Emotion
Emotion is a performant, flexible CSS-in-JS library designed for writing CSS styles using JavaScript, supporting both string-based and object-based styles while delivering a strong developer experience, complete with source maps, labels, and testing utilities. It offers two powerful usage patterns; a framework-agnostic approach which requires no special configuration yet supports vendor-prefixing, nested selectors, media queries, and class composition through the CSS and CX functions; and a React-optimized variant providing advanced features like the CSS prop for direct styling (similar to the style prop but with support for nested selectors, media queries, and theming capabilities), zero-configuration server-side rendering, native theming, and compatibility with ESLint tooling. Emotion also supports styled-component-like APIs, enabling tag-based or component-based styled elements with dynamic prop-driven styling.

Qodana
Static code analysis by Qodana helps development teams follow agreed quality standards, and deliver readable, maintainable, and secure code. Powered by JetBrains. We’ve been perfecting the code analysis in our IDEs for 20+ years based on feedback from millions of community members. Qodana relies on the lines of JetBrains IDEs and brings their intelligence to the CI side. Just like in our IDEs, Qodana’s analysis is accurate but not overbearing and understands the nuances of your code. Integration with tools developers use daily, including JetBrains IDEs, makes it easy to work with Qodana’s results in whichever tool you're most comfortable with. Qodana doesn’t only report problems; it also suggests automatic fixes. Qodana calculates licenses per active contributor, so it won’t cause unexpected expenses or charge you for growing your project (as we don’t calculate LOCs). It’s also free for open-source projects.
