage, allowing for efficient, synchronous imports without the need for complex workarounds.
Native WebSocket support
Node.js 22 brings native, browser-compatible WebSocket functionality enabled by default. Previously, developers had to rely on browser-compatible features, but this update simplifies real-time communication and eliminates the need for external WebSocket dependencies, creating a smoother experience for those building web applications that require live data streaming.
glob and globSync functions
The Node.js fs module now includes glob and globSync functions for advanced file pattern matching. These additions allow developers to efficiently find and match file paths according to predefined patterns, enhancing the management and manipulation of file systems in Node.js applications.
Enhanced add-on APIs and environment variable handling
With Node.js 22, developers have access to a comprehensive suite of tools and APIs, including WebSocket, argument parsers, and test runner. These tools enhance the core functionality and eliminate the need for extra components. You also get a text styling API (util.inspect.colors) which offers versatility in text presentation. Environment variable handling has also been streamlined, as developers can now use the — env-file command line option. They can also run commands like util.parseEnv and process.loadEnvFile to manage environment variables more intuitively.
Deprecations in util
Node.js 22 refines its handling of deprecated APIs in the util module. It follows a three-stage deprecation process — 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 to identify and transition from obsolete APIs, ensuring smoother application performance and compatibility with future versions.
Direct execution of package.json scripts
One of Node.js 22’s useful new features is the ability to run scripts directly from package.json using the command line. The new node-run <script-in-package-json> command makes it easier for developers to execute tasks defined within package.json, adding convenience and reducing the need for additional configurations.
Stabilized Watch Mode Command Line
The latest version of Watch Mode introduces enhancements such as:
These options improve the efficiency of the development process by enabling applications to automatically reboot whenever monitored files are modified.
Improved stream performance
Node.js 22 brings optimized stream handling with an increased default high watermark from 16 KiB to 64 KiB, leading to faster stream performance. This update benefits the fetch() API, AbortSignal handling, and the test runner, delivering more responsive applications with minimal memory trade-offs.
