Chatroom Blueprint

The Chatroom Blueprint is a predesigned template that helps you quickly build a chatroom in ao. It is a great way to get started and can be customized to fit your needs.

Unpacking the Chatroom Blueprint

• Members: The Members array is used to store the users who have registered to the chatroom.
• Register Handler: The register handler allows processes to join the chatroom. When a process sends a message with the tag Action = "Register", the handler will add the process to the Members array and send a message back to the process confirming the registration.
• Broadcast Handler: The broadcast handler allows processes to send messages to all the members of the chatroom. When a process sends a message with the tag Action = "Broadcast", the handler will send the message to all the members of the chatroom.

How To Use:

1. Open your preferred text editor.
2. Open the Terminal.
3. Start your aos process.
4. Type in .load-blueprint chatroom

Verify the Blueprint is Loaded:

Type in Handlers.list to see the newly loaded handlers.
