GraphiQL setup to support websockets

[jamesmmchugh]

GraphiQL has utilities for creating fetchers for both HTTP and WS, currently the spring-graphql setup of GraphiQL only supports a HTTP meaning subscriptions over websocket cannot be tested via the UI:

For example, see: https://github.com/graphql/graphiql/blob/main/packages/graphiql-toolkit/docs/create-fetcher.md

Interesting!
How does that materialize in the GraphiQL interface? Is there a live sample demonstrating this feature?

[jamesmmchugh]

I'm not aware of any live samples. It's quite easy to test by overriding the index.html that this boot project serves for GraphiQL. I can provide a copy of what I used if desired.

When using, GraphiQL displays the lastest message in the the query output section. Any further analysis of the websocket connection can be done in the browers debugger.

GraphiQL lets you run a single subscription at a time, and terminates the websocket connection at when the subscription completes. It also turns the run button into a stop button so you can terminate the subscription early if desired.
