What is a "blazor circuit"?

Question

There are plenty of mentions to "Blazor circuit" term on the documentation, however I cannot find a definition of the term. I guess it is something like some kind of state associated to the user session.

Please, could you provide a more precise definition of what a Blazor circuit really is?

Answer 1

From MS docs :

Blazor Server is a stateful framework. While users interact with an app, they maintain a connection to the server known as a circuit. The circuit holds active component instances, plus many other aspects of state, such as:

• The most recent rendered output of components.
• The current set of event-handling delegates that could be triggered by client-side events.

It's simply a fancy name for a web socket. Ofcourse the data sent is specialized to Blazor apps, but at the end of the day it's just a web socket connection.
