Stencil
Stencil is a compiler-based web component framework that generates standards-compliant custom elements (Web Components) using TypeScript and JSX. It allows developers to build reusable UI components that work across modern frameworks like React, Angular, and Vue, or in any HTML page without a framework. Stencil focuses on performance by generating highly optimized vanilla web components with features like lazy-loading and server-side rendering.
Developers should use Stencil when they need to create a design system or component library that must be framework-agnostic and reusable across multiple projects or teams. It's ideal for enterprise applications where consistency and interoperability between different tech stacks (e.g., React and Angular) are critical. Stencil is also beneficial for performance-sensitive applications due to its small bundle sizes and efficient rendering.
