Comparing Deno and Node.js: Choosing the Best JavaScript Server-Side Framework

With the advent of modern technology and changing trends, there is a significant increase in the demand for server-side JavaScript frameworks. Node.js is one of the most popular frameworks that allow developers to build server-side applications with JavaScript.

According to the Stack Overflow Developer Survey 2021, JavaScript remains the most popular programming language for the eighth year in a row, with 67.8% of developers using it.

However, Deno is a relatively new framework that has been gaining popularity in recent years. In this blog, we will discuss the features and quick comparison between Deno vs. Node.js.

Features of Deno:

Deno is a secure and modern runtime environment for JavaScript and TypeScript that allows developers to build server-side applications. It was developed by Ryan Dahl, the creator of Node.js, and released in 2018. Deno provides several features that make it stand out from other server-side frameworks. Some of the notable features of Deno are:

  1. Security:

    Deno is a secure runtime environment that provides a secure sandbox for running code. It allows developers to execute code in a secure environment without any need for additional configuration.

  2. Typescript support:

    Deno provides built-in support for TypeScript, which is a superset of JavaScript. TypeScript allows developers to write code with more robust type checking and helps in reducing the number of bugs in the code.

  3. ES6 modules:

    Deno provides support for ES6 modules, which is the standard way of organizing code in JavaScript. It allows developers to write modular code that is easy to maintain and scale.

  4. Standard library:

    Deno provides a standard library that includes several built-in modules for common tasks such as HTTP, testing, and file handling.

Features of Node.js:

Node.js is a popular server-side JavaScript framework that has been around since 2009. It provides several features that make it an excellent choice for building server-side applications. Some of the notable features of Node.js are:

  1. Large community:

    Node.js has a large and active community that contributes to its development and provides support to developers.

  2. Performance:

    Node.js provides excellent performance and scalability for building high-performance applications. It uses an event-driven architecture that allows it to handle a large number of concurrent connections.

  3. NPM:

    Node.js provides a powerful package manager called NPM that allows developers to install and manage third-party packages easily.

  4. Cross-platform:

    Node.js is cross-platform and can run on different operating systems, including Windows, macOS, and Linux.

Quick Comparison between Deno vs. Node.js:

  1. Security:

    Deno provides better security than Node.js as it runs code in a secure sandbox without any additional configuration.

  2. Typescript support:

    Both Deno and Node.js provide support for TypeScript, which is a superset of JavaScript.

  3. ES6 modules:

    Deno provides better support for ES6 modules than Node.js. Node.js requires additional configuration to use ES6 modules.

  4. Standard library:

    Deno provides a more comprehensive standard library than Node.js.

  5. Large community:

    Node.js has a larger and more active community than Deno.

  6. Performance:

    Node.js provides better performance and scalability than Deno due to its event-driven architecture.

  7. NPM:

    Node.js provides a more robust package manager than Deno.


In conclusion, both Deno and Node.js provide excellent features for building server-side applications. Deno provides better security and support for ES6 modules, while Node.js provides better performance and a larger community.
