  • NodeJs 18: The new features and improvements

    As mentioned already, NodeJs 18 is replacing the previous version, NodeJs 17. While the previous version offered optimal performance, the latest one has better functionalities and features. So, why go for NodeJs 18?

    • The primary reason to upgrade to Node 18 is the V8 engine 10.1. It is the highlight of this version.
    • Class fields and private class methods are here to offer better performance.
    • Improvement in Intl.Locale API.

    If you learn and become an expert with these features, organizations will prefer you when they hire a NodeJs expert. So, it is essential for the developers to get a hold of these features for a better chance in the market.

    That said, there is something you must know about NodeJs 18 before executing. During the initial six months of release, NodeJs will be available as the current release. But in October 2022, it will convert into Long Term Support version. Hence, it will offer support until April 2025.

Now, moving on to the features of NodeJs 18:

  1. Default enabled Global Fetch

    You can expect a default global fetch API with NodeJs 18. Remember, it is still in the experimental or testing phase. The implementation of API is likely to be spec-complaint. Also, it is based on undici inspired by node-fetch. However, the API will remain in the experimental stage until contributors verify it.

    In addition to this, you can get hands-on global exposure to Web Stream APIs. Like global fetch API, they are also experimental. Here are some web stream APIs you can get in NodeJs 18.

    • ReadableStreamDefaultReader
    • ReadableStreamBYOBRequest
    • ReadableStreamBYOBReader
    • ReadableStream
    • TransformStream
    • ReadableStreamDefaultController
    • ReadableByteStreamController
    • TransformStreamDefaultController
    • WritableStreamDefaultWriter
    • WritableStream
    • WritableStreamDefaultController
    • CountQueuingStrategy
    • ByteLengthQueuingStrategy
    • TextDecoderStream
    • TextEncoderStream
    • DecompressionStream
    • CompressionStream
  2. Node:test Module

    Another exciting feature of NodeJs 18 is a tester runner module, “node:test.” It is also experimental. With this module, you can ensure the streamlined creation of JavaScript test reports that come in TAP format. The best way to access this test report is by using: import test from ‘node:test’;

  3. V8 10.1

    The highlight of the NodeJs 18 is its V8 10.1. It is an updated version of the previous V8 in NodeJs 17.9.0. Plus, it is part of chromium 101. Below are the latest features that make V8 10.1 better than other versions.

    • Intl.Locale API enhancements.
    • Availability of array methods like findLast() and findLastIndex().
    • Intl.supportedValuesOf function.
    • Class fields and private class methods ensure better performance.
  4. V8 snapshot

    Thanks to the V8 startup snapshot, NodeJs 18 can help users to create a NodeJs binary. So, make sure you use – node-snapshot-main flag.

  5. Default HTTP timeouts

    You can use the server.headersTimeout to set HTTP header time to 60 seconds. However, in NodeJs 18, you can set the default time to 5 minutes.

  6. Updates in toolchain and compiler

    NodeJs always had prebuilt binaries for various platforms. And whenever it updates, toolchains are improved if needed. So, the trend continues in NodeJs 18 also. The following are the prebuilt binaries for NodeJs.

    • Developed on Red Hat Expertise Linux 8 (RHEL), Linux prebuilt libraries work well with Linux distributions on Glibc 2.28.
    • There are improvements in the minimum supported architecture of AIX. It has upgraded from 7 to 8.
    • If you want to use macOS prebuilt libraries, you need macOS 10.15.

    Note:* Currently, prebuilt libraries are not available for 32-bit Windows because of some issues. However, in the coming future, this problem might resolve.

  7. Better support for AbortSignal and AbortController

    When it comes to AbortSignal and AbortController, NodeJs is familiar with these functions. But in the latest version, we can see improved support for these. The updated AbortSingnal.Timeout() allows you to terminate an HTTP request hassle-free when using fetch.

  8. Improvements in ECMAScript modules

    Although ECMAScript module support is not new to NodeJs, each version brings improvements. And NodeJs 18 is not an exception. Here are some upgrades, such as:

    • If you want to use esm JSON modules, you no longer need a command line flag.
    • It offers support for JSON Import Assertions (experimental).
    • It adds support for HTTPS and HTTP imports, which is also experimental.
