api-compatibility-check

To detect breaking changes in a GraphQL schema, compare PR diffs or specific schema files to surface backward-incompatible edits like field removals, enum removals, and non-null to nullable changes. This identifies potential issues affecting clients and downstream services.

Breaking changes in GraphQL API evolution include field removals, type changes, required argument additions, enum removals, and non-null to nullable modifications. These backward-incompatible edits can disrupt clients and consumers across domains.

You check GraphQL PR diffs for backward-incompatible edits across domains by comparing schema files against the main branch. This surfaces breaking changes and provides mitigation recommendations to ensure end-to-end compatibility for iOS, Android, and Web clients.

Yes, you can get migration guidance for required argument additions in GraphQL. The compatibility check provides recommended mitigations like deprecation, new fields, or versioning, and outlines a phased rollout plan for safe transitions.

This GraphQL compatibility check works with both specific schema files and PR diffs. You can run a CLI command to diff your target GraphQL schema against the main branch or a PR to surface breaking changes and suggested mitigations.

Automated GraphQL schema diffing identifies structural breaking changes like field removals and required argument additions, but safe API evolution still requires human oversight to apply mitigation recommendations and manage phased rollout plans across clients.
