Server-Sent events example

This example illustrates how to use built-in features for Server-sent events (SSE).

Note that, even though BlackSheep supports built-in features for SSE only since version 2.0.6, previous versions of the web framework also could support SSE, as they support response streaming.

Running the example:

1. create a Python virtual environment
2. install dependencies
3. run with uvicorn server:app to test with uvicorn, or hypercorn server:app to test with hypercorn
4. open the page in a web browser, you should see the message on the page updated every second, using information from the server

This example also shows how the is_stopping function can be used to detect when the application server is shutting down.

from blacksheep.server.application import is_stopping
