ObjectToGraphQL

GraphQL Query generator from Ruby object structure.

gem 'object_to_graphql'

Usage

object = {
  user: {
    name: "Alice",
    email_address: "alice@example.com",
    accounts: [
      { name: "alice1" },
    ],
  }
}
ObjectToGraphQL.generate(object)
# => {
#      user {
#        name
#        emailAddress
#        accounts {
#          name
#        }
#      }
#    }

It works with arguments

object = {
  user: {
    name: "Alice",
    email_address: "alice@example.com",
    accounts: [
      { name: "alice1" },
    ],
  }
}

arguments = [
  # [[:path, :to, :the_field, :to_be_injected_argument], {name: argument_name, value: argument_value}]
  [[:user], {name: "ID", value: "id-1"}]
  [[:user, :name], {name: "separator", value: ","}],
  [[:user, :accounts], {name: "order", value: "desc"}]
]

ObjectToGraphQL.generate(object, arguments)
# => {
#      user(ID: "id-1") {
#        name(separator: ",")
#        emailAddress
#        accounts(order: "desc") {
#          name
#        }
#      }
#    }

It works with variables

object = {
  user: {
    name: "Alice",
    email_address: "alice@example.com",
    accounts: [
      { name: "alice1" },
    ],
  }
}

arguments = [
  [[:user], {name: "id", value: "$user_id"}],
]
variables = [
  {name: "$user_id", type: "ID!"}
]

ObjectToGraphQL.generate(object, arguments, variables)
# => query($user_id: ID!) {
#      user(id: $user_id) {
#        name
#        emailAddress
#        accounts {
#          name
#        }
#      }
#    }
