Migrating from 'express-graphql' (a non-default WS Subscriptions URL)

[lisberPontes]

Hi there,

I'm currently moving from 'express-graphql' into 'graphql-yoga'

In the former code we use a custom URL for the subscriptions, something like:
'/api/bridge/subscriptions'

And we could pass this info to graphiql when calling the method:
graphqlHTTP

graphiqlConfig = {
subscriptionEndpoint: 'FULL WS URL (ws://localhost/api/bridge/subscriptions',
}

However, I'm struggling to 'inject' the subscription endpoint when calling the method:
createYoga

Hence, my question is:

Can I change/override the default subscription endpoint when configuring Yoga? if so, how?

Thanks in advance!

Hey hey, sorry for the delayed answer. If you're following the graphql-ws example , you can just change the graphqlEndpoint option in createYoga because the WS route is the same as regular HTTP.

Hey,

Thanks for coming back @enisdenjo!

Hence, just to be sure.

The path we se on 'graphqlEndpoint', for example 'api/graphiql'

It will always be the same for both: http and ws, right ?

My main question is:
Can we have a different path for each of them (ws (subscriptions) and http(queries))

For example:

• queries => http://localhost/api/graphiql/
• ws => http://localhost/api/subscriptions/

??

Thanks in advance!

Yep.

Yes, just use a different path when instantiating the WebSocketServer:

const wsServer = new WebSocketServer({
  server: httpServer,
-  path: yogaApp.graphqlEndpoint
+  path: '/my-sub-path'
})
