What is Web Components?
Turkish: Web Components
Web Components use Custom Elements, Shadow DOM, and templates to create framework-independent custom HTML elements.
What are Web Components?
Web Components are a standards-based way to build reusable custom HTML elements in the browser. A component can be added to a page with its own tag, such as <price-card> or <date-picker>, without being tied to one framework.
Core Parts
Custom Elements define the element name and behavior. Shadow DOM isolates the component’s internal DOM and CSS from the surrounding page. HTML templates and slots provide reusable markup and controlled content placement.
This model runs on the real DOM; React, Vue, or Angular are not required. It can still be used alongside those frameworks. Libraries such as Lit make Web Components easier to author and maintain.
Business Use
Web Components are useful when teams using different stacks need to share a common design system. In banks, telecom companies, and large enterprises, the same component library may need to work in a React app, a CMS page, and a legacy application.
The tradeoffs include SSR support, form integration, accessibility, testing setup, and legacy browser requirements. Web Components are not automatically better than framework components; their strongest value appears when technology-independent distribution matters.
