๐Ÿ…ฐ๏ธ Sharing data between Angular components with observables

February 22, 2025

๐Ÿ‘€See: https://lnkd.in/efKNXAxi

In Angular applications, components need to communicate, and RxJS Observables help facilitate this interaction by allowing data sharing through subscriptions.

๐Ÿ”” Observables โ€“ Work like a newsletter subscription: when new data is emitted, all subscribers receive updates.

๐Ÿ”„ Subjects โ€“ A special type of Observable that allows multiple listeners to receive the same emitted value.

Types of Subjects:
๐ŸŽฏ Subject โ€“ A basic multicast Observable where multiple subscribers get the same emitted value.
๐Ÿ“Œ BehaviorSubject โ€“ Similar to a Subject, it immediately emits the last stored value upon subscription, making it useful for managing state.
๐Ÿš€ Subjectโ€“ Emits events without carrying a value, ideal for notifying actions (e.g., user interactions, process completion).
