Lucia

3kb library for tiny web apps

Declarative

Declarative

Lucia provides a declarative API similar to Vue to create views, making development predictable and intuitive through markup-centric code.

Reactive

Reactive

When the view is changed and trapped by the observer, the internal AST will automatically react and will update and render the new view in realtime.

Lightweight

Lightweight

Lucia is extremely light and performant as it renders directives only if necessary by skipping static nodes through element references.
