Scope
@primer/css is a CSS framework specifically designed and developed by GitHub. It focuses on providing a consistent and reusable CSS foundation for GitHub's web interfaces. Semantic UI, on the other hand, is a more general-purpose UI framework that provides a wide range of pre-built UI components and themes.
Customization
Both packages offer customization options. @primer/css allows you to easily customize the CSS variables and apply your own styles. Semantic UI offers theming capabilities and allows you to customize various aspects of the UI components using CSS and JavaScript.
Developer Experience
@primer/css has a more modern and modular approach to CSS, utilizing CSS-in-JS and CSS variables. It is built with a focus on GitHub's development workflow and aims to enhance developer productivity. Semantic UI follows a traditional CSS approach and provides CSS classes for styling components. The developer experience may vary depending on personal preference and familiarity with the different approaches.
Component Ecosystem
Semantic UI offers a wide range of pre-built UI components with their own unique styles and functionality. It provides a rich and extensive component library that covers various use cases. @primer/css, being more focused on GitHub's specific needs, offers a smaller set of components which are tailored for GitHub's web interfaces. If your project requires a diverse and comprehensive set of UI components, Semantic UI might be a better choice.
Documentation and Support
Semantic UI has extensive documentation, a dedicated website, and an active community. It provides detailed usage guides, examples, and showcases. @primer/css has documentation specifically tailored for GitHub's development workflow and is well-documented within the context of GitHub's projects. However, it may have less comprehensive documentation and community support outside of GitHub's specific use cases.
