Deprecated Metadata Upgrades

Codemods can upgrade your metadata to the latest version so you can take advantage of the latest engine features.

Codemods below are listed with the CLI version they were added in.

upgrade-object-boolean-expression-types (v2.4.0)

Upgrades the deprecated ObjectBooleanExpressionType to the new BooleanExpressionType.

This enables filtering Models on nested objects and arrays, and based on relationships.

ddn codemod upgrade-object-boolean-expression-types

By default the codemod will run against the supergraph.yaml from the context. Provide --supergraph or --subgraph to run the codemod against a different supergraph or subgraph.

upgrade-graphqlconfig-aggregate (v2.4.0)

Add aggregates support to metadata through AggregateExpression. Use aggregates (like sum, min, count, etc) in your GraphQL API.

ddn codemod upgrade-graphqlconfig-aggregate

By default the codemod will run against the supergraph.yaml from the context.

The GraphqlConfig metadata object is required to be upgraded to enable aggregates for all subgraphs.

Run against a specific supergraph.yaml or subgraph.yaml file

ddn codemod upgrade-graphqlconfig-aggregate --supergraph ./supergraph.cloud.yaml
ddn codemod upgrade-graphqlconfig-aggregate --subgraph ./app/subgraph.yaml

upgrade-graphqlconfig-subscriptions (v2.14.0)
