FastAPI's redirect_slashes=True causes GET /api/v1/canvas to 307 redirect
to /api/v1/canvas/ — axios follows the redirect but drops the Authorization
header, resulting in 403. Fixed by declaring routes as empty string instead
of '/' so no redirect is issued. Same fix applied to nodes and edges routes.
Updated all tests to use paths without trailing slashes.
Frontend:
- Split nodeTypes/edgeTypes into separate .ts files (react-refresh)
- Remove setState-in-effect in NodeModal (key prop reset)
- Fix handleSave accessed before declaration (useRef pattern)
- Exclude src/components/ui/** from eslint (shadcn generated)
- Use defineConfig from vitest/config for test type support
Backend:
- ruff --fix: sort imports, datetime.UTC alias
- Raise line-length to 120, ignore E501 in tests
- Break long update_node/update_edge signatures
- pyproject.toml: per-file-ignores for tests
