Stencil is a compiler used for authoring web component libraries and developing framework-agnostic user interface elements. It transforms TypeScript and JSX source code into standard custom elements that operate natively in the browser.
The project enables the implementation of design systems and enterprise component systems by sharing a single codebase across different JavaScript frameworks. It generates specific adapter layers that allow these custom elements to be used as native components in React, Angular, and Vue.
The toolset incorporates ahead-of-time compilation to minimize bundle size and utilizes lazy-loading component hydration to defer the initialization of logic until an element is rendered. It also employs virtual DOM diffing and a static type system to manage component properties and events.
