Popularity
@primer/css is the official CSS utility library from GitHub's Primer design system, and it has gained popularity within the GitHub community. On the other hand, jss is a popular JavaScript CSS-in-JS library widely used in the React ecosystem.
Use Case
@primer/css is primarily focused on providing ready-to-use utility classes and CSS styles to quickly style web applications. It is more suitable for projects that want to leverage a pre-defined design system and maintain consistent styles. jss, on the other hand, is a JavaScript CSS-in-JS library that allows you to create and manage styles programmatically. It is better suited for projects that require dynamic styling or custom theming.
Integration
@primer/css is designed to be used with any CSS-in-JS library or traditional CSS workflow. It provides a set of pre-built CSS classes and utility functions that can be easily integrated into your project. jss, on the other hand, is a standalone JavaScript library that works well with React and other frameworks. It provides an API to define and manage styles directly in your JavaScript code.
Performance
@primer/css is optimized for performance and has a small footprint. It leverages atomic CSS and functional CSS principles to generate minimal and reusable styles. jss, on the other hand, adds a runtime CSS generation layer which can impact performance compared to static CSS bundling. However, depending on the use case, the performance difference may not be significant.
Developer Experience
@primer/css provides a consistent set of utility classes and styles, making it easy to apply styles without writing custom CSS. It requires minimal configuration and is a good choice for developers who prefer a plug-and-play solution. jss, on the other hand, offers more flexibility but requires writing and managing styles programmatically. It has a bit steeper learning curve but provides greater control and customization options.
Community Support
Both packages have active communities and are well-maintained. However, @primer/css benefits from being part of the GitHub ecosystem and has a larger community support due to its association with the popular Primer design system. jss also has a dedicated community and is widely used in the React community, with many plugins and integrations available.
