Mock Directive

In an effort to consolidate GraphQL mocks so that all clients (web, mobile, services) can benefit from schema first development, we are introducing a mock directive.

To take advantage of this directive on your GraphQL type include:

Before

type User {
  _id: ID
  firstName: String
  lastName: String
}

After

type User {
  _id: ID @mock(type: ID)
  firstName: String @mock(type: firstName)
  lastName: String @mock(type: lastName)
}

With these in place, if we make a request to a Roxy server with the header gql-mock, the server will respond with mock data for any fields that have this directive.

How it works

We define our mock directive types [here] We define a MockDirective [here]

Under the hood faker.js is substituting the value in its library based on the type argument provided to the mock directive.

Adding new mocks

1. Define your enum in mockTypes via mockDefinition.graphql
2. Implement your type via mockRegistry.js
3. Decorate your GraphQL type with the directive.
