rajashekharexe/Chatwave ? reverse-engineered prompt

Build me a WhatsApp style chat app called ChatWave with real time messaging, group chats, typing indicators, online status, read receipts, and dark and light mode.

I want a clean, responsive experience that works well on both mobile and desktop. Users should be able to sign up and log in securely, then see their chats, send messages instantly, and know when someone is online or typing. Please make the UI feel modern and simple, with a smooth chat layout and a good looking sidebar for conversations.

Use React on the front end, Node on the back end, Socket.IO for live updates, SQLite for storing data, and JWT based authentication. If you need to check current docs or best practices while building it, go ahead and look them up. Make sure it runs locally with a simple dev setup and includes the basic pieces needed to deploy it later.
