Migrate a REST API to GraphQL incrementally by establishing a wrapper gateway to expose REST endpoints as GraphQL, allowing gradual endpoint migration and deprecation without breaking existing clients.

Incremental REST to GraphQL migration uses a wrapper layer and schema stitching to wrap REST endpoints, enabling you to migrate endpoints one by one while gradually deprecating the old REST services.

A GraphQL wrapper uses data transformers and resolvers to map REST responses to GraphQL types, managing RESTDataSource wrappers to fetch data and translate it into the GraphQL schema structure.

Yes, schema stitching combines multiple REST services into a unified GraphQL API, allowing you to wrap various REST endpoints and manage data loading, caching, and error mapping across services.

A phased migration plan is necessary when wrapping REST endpoints with GraphQL to systematically manage the incremental rollout, data loading, caching, and error mapping requirements across large REST backends.

Choosing an incremental GraphQL wrapper over a full rewrite reduces risk by avoiding breaking existing clients, allowing you to migrate large REST backends gradually while maintaining continuous functionality.
