IDEA: GraphQL Subscription on Server-sent events

[AlexKenbo]

Are there any plans to add SSE?

I second this request.

I need to support subscriptions for clients that do not allow websockets, usually because a corporate firewall drops them. I currently have code that works around this by repeatedly performing query over http but it is less reliable that I would like. It would be great if Hasura could offer a solution for subscriptions over regular HTTP.

Same here. SSE as alternative would be great

Hello, I would love / need to have sse support for subscription in hasura too, I am ready to try and implement it myself, could some dev from the project give me some pointers on how to approach that challenge ?
I'm not very familliar with haskell nor the projet, I tried to look for the implementation of websockets as reference but had trouble finding it...

This would be great!

Can anyone from Hasura comment as to whether this is under consideration?

[cbarlow1993]

I'd also like to hear whether this is on the roadmap anytime soon.

There is a pretty good spec now at graql-sse. It is a simpler transport and several of the newer GQL providers are including support. However, this has not been noisy enough to attract attention.

@enisdenjo started the campaign in ticket #6264 about a year before this ticket so maybe there is hope for eventual support of SSE. Would certainly make writing clients easier. However, as far as I know Hasura does everything with HTTP/1.1 so it would actually be a pretty big upgrade to HTTP/2.

SSE Support:

• gqlgen
• graphql-mesh
• wundergraph

but Hasura still "under construction" :(
