This will start the server on http://localhost:8080/ws:

• --cors: allow CORS for all origins and routes. Required when making PV 'put' requests from a web application.

Test client

There are two web interfaces that can be used to query the server:

• GraphiQL: http://localhost:8080/ws
  This uses the old websocket protocol 'graphql-ws' (from the subscription-transport-ws) library.

• Altair: https://altair-gql.sirmuel.design/ or can be installed as a web addon from https://altair.sirmuel.design/#download. Both the new websocket protocol 'graphql-transport-ws' (from graphql-ws library) and the old protocol can be specified in the subscription

  Configuration:

  • GET: http://localhost:8080/ws
  • Subscription URL: ws://localhost:8080/ws
  • Subscription type: Websocket or Websocket (graphql-ws) for the new protocol
  • Connection parameters: {}

Example query:

query {
  getChannel(id: "ssim://sine") {
    value {
      float
    }
  }
}

Example subscription:

subscription {
  subscribeChannel(id: "ssim://sine") {
    value {
      float
    }
  }
}
