matchmediaquery

matchmediaquery is an open-source JavaScript library providing isomorphic media query functionality, allowing developers to check CSS media queries both in browser environments and server-side contexts. Originally forked from the `matchmedia` project due to its maintainer's publishing delays, this library aimed to provide an active alternative. However, its last stable version (0.4.2) was published in late 2015, and the project has seen no significant updates or maintenance since. As a result, it is considered abandoned and may not be suitable for modern web development, lacking support for contemporary JavaScript module systems (ESM), TypeScript definitions, or up-to-date media query specifications. Its primary differentiator was its isomorphic capability, which is now often handled by more modern, actively maintained libraries or frameworks.
