GraphQL Proxy to REST API Endpoints

Step Group Step Description Location (Old Repo / New Repo) Notes
Repo Setup Freeze GraphQL schema and tag baseline Old Repo Prevents schema drift during migration
Repo Setup Initialize new Flask REST repo New Repo Clean project, no shared code
Repo Setup Add constructor-only Injector subclass New Repo Disallow method/property/service-locator injection
Repo Setup Add folder structure (services, blueprints, tests) New Repo Keeps REST code isolated
Inventory List all GraphQL queries → map to GET Old Repo Drives REST endpoint creation
Inventory List all GraphQL mutations → map to POST/PATCH Old Repo Ensures full coverage
Inventory Identify nested GraphQL fields to flatten Old Repo REST is resource-first
Inventory Identify resolvers with multi-model logic Old Repo These require decomposition
REST Design Define REST resources from scratch New Repo No existing REST resources
REST Design Define GET/POST/PATCH endpoints per resource New Repo Only allowed HTTP verbs
REST Design Define URL structure (/api/v1/) New Repo Stable REST contract
REST Design Define request/response JSON shapes New Repo No error envelopes needed
Service Layer Extract resolver logic into service classes New Repo Shared-nothing architecture
Service Layer Ensure services use constructor injection only New Repo Enforced by custom Injector
Service Layer Remove all GraphQL context usage New Repo Services must be pure
Blueprints Create one blueprint per domain New Repo Constructor-injected services
Blueprints Implement GET/POST/PATCH routes New Repo No auth, no error handling
Blueprints Use request.json for input parsing New Repo Minimalist request handling
Blueprints Return plain JSON responses New Repo No exception handling
Postman Add Postman collection generator New Repo Auto-scans Flask URL map
Postman Expose /postman.json or generate in CI New Repo Supports client migration
Proxy Layer Implement REST proxy class (GET/POST/PATCH) Old Repo Forwards GraphQL ops to REST
Proxy Layer Add feature flags per operation Old Repo Enables reversible migration
Proxy Layer Wrap resolvers with toggle logic Old Repo Switch old/new behavior safely
Proxy Layer Forward GraphQL queries to REST GET Old Repo Reversible cutover
Proxy Layer Forward GraphQL mutations to REST POST/PATCH Old Repo Reversible cutover
Staged Migration Implement REST endpoint for one operation New Repo Incremental rollout
Staged Migration Add pytest tests for the new endpoint New Repo DI override for test doubles
Staged Migration Add endpoint to Postman collection New Repo Keeps documentation aligned
Staged Migration Flip feature flag for that operation Old Repo GraphQL now proxies to REST
Staged Migration Monitor behavior and roll back if needed Old Repo Reversible at any time
Staged Migration Remove old resolver logic after stability Old Repo Only when safe
Final Removal Remove all GraphQL resolvers Old Repo After all ops migrated
Final Removal Remove GraphQL schema and middleware Old Repo GraphQL fully retired
Final Removal Remove GraphiQL/Playground Old Repo No longer needed
Final Removal Remove GraphQL libraries Old Repo Clean dependency tree
Final Removal Freeze or archive old repo Old Repo REST becomes canonical API
Final Cleanup Remove proxy layer and feature flags Old Repo No more dual operation
Final Cleanup Regenerate final Postman collection New Repo REST-only documentation
Final Cleanup Tag final migration release in both repos Both Marks completion
