Applying reactive programming with RxPy
Reactive programming is one of the emerging popular programming paradigms nowadays that focuses on asynchronous data streams and operations that can manage executions, events, repositories, and exception propagations. It utilizes the publisher-subscriber programming approach, which builds asynchronous interactions between software components and transactions.
The library used to apply reactive streams to build services transactions and API functions in this chapter is reactivex, so install the module using the pip command:
pip install reactivex
The reactivex module has an Observable class that generates data sources for the subscribers to consume. Observer is another API class that pertains to the subscriber entities. reactivex will not be a complete reactive programming library without its operators. The following is a vote-counting service implementation that uses the reactivex utilities:
from reactivex import Observable, Observer...
