Fight!

Popularity

Both @emotion/css and JSS are popular CSS-in-JS libraries in the JavaScript community. However, @emotion/css is often considered more popular and widely adopted due to its simplicity and modern approach to styling.

Styling Methodology

@emotion/css follows a style composition approach where styles are composed together using JavaScript. It allows for writing CSS-in-JS in a similar syntax to traditional CSS. JSS, on the other hand, follows a style object approach where you define styles as JavaScript objects. The choice between the two depends on personal preference and the requirements of the project.

Developer Experience

@emotion/css provides a better developer experience with an intuitive API and great tooling support. It offers built-in support for theming, keyframe animations, and media queries. JSS also has a good developer experience but might have a steeper learning curve for beginners due to its more flexible and customizable nature.

Performance

In terms of performance, both libraries are efficient and perform well. However, @emotion/css has an advantage in terms of performance due to its usage of runtime styling extraction which allows for better server-side rendering performance and faster client-side hydration.

Integration

@emotion/css is well-integrated with React and is the official CSS-in-JS library recommended by the React team. It provides hooks and components specifically designed to work seamlessly with React. JSS, on the other hand, is framework-agnostic and can be used with any JavaScript framework or even without a framework.

Community and Ecosystem

Both @emotion/css and JSS have active and supportive communities. However, @emotion/css has a larger and more mature ecosystem with a wide range of companion libraries and tools. It also has good compatibility with CSS frameworks like Tailwind CSS, making it easier to integrate into existing projects.
