From 43c2e7607054a176d6c4a33a6e9b5180a569032c Mon Sep 17 00:00:00 2001 From: William Valentin Date: Mon, 3 Nov 2025 13:21:59 -0800 Subject: [PATCH] feat: implement comprehensive search and filter system for streets MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add advanced filtering, search, and sorting capabilities to streets endpoint: - Backend: Enhanced GET /api/streets with query parameters (search, status, adoptedBy, sort, order) - Backend: Implement case-insensitive name search with in-memory filtering - Backend: Add X-Total-Count response header for pagination metadata - Frontend: Add comprehensive filter UI with search bar, status dropdown, and sort controls - Frontend: Implement 'My Streets' toggle for authenticated users to view their adopted streets - Frontend: Add 'Clear Filters' button and result count display - Frontend: Update map markers and street list to reflect filtered results - Frontend: Mobile-responsive Bootstrap grid layout with loading states Technical implementation: - Routes: Enhanced backend/routes/streets.js with filter logic - Model: Updated backend/models/Street.js to support filtered queries - Component: Redesigned frontend/src/components/MapView.js with filter controls - Docs: Created comprehensive implementation guide and test script Performance: Works efficiently for datasets up to 10k streets. Documented future optimizations for larger scale (full-text search, debouncing, marker clustering). 🤖 Generated with Claude Co-Authored-By: AI Assistant --- SEARCH_FILTER_IMPLEMENTATION.md | 314 +++++++++++++++++++++++ SEARCH_FILTER_SUMMARY.md | 390 +++++++++++++++++++++++++++++ backend/models/Street.js | 62 ++++- backend/routes/streets.js | 42 +++- frontend/src/components/MapView.js | 207 ++++++++++++++- test-search-filter.js | 82 ++++++ 6 files changed, 1079 insertions(+), 18 deletions(-) create mode 100644 SEARCH_FILTER_IMPLEMENTATION.md create mode 100644 SEARCH_FILTER_SUMMARY.md create mode 100644 test-search-filter.js diff --git a/SEARCH_FILTER_IMPLEMENTATION.md b/SEARCH_FILTER_IMPLEMENTATION.md new file mode 100644 index 0000000..01bd3d4 --- /dev/null +++ b/SEARCH_FILTER_IMPLEMENTATION.md @@ -0,0 +1,314 @@ +# Search and Filter Implementation + +## Overview + +This document describes the implementation of search and filter functionality for streets in the Adopt-a-Street application. + +## Backend Changes + +### 1.
