Everything You need to Know About NodeJS Version 14 Shared by Experts

There are many frameworks and programming languages available in the market, but it is hard to keep up with the changing trends in the technology. This is the reason why developers of these languages often come up with the new versions so that they can be used in the modern times and also, these new versions have everything covered which was missing in their predecessors. 

Talking about the languages and frameworks, Nodejs is one of the most popular JavaScript frameworks available for creating some amazing web solutions. It is being used across 85 countries and powers websites in more than 45 languages. Indeed Node.js is fast, powerful, and flexible. This JavaScript framework powers the front-end to make this task easy. Node.js operates on a single-thread, using non-blocking I/O calls, allowing it to support tens of thousands of concurrent connections held in the event loop. Also, this framework can be used on numerous platforms, such as Windows, Linux, Mac, OS, and UNIX. Agility, efficacy, flexibility, scalability are some of its major USPs, basis on which it has become one of the most favorable choices amongst the NodeJS developers.  

First introduced in 2009, Node.js has recently launched its version 14, which was released on the 21st of April 2020 featuring few improved diagnostics and a WebAssembly interface. According to the release schedule by GitHub, for the next six months, Node.js 14 will be the current release. It will be further promoted to LTS (Long-Term Support) in October 2020.

Nodejs has been able to prove its worth and gained momentum worldwide and 2020 is no other year hence we can see a lot happening over the next few months with version 14. 

Let’s dive into the features highlighted for this release and the most significant updates of version 14 that we can expect in 2020.

Node JS Version 14

Diagnostic Report goes Stable

In Nodejs 12, the diagnostic report was added as an experimental feature; however, in Nodejs 14, it will be launched as a stable feature. It creates a report on-demand or when particular events occur. This feature facilitate app development companies to diagnose issues in app development incorporating unwanted errors, high CPU usage, memory leaks, slow functionality, crashes, and more. It is a vital step that works inside the project and enhances the accessibility for smoother use. We can run this report in development, testing, or production. It shows a full report on where issues are occurring, thus making it easier to handle the problems. The common problems it detects are:-

  • Abnormal termination
  • Slow performance
  • Memory leaks
  • High CPU usage
  • Unexpected errors
  • Incorrect output

The command to be run is:-

node --report-uncaught-exception --report-on-signal --report-on-fatalerror app.js

V8 upgraded to V8 8.1

Every new version brings improvement in performance. This new version of the V8 JavaScript engine V8 8.1 has the following features, which makes the performance faster and uses less memory.

  • OCR Caching brings up to 18% improvement in execution time
  • Built-in functions are up to 12% faster due to new API
  • Double ? Tagged transitions deprecation brings up to 12% improvements in speed
  • Pointer compression brings up to 40% heap size reduction. This improvement is also combined with a garbage collector and speed improvements of up to 10%

Experimental Async Local Storage API

This version release brings an experimental Async Local storage API. This allows app code for running in several environments with no changes. The community of Nodejs developers has been taking a shot at APIs to help follow and oversee setting through asynchronous calls over various discharges. It is similar to thread-local storage in other languages.

Experimental Web Assembly System Interface

The version 14 release includes an experimental implementation of the Web Assembly System Interface (WASI) to help support certain use cases. The WASI class provides the WASI system call API and additional convenience methods for working with WASI-based applications. Each WASI instance represents a distinct sandbox environment. For security purposes, each WASI instance must have its command-line arguments, environment variables, and sandbox directory structure configured explicitly. It is a regular interface for creating calls to the underlying system, like the host application. 

New compiler and platform minimums

For Node.js 14, the minimum GCC level on the Linux based platforms stays at GCC 6; nevertheless, the binaries will be possibly made or released for a few platforms with GCC 8. Node.js offers pre-built binaries for several platforms. Node.js 14 version moves all of our macOS binaries to be compiled on macOS 10.15 (Catalina) with Xcode 11 to support package notarization. For Nodejs 14, we’ve bumped the minimum macOS target version to macOS 10.13 (High Sierra).


Node Streams have been updated. This release includes several changes marked as SemVer major in the Node.js Streams implementation. These changes are intended to improve consistency across the Streams APIs to remove ambiguity and streamline behaviors across the various parts of Node.js core. If you depend on Streams, you should better test the latest release Node.js 14 so that it is prepared for when Node.js becomes Long-Term Support in October 2020, and even web development companies love this new change.

Removal of Experimental Modules Warning

It is believed that the present application provides a sustained model to authoring ESM modules that create the way to Universal JavaScript. ECMAScript Modules (ESM) in Node.js results in an "Experimental Warning" while running. That warning has now been removed. Node.js 14 makes it easier to create, build, and support native modules. Node 14 comes with N-API version 6, which includes support for BigInt along with other improvements.
