Deno vs Node.js: What are the differences?

Introduction

Deno and Node.js are both JavaScript runtime environments that allow developers to run JavaScript code outside the web browser. While they have several similarities, there are some key differences between the two platforms that distinguish them from each other.

1. Deno: Secure by default. Deno is designed with security in mind, aiming to provide a secure runtime environment for executing JavaScript and TypeScript code. It has built-in restrictions that prevent access to the file system, network, and other potential security risks by default. Any permissions required by a script need to be explicitly granted, improving the overall security of Deno applications.

2. Node.js: Legacy support and package ecosystem. Node.js has been around for a longer time and has a larger user base, which means it has a vast ecosystem of packages and libraries available through the Node Package Manager (NPM). This extensive support for libraries and modules makes it easier for developers to find and utilize existing code. Node.js is also more backward-compatible as it allows running older JavaScript versions, while Deno follows the latest ECMAScript standards.

3. Deno: No package manager required. Deno allows developers to import modules directly from URLs or file system paths. It does not require a separate package manager like NPM to manage dependencies, making it easier to use and reducing potential compatibility issues. Deno resolves dependencies based on URLs and caches them on the local machine, ensuring consistent results across different environments.

4. Node.js: Event-driven architecture. Node.js follows an event-driven architecture, leveraging its non-blocking I/O operations to handle multiple concurrent requests efficiently. Its event loop mechanism allows developers to build highly scalable applications, making it a popular choice for server-side applications and microservices with high traffic and real-time requirements.

5. Deno: Built-in TypeScript support. Deno natively supports TypeScript, a superset of JavaScript that adds strong typing and other advanced features. This means that developers can write their applications in TypeScript without any additional configuration or transpilation steps. Deno can directly execute TypeScript code, providing better support for type-checking and improved overall code quality.

6. Node.js: Extensive community and corporate support. Node.js benefits from a large and active community of developers and contributors. It is backed by several large corporations, including IBM, Microsoft, and SAP, who actively contribute to its development and provide ongoing support. This level of community and corporate involvement ensures a steady stream of updates, bug fixes, and new features, making Node.js a reliable and well-supported platform.

In Summary, Deno and Node.js have several key differences. Deno provides a secure-by-default runtime environment, does not require a package manager, has built-in TypeScript support, and is designed to be compatible with the latest JavaScript standards. On the other hand, Node.js benefits from its vast ecosystem of packages and libraries, event-driven architecture for scalability, and extensive community and corporate support.

I am a front-end guy and in the last month I've been trynig to be learn backend in python. I think python is a great language to but when i start to learn django I didn't like it because everythong is already done for you, you dont need to do much make it works and I like coding thing that take me time. I've been thinking about switching to another programing language or just learn Node js and stick with it. I need to know if django is that easy.

Node.js

Laravel

PHP

I want to create a video sharing service like Youtube, which users can use to upload and watch videos. I prefer to use Vue.js for front-end. What do you suggest for the back-end? @{Node.js}|tool:1011| or @{Laravel}|tool:992| ( @{PHP}|tool:991| ) I need a good performance with high speed, and the most important thing is the ability to handle user's requests if the site's traffic increases. I want to create an algorithm that users who watch others videos earn points (randomly but in clear context) If you have anything else to improve, please let me know. For eg: If you prefer React to Vue.js. Thanks in advance

Hi Team

I want your suggestions in order for me to decide which stack is suitable for the below-mentioned requirement.

Currently, I am considering building it in Wordpress (Starting with prebuilt plugins and develop on it)

But I am skeptical, so I am considering Laravel.

And recently I found one very good solution built in Angular, Node and MySQL

Here are the high-level goals I am trying to achieve:

The system has 3 modules

Multi-Vendor e-commerce Market Place
Peer to peer Selling of used items
Listing/ Directory kind of portal for the service industry

What are some alternatives to Node.js, Deno?

Rails

Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.

Django

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

Laravel
