Describe the feature you'd like to request

When I made some fields deprecated by adding @deprecated directive in schema.graphql, these deprecations are ignored in autogenerated src/API.ts file.

For example,

type ToDo @model {
  id: ID!
  name: String!
  due: String! @deprecated(reason: "use dueDate instead")
  dueDate: AWSDateTime!
}

turns into this

export type ToDo = {
  __typeName: "ToDo";
  id: string;
  name: string;
  due: string;
  dueDate: string;
  createdAt: string;
  updatedAt: string;
};

though I hope like this.

export type ToDo = {
  __typeName: "ToDo";
  id: string;
  name: string;
  /** @deprecated use dueDate instead */
  due: string;
  dueDate: string;
  createdAt: string;
  updatedAt: string;
};

In the current situation, we can't notice the use of deprecated fields so that unexpected deletion of field might occur. Are there any alternative solution for this? If not, I strongly hope the implementation of this feature.

Describe the solution you'd like

Explicit marker of deprecated fields.

Describe alternatives you've considered

Nothing especially.

Hi @tsuyuni, we do not support @deprecated directive. Marking this as a feature request.
