Let’s take a quick look at some of the most notable new additions and features in version 18 of Node.js.

1. Global fetch allowed by design

When you see “global fetch enabled by default,” you should understand that this implies the computer will automatically get information from the internet whenever a user opens a document or website that needs it. This implies that when you browse a site, you won’t have to wait for all of the contents of the page to load since the computer has already retrieved them earlier, which will contribute to speedier surfing overall. Using the Fetch API to send an HTTP request is now simpler thanks to the introduction of a notable new feature in Node.js 18, which was released recently.

2. Update of V8 JavaScript Engine to 10.1

The most recent upgrade to the V8 JavaScript Engine, version 10.1, includes many enhancements to both the functionality and the speed of the program. One of the most significant improvements is the addition of the Sparkplug bytecode interpreter, which helps to execute JavaScript code more quickly. This is one of the most prominent advancements. Furthermore, version 10.1 has several enhancements and new language features, such as support for the dynamic import () syntax and an optional chaining operator. The conversion of JavaScript code into native machine code is made significantly simpler by the V8 engine.

3. OpenSSL

OpenSSL is a library of open-source software. It is used by a large number of people. The most recent version of this software library, known as OpenSSL 3.0, has improved functionality and speed, as well as increased interoperability with other security protocols. The most important modification that was made to OpenSSL 3.0 was the implementation of an entirely new secure memory distribution scheme. Memory leaks and buffer overflows are both avoided thanks to this technology, which also serves to make it more resistant to potential security risks. Support for the most recent version of the TLS protocol, version 1.3, which offers improved safety and connection speeds, is another significant upgrade that has been implemented.

4. The Core Test Runner Module

Any task involving the creation of software must include the Core Test Runner Module. It is the responsibility of this component to carry out all of the tests that have been designed by the developers to guarantee that the program satisfies the necessary criteria and requirements. Because of the module’s adaptable nature, software engineers can construct tests in a range of programming languages, such as Java, Python, and C#, amongst others. In addition to this, it gives users a variety of choices for performing tests, such as the ability to run many tests simultaneously and execute tests with a variety of various settings.

5. Advent of WebRTC

The development of a technology known as WebRTC has made previously inaccessible activities such as video calling, online gaming, and live streaming far simpler to utilize. The potential of this technology and the influence it may have on the development of web apps in the future is intriguing to contemplate. Web Stream APIs in Node.js are also helpful for processing real-time data, such as information received from sensors or other sources.

6. Enhanced security

Your sensitive information may be better protected, and unauthorized users will have a harder time getting into their accounts thanks to the increased security settings. It is always a good idea to examine and update your security settings regularly to make sure that you are taking benefit of all of the available precautions to keep your information secure. The default configurations of Node.js have been updated to incorporate more stringent Content Security Policy (CSP) settings, which protect websites from cross-site scripting (XSS) attacks.

7. Other APIS

Developers can incorporate strong features, capabilities, and data from third-party sources into their applications by using Application Programming Interfaces (APIs), which are the basic elements of contemporary software development. In addition to the widely used application programming interfaces (APIs), such as Google Maps, Facebook, Twitter, and Amazon Web Services, there are a great number of additional APIs that have a worldwide reach and may provide developers with new options.

8. Toolchain and Compiler Modernisations

The process of developing software programs often requires the use of several different programming tools that are together referred to as a toolchain. Regular updates of these tools are required to maintain compatibility with the most recent technologies and feature sets. By upgrading their toolchains and compilers, software developers may help create apps that are more effective and have a higher level of performance. The most recent updates often contain bug fixes, security patches, and improved interaction with more recent versions of operating systems.
