fanout-graphql-tools-example-micro

Example of how to use fanout-graphql-tools with apollo-server-micro and micro. This also serves as an example of how to use fanout-graphql-tools with any web framework that returns an http.Server.

fanout-graphql-tools exports a GraphqlWsOverWebSocketOverHttpSubscriptionHandlerInstaller constructor that can mutate any http.Server to add support for handling WebSocket-Over-HTTP requests.

Testing locally

1. Install pushpin using these instructions

2. Configure your /etc/pushpin/routes file to contain:

   *,debug localhost:57410,over_http
   

3. In this directory,

   npm install
   npm start
   

   This will run the example GraphQL Server, listening on port 57410

4. Access the example in your web browser through pushpin using http://localhost:7999/graphql

5. Using the GraphiQL Playground UI that should render here, create the following subscription:

   subscription {
     postAdded {
       author,
       comment,
     }
   }

6. Open another tab in the GraphiQL Playground, and send the following mutation:

   mutation {
     addPost(comment:"hi", author:"you") {
       author,
       comment,
     }
   }

7. Switch back to the GraphiQL Playground tab for the subscription, and on the right side you should see the result of your mutation.
