A simple chat application built with SpacetimeDB.

QuickStart Chat is a basic chat application that demonstrates the core functionality of SpacetimeDB. It allows users to:

• Connect to a chat room
• Set their username
• Send messages to the chat room
• See who is online

The application uses SpacetimeDB's real-time database capabilities to synchronize data across all connected clients.

1. Clone the repository:

   git clone https://github.com/yourusername/quickstart-chat.git
   cd quickstart-chat

2. Publish the module to SpacetimeDB:

   cd server
   spacetime publish

spacetime client connect quickstart-chat

spacetime call quickstart-chat set_name "YourUsername"

spacetime call quickstart-chat send_message "Hello, World!"

spacetime logs quickstart-chat

spacetime sql quickstart-chat "SELECT * FROM message"
