sreeshanthh007/Chatly — reverse-engineered prompt

Build me a simple web app called Chatly. I want people to open the site, enter a name or sign in, see a clean chat screen, start a conversation, send messages, and see new messages appear without refreshing if that is practical.

Keep it easy to use, with a sidebar for chats, a main message area, timestamps, and a nice empty state when there are no conversations yet. Please include a small backend API and a frontend client, both in TypeScript, and make sure the app can be run locally with clear setup steps.

Add basic validation, loading states, friendly error messages, and a simple responsive design so it works on a phone and laptop. Don’t overcomplicate it. If you need current docs for the tools you choose, look them up online.
