React Js Vs Preact: Application Development Made Easier

React Js Vs Preact: Application Development Made Easier

React Js Vs Preact is the most discussed comparison within the javascript frameworks. React Js unquestionably leads the IT business with its numerous features and functionalities. Moreover, React Js is the most requested framework for building web apps.

But precisely what is Preact? Have you heard of the business Preact? This technology is marketed as a lightweight alternative to React for web application development. In this blog, we will compare and contrast React Js Vs Preact and the advantages and disadvantages of each technology.

What Is Preact?

Preact is a JavaScript library that is considered the lightweight 3kb alternative to React js while maintaining the same current API and ECMA Script compatibility.

Furthermore, it outperforms other JavaScript frameworks in terms of speed and implements the virtual DOM.

Why Choose Preact?

If you are concerned about the app’s performance, speed, and size, Preact is the ideal option. Web apps can be easily created using Preact. While having a comparison of

Aside from that, it’s a small library that doesn’t necessitate extra effort for learning. Furthermore, because of its similarity and compatibility with React, it is a simple library to use with the existing React package, with some aliasing, i.e., using preact/compat.

In React Js Vs Preact it is very important to know why you need each and every framework with its advantages and disadvantages.

Advantages Of Preact

Quick and light
Preact is the finest framework for designing high-performance lightweight apps because it is only 3.5 kb in size and renders swiftly.
It is extremely compatible with the React API and uses the same ECMA Script, making it efficient enough to be integrated with an existing React project for improved performance.
Big Ecosystem
It is well-documented, which simplifies the learning curve. Moreover, it also has a large community with many contributors who are eager to fix bugs and solve problems.
CLI devoted to
Preact provides a strong CLI that allows developers to create PWAs in seconds without having to configure WebPack, babel, Terser, and other tools.
It features a package called preact/compat that provides complete compatibility. It allows developers to leverage React libraries with Preact to build ReactDOM code without changing the workflow or codebase.

Disadvantages Of Preact

Mimics Respond
Preact was created as a lightweight replacement for React js. As a result, most of the programming done with this library mirrors React js rather than pioneering app development.
Additional library use
To connect Preact and React-based npm packages, it is necessary to use extra libraries like as preact/compat, preact/test-utils, and so on. As a result, the project is enormous and slow.
There is no synthetic event handling
Preact is based on browser API and does not support synthetic event handling, which can affect app performance and cause maintenance issues when using both React and Preact for development and production.

What Is React Js?

The most popular JavaScript library for creating interactive user interfaces is React. React js has emerged as the top choice for web app development among developers.

Furthermore, if you want to create an application using react js should definitely hire react js developer as he/she has wide experience and will help your business grow.

Why Choose React Js?

React js is an excellent choice for creating complex and highly scalable applications, particularly single-page apps. It also provides efficient server-side rendering, making it the best JavaScript framework for developing apps that are easy to optimize for search engines.

Furthermore, the strong global community of developers and contributors makes it the most popular framework for building web applications among developers and businesses.

As we saw earlier the advantages and disadvantages of preact let’s get a detailed comparison of React Js Vs Preact with the advantages and disadvantages of react js.

Advantages Of React Js

Data Binding in One Direction
React js provides unidirectional data binding, which reduces the likelihood of errors and simplifies debugging.
This includes extensive documentation, including tutorials and examples, to make learning as simple as possible.
A sizable community
Furthermore, react js has a vast developer and contributor community, making it the finest framework for web app development.
Components that are reusable
Reusable components enable developers to divide the complex user interface into several components that can be reused in other parts of the application, resulting in faster app development.
React js supports JSX for writing HTML in JavaScript, which aids in the creation of UI features by reflecting changes in the app in real time.

Disadvantages Of React Js

Framework with No Opinions
Because React is an agnostic framework, it may be used to define architecture in a variety of ways. However, it can present problems if developers lack architectural understanding.
View-focused Library
As a view-centric library, React necessitates some legwork to figure out several aspects such as state management, routing, and data handling, relying on various third-party modules and libraries such as Redux and NPM.

React Js Vs Preact: What Do You Think?

You can utilize the open-source JavaScript libraries Preact and React. React js is most popular because of its reusable components, although Preact is favored for performance reasons. We recommend that you choose based on your business objectives and development needs.

However, you can use both libraries or alternate between them as needed. Apart from that, developers do not need to learn a completely new technology to use Preact, but they should be familiar with React.

React js leads the market in terms of rich functionality, whereas Preact has an advantage in terms of lightning-fast performance. So, if you want to create little applications like landing pages and PWAs that load quickly, Preact is the way to go. However, you cannot construct a complicated app in Preact on your own. For such complicated projects, you will need to use React.

React Js Vs Preact: The Difference

App Dimensions
Preact is significantly smaller than React.
Loading React apps take a long time, making the rendering process slow and complex. Preact, on the other hand, renders more quickly.
Event Management
React uses its own synthetic event system for event handling, which reduces app performance, whereas Preact does not use synthetic events. Instead, it makes use of the browser’s addEventListener to improve performance and size.
JSX and HTML usage
Preact, unlike React, allows you to use old HTML properties because it does not employ JSX for client-side templating.


In conclusion to this, we can now get to know which one to use for development and which not to. Every javascript framework present has its pros and cons depending on the need you have.

Furthermore, if you want to develop an application or a website we recommend you hire a software development company. These companies are experts and can guide you throughout the process.
