Styled JSX is a CSS-in-JS library for styling React components. It allows you to write CSS directly in your JavaScript code using a syntax similar to traditional CSS. Styled JSX provides scoped styles, meaning that the styles you define for a component only apply to that component and its children, avoiding global style conflicts.

Fight!

Popularity

Both JSS and styled-jsx are popular choices for styling in React applications. JSS has been around for longer and has a larger user base, while styled-jsx gained popularity due to its integration with Next.js. Both packages have a significant following in the React community.

Styling Approach

JSS is a CSS-in-JS library that allows you to write styles in JavaScript using a JavaScript API. It provides a powerful and flexible styling solution with support for dynamic styles and theming. styled-jsx, on the other hand, is a CSS-in-JS library specifically designed for Next.js. It allows you to write CSS directly in your JavaScript files using a scoped style tag.

Integration

JSS can be used with any React framework or library, including Next.js. It provides integrations with popular UI libraries like Material-UI and supports server-side rendering. styled-jsx, on the other hand, is tightly integrated with Next.js and provides a seamless styling experience for Next.js applications. It automatically handles server-side rendering and supports CSS encapsulation.

Performance

JSS generates unique class names for each component, which can result in larger CSS files. However, it provides optimizations like dynamic style injection and style caching to improve performance. styled-jsx uses a unique style scoping mechanism that generates unique class names for each component, ensuring that styles are scoped and isolated. This can lead to smaller CSS files and better performance.

Developer Experience

JSS provides a rich and flexible API for defining styles in JavaScript. It supports various styling paradigms like CSS, SASS, and CSS-in-JS. It also has good TypeScript support and comprehensive documentation. styled-jsx provides a simple and intuitive API for writing CSS directly in JavaScript files. It has excellent integration with Next.js and provides a smooth development experience for Next.js projects.

Community and Maintenance

Both JSS and styled-jsx have active communities and are well-maintained. JSS is maintained by the team behind Material-UI and has a strong ecosystem of plugins and extensions. styled-jsx is maintained by the Next.js team and benefits from the popularity and support of the Next.js community.
