In the monolith at /Users/USER/workspace/doctolib/doctolib, find how module federation consumers are configured - specifically how the monolith knows where to load tpf-national-health-records-ui from (what URL/port). Look in: 1. Any file referencing "module-federation" or "loadModule" or "5180" 2. The vite.plugins.mts file - read its full content 3. Any rspack config files 4. The .__mf__temp directory 5. Any .env files mentioning "tpf" or "federation" 6. The packages/@doctolib/upfront-core/ directory if it exists

Report the exact file and config that tells the monolith which URL to use for tpf-national-health-records-ui module federation.

I'll help you find how module federation consumers are configured in the monolith. Let me start by exploring the structure and searching for relevant configuration files.

Tools used:

Perfect! Now I have the complete picture. Let me create a comprehensive summary of my findings.

Summary

I've found exactly how the monolith configures module federation consumers and specifically where it knows to load tpf-national-health-records-ui from port 5180.

Key Configuration Files:

1. Doctor Entrypoint (Main Consumer): - File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/monolith-mfr-tools/src/doctor/mfr-dev-overrides.json - Contains: Development-time module federation URLs, including: ```json "tpf-national-health-records-ui": "http://localhost:5180/mf-manifest.json"

`` - **Line 9**: Specifies thattpf-national-health-records-ui` loads from port 5180

2. Doctor Dependencies (Version Constraints): - File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/monolith-mfr-tools/src/doctor/mfr-dependencies.json - Line 11: Specifies version requirement: "tpf-national-health-records-ui": "^12.1.0"

3. Initialization: - File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/monolith-mfr-tools/src/doctor/init-doctor-module-federation.ts - Function: initDoctorModuleFederation() imports both mfr-dependencies.json and mfr-dev-overrides.json and calls initFederation()

4. Runtime Configuration: - File: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/monolith-mfr-tools/src/shared/init-federation.ts - Key Logic: Lines 48-55 show that devRemotesJSON (which includes the localhost:5180 URL) is: - Loaded from mfr-dev-overrides.json only when NODE_ENV !== 'production' - Passed to configureRuntime() via the dev.remoteEntries property - Used by @doctolib/upfront-core/module-federation to resolve module URLs at runtime

5. Consumer Usage: - Files: Entrypoints like /Users/USER/workspace/doctolib/doctolib/app/assets/javascripts/entrypoints-content/components/AppConfiguration.tsx call initDoctorModuleFederation() to initialize module federation with the port 5180 configuration.

The Answer:

The exact config that tells the monolith to load tpf-national-health-records-ui from port 5180 is in: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/monolith-mfr-tools/src/doctor/mfr-dev-overrides.json (line 9)

This file is imported by the initialization function and used by @doctolib/upfront-core/module-federation's configureRuntime() to dynamically resolve the module's manifest location during development.
