Implementing GraphQL Servers

Take-away:

  1. design, code, schema first approaches
  2. SDL generation audits
  3. secretField: SecretType @featureFlagged(name: "secret")
  4. mutating the context object
  5. how to audit the query root
  6. metadata on types
  7. security and calculate complexity with dry run
  8. REDACTED tooling

  • [ ] Modular Schemas
  • [ ] Testing

Servers are created given a type definition and a runtime.

Resolvers:

  function resolveName(parent, arguments, context) {
      return parent.name;
  }

  resolveName({name: 'Jason'});
  query {
    user(id: "1234") {
      name
    }
  }

Resolvers cascade from the root.

  digraph G {
          resolver -> {
                  root
                  gco
          }
  }

Schema-first approaches allow for the definition of types but without any business logic.

This requires creating a root with a resolver as well as the schema with the root resolver (as compared with a secondary resolver?).

  const root = {
      hello: () => {
          return 'Hello'
      }
  }

  graphql(schema, '{ hello }', root). then((resp) => {
      console.log(resp);
  });

Resolvers

  • Keep business logic out of resolvers
  • Immmutable context
  • No field ordering dependency
