Decorators that help creating graphql server easier These decorators don't create types or input. It just help create domain's mutations or queries

@controller

Add prototypes getQueries and getMutations into a class

@query(specs)

• specs: Object
  • name: String. Optional. Default is generate from class name and method name. Ex: User_find, User_findOne
  • description: String. Optional
  • type: GraphqlType. Required
  • args: query arguments. Optional

@mutation(specs)

• specs: Object
  • name: String. Optional. Default is generate from class name and method name. Ex: User_create, User_delete
  • description: String. Optional
  • type: GraphqlType. Required
  • args: mutation arguments. Optional

@controller
class Product {
  @query({
    type: Products
  })
  find(root, args, context) {
    const collection = context.collections.Product;
    return collection.find();
  }

  @query({
    name: 'getProduct'
    type: Product,
    args: {
      id: {
        type: new GraphQLNonNull(GraphQLString)
      }
    }
  })
  findOne(root, args, context) {
    const collection = context.collections.Product;
    return collection.findOne({id: args.id});
  }
  // mutations
  @mutation({
    type: Product,
    args: CreateProductArgs
  })
  create(root, args, context) {
    const collection = context.collections.Product;
    return collection.save(args.data);
  }
}

// Add to schema
const product = new Product();

let schemaDef = {
  query: new GraphQLObjectType({
    name: 'Query',
    fields: {
      ...product.getQueries()
    }
  }),
  mutation: new GraphQLObjectType({
    name: 'Mutation',
    fields: {
      ...product.getMutations()
    }
  }),
};
const schema =  new GraphQLSchema(schemaDef);
