What are the new features in Node.js 16?

In the latest Node v16.0.0 released recently, the documentation defines that in every 6 months the Node.js releases a new version.

There are 2 categories of Node.js version:

Unsupported in which all the odd number versions of node.js are included and LTS mode in which the version of even numbers are included. In LTS said all the critical bugs are said to be solved upto 30 months.

Features of Node.js 16:

In this blog you will get all the information new features of Node.js 16 and what’s new after the upgradation of Node.js version

They are as follows:

Version 9 of V8 JavaScript engine

Among consecutive releases V8 included various range of functions that helped in the overall upgradation of the performance. The V8 JavaScript engine permits JavaScript to run throughout various platforms so developers have no fear of coding.

With V8 model 9, you get considerable and precise capabilities for ordinary expressions. You can allow this through the usage of the flag /d in everyday expressions.

Updated support:

Like most latest releases, this latest launch improved the most miniature supported stages for the equipment and systems required to construct Node.js. For instance, right here are a few examples that replace or amend to the minimal help,

• GCC model for Linux
• AIX systems to 8.3
• XCode model to 11

Another fascinating stuff includes the work being executed to build on an assist for the ultra-modern Apple M1 architecture. Processors of Apple Silicon believe that the performance is improved. it is believed that this can enhance the overall performance characteristic of the brand new Mac hardware.

Consequently, Node.js will run basically at the Apple M1 in place of using the Rosetta emulation layer. Developers are energetic in configuring or putting in the M1 machines to check or create the binaries running natively and collating for M1. native M1 support is provided in Node.js 16.

Version 8 of N-API:

Node.js 16 is constantly stepping in advance to make it smooth to build, generate and assist native modules known as add-ons. Node.js 16 brings alongside the NODE-API v8 support.

Sealing objects like- napi_object_seal

Freezing objects like- napi_object_freeze

Type tagging objects such as- napi_type_tag_object/napi_check_object_type_tag

The Promise APIs:

To secure promise-primarily based APIs a crucial step has been taken. On an excellent note, now you could do the following.

Input:

Output:

V16 advertises the timers’ guarantees API. This precise API gives JavaScript timer features that first of all deliver back native guarantees. Functions like setTimeout() normally are given a callback. However, this may emerge as unmanageable while you operate it with the modern-day asynchronous code.

Async Local Storage APIs

The main focus should be on determination and observing the problem to assist and help customers so that they can quickly identify and manage their issues.

Additionally, the idea of AsyncLocalStorage API seems to be a lot easier, reliable, and speedy to turn solid than the essential Async Hooks.

It is a primary step to provide a built-in set of APIs utilized by numerous programs, including the OpenTelemetry, to help the tracing factor of Observability within side the applications of Node.js.

Let us now look into some codes using the AsyncLocalStorage to see the benefits that it brings with it.

Input:

Output:

To conclude upgradation is very much necessary and so we all should upgrade and use node.js 16 features. In this version some of the features of node 15 have also been included so if you want to upgrade from node 15 to the latest version of node.js 16 then you should look for a top-notch development company that will help you keep a safe backup and stay up-to-date.
