⚠️ Warning: No servers are used, or harmed, in the resolving of these GraphQL queries

To quickly show a few of the features in action here we have:

• Setting up a GraphQL query handler and making a query
• Using graphql-paper package, an in-memory graphql store, which allows stateful queries (try a mutation and see the change persist in subsequent queries)
• An embedded logWrapper highlighted on all root-level Query resolvers for logging. Check the developer console for helpful logging after each query run.

Go ahead and do a few queries and mutations (see changes persist)

The Code

// 1. Setup your handler

const handler = new GraphQLHandler({
  // optionally, provide a base resolver map
  resolverMap,

  // use middlewares from packages, make your own,
  // and embed resolver wrappers
  middlewares: [
    embed({
      // Highlight makes it easy to declaratively select
      // what resolvers should be wrapped with the `logWrapper`
      highlight: (h) => h.include(field(['Query', '*']))
      wrappers: [logWrapper],
    }),
  ]

  // add dependencies needed by middlewares or resolvers
  dependencies: {
    graphqlSchema,
    paper: new Paper(graphqlSchema)
  },
});


// 2. Run queries (or mutations)!

handler.query(`
  query {
    ...
  }
`);
