What's CSS-in-JS Libraries?

CSS-in-JS libraries allow developers to write CSS directly within JavaScript files, enabling dynamic styling based on component state and props. This approach enhances the modularity and reusability of styles, making it easier to manage styles in large applications. These libraries often support features like theming, scoped styles, and automatic vendor prefixing, which streamline the styling process and improve maintainability. By leveraging JavaScript's capabilities, CSS-in-JS libraries can create highly dynamic and responsive designs that adapt to application state, enhancing user experience.

Feature Comparison: styled-components vs jss vs emotion

Syntax and Usability

  • styled-components:

    Styled-components utilize template literals to create styled components, making it intuitive for developers familiar with CSS. This approach allows for easy nesting and theming, enhancing readability and maintainability.

  • jss:

    JSS uses a JavaScript object syntax for defining styles, which can be more familiar to developers who are comfortable with JavaScript. It allows for dynamic styles based on props and state, but may require a bit more boilerplate compared to other libraries.

  • jss:

    Select JSS if you prefer a more traditional approach to styling with a focus on JavaScript object notation. It is ideal for projects that need a robust theming system and dynamic styles, especially when working with React and other component-based libraries.

  • emotion:

    Choose Emotion if you need a highly performant library that offers both styled components and CSS prop syntax, allowing for flexibility in how you write styles. It is particularly useful for projects that require advanced theming capabilities and a strong focus on performance.

Similar Npm Packages to styled-components

styled-components is a popular library for styling React applications using tagged template literals. It allows developers to write CSS directly within their JavaScript files, creating styled components that encapsulate styles and logic. This approach promotes modularity and reusability, making it easier to maintain styles across large applications. Styled-components also support theming, dynamic styling, and server-side rendering, making it a versatile choice for modern web development.

However, there are several alternatives to styled-components that also provide unique features and benefits:

  • emotion is a highly performant and flexible CSS-in-JS library that offers similar capabilities to styled-components. It provides a powerful styling solution with a focus on performance and developer experience. Emotion allows for both styled components and traditional CSS styles, giving developers the flexibility to choose their preferred method of styling. With features like theming, dynamic styles, and a small bundle size, Emotion is an excellent choice for those looking for a robust CSS-in-JS solution that can easily integrate with existing projects.

  • styled-jsx is a library developed by Vercel that provides scoped CSS for React components. It allows developers to write CSS directly within their components while ensuring that styles are scoped to the component, preventing style leakage. Styled-jsx is particularly useful for projects using Next.js, as it integrates seamlessly with its server-side rendering capabilities. If you are looking for a solution that offers scoped styles with minimal configuration and works well with Next.js, styled-jsx is a great option.

Similar Npm Packages to jss

jss is a popular library for CSS-in-JS styling in JavaScript applications. It allows developers to write CSS styles using JavaScript objects, providing a dynamic and modular approach to styling components. JSS is particularly useful for applications that require a high level of customization and theming, as it enables styles to be generated at runtime based on props or application state. Its flexibility and integration with various frameworks make it a solid choice for modern web development.

However, there are several alternatives to JSS that also provide CSS-in-JS solutions. Here are a couple of notable options:

  • emotion is a highly performant and flexible CSS-in-JS library that allows developers to style applications using template literals or object notation. It offers powerful features like theming, automatic vendor prefixing, and server-side rendering support. Emotion is designed to work seamlessly with React and can be easily integrated into existing projects. Its focus on performance and developer experience makes it a popular choice for styling React applications, especially when you need both flexibility and speed.

  • styled-components is another widely-used CSS-in-JS library that enables developers to write actual CSS code within JavaScript files. It utilizes tagged template literals to create styled components, allowing for a clean and intuitive syntax. Styled-components automatically handle vendor prefixes and support theming, making it easy to create reusable and maintainable styles. Its popularity stems from its simplicity and the ability to scope styles to components, preventing style conflicts in larger applications.

Similar Npm Packages to emotion

emotion is a popular CSS-in-JS library designed for styling React applications. It allows developers to write CSS styles with JavaScript, enabling dynamic styling based on component props and state. Emotion provides a powerful and flexible API, allowing for both styled components and traditional CSS styles, making it a versatile choice for modern web development. While Emotion is a robust solution for styling, there are several alternatives worth considering:

  • sass is a preprocessor scripting language that is interpreted or compiled into Cascading Style Sheets (CSS). It extends CSS with features like variables, nested rules, mixins, and functions, making it easier to write and maintain complex stylesheets. If you prefer a more traditional approach to styling and want to leverage the power of variables and nesting without the overhead of JavaScript, Sass is an excellent choice.
  • styled-components is another popular CSS-in-JS library that allows developers to write actual CSS code to style their components. It utilizes tagged template literals to style components, enabling a seamless integration of styles with JavaScript logic. Styled-components also support theming and dynamic styling, making it a great option for applications that require a consistent design system. If you appreciate the CSS-in-JS paradigm but want a slightly different API and feature set, styled-components is a strong alternative.
  • styled-jsx is a CSS-in-JS library specifically designed for Next.js applications. It allows developers to write scoped CSS directly within their components, ensuring that styles are applied only to the respective components. This approach helps prevent style conflicts and promotes better maintainability. If you are working within the Next.js framework and want a simple way to manage styles, styled-jsx is a suitable choice.

README for styled-components

Visual primitives for the component age. Use the best bits of ES6 and CSS to style your apps without stress 💅

downloads: 600k/month Discord gzip size module formats: umd, cjs, esm Code Coverage

Upgrading from v5? See the migration guide.

Utilizing tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allow you to write actual CSS code to style your components. It also removes the mapping between components and styles – using components as a low-level styling construct could not be easier!

const Button = styled.button`
  color: grey;
`;

Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries.

const Button = styled.button({
  color: 'grey',
});

Equivalent to:

const Button = styled.button`
  color: grey;
`;

styled-components is compatible with both React (for web) and React Native – meaning it's the perfect choice even for truly universal apps! See the documentation about React Native for more information.

Supported by Front End Center. Thank you for making this possible!

const Title = styled.h1`
  font-size: 1.5em;
  text-align: center;
  color: palevioletred;
`;

// Create a <Wrapper> react component that renders a <section> with
// some padding and a papayawhip background
const Wrapper = styled.section`
  padding: 4em;
  background: papayawhip;
`;

function MyUI() {
  return (
    // Use them like any other React component – except they're styled!
    <Wrapper>
      <Title>Hello World, this is my first styled component!</Title>
    </Wrapper>
  );
