# stenciljs/core

A toolchain for building scalable, enterprise-ready component systems on top of TypeScript and Web Component standards. Stencil components can be distributed natively to React, Angular, Vue, (+ more) and traditional web applications from a single, framework-agnostic codebase.

## What it is
Stencil is a TypeScript-based compiler and toolchain for building standards-compliant Web Components (Custom Elements) using JSX, decorators, and an async rendering pipeline. It generates framework-agnostic components that can be distributed natively or via generated wrappers to React, Angular, Vue, and plain web applications from a single codebase.

## Use cases
- build a design system as reusable web components
- create a component library that works with React, Angular, and Vue
- compile TypeScript and JSX into standards-compliant custom elements
- generate framework wrapper packages from one codebase
- build a fast, framework-agnostic PWA or website
- share UI components across multiple frontend teams and frameworks

## When to choose
- you need one component codebase consumed by multiple frameworks
- you are building an enterprise design system or component library
- you want to avoid framework churn by targeting web standards
- you need prerendering/SSG and a built-in dev server for component development

## When to avoid
- you are building a single-framework app and prefer that framework's native tooling
- you need a large ecosystem of third-party components and plugins
- your team has no TypeScript experience
- you need fine-grained control over raw Custom Elements APIs
