nanocomponent is a tiny library for building native‑DOM UI components that work efficiently with DOM‑diffing tools (e.g., nanomorph, morphdom) or frameworks like Choo. It provides a class‑based API with `createElement`, `update`, and lifecycle hooks so components render only when needed, making UI updates fast and lightweight. It’s aimed at JavaScript developers who want low‑overhead, framework‑agnostic components for single‑page apps or any project that manipulates the DOM directly.
