Angular Elements
Angular Elements is a feature of the Angular framework that allows developers to package Angular components as custom elements (Web Components), enabling them to be used in any web application regardless of the underlying framework. It leverages the browser's native Web Components APIs to create reusable, framework-agnostic UI elements that can be embedded in non-Angular environments like React, Vue, or plain HTML/JavaScript. This bridges the gap between Angular's component-based architecture and the broader web ecosystem.
Developers should learn Angular Elements when they need to create reusable UI components that must work across different frameworks or in legacy applications, such as when migrating a large codebase incrementally or building a design system for a multi-framework organization. It is particularly useful for embedding Angular components in CMS platforms, micro-frontend architectures, or third-party integrations where framework lock-in is a concern. By using Angular Elements, teams can leverage Angular's powerful features like dependency injection and change detection while maintaining interoperability.
