## Overview

GitHub Profile Explorer is a React application for finding developers, viewing profiles and repository insights, revisiting recent searches, and saving favorite profiles. The main journey is navigation or username search to a profile, where the frontend requests live GitHub data through the Express API; repository browsing has its own route. The backend proxies GitHub and optionally caches user and repository responses in MongoDB. Profile history and favorites use browser local storage. Repository-page internals were not sampled, so its specific data wiring is not asserted.

Main entry points: [`src/App.jsx`](https://github.com/sasikiranambati/github-profile-explorer/blob/main/src/App.jsx) (App router), [`server.js`](https://github.com/sasikiranambati/github-profile-explorer/blob/main/server.js) (Express API), [`src/pages/Favorites.jsx`](https://github.com/sasikiranambati/github-profile-explorer/blob/main/src/pages/Favorites.jsx) (Favorites page), [`src/pages/Profile.jsx`](https://github.com/sasikiranambati/github-profile-explorer/blob/main/src/pages/Profile.jsx) (Profile page)
