Hello, folks! In this repository, we'll dive into the concept of Notification Chains—an architectural idea pertinent to multiple subscribers interested in particular events. 🎉
Notification Chains serve as a design pattern to facilitate the communication between a publisher and multiple subscribers. They are commonly used to notify subscribers about specific events.
Note: This is a programming language-agnostic concept. 🌐
- Publisher: The entity generating the events. 📡
- Subscribers: Parties interested in the events generated by the publisher. 📬
- Events: Occurrences generated or produced by the publisher. 🎟️
Notification Chains are a prevalent communication pattern in the software industry. You'll undoubtedly come across this architecture in various scenarios—making it an essential topic for both budding and seasoned developers. 👩💻👨💻
- Event Generation: The publisher generates an event. 🎉
- Registration: Subscribers can register (and unregister) for these events at their discretion. ✅❎
- Event Distribution: Once an event occurs, it's pushed to the interested subscribers. 📭
Who Can Be Publishers or Subscribers?
- Threads of the same process 🧵
- Multiple processes on the same/different systems 🖥️🌐
- Different components of a large software system ⚙️🔩
Understanding Notification Chains will significantly benefit you when working on complex projects that involve multiple entities needing to communicate about events. 🏆
Good luck with your coding journey! 🍀👨💻👩💻
