The Node.js is the most popular JavaScript framework that is acclaimed and admired by major web development agencies. The new version of Node.js – Node.js 10 is gaining popularity day by day. Therefore, exploring Node.js 10 Features has become vital.

Previously, web developers have to rely on multiple coding languages and platforms for backend and frontend web development.

However, thanks to the Inception of the Node.js, developers don’t have to go for different options for different purposes.

A couple of months back, the developers of Node.js have upgraded the framework and released Node.js Version 10, which has exciting and scalable features to improve the coding experience for developers.

Let’s understand what the top Features Of Node.js 10 that you need to know to improve the user experience of your web app is.

1. Better Error Handling

Error Handling in Node.JS

Errors can be frustrating when you are working with Node.js code. Because Node.js not been descriptive while showing the exact error and suggesting how to resolve them.

Previously Node.js was only giving string messages in the console, so you have to match it with your source code to identify where the actual problem lies.

With the introduction of Version 10, error handling has become smoother. Now, they have got more standardized and developers a more sophisticated approach to cope with an error.

The Node JS Development Companies are excited about this feature. It will surely help them all in the long run. So, make sure you also take this aspect into consideration.

Now, all errors thrown by the platform has the error message as well, so you don’t have to keep matching the strings to identify the error’s source. Let’s dive deep into Features Of Node.js 10.

Also, don’t forget to add below strings in your code whenever you migrate to the new version of the Node.js.

try {

// do stuff

} catch (err) {

if (err.code === 'ERR_ERROR_CODE') {

// handle specific error

} else {

// general error handler



2. ESM Modules

The support for a model set Node.js 10 improves significantly. Although it is not the complete support by the Node.js developers, the efforts by the community predict the better support for ESM modules in the next time.

In JavaScript, it is all about managing and maintaining variables throughout the code. JavaScript, you define variables assign them values and use value as variables for other functions.

In JavaScript, you have got the scope of these variables that determines the effectiveness of the variable. So for different functions, you don’t have to worry about variable which belongs to a different scope.

But sharing this variable across function is your requirement ITI solved by modulus which helps you, group, relevant features and variable in a single module to be an application process of a particular scope.

But the improved yes module filesystem revolutionized the whole function of executing and reading the code. Node.js system has started developing its own ESM module system to give complete control and freedom to the developers to build robust code.

In 2015, the Node.js introduced it with ESMA Script Modules. So, with the evolution of Node.js 10 Features, the adaptation has evolved, and implementation is a lot smoother.

3. N-API Is No Longer An Experimental Feature

Before version 8, the native modules have always been a pain point in Node.js whenever you are upgrading or switching versions.

Before version 8, developers have to manage API stability to V8 or NAN APIs. These layers were resourceful but did not provide stability in API execution and integration.

Moreover, real developer Shivpuri compiles Java code Whenever And you measure release. The reason behind recompiling the code is to match it with upgraded layers and versions of the node.js.

So, Node.js did introduce N-API as an experimental feature. However, Node.js 10, and API is no longer an innovative feature of the Node.js. It is a fully functional API layer that stands above v8 and NAN and provides better stability in APIs.

Moreover, synchronization with leading virtual machines with the help of N-API would be a lot easier now. Previously the Node.js was supported by the Google Chrome browser only.

Now, with N-API’s introduction with version 10, the porting of Node.js application to different VMs would become more accessible and user-friendly.

4. HTTP2 As a Stable Feature


One of the best news for the Node.js developer is that HTTP 2 is no longer an experimental feature now. Today, HTTP 2 in the Node.js is now a fully-functional feature.

They did introduce HTTP 2 as an experimental in version 8.4. Now, the feature is stabilized and available to be implemented in real-time scenarios.

HTTP 2 is a binary protocol that is responsible for TCP multiplexing. Thanks to the existence of HTTP 2, TCP handshake will be done only once.

Now, this means that the server can reuse this already made handshake for further communication purposes. They can send and receive requests multiple times and don’t have to do TCP handshake every time.

For the beginners who don’t know the significance of TCP handshake, it is a process of establishing a connection between host, client, or the server.

It is a three-step procedure where both the parties send and receive a couple of signals to verify and connect with each other. This sending and receiving initial signals are known as TCP handshake.

TCP handshake is done before the actual data and messages transferred between two parties.

Although TCP handshake is a time-consuming procedure, and it has to be done every time for communication. While doing the TCP handshake, a lot of processing time at the server end is for this job. But not from now since we have HTTP 2.

HTTP 2 also supports server push features. Usually, whenever the website asks for the HTML file from the server, the server responds with the file which it loads at the user’s end.

Now to make it look appealing and also apply the format, the website realizes that it also requires stylesheets and JavaScript files from the server. So, it again requests for these additional files to it loads at the user’s end.

Thanks to the server push feature, the server will automatically send relevant style sheets and JavaScript files along with HTML files so that webpages can be loaded quickly.

This way, the website doesn’t have to communicate regularly for file transfer and requests.

5. Trace Events For Better Diagnostic

In the new version of Node.js, the developer added features of tracing events to give a complete understanding of everything that is going on with the source code.

