Right. In my implementation, all GraphQL queries are a POST to my backend at /graphql with a “application/graphql” Content-Type header.

I wrote the network logic into an ember service called “backend” so that it can also add authorization headers etc.. Usage is simple:

this.get('backend').runQuery(
  `
    {
      me {
        id 
        email
      }
    }
  `
).then(data => { 
  dispatch({ type: 'SET_CURRENT_USER', data });
});
