sse-starlette provides server sent events for startlette and FastApi. I'm evaluating for use with htmx.
## Installation:
``` bash
pip install sse-starlette
```
## Usage:
``` python
import asyncio
import uvicorn
from starlette.applications import Starlette
from starlette.routing import Route
from sse_starlette.sse import EventSourceResponse
async def numbers(minimum, maximum):
for i in range(minimum, maximum + 1):
await asyncio.sleep(0.9)
yield dict(data=i)
async def sse(request):
generator = numbers(1, 5)
return EventSourceResponse(generator)
routes = [
Route("/", endpoint=sse)
]
app = Starlette(debug=True, routes=routes)
if __name__ == "__main__":
uvicorn.run(app, host="0.0.0.0", port=8000, log_level='info')
```
