Class Method Details

.use(schema, **kwargs) ⇒ Object

The first argument is the GraphQLSchema class that this plugin is used on. It accepts the following names arguments:

  • ‘callback` (`Method`): If passed, this will be called with a lambda as argument. Calling the passed lambda will sync the schema to Stellate via HTTP. This is useful if you want to move this request into a non- blocking process (e.g. using Sidekiq) rather than the default behavior of performing a blocking HTTP request which can increase overall response times of your API.
