What are some real-world examples of pub/sub in Node.js?
Pub/sub is widely used in Node.js applications. For instance, in chat applications, messages can be published to a channel and all subscribers receive them instantly.
Can you give me another example?
Sure! In a stock market application, updates about stock prices can be published, and all clients subscribed to those stocks will receive real-time updates.
How does this compare to traditional request/response models?
Unlike request/response, where the client waits for a response, pub/sub allows for asynchronous communication, enabling real-time updates without direct requests.
What libraries can I use for implementing pub/sub in Node.js?
You can use libraries like Redis, MQTT, or even built-in Node.js EventEmitter for implementing pub/sub patterns.
