## Overview

This is a task-management web application: users create, view, edit, delete, complete, search, and filter tasks. The React app owns task state and coordinates the UI and API calls; a service module handles most HTTP requests, while status toggling calls the API directly. The Express API queries a local MySQL database. The frontend components and backend routes are shown in the excerpts; no README was provided, so undocumented capabilities and relationships are not inferred.

Main entry points: [`frontend/src/App.jsx`](https://github.com/chrstan23/taskmanagementapp/blob/main/frontend/src/App.jsx) (Task app), [`backend/server.js`](https://github.com/chrstan23/taskmanagementapp/blob/main/backend/server.js) (Task routes), [`frontend/src/services/taskService.jsx`](https://github.com/chrstan23/taskmanagementapp/blob/main/frontend/src/services/taskService.jsx) (Task service), [`backend/db.js`](https://github.com/chrstan23/taskmanagementapp/blob/main/backend/db.js) (MySQL connector)
