Node.js quickly earned much recognition from leading organizations and was widely used by industry leaders in their production environments. Node.js has a large number of users and it is one of the biggest communities in the development world.
With Deno’s launch, people started assuming that Deno will replace Node.js and Deno is a replacement for Node.js. To clear this confusion, we will be talking about Deno vs node and how Deno is a Node.js alternative and not a replacement.
Deno vs Node: Difference Between Deno And Node.js
Before we jump to the comparison, let’s start with a quick overview of each. Both are runtime environments created by the same software engineer.
What Is Deno?
First and foremost, Deno is not a branch of Node.js.
Deno aims to provide a secure V8 runtime engine with TypeScript as its base because of its accuracy. It also promises to simplify modules and build systems and provide a secure and productive scripting environment.
What Is Node Js?
It offers asynchronous I/O and event-driven architecture that make Node.js super fast and a perfect fit for scalable, real-time web applications.
With event-driven architecture and single-threaded design of Node.js, programmers can build highly-concurrent applications and fast web servers.
Let’s talk about the difference between Deno And Node.js.
Deno vs Node: How Deno Is Different From Node?
One of the key objectives of Deno is to provide users with security that Node.js lacks. Deno is secured by default. This means a program run with Deno has no file, network, or environment access unless specified. Deno requires programmers to give access to an executing script through command-line flags or prompt runtime permission same as browser implements.
Deno restricts file system and network access by default to run code in a secure sandbox.
Node.js allows access to network and file systems, making them vulnerable and open to exposure or some security concerns. When you work with Node.js, there are many such security issues you need to handle to prevent your app from security breaches.
Packages in Deno are linked directly to the URL, unlike Node’s npm. Deno fetches local or remote dependencies using URLs, similar to browsers.
Npm is the default package manager for Node.js. It is used to install and manage public and private third-party packages. This online database of packages is called the npm registry.
Now, Node.js developers have access to this async/await syntax but they also have to manage backward compatibility through APIs.
First Class TypeScript Support:
Node.js has one of the largest, most vibrant, and innovative open-source communities in the world. It is built and maintained by the community.
A large number of developers use Node.js and power thousands of apps. And Deno is the new player in this space. It is in evolving phase and growing.

Will Deno Replace Node.js?
This most-discussed topic has a simple answer, No.
Deno is created by the same creator of Node.js. This is true and it is also true that it overcomes the design mistakes of Node.js.
But, it won’t replace Node.js.
If we see the current landscape of software development, Node.js has been around since 2009 and Deno is like a baby compared to the vast and strong Node.js community.
Developers and open-source contributors are still getting comfortable with this new runtime environment. Certainly, it has huge potential as it overcomes some serious challenges of Node.js like security, modules, central repository system, and callbacks.
Deno will take time to grow. The number of libraries, frameworks, packages, and resources is too small to consider when you compare Deno with Node.js. Given that, Node.js is mature, evolved, and used by a large number of users, replacement by Deno is quite impossible.
We have to wait till Deno’s full potential is realized and accepted by the developer community. Till then, we can try Deno, share feedback, and experiment with its powerful features like security and package management.
We see a bright future and growth for Deno which is a very interesting project started by Ryan Dahl.
