Mador offers an 80-line JavaScript runtime for adding reactive state bindings to existing DOM without a framework

Mador is a tiny native ES module that lets developers bind reactive state to existing DOM elements using a simple read/write tuple. It avoids components, templates, and virtual DOM, while tracking state dependencies so bindings rerun only when relevant values change.

Mador reflects a growing interest in micro-libraries that add targeted reactivity without adopting a full frontend framework. Its appeal is likely strongest for small apps, static sites, and progressive enhancement workflows where developers want modern interactivity with minimal overhead.
