Some Exceptional Features of Node.js 14
AsyncLocalStorage Feature
This is also called as continuation local storage. Node developers have been working on APIs to utilize context across asynchronous calls over a number of releases. This allows data storage throughout the lifetime of an online request.
Though you may find other npm modules that provide the same performance, using different packages comprehensively was very hard. Because of this, it was determined that an API must be given.
Diagnostic Report Experimental Feature Added in Node.js 14
In Node.js 14 this stable feature is added which was not there in Node.js 12. While using Node.js, this step is important for the continuous work inside the project for improvement and make the diagnostic available. This exceptional feature helps you to create a report on-demand during a particular event occur. This report comprises useful data to assist diagnose issues in app development integrating unwanted errors, high CPU usage, memory leaks, slow functionality, crashes, and more.
As a constant feature, there will be one less command-line option required to enable Diagnostic reports and it must be simpler for users to allow it in production environments.
Changes to Stream API
Improvement in consistency of the stream’s APIs, to streamline behaviours and eradicate ambiguities across the parts of Node.js core. This feature integrates several modifications labelled as Semantic Versioning, major in the Node.js Streams application.
V8 Engine Upgraded to Version 8.1
JavaScript Engine’s new version will provide performance enhancements and a few new features as follows:
Eradicating Experimental Module Warning
Despite the need to integrate the experimental-modules flag was removed in Version 13, running EcmaScript Modules in Node.js would still give an outcome as a warning ‘Experimental Warning: The ESM module loader is experimental.’
This warning is no more needed in Node.js 14 while using ESM in Node.js. Users require to be attentive while using this ESM feature in a production environment. In Node.js, it is believed that the Node.js will be stable soon as the ESM app is still experimental.
