## Overview

Purbiya Foundation is a small web-based foundation administration site, served as static pages with an Express API. The principal supported workflow is an administrator logging in, then managing blog posts or events through browser forms and API requests, with records stored in MySQL and uploaded images saved under public/uploads. The tree also shows gallery, team, feedback, slider, and settings pages; their runtime wiring is not present in the sampled source, so they are represented without inferred API links.

Main entry points: [`server.js`](https://github.com/bhumikalohiya04-eng/purbiyafoundation_backend/blob/main/server.js) (Static site and API), [`db.js`](https://github.com/bhumikalohiya04-eng/purbiyafoundation_backend/blob/main/db.js) (Database connection), [`public/index.html`](https://github.com/bhumikalohiya04-eng/purbiyafoundation_backend/blob/main/public/index.html) (Login page), [`public/js/login.js`](https://github.com/bhumikalohiya04-eng/purbiyafoundation_backend/blob/main/public/js/login.js) (Login client)
