react-style-singleton

What is react-style-singleton?

The react-style-singleton package is designed for React applications to manage and reuse style tags efficiently. It helps in reducing the overhead of repeatedly rendering identical style tags by creating a singleton pattern for styles. This is particularly useful for components that are instantiated multiple times but use the same underlying styles.

What are react-style-singleton's main functionalities?

Singleton Style Tag

This feature allows you to create a singleton style tag that can be reused across multiple components. The `styleSingleton` function is used to define a style that only gets injected once, even if multiple components use it. This is useful for maintaining consistency and performance in large applications.

import { styleSingleton } from 'react-style-singleton';

const useStyle = styleSingleton();

function App() {
  useStyle(`<style>.myClass { color: red; }</style>`);

  return <div className='myClass'>Hello World</div>;
}

Other packages similar to react-style-singleton

styled-components

Styled-components is a library for React and React Native that allows you to use component-level styles in your application. It uses tagged template literals to style your components. Unlike react-style-singleton, styled-components focuses on scoped CSS for each component rather than singleton patterns, providing more flexibility but potentially more overhead if not managed properly.

emotion

Emotion is a performant and flexible CSS-in-JS library designed for React. It supports both string and object styles and works similarly to styled-components but with optimizations for performance. Emotion does not specifically focus on singleton style tags but offers a wide range of styling capabilities, including dynamic styling which react-style-singleton does not focus on.
