Designing a GraphQL API

Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.

ActiveRecord embedding

	module ActiveRecord
	# Allows embedding of ActiveRecord models.
	#
	# Embedding other ActiveRecord models is a composition of the two
	# and leads to the following behaviour:
	#
	# - Nested attributes are accepted on the parent without the _attributes suffix
	# - Mass assignment security allows the embedded attributes
	# - Embedded models are destroyed with the parent when not appearing in an update again
	# - Embedded documents appears in the JSON output
