Frontend - Kirana AI (React + Vite)
React 19 + Vite + Tailwind CSS v4 single-page app for browsing the catalog,
running semantic search, chatting with the RAG assistant, and (on
/admin) triggering ingestion of new brands.
Full setup steps are in the project documentation (../docs/). This file
is a fast local reference.
Quick start
One command (from the project root)
python run_project.py
Starts the FastAPI backend, waits until /api/health answers, then starts
this Vite dev server - so the API is always up before the UI first calls it.
Use --frontend-only to start just Vite against a backend you're already
running yourself.
Manual
cd frontend
npm install
npm run dev
Open http://localhost:5173 - the Vite dev server proxies /api/* to
http://localhost:8000 automatically (see vite.config.js), so make
sure the backend is running there first (see ../backend/README.md).
Note that Vite binds localhost as IPv6 ([::1]), which browsers handle
fine. Only relevant if you probe it with a tool pinned to IPv4 - use
http://[::1]:5173 there, or pass --host 127.0.0.1.
If your backend runs somewhere else, set VITE_API_BASE_URL in a local
.env file (copy .env.example) instead of relying on the proxy.
Production build
npm run build # outputs to dist/
npm run preview # serve the production build locally to sanity-check it
Pages
/- Browse & Search (sidebar brand/category filters, product grid, semantic search bar) with a toggle to Ask AI, a conversational RAG chat panel that cites which catalog products it used for each answer./admin- Trigger ingestion of a new brand and watch job status.
