4 min readDec 7, 2022

What is Node.js?

Node.js is a portable, quick, and effective JavaScript runtime environment for desktop apps and backend services. Developers may construct server-side scripts and command-line tools without leaving their browser thanks to its free nature. Numerous operating systems, including Windows, Linux, Unix, and Mac OS X, support Node.js. Future functionality of an app may be influenced by a number of factors, including performance and efficiency as well as ease of development, depending on the languages, tools, and platforms used. It makes use of an incredibly effective event-driven I/O mechanism that makes it possible to build scalable network applications.

For clients all across the world, develop Node.js solutions that are quick, scalable, and feature-rich in real time.

Node Js is one of the highly preferred frameworks for application development. This Newsletter will provide all the required information on and reasons to choose Node 18

1st Feature: Native Node.js 18 Fetch API

Lastly, v18 includes native Node.js fetch functionality. This is a standard web API for making network requests via HTTP or other protocols. Previously, it was not supported by default in Node.js. Since JavaScript is used in such countless regions, this is awesome information for the whole environment.

2nd Feature : watch

Your application will restart automatically when an imported file is changed using watch. similar to nodemon. Additionally, you can specify which path should be observed by using watch-path. Additionally, when used in REPL (read–eval–print loop) mode, these flags cannot be combined with — check, eval, interactive, or any other option. It simply cannot work. You can now start watching your files without installing anything by using the Node Watch index on the name of your file.

3rd Feature: OpenSSL 3 Support

OpenSSL is an open-source implementation of the SSL and TLS communication security protocols, among other things. The brand-new FIPS (Federal Information Processing Standards) module is one of OpenSSL 3.0’s most important features. For the purpose of regulating the use of cryptography in the public sector, the US government has established the FIPS standard.

4th Feature: The node for experiments: test

The Node: The test module makes it easier to create JavaScript tests that send results to TAP (Test Anything Protocol) in the format that you expect. A lot of people use the TAP output, which makes it easier to use. Although this test runner is still in development and is not intended to take the place of other complete alternatives like Jest or Mocha, it does offer a quick way to run a test suite without requiring any additional third-party libraries. Subtests, test skipping, callback tests, and other features are all supported by the test runner.

5th Feature: Core Modules with only a prefix

A new approach that makes use of a “node” to “import” modules: prefix, which immediately indicates that the modules come from the core of Node.js

6th Feature: API for Experimental Web Streams

A collection of streams APIs is a Web Streams API. It allows JavaScript to programmatically access and process data streams received over the network, which is also experimental. As a result, the global scope now includes Stream APIs. The data packets would be sent in readable and writeable streams thanks to this. Methods available are as follows, ReadableStream

ReadableStreamDefaultReader
ReadableStreamBYOBReader
ReadableStreamBYOBRequest
ReadableByteStreamController
ReadableStreamDefaultController
TransformStream
TransformStreamDefaultController
WritableStream
WritableStreamDefaultWriter
WritableStreamDefaultController

7th Feature: Additional Global APIs

The global scope of the Node v18 upgrade exposes the following APIs: Broad cast Channel and the Blob.

8th Feature: Version 10.1 of V8

The V8 engine of the Chromium open-source browser is used to run Node.js. As part of the most recent Chromium 101 update, this engine has been upgraded to version 10.1. New array methods for locating an array’s last element and index. The findLast and findLastIndex array methods are now available. Support for internationalization: Intl. Locale and the functions intl.supportedValuesOf enhancing the performance of private class methods and class fields. The v8.serialize function’s data format has changed (it is no longer compatible with earlier versions of Node.js). Keep an eye on this area.
