Whereas the aforementioned principles teach you how to be smart with your code, the following principles will teach you to be wisewith your code. Some of them are strange, and many of them are humorous, but they’re all equally practical and important. Take heed
Sometimes, we want users to log in to our application using their existing credentials from third-party applications, such as Facebook, Twitter, Google, etc. In this article, we are going to look into the authentication of ASP.NET Core app using a Google account.
1. What is OOPS?
OOPS is abbreviated as Object Oriented Programming system in which programs are considered as a collection of objects. Each object is nothing but an instance of a class.
In short, domain events help you to express, explicitly, the domain rules, based in the ubiquitous language provided by the domain experts. Domain events also enable a better separation of concerns among classes within the same domain.
It's important to ensure that, just like a database transaction, either all the operations related to a domain event finish successfully or none of them do.
Domain events are similar to messaging-style events, with one important difference. With real messaging, message queuing, message brokers, or a service bus using AMQP, a message is always sent asynchronously and communicated across processes and machines. This is useful for integrating multiple Bounded Contexts, microservices, or even different applications. However, with domain events, you want to raise an event from the domain operation you are currently running, but you want any side effects to occur within the same domain.
The domain events and their side effects (the actions triggered afterwards that are managed by event handlers) should occur almost immediately, usually in-process, and within the same domain. Thus, domain events could be synchronous or asynchronous. Integration events, however, should always be asynchronous.
