What's Lightweight React Alternatives?

Inferno, Preact, and React-DOM are libraries designed to facilitate the creation of user interfaces in web applications, each with its unique focus and performance characteristics. Inferno is known for its high performance and is optimized for speed, making it suitable for applications where rendering speed is critical. Preact is a lightweight alternative to React, providing a similar API but with a smaller footprint, making it ideal for projects where size is a concern. React-DOM is a part of the React ecosystem that specifically handles rendering React components to the DOM, ensuring efficient updates and rendering. These libraries cater to different needs in the web development landscape, allowing developers to choose based on performance, size, and compatibility with existing React code.

Feature Comparison: react-dom vs preact vs inferno

Performance

  • react-dom:

    React-DOM focuses on efficiently rendering React components to the DOM. It employs a reconciliation algorithm that optimizes updates and minimizes re-renders, ensuring that only the necessary parts of the UI are updated when the state changes.

  • preact:

    Preact is significantly smaller than React, which translates to faster load times and improved performance in smaller applications. It achieves this by providing a similar API to React but with a more lightweight implementation, making it suitable for projects where performance and size are critical.

  • inferno:

    Inferno is designed for maximum performance, boasting a virtual DOM that is optimized for speed. It uses a highly efficient diffing algorithm that minimizes the number of updates to the actual DOM, resulting in faster rendering times, especially in applications with frequent updates.

API Compatibility

  • react-dom:

    React-DOM is an integral part of the React ecosystem, providing a consistent API for rendering React components. It is tightly coupled with React and is essential for any React application that needs to interact with the DOM.

  • preact:

    Preact is designed to be compatible with React, allowing developers to use most React libraries and tools with minimal changes. This compatibility makes it an attractive option for those looking to reduce bundle size without sacrificing functionality.

  • inferno:

    Inferno offers a React-like API, making it easier for developers familiar with React to transition to or integrate Inferno into their projects. However, it also introduces some unique features that may require learning new patterns.

Bundle Size

  • react-dom:

    React-DOM is not a standalone library and is part of the larger React ecosystem. While it is optimized for performance, it does contribute to the overall bundle size of a React application, which can be a consideration for developers looking to optimize their applications.

  • preact:

    Preact is one of the smallest libraries available for building user interfaces, making it an excellent choice for projects where every kilobyte counts. Its minimal size allows for faster downloads and improved performance on low-bandwidth connections.

  • inferno:

    Inferno is lightweight, but it is still larger than Preact. Its focus on performance comes with some additional features that can increase the bundle size slightly compared to Preact, making it a good choice for performance-focused applications that can afford a slightly larger footprint.

Community and Ecosystem

  • react-dom:

    React-DOM benefits from the extensive React ecosystem, which includes a vast array of libraries, tools, and community support. This makes it a safe choice for developers looking for robust solutions and resources.

  • preact:

    Preact has a growing community and ecosystem, with many developers contributing to its development and creating plugins and tools. Its compatibility with React further enhances its ecosystem, allowing developers to leverage existing React resources.

  • inferno:

    Inferno has a smaller community compared to React, which can lead to fewer resources and third-party libraries. However, its focus on performance has garnered a dedicated following among developers looking for speed.

Learning Curve

  • react-dom:

    React-DOM is straightforward for those already familiar with React. Its integration into the React ecosystem means that learning it is often part of the broader learning process of React itself.

  • preact:

    Preact's API is nearly identical to React's, making it easy for React developers to pick up. The learning curve is minimal, allowing for quick adoption in existing projects.

  • inferno:

    Inferno's API is similar to React, which can ease the learning curve for developers familiar with React. However, some unique features may require additional learning for optimal usage.

How to Choose: react-dom vs preact vs inferno
  • inferno:

    Choose Inferno if you need a highly performant library that can handle complex UIs with minimal overhead, especially for applications requiring rapid rendering and updates.

README for react-dom

react-dom

This package serves as the entry point to the DOM and server renderers for React. It is intended to be paired with the generic React package, which is shipped as react to npm.

Installation

npm install react react-dom

Usage

In the browser

import { createRoot } from 'react-dom/client';

function App() {
  return <div>Hello World</div>;
}

const root = createRoot(document.getElementById('root'));
root.render(<App />);

On the server

import { renderToPipeableStream } from 'react-dom/server';

function App() {
  return <div>Hello World</div>;
}

function handleRequest(res) {
  // ... in your server handler ...
  const stream = renderToPipeableStream(<App />, {
    onShellReady() {
      res.statusCode = 200;
      res.setHeader('Content-type', 'text/html');
      stream.pipe(res);
    },
    // ...
  });
}
