## Overview

Discord Clone is a Vue/Express chat application backed by MySQL. Users register or log in, then browse public servers and channels or find and open one-to-one DMs; chat views load and poll messages and let users send, edit, and delete their own messages. Owners can create servers and manage their names and channels. Backend route details beyond the supplied excerpts are represented at the documented API entry point; unsampled route wiring is not expanded.

Main entry points: [`frontend/src/services/api.js`](https://github.com/travis-sova/discord-clone/blob/main/frontend/src/services/api.js) (API client), [`backend/index.js`](https://github.com/travis-sova/discord-clone/blob/main/backend/index.js) (Express API), [`frontend/src/views/main.vue`](https://github.com/travis-sova/discord-clone/blob/main/frontend/src/views/main.vue) (Chat navigation), [`frontend/src/main.js`](https://github.com/travis-sova/discord-clone/blob/main/frontend/src/main.js) (App routing)
