The plan proceeds in three ordered steps: (1) decompose the flat auth.py into clean internal modules, (2) stand up the FastAPI service with its own entry-point and Dockerfile, and (3) replace the monolith's direct auth imports with a thin HTTP client that calls the new service. +> This migration plan decomposes the monolithic Express application into three independent Node.js/Express microservices: Orders, Products, and Frontend. Each service will be self-contained with its own server logic, data, package.json, Dockerfile, and Kubernetes deployment configurations. The Orders and Products services will serve their respective data from local JSON files, while the Frontend service will serve static React files and proxy API requests to the backend Orders and Products services. The original monolith files will remain untouched throughout this process. ## Summary | Metric | Value | |---|---| -| Total steps | 3 | -| Passed | 1 | -| Failed | 1 | -| Skipped | 1 | +| Total steps | 6 | +| Passed | 0 | +| Failed | 0 | +| Skipped | 6 | | Not run | 0 | -| **Overall success rate** | **33%** | -| Planned file changes | 15 | -| Applied file changes | 2 | +| **Overall success rate** | **0%** | +| Planned file changes | 31 | +| Applied file changes | 0 | ## Risk Assessment -High risk: (1) src/auth.py is imported by src/main.py and both router modules — any rename or removal before step-003 completes will cause an ImportError cascade at startup. Run the full test suite between each step. (2) JWT secret_key must be identical in the monolith config and the services/auth/.env during the transition period; a mismatch will silently invalidate all active sessions. (3) Database ownership transfer — after step-002 the auth microservice owns the 'users' table; the monolith must not write to it directly after step-003. Enforce with a revoked DB role. Medium risk: (4) The oauth2_scheme tokenUrl path changes from '/auth/login' (local) to the microservice URL — update any auto-generated OpenAPI docs and client SDKs. Low risk: (5) passlib bcrypt parameters are identical in both environments so no password re-hashing is required. +The primary risks involve ensuring correct configuration of the proxying in the `microservices/src/frontend/server.js` to correctly route requests to the Orders and Products services, especially when deployed in Kubernetes with internal service names. Additionally, verifying that the static file serving in the frontend works as expected for client-side routing. Incorrect `package.json` dependencies or Dockerfile paths could lead to build failures. The original monolith files are not modified, mitigating risks to the existing application. ## Steps Overview | Step ID | Title | Status | Changes | Depends On | Notes | |---|---|---|---|---|---| -| `step-001` | Decompose legacy auth.py into internal service modules | ✅ passed | 5 | — | — | -| `step-002` | Stand up the standalone FastAPI auth microservice | ❌ failed | 6 | `step-001` | Dockerfile build failed | -| `step-003` | Replace monolith direct auth imports with HTTP client calls | ⏭ skipped | 4 | `step-002` | step-002 failed | +| `step-001` | Create base directory structure for microservices | ⏭ skipped | 9 | — | generated from plan only | +| `step-002` | Copy data and static assets to microservices | ⏭ skipped | 7 | `step-001` | generated from plan only | +| `step-003` | Create package.json files for all microservices | ⏭ skipped | 3 | `step-001` | generated from plan only | +| `step-004` | Implement Orders Service server logic and infrastructure | ⏭ skipped | 4 | `step-001`, `step-002`, `step-003` | generated from plan only | +| `step-005` | Implement Products Service server logic and infrastructure | ⏭ skipped | 4 | `step-001`, `step-002`, `step-003` | generated from plan only | +| `step-006` | Implement Frontend Service server logic and infrastructure | ⏭ skipped | 4 | `step-001`, `step-002`, `step-003`, `step-004`, `step-005` | generated from plan only | ## Step Details -### `step-001` — Decompose legacy auth.py into internal service modules ✅ passed +### `step-001` — Create base directory structure for microservices ⏭ skipped -The existing src/auth.py is a 200-line god-module that mixes password hashing, JWT creation/validation, and the User SQLAlchemy model all in one file.
