Add Tree Hazard Detector and Netlify Deployment Config #137

google-labs-jules · 2026-01-11T09:55:48Z

This change adds a new "Tree Hazard Detector" feature to the application, allowing users to report fallen trees or dangerous vegetation. The feature uses Hugging Face's CLIP model for zero-shot image classification. Additionally, a netlify.toml file is added to configure the frontend for deployment on Netlify, including proxy rules to redirect API requests to the Render backend. Backend unit tests are included to verify the new endpoint.

- Implemented `detect_tree_clip` in `backend/hf_service.py` to identify fallen trees and vegetation hazards. - Added `/api/detect-tree-hazard` endpoint in `backend/main.py`. - Created `frontend/src/TreeDetector.jsx` using `react-webcam` for image capture. - Updated `App.jsx` and `Home.jsx` to include the new detector route and UI button. - Added `netlify.toml` for frontend deployment with API proxy to Render backend. - Included backend unit tests in `tests/test_tree_detection.py`. - Updated `frontend/package.json` to include `react-webcam` dependency.

Inconsistent indentation detected. Line 47 has extra leading spaces (5 spaces) compared to the standard 4-space indentation used in the rest of the function. This should be corrected to maintain consistent code formatting.

The removal of security headers (X-Frame-Options, X-Content-Type-Options, X-XSS-Protection, and Referrer-Policy) reduces the application's security posture. These headers provide important protection against clickjacking, MIME-type sniffing, XSS attacks, and referrer leakage. Consider keeping these security headers to maintain best security practices for the frontend deployment.

The new detect_tree_clip function is missing a docstring, unlike the other detection functions in this file (e.g., detect_vandalism_clip has a docstring). Add a docstring to describe the function's purpose, parameters, and return value for consistency and better maintainability.
