About

Lit is an open-source JavaScript library for building fast and lightweight web components, developed as the successor to Google's Polymer project.

The library uses native Web Components APIs with reactive properties and HTML template literals, reduces boilerplate compared to Polymer, updates only changed parts of the DOM for faster rendering, and supports server-side rendering, TypeScript, and integration with frameworks such as React, Vue, and Angular.

Polymer is a legacy open-source JavaScript library created by Google for building components based on Web Components standards.

The library introduced declarative custom elements, data binding, shadow DOM helpers, and reusable component packaging, and later evolved into the Lit project focused on lightweight and faster component development.
