2025 Report: Destructive Malware in Open Source Packages
Destructive malware is rising across open source registries, using delays and kill switches to wipe code, break builds, and disrupt CI/CD.
@emotion/core
Advanced tools
Styled-components is a library for React and React Native that allows you to use component-level styles in your application. It uses tagged template literals to style your components. It is similar to @emotion/core in providing a way to write CSS in JS, but styled-components focuses more on component-based styling with a slightly different syntax.
JSS is a CSS-in-JS library that allows you to write CSS in JavaScript. It is framework agnostic and can be used with any JavaScript framework or library. JSS provides a more extensive API for defining styles and supports plugins for extending its capabilities. Compared to @emotion/core, JSS offers more flexibility and control but might have a steeper learning curve.
Linaria is a zero-runtime CSS-in-JS library that extracts CSS to separate files at build time, resulting in smaller JavaScript bundles. Unlike @emotion/core, which injects styles at runtime, Linaria's approach to extracting static CSS files can lead to better performance for static sites or applications where runtime overhead is a concern.
