# CADDesigner React UI
This directory contains the standalone TypeScript + React frontend for the CADDesigner project.
## What It Includes
- A collapsible session sidebar with conversation stats and history
- A left-side chat timeline that interleaves assistant text and tool calls in event order
- A right-side workbench with a resizable 3D preview pane and code viewer
- Native streaming from the backend `POST /v1/chat/events` SSE endpoint
- A Vite dev proxy for `/health` and `/v1/*`
## Run It
For the standard local workflow from the repo root, use the startup scripts:
```bash
uv run python start_caddesigner_full.py
```
If you are working on the frontend itself, start the FastAPI backend first on
`http://127.0.0.1:8000`, then run:
```bash
pnpm install
pnpm dev
```
The direct Vite dev server runs on `http://127.0.0.1:4173` by default.
The wrapper script `start_caddesigner_ui.py` starts the same frontend on
`http://127.0.0.1:7860` and auto-installs dependencies when `node_modules/`
is missing.
## Build It
```bash
pnpm build
```
## Notes
- `frontend/.gitignore` ignores local frontend build artifacts like `node_modules/` and `dist/`.
- The startup scripts prefer `pnpm`; they fall back to `npm` only if `pnpm` is unavailable.
- The current 3D viewport focuses on STL previews, which matches the agent's main output flow.
- Model preview assets are loaded through the backend artifact endpoints added under `/v1/conversations/{conversation_id}/artifacts/*`.
