GraphQL Subscriptions with Server Sent Events

[@brightworld7550]

A very good video Jamie. It was very informative and straight to the point. A video with Subscriptions usig MQTT or REDIS would be much appreciated too, because it is the closest to production (which is what really matters). Also if possible can you make a video about actually deploying a server that implements subscriptions and the best possible options. (Not sure if it can be deployed on the edge, eg; Cloudflare Workers). Thank you and best regards.

hi on that main.ts you created a resolver variable and you write all your resolvers there, what if i already created an app that all the resolvers already separated, so like i have master modules, like master book, it has its own service module and resolver, master car, it has its own service module and resolver, in many explanation of graphql-ws i need to make that typedefs and resolvers, the typedefs is totally fine can read from the schema, but how about the resolvers if in my case i already separated them all?

why does couldnot connect to endpoint comes when trying to run subscription in graphql playground from backend?

[@notrab]

Do you have a reproducer repo?

[@RedCloudServices]

Does Apollo Studio or Sandbox allow us to integrate tools from The Guild like Yoga?

[@notrab]

You should be able to point it to any GraphQL api but some things might not work (SSE live queries etc)

How can we pass headers like authorization with SSE from client side

[@theratcode3424]

I am using set context from apollo client to pass the authorization with headers but during subscriptions it's not working

Hi Jamie, does this still have a maximum connections limit?

[@nemes1x]

Is this limit issue solved using http2?

[@notrab]

With http/2 the limit is higher but most likely suitable for most use cases.

please send code link for this video . Also please tell us how can we contact you if we have any doubts :)

[@notrab]

Hey, the code can be found at graphql.wtf/episodes/52-graphql-subscriptions-with-server-sent-events

[@nemes1x]

Great Video again! Do you recommend SSE for production? I am looking forward to the next videos about subscriptions topic

[@notrab]

Thanks ❤ SSE works fine in production but does have some limitations you want to be aware of (max open connections). I guess it also depends on what you want from your GraphQL subscriptions. www.graphql-yoga.com/docs/features/subscriptions#sse-vs-websocket
