Is it possible to use gzip compression? #67

Closed paolodina closed 3 years ago

paolodina commented 3 years ago

Hello, the application where I'm using django-eventstream sends every few seconds a good amount of text data using send_event. I wonder if it'd be possible to send compressed messages to the clients instead of full responses (~100kb).

I need to reduce the outgoing bandwidth, thanks for any advice you could give.

I'd also consider to use something in front of hypercorn if this could help. But have no idea what to do.

Maybe put Nginx in front?

paolodina commented 3 years ago

@jkarneges I thought it could have be managed by django-eventstream, but yes, I'll try to put caddy as a reverse proxy enabling gzip server side, good idea.

jkarneges commented 3 years ago

Yeah for now a proxy may be easiest.

For gzip to be done in the actual Django app, I think it would be best done as middleware. This should be possible by writing ASGI middleware code. The Starlette framework appears to have a gzip middleware, although I don't know how portable it is.

Long term I hope all normal Django middlware will work with ASGI, but that could be awhile.
