Graphql-playground: playground subscription doesn't listen with graphcool@next

[miyi]

I started a graphcool@next project with the initial User and Post model. I want to listen to subscriptions in the playground for the creation of posts and users, but i get blanks. The same thing happens with all graphcool subscription tutorials as well (freedom, worldchat, instagram).

I hard coded subscription endpoint shows "subscribe is undefined". The above picture happens when I change the subscription endpoint to the real one as shown in the CLI. Is subscription in the playground broken at the moment?

allposts show multiple posts created, but subscription listener is empty

I can confirm it's also not working for me...

Thanks for reporting! When clicking on the cog symbol, what does the
subscription endpoint say?

@timsuchanek I got the same problem. Subscription endpoint was empty and I cannot typed anything on the input box. Well, I saw an improper web-socket was called on the network tab(inspect element).

v1.0.2,v1.1.1 on mac

Came to see if someone else had this bug. I am on v1.0.2 on a mac, running a local deployment, and cannot change the subscription endpoint.

Have this issue too.

It seems it's a critical issue. /cc @timsuchanek

The subscriptions endpoint now is being configured with graphql config. You can read more about that here: https://github.com/graphcool/graphql-config#specifying-endpoint-info

The workflow looks like this:
Have a folder with .graphqlconfig file.
Execute graphql playground, gc playground or prisma playground, all work the same.
The according endpoint will be opened with subscriptions enabled.

If you have a prisma or graphcool project, you don't need to provide the endpoints by hand - they're deducted from the prisma.yml or graphcool.yml.
You just need to provide an "extension" in the graphql config:

projects:
  my-db:
    extensions:
      prisma: prisma.yml
      graphcool: graphcool.yml

Let me know if you have any issues with this workflow.
Reopen if this is not solving your issue.
Thanks!

@timsuchanek I'm having the same issue trying to test subscriptions through the prisma/examples/subscriptions example (https://github.com/graphcool/prisma/issues/1671)

.graphqlconfig.yml

projects:
  app:
    schemaPath: "src/schema.graphql"
    extensions:
      endpoints:
        default: "http://localhost:4000"
  database:
    schemaPath: "src/generated/prisma.graphql"
    extensions:
      prisma: database/prisma.yml

On the other hand, the graphql-yoga/subscriptions example works. It's implementation is slightly different, using Pubsub: https://github.com/graphcool/graphql-yoga/tree/master/examples/subscriptions

Thanks for reporting @hoodsy ! Did you already try what @nilan suggested here? https://github.com/graphcool/prisma/issues/1671#issuecomment-358896690
