minattest-app-host (BFF)

Overview

• .NET 9 minimal app acting as a reverse proxy for both the React frontend and the API during development.
• Uses YARP to forward:
  • /api/* to the API (API_URL, default https://localhost:7172).
  • everything else to the frontend dev server (FRONTEND_URL, default http://localhost:5173).

Configure

• Env vars:
  • FRONTEND_URL (default: http://localhost:5173)
  • API_URL (default: https://localhost:7172)
• launchSettings.json sets both for dev profiles.

Run

• Start your API (e.g., at https://localhost:7172).
• Start your React dev server (e.g., npm run dev on port 5173).
• From repo root: dotnet run --project frontend/minattest-app-host
• Open the BFF URL shown in the console (e.g., https://localhost:10001).
  • Requests to /api/... go to your API.
  • All other paths (including /) go to the React dev server.

Notes

• WebSockets are enabled to support HMR from Vite/CRA dev servers.
• If your API uses the ASP.NET Core dev certificate, ensure it's trusted: dotnet dev-certs https --trust.
• Later, add auth and API composition here while keeping the frontend origin hidden from browsers.
