FAQ Frequently Asked Questions

What is a web component and why use them?

Web components are reusable, encapsulated HTML elements that work across different frameworks and vanilla JavaScript. They provide component-based development without framework lock-in, ensuring long-term compatibility.

Can I configure properties and events for my components?

Yes, the generator typically allows defining custom properties, attributes, events, and methods. This creates fully functional components that can communicate with parent applications and other components.

What output formats are available?

Most generators support ES6 modules, ES5 for legacy browsers, TypeScript definitions, and sometimes framework-specific wrappers for React, Vue, or Angular integration.

Does the generator include Shadow DOM support?

Yes, Shadow DOM encapsulation is usually included, providing style isolation and preventing CSS conflicts. This ensures your components work reliably regardless of the host page's styling.

Can I use these components across different projects?

Absolutely! Web components are framework-agnostic and work in vanilla JavaScript, React, Vue, Angular, or any web application. This makes them perfect for design systems and cross-project reusability.
