Node.js 14 released with improved diagnostics!


June 17, 2020


Node.js 14

Node.js is an open-source platform with cross-platform back-end technology to build server-side network web applications. It makes use of event-driven and non-blocking mode for the app development with a fast back-end. Node.js is very renowned in the modern era as it offers a great set of opportunities to developers and enhances the effectiveness of the engineering teams.

One of the best aspects of Node.js is that it is highly renowned among developers as it offers a JavaScript runtime environment for application development.  The current version of Node.js has been recently launched that provides enhanced capabilities to help developers with improved diagnostics as well as a revised JavaScript engine to ensure better performance.

Long Term Support (LTS) strategy

The Node.js follows the Long Term Support (LTS) approach and the developers need to know that the current Node.js 14 will not be production-ready till it reaches LTS that is expected in October 2020. The date is likely to shift due to the current pandemic situation. Till then, developers are encouraged to report issues that they find while working on Node.js 14 so that all the major bugs and issues can get easily resolved before the LTS version gets completed. In regard to this, Node.js 12 is the most recommended version for use in production applications until it’s Node.js 14 reaches the LTS version.

New Features:

Experimental Async. Local Storage API

The new Node.js 14 enhances internationalization support with complete ICU (International Components for Unicode) data. Also, the new version slows users to run and support applications in native locales. Another important addition in Node.js 14 is its experimental support for Async. Local Storage that builds an asynchronous state with promise chains and callbacks. The addition of this new API gathers data throughout the life span of a web request or other asynchronous operations. In other programming languages, async local storage is analogous to thread-local storage.


The new Node.js 14 has the inclusion of a number of changes that are marked as SemVer major in the implementation of the Node.js stream. These changes are envisioned to enhance consistency across streams APIs to confiscate ambiguity and streamline behaviors across different parts of Node.js core. For instance, http.OutgoingMessage is analogous to stream. Writable and net. Socket behaves just like a stream. Duplex. One of the major changes is that the option of`autoDestroy` is now defaulted to true, which makes the stream always call `_destroy` after ending. However, it is quite impossible that these SemVer major changes are going to impact most applications, as they only alter edge cases, if you majorly depend on Streams then it would be really good to test as Node.js 14 is the latest release and it will be ready when Node.js 14 becomes LTS in October 2020.

Experimental Web Assembly System Interface

For Node.js, packages are written in web assembly that brings the opportunity for better performance and cross-platform support for certain use cases. The new Node.js release includes an experimental implementation of the WASI (Web Assembly System Interface) to help support these use cases. Web assembly is an emerging approach that allows application code to run in various environments without modification. Also, the experimental WASM interface is a kind of enabler that enables WASM to attain access to OS type resources like the file system and sockets.

Node.js 14 Release Cycle

There is always a strict development cycle that Node.js diligently follows for its releases, with other multiple branches in different phases of maturity at any given point of time. For instance, Node.js 14’s initial phase was broadcasted in the month of April that was contemplated as its current phase.

Final Words

According to the LTS approach, Node.js is going to be in the current phase for the next 6 months. As discussed above, LTS is the point where the release is considered to be completely production-ready. Henceforth, Node.js 14 is all set to become an active LTS release on October 2020 and is likely to be supported till April 2023.
