And now Node.js is out there, and it is ready to surprise you all with its exciting and unique features. It offers plenty opportunities to the network application developer and has also come with various other improvements. Meanwhile, in October, the Node.js 8 is going to turn bigger as it will be armed with the Long Term Support with its code name ‘Carbon’. This LTS is likely to be maintained for a few years until 31st December 2019.
What Node.js 8 has in cards to offer?
To start with, it has Node.js API which will not just assist for the developers but also for the async hooks, WHATWG URK parser, zero filling buffers, JS Binding for inspector and a lot more.
Here, let’s discuss the many essential features Node.js 8 has to offer:
Quickly develop native add-ons
It comes enabled with npm 5
The presence of npm 5 is another exciting feature of Node.js 8. Since the default now option saves it, thus it can be used by the users without any trouble. Meanwhile, if there is a no npm-shrinkwrap.json, the package-lock.json gets developed automatically. You don’t have to look for the network, if there is no internet connection or it gets lost. Like, if you chose registry B, then npm 5 will install that package instead of some other one.
Info on all crucial Async Hooks API
Earlier known as AsyncWrap, Async Hooks is among the most popular features of the Node.js 8. The API helps you collect updated info on life of handle objects by structural tracing. Additionally, it allows node.js developer to control the Node.js event loop function.
Other features comprise of:
• No need of third-party library to implement readable control flow which was required with co.
• Solves the purpose of continuation-local-storage npm package, in the hub.

TurboFan and Ignition
The introduction of the TurboFan and Ignition is one of the most significant attributes of the latest version of Node.js 8. The combination of the both has been in the process of development for a few years.
The TurboFan acts as an optimizing compiler while the Ignition is known for V8 interpreter. In case of TurboFan, it uses less memory and offers quicker start-up in Node.js developed apps.
Better Buffer Security
Both the buffers, the zero filling Buffer and the new Buffer, are now added by default. However, earlier, the memory space was not initialized with zero. This led to a few security issues.
Now the new version has allowed people to secure their privacy. However, Node.js 8 users are advised to first make themselves aware of the risks factors involved in function and only after that use it to avoid the leakage of secure information. Meanwhile, there is an issue that you have to take performance hits. However, it’s better to move on to buffer.allocUnsafe ().
Implements WHATWG URL
In the new version, WHATWG URL is implemented. Earlier it was added in the Node.js 7 on experimental basis. It surely has many advantages with one being it matches with the URL implementation and API, accessible in the prominent web browsers including Google Chrome, Mozilla Firefox, and Apple’s Safari, etc. The code can be shared across various environments using the URLs.
This handy feature helps the Buffer num users to understand the app well when developing time and testing in the CI environment. The Node.js can send warnings and depreciations when the Buffer num is used.
However, take a note to not make use of Buffer() and new Buffer() constructors for security reasons. Instead, use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from().

Console is modified
Earlier when developers tried writing the console output to the underlying stream, the Node.js app use to collapse due to certain errors. But now you have Node.js 8.0 version as your savior. The errors have been rectified by repressing the issue events with the help of console process. Thus you have secure API.
These were the most vital features Node.js 8 has to offer and the ways to use them to fulfill your various requirements. It’s time to get the web development company that suits your needs well and get the updated version of Node.js.
