Development

Prerequisites (Windows)

This repo uses git symlinks. On Windows, enable symlink support so they are checked out correctly:

# Enable symlinks globally (requires Developer Mode or elevated shell)
git config --global core.symlinks true

Backend

uv sync                        # install Python dependencies
uv run -m flow_sdk.server.run  # start backend server on port 9007

The backend serves the API at http://localhost:9007. Bootstrap endpoint: http://localhost:9007/api/v1/graph/bootstrap

Frontend

cd ui
npm install                    # install Node dependencies
npm run dev                    # start Vite dev server on port 4097

The frontend runs at http://localhost:4097 and proxies API calls to the backend.

Running Tests

# All backend tests (from repo root)
python -m pytest tests/ -v

# Unit tests only
python -m pytest tests/unit/ -v

# API tests only
python -m pytest tests/api/ -v

# Frontend tests (requires running backend for api/react tests)
cd ui && npx vitest run

# Frontend build + lint
cd ui && npm run build && npm run lint

Building for pip install

# Build UI assets into server/static/ (required before packaging)
python build_ui.py

# Build the wheel
uv build

build_ui.py must run before uv build — it compiles the frontend into server/static/assets/ which gets included in the wheel. Without this step, the pip-installed server will serve the HTML shell but 404 on JS/CSS assets.

Deployment

Use the deploy script to bump version, tag, push, and publish:

./scripts/deploy_to_github.sh              # runs tests first
./scripts/deploy_to_github.sh --skip-tests # skip tests
./scripts/deploy_to_github.sh --no-pypi    # skip PyPI upload

This will:

1. Increment the patch version in sdk/python/flow_sdk/_version.py
2. Run tests (unless --skip-tests)
3. Commit and tag the release
4. Push to GitHub
5. Build UI assets and wheel
6. Publish to PyPI (unless --no-pypi)
7. Validate the installed package
