Lume.js is a reactive state library that connects ordinary JavaScript objects to HTML through data attributes. Its examples bind text and input fields to a shared state object, with changes reflected in the corresponding elements. The project avoids a separate component syntax, a compiler and a virtual DOM, aiming to keep the interface close to standard browser HTML and JavaScript.
Developers can load it through a module script or install the npm package. The documentation describes an extensible handler system, optional addons and TypeScript declarations. Handlers let a project add behavior for additional attributes, while imports can be limited to the pieces being used. The site publishes versioned examples and migration material, so teams can distinguish the currently documented release from older implementations before adopting it.
