How eldarnr/rick-and-morty works
Purpose and runtime entry points
Rick and Morty Explorer is a two-tier application for searching, filtering, and viewing character profiles, with AI-generated character commentary. The React/Vite browser client starts at frontend/src/main.tsx and is composed from frontend/src/App.tsx. The Python FastAPI service is exposed through backend/app/main.py, typically run as uvicorn app.main:app.
Frontend application shell and navigation
The client uses React 18, TypeScript, and React Router to present list and detail views. Route definition is centralized in frontend/src/router.tsx; shared navigation/page framing is in frontend/src/layout/Layout.tsx and frontend/src/layout/Navbar.tsx. This boundary keeps route-level data/UI behavior separate from persistent layout.
Character discovery flow
The character browser is implemented by frontend/src/pages/CharacterList.tsx, with reusable result rendering and pagination in frontend/src/components/CharacterCard.tsx and frontend/src/components/Pagination.tsx. User name/status filters and page changes drive requests through the frontend API layer, then render cards or skeleton states while data is pending.
Character detail and AI insight flow
Selecting a card navigates to the profile view in frontend/src/pages/CharacterDetail.tsx. It displays richer character attributes—such as origin, location, and episode data—and requests the backend’s AI-backed description capability. frontend/src/components/CharacterDetailSkeleton.tsx represents the detail loading boundary.
Frontend-to-backend API boundary
frontend/src/api/client.ts is the client-side integration boundary for backend HTTP calls. Domain response shapes are represented in frontend/src/types/index.ts, allowing pages/components to consume typed character data rather than embed transport details. The frontend should not directly depend on the official Rick and Morty API; the FastAPI service is the proxy/facade.
Backend API and service stages
FastAPI initialization/configuration occurs in backend/app/main.py and backend/app/config.py; HTTP endpoints are defined in backend/app/routers.py. Route handlers delegate external API retrieval and Gemini generation to backend/app/services.py. This separates request/response concerns from asynchronous outbound HTTP and AI business logic.
External services and deployment
The backend asynchronously wraps the official Rick and Morty API via HTTPX and calls Google Gemini Pro using a GEMINI_API_KEY environment value. Expected local endpoints are frontend Vite on port 5173 and FastAPI on port 8000. Deployment intent is a static/frontend deployment such as Vercel (frontend/vercel.json) paired with a separately hosted Python backend, e.g. Render.
