GraphQL
The GraphQL Transform provides a simple to use abstraction that helps you quickly create backends for your web and mobile applications on AWS. With the GraphQL Transform, you define your application’s data model using the GraphQL Schema Definition Language (SDL) and the library handles converting your SDL definition into a set of fully descriptive AWS CloudFormation templates that implement your data model.
The GraphQL Transform simplifies the process of developing, deploying, and maintaining GraphQL APIs. With it, you define your API using the GraphQL Schema Definition Language (SDL) and can then use automation to transform it into a fully descriptive cloudformation template that implements the spec. The transform also provides a framework through which you can define your own transformers as @directives for custom workflows.
@Connection in GraphQL
The _@connection_ directive enables you to specify relationships between @model types. Currently, this supports one-to-one, one-to-many, and many-to-one relationships.
many-to-many relationships can be implemented using two one-to-many connections and a joining @model type.
- Has one
- Has Many
- Belongs To
- Many To Many
Limit
The default number of nested objects is 100. You can override this behavior by setting the limit argument.
Generates
In order to keep connection queries fast and efficient, the GraphQL transform manages global secondary indexes (GSIs) on the generated tables on your behalf when using @connection
