RadCrew Unveiled

Monorepo: Vite React site (frontend) and FAQ chatbot API (backend, FastAPI + Uvicorn).

Prerequisites

• Node.js — see frontend/README.md
• Python 3.11+ — see backend/README.md

Install

From the repository root:

yarn install

(If you use npm instead: npm install.)

• Frontend (Vite, env vars, build, tests, lint): frontend/README.md
• Backend (Python venv, pip install, API env): backend/README.md

Dev (frontend + API)

From the repo root, one command starts both the Vite app and the chat API:

yarn dev

• Frontend only: yarn dev:frontend
• API only: yarn dev:backend (runs Uvicorn with reload on backend)

Environment files live in frontend/.env and backend/.env (copy from each package’s .env.example). Details: frontend/README.md, backend/README.md.

Chatbot flow

• Browser calls POST /chat on the backend URL (VITE_CHATBOT_API_BASE_URL, default http://localhost:8787)
• The API retrieves snippets from static site copy and optional GitHub Markdown
• Hugging Face chat completion (with text-generation fallback) produces grounded answers
• Weak retrieval (with no prior conversation history) returns a safe fallback with contact guidance

Tests

yarn test
yarn test:backend

• Frontend (Vitest): frontend/README.md
• Backend (pytest): backend/README.md

Lint

yarn lint

See frontend/README.md.

Production

• Frontend build / preview: frontend/README.md
• API (Uvicorn): backend/README.md

yarn build:backend runs compileall on backend/app as a quick syntax check only.
