Node.js vs Vue.js

Node.js: It is a JavaScript runtime environment, which is built on Chrome's V8 JavaScript engine. It is developed by Ryan Dahl who is a Software Engineer working at Google Brain, he also developed Deno JavaScript and TypeScript runtime. Node.js is cross-platform and open-source which executes JavaScript code on the server-side, i.e. outside the web browser. Due to its single-threaded nature, it is mainly used for event-driven, non-blocking servers, a non-blocking I/O model makes it lightweight and efficient, hence it is best for data-intensive real-time applications. It is used by traditional web-sites and back-end API services. It is designed with a real-time, push-based architecture that runs across distributed devices. The HTTP (Hypertext Transfer Protocol) module provides a set of classes and functions for building an HTTP server. We use native Node like file-system, path, and URL for this basic HTTP server. Vue.js: It is an open-source progressive JavaScript framework that is mainly used for building UIs and single-page applications. It is created by Evan who was funded by the community on Patreon to develop VueJS. It is compatible with most modern technologies and because of the gentle learning curve and scalability, it gained a lot of popularity. VueJS follows the Model-View-ViewModel (MVVM) architectural pattern, where ViewModel has a 'Vue' instance and View and Model are bound by two-way data binding. It utilizes a virtual DOM and in terms of API and design Vue is easy to learn as compared with AngularJS. As the concerns of routing and state were handled in ReactJS, in the same way Vue handles it by associate libraries. Difference between Node.js and Vue.js:

Node.js	Vue.js
Node.js is a cross-platform and open-source back-end framework that executes JavaScript code on the server-side.	Vue.js is a structural, open-source JavaScript framework that is used for building UIs and single-page applications.
The learning curve of Node.js is High [71500 stars on GitHub (as of July 2020)].	The learning curve of Vue.js is comparatively Low.
Support Model–view–controller (MVC) framework.	Support Model-View-ViewModel(MVVM) pattern.
Written in C/C++.	Written in Javascript and Typescript..
It allows you to run JavaScript code on the server-side and Handles requests from the browser.	It is used to build single-page, client-side applications.
Real-time data streaming is handled easily.	Real-time data streaming is not handled by VueJS.
It is fast and lightweight which makes it usable for writing micro-services.	It is faster than any other UI framework and setting-up to an existing project is easy.
It runs on chromes v8 engine and uses an event-driven, non-blocking I/O model.	It uses JavaScript run-time 'Node.js' to compile and run.
No DOM (Document Object Model) is Used.	Virtual DOM (Document Object Model) is Used.
Being single-threaded handles requests easy and fast.	Axios library is used to handle AJAX requests.
Apps using Node.js: LinkedIn, Uber, Netflix, PayPal, Trello, Capital One, Yahoo, Mozilla, etc	Apps using Vue.js: Google, Apple, Nintendo, Behance, Oval Money, Trivago, Font Awesome, Gitlab, etc.
