React Vs Node Js

Posted on  by admin

React and Node.js are the two popular JavaScript tech stacks used to build fast, dynamic, and data-intensive web applications. But we can’t say that both work in the same way. Yes, you heard it right. They are not competing but complementary to each other. Node.js is a platform, while React is a JavaScript library. It means that if you are building an application with Node.js, then there are chances of using React too in the application and vice versa.

So, how to compare them? This article will help you learn the basic information of these (React and Node.js) technologies. We will also compare React vs. Node.js with criteria like popularity, learning curve, community support, and more.

When & Who Created React?

Plus, we will also have a look at the comparison table. Let’s get started.

Most prominent features of Node.js:

React is a JavaScript library built by Facebook to create UIs using components. Components are reusable and help organize code effectively. React uses Virtual DOM to keep track of the changes made to components. It only updates the virtual DOM, which reduces expensive re-rendering on some data changes. React came into existence when the Facebook newsfeed team faced problems maintaining and managing DOM updates.

2. Popularity: Which technologies are most frequently used?

The DOM is slow, making the user interface difficult to work with. To solve the problem, Facebook developed its library, React. It is fast, provides flexibility in building user interfaces, and overcomes the difficulties faced by DOM updates. React was first launched on May 29, 2013. The project was created by Jordan Walke, who works at Facebook.

Wrap Up!

  • He came up with the idea and found a way to overcome DOM updates performance issues.
  • After solving this problem, Facebook decided to open source React and turn it into a community project.
  • Its core features are:. Virtual DOM — React is built on top of the virtual DOM, which reduces expensive re-rendering by using a lightweight representation of the real DOM.
  • When any data changes occur in components, React updates only the necessary fields in the real DOM.
  • This way, it saves time and reuses existing HTML elements as much as possible.

How Did React Come Into Existence?

Components -Components are reusable and modular pieces of code, making it easy to write and maintain large applications. These components can be further divided into smaller components, called child components. JSX -It is a JavaScript syntax extension that looks similar to HTML. It allows you to write your markup in JS rather than templates or web views.

Thus, it makes it easier to keep track of the content on the page, as it’s all in one place. One-way data binding -Data flows in one direction. The UI updates automatically with changes to the state.

Using simple functions, you can trigger UI updates when the application state changes. React can be used in various web applications, including new projects, existing projects, and mobile apps. It’s a perfect fit for any UI that requires dynamic updates. Some companies currently using React are Yahoo, Instagram, Netflix, Airbnb, Imgur, Dropbox, & Sony.

Node.js usage statistics and popularity:

  • Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code outside browsers.
  • It is lightweight, efficient, and perfect for data-intensive real-time applications across distributed devices.
  • Node.js came into existence when the team at Joyent faced problems with using JavaScript on the server-side.
  • They found it challenging to integrate JavaScript with C++ and use it across distributed devices. Then Ryan Dahl, a developer working on one of their products, created Node.js and used Google’s V8 JavaScript engine(the same JavaScript engine that powers the Chrome browser) to build it.
  • He made use of non-blocking I/O to handle concurrent connections efficiently. Then Joyent open-sourced it in 2009; many companies use Node.js to build their web services.

4. Community Support: How easy is finding developers who know the technology?

TypeAn open-source, client-side library for delivering high-performance dynamic apps.An open-source framework for generating dynamic web page content.
Ideal Use CasesDynamic apps, complex architecture.Data streaming, API services, microservices.
  • Some of the core features are:.
  • Events -Node.js runs on an event-driven architecture based on the “process” module, making it lightweight and efficient.
  • This event-driven architecture helps Node.js to create fast web servers.
  • Single-Threaded -Node.js is single-threaded, meaning Node.js can handle only one process.
  • If there are multiple concurrent requests, they will queue up for processing(unless numerous CPU cores).
  • Asynchronous -It follows non-blocking asynchronous input/output to handle concurrent connections efficiently and effectively.
  • As an example, consider an online shopping portal.
  • Requests for adding products would be blocked if Node.js did not support asynchronous calls until the product was added to the cart and the user checked out.
  • Non-blocking I/O -While non-blocking input/output is one of the reasons for Node.js’s efficiency, it also has another advantage.
  • It allows developers to handle concurrent requests more easily by delegating them to a JavaScript function.
  • Thus, it results in cleaner code. You can hire Node.js developersto build web servers, real-time websites such as chat and collaboration tools, and APIs(application programming interfaces) that power mobile apps.
  • Some companies currently using Node.js are PayPal, Uber, Walmart, and more.
  • Now, let’s break down how two of these are different and how they can be used together:.
  • React and Node.js are two different technologies with different features.

Why use NodeJs for Web Application Development?

React is a JavaScript library used to build user interfaces of applications. It uses JSX, which looks similar to HTML but is still valid JavaScript code. Thus, it makes it easier & smoother for developers to write large applications with many UI components. React can be used with other frameworks but has gained immense popularity on its own. On the other hand, Node.js is a JavaScript run-time environment that can be run on various devices. It allows developers to write high-performance applications where they don’t have to deal with I/O operations directly.
