Using WebSockets in Angular enables real-time bidirectional communication between client and server for live updates and messaging. As the creator of CoreUI with over 12 years of Angular experience since 2014, I’ve implemented WebSocket connections in numerous real-time applications. Angular integrates with WebSockets using RxJS observables providing reactive streams for incoming messages and connection management. This approach enables real-time features like chat, notifications, live data feeds, and collaborative editing.

Implementing WebSockets in Vue enables real-time, bidirectional communication for live updates, chat applications, and streaming data. As the creator of CoreUI with over 12 years of Vue.js experience since 2014, I’ve built real-time dashboards with WebSocket connections. Vue’s reactivity system works seamlessly with WebSocket messages, automatically updating the UI when new data arrives. This approach creates responsive applications with live data synchronization without polling.

Emitting events from child to parent components is essential for building interactive Angular applications with proper component communication. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented countless event-driven component interactions over 25 years of development. From my expertise, the most reliable approach is to use the @Output decorator with EventEmitter to create custom events that parent components can listen to. This pattern maintains loose coupling while enabling effective component communication.
