Deno vs Node JS – Which Is Better

Deno is one of the popular additions to the JavaScript ecosystem and Node.js is the most widely used runtime environment. It is obvious to get confused with the selection of a suitable development environment for your business applications. Are you looking to make a quick decision on the selection of a JavaScript framework? The blog highlights the best details for differentiation. 

Node.js is regarded as the default JavaScript framework for new-day development needs, but Deno is delivering modern advantages to your developmental projects. It is assumed that Deno will replace node.js and thus the clash between the two is bound to happen! Consult with a Deno development company able to provide top assistance for developing suitable apps. 

To clear all the confusion, we will discuss the facts related to Deno vs Node.js performance and the difference between them. Let’s get started!

Deno: A Quick Overview

Deno is the modern-day framework created by ‘Ryan Dahl’ and the same person was instrumental in building Node.js. If you desire secured runtime then Deno is the preferred option today over Node. It is rich with a powerful package management system and proven legacy libraries.

The framework is also used as per web platform standards and filled with in-built developmental tools. Deno can run a TypeScript file without the requirement of added configurations. It is working as the shell around the JavaScript engine and it includes the TypeScript compiler.

The top aim of the JavaScript platform is to address the different aspects of Node.js and streamlines the server-side scripting needs. Deno is built with Rust language and provides a safe runtime environment. The question of Node js vs deno will further raise with addition of new features and the basic understanding will ensure proven results. 

Node.js: A Quick Overview

Node.js supports the V8 engine and ensures back-end JavaScript development. It is a cross-platform JavaScript platform useful for the development of servers & apps. The platform has a callback function and thus handles the non-blocking I/O calls easily. It has a larger customer base and is used for the development of suitable networking tools.

It is not limited to JavaScript and also uses the type of language that transpires to JavaScript. The utility of Node comes from the secured package library and was developed as the scalable alternative to Apache HTTP Server.

Node is the most suitable development platform ensuring the use of modular systems with the assistance of third-party codes. It is also used to develop server-side apps and is easily available to JavaScript users.

Comparing the Deno vs Node performance will help judge the suitable platform for application development. 

Deno vs Node.js: What is the Difference between the Two?

Primarily, Deno and Node.js are very similar – each of them offers appropriate package management, a proven system for importing the modules, and also third-party codes. But, there is a difference between both frameworks that indicates the relevant use. Looking to analyze Deno vs Node popularity for specific development tasks? 

Let us check the difference between Deno and Node.js –

Package Management

The integration of packages is done instantly into the URL in Deno, and it is different from Node’s npm. The default package of Node.js is nom and is used specifically for the optimization of third-party packages relevant to development.

Deno is featuring JavaScript features filled with async functions and also offers abstractions referred to as ‘Futures’. It is easy for developers to utilize different APIs in the JavaScript environment.

Single Executable File

Deno is available with built-in tools and is shipped as a single executable file with no dependency. The list of tools included in Deno is – debugger (–inspect, –inspect-brk), bundler (deno bundle), documentation generator (deno doc), dependency inspector (deno info), linter (deno lint), and test runner (deno test).

Deno is able to update itself with ‘deno upgrade’ or ‘deno upgrade –version <new version>’. The version manager of Node.js is responsible for installation & updating the latest versions like ‘nvm’.

Security Framework

One of the primary goals of using Deno is to guarantee the end-users a secure developed environment, unlike the Node.js platform. Deno is much safer than other development frameworks as it limits the file systems by default.

Node.js is permitting access to file systems and thus becomes prone to security concerns. The availability of security concerns is common with Node.js development. The command-line flags in Deno are ensuring the developers provide access to the implementation of scripts. It also ensures runtime permission to the browser execution and it enables the running of safer codes to the sandbox.

Top-Rated TypeScript Assistance

TypeScript is a prolonged version of JavaScript that ensures customers deliver the right kind of data. Deno uses a TypeScript compiler using the caching technique for packaging. In Deno, it comes with a default config file and adds your own ‘deno run –c tsconfig.json [file-to-run.ts]’.

The encryption of Node.js packages is done in JavaScript and there is no such TypeScript in the development framework. 


The Deno development framework is using the ES modules standard format to package for JavaScript cod) – import package from ‘module-name’.

JavaScript does not have the module system or Node environment and uses the CommonJS standard – const package = require(‘module-name’).

Node has support for ES modules and it is vital to do the configuration of files. Deno is providing Node Compatibility Library and thus allows the use of NPM packages.

Standard Modules

Deno has the standard module and utilities to be easily edited by the core development team. The modules are tagged in simple accordance with the releases and ensure automatic linking to the master branch.

In case you want to lock a specific module version on Node.js then using the ‘lock.json’ file becomes vital for ensuring module integrity. It is vital to link across the tagged version of the packages to avoid unwanted updates or changes.

To Sum Up!

The competition between the Deno vs Node.js developmental framework will increase with time as the same developer will be using both platforms. It is preferred to use Deno for one set of developmental activities and Node.js for another. Both platforms deliver tremendous backend developmental assistance, but take the final decision based on urgent development needs.

Are you thinking of replacing Node.js with Deno? It will be hard to do the replacement and hire professionals able to provide guidance for suitable developmental tasks. Deno is not the regular upgrade of Node.js and uses specific features to do efficient development.