Trace events will improve the visibility of developers of their code. The trace events will enable the developer to resolve bugs and run time errors efficiently.

With the help of this feature, developers can turn on specific events of the code. These events will enable the users to understand whenever special events occur while diagnosing the code.

This feature will save a lot of time and resources of users since they no longer have to depend on testers and users to report any bug.

They would be allowed to create alerts and events which will be fixed by the trace events feature to let users know about a specific function. You can also use Docker For Node.js Development.

6. Node 10 Has NPM Version 6

Node 10 Has NPM Version 6

Node.js has recently upgraded the NPM version from 5.7 to 6. the updated version would undoubtedly provide more robustness and enhanced abilities to secure and execute code.

Now with Node.js version 10, NPM version 6 will be automatically shopped. So, users don’t have to download and upgrades to version 6 manually. It will automatically upgrade the version of NPM and enable smarter and more dynamic coding experience for developers.

Compared to 5.7, and version 6 has more stability and an agile environment for developers to build scalable node.js applications.

Compared to other NPM versions, NPM 6 is 17 times faster. The security enhancements which you have to enable in previous versions separately, are built-in in NPM 6.

NPM 6 also supports a command ‘npm audit’ which will check all the dependencies and hierarchies which are insecure in the code.

So, if you find something is not secure or needs improvement, you can quickly replace those dependencies or upgrade them to ensure the safety of your node.js project.

In NPM 6, the webhooks management has also taken a paradigm shift, and developers can build their webhooks using NPM 6 more easily and quickly compared to what they could do in the previous versions.

7. Enhanced Cipher With OpenSSL 1.1.0




Cryptography and decipher abilities is essential for web applications to ensure secure communication channels between server and web browsers.

With the evolution of technology and the internet, cyber threat is also becoming promising with each passing day since hackers are becoming proactive and skilled enough to break into a system to access confidential data of the website.

That said, developers and network administrators are also working tirelessly to strengthen the security of their service and improving navigation and cryptographic abilities of their websites.

With the introduction of node.js version 10, people will get OpenSSL 1.1.0 that will support highly complex and reliable ChaCha 20 cipher.

For authentication and verification, this version will use a Poly1305 authenticator to ensure the most reliable browsing experience to users.

8. Upgraded V8 Engine For Compiling Scripts

Those of you who are familiar with JavaScript coding language would agree that a fully functional script has a ton of functions, variables, and answers to internal scripts that one has to compile and execute correctly to execute a function of a web application.

Node.js has a V8 engine that smartly compasses everything for maximum success of the JavaScript code. One of the major Cons of Node.js Development was not able to handle a heavy load. This will be a thing of past now.!

Well, with Node.js version 10, the V8 engine version is upgraded to 6.6, which is more robust and capable of executing complex script efficiently and takes a lot less time.

The V8 engine version 6.6 comes with Chromium browser and Chrome Version 66.

So, long story short, this new version of the V8 engine has the power to reduce the time and resources required to parse and compile JavaScript code by up to 40%. This one of the best Node.js 10 Features.

Since there is an optimization of the time and resources by 40%, the developers can improve the user experience of their products.

Now, customers can enjoy improved accessibility to the web apps, which takes the basis on the Node.js framework. That’s why Node.js In Web App Development is the prime choice.

9. Shipping Of Fs Functions With Promises

Shipping Of File System

Accessing the file system is an essential element of a Node.js application. So, Node.js 10 will be shipping with experimental ‘fs’ functions with promises to make the task easy for developers.

Previously function util.promisify() was in use to convert these functions which were driven by asynchronous actions through callbacks.

So, there is no need for the extra step which developers had to perform in the new version of Node.js.

10. Detailed Reflection Of Functions

The JavaScript functions are also utilized as objects too — this is the power of JavaScript and its nature of insane portability.

Before Version 10, the toString(); the method was returning the method name. However, now it can return the whole first line instantaneously.

Check out the snippet below to understand that the return value extends all kinds of comments.

function /* demo */ whatsTheLocation()





11. Emission Of Targeted Tracing

There have been several tracing parameters that the new version of Node.js omits. You can further enable or disable trace objects at your will with just a few lines of code.

const trace_events = require('trace_events');

const t1 = trace_events.createTracing({

categories: ['node', 'v8']


const t2 = trace_events.createTracing({

categories: ['node.perf', 'node']

Conclusion – What Lies Ahead For Node.js?

Node JS is one of the most renowned frameworks that can help the programmers by allowing them to ensure relevant user experience in their products.

Node.js is built over the years to make itself one of the most favorite JavaScript frameworks that can do almost everything that a developer wishes.

With the introduction of Node 10, this JavaScript framework pushes the boundaries of its problem-solving approach and enables one of the robust coding environments to resolve errors, create a stunning app, and improve the lives of humans.

So far, the Node has been famous for it’s particular odd/even update cycle. Node.js 10 Features will have the span of October 2018 to April 2021, and that means, the span of Node 10 is significantly larger than the usual.

Version 10 is an even number upgrade of the platform, and that makes it LTS. The odd numbers of the versions are more focused on experimentation.

The more version will have better stability and enhanced scalability, which would make the overall Node.js platform valuable.
