Expose Decorator

This file defines the Expose method decorator for the @sodacore/core WebSocket (WS) module. It marks a controller method as callable via WebSocket commands, allowing the method to be invoked remotely using the namespace/methodName command format.

---

Features

• Method Exposure: Marks controller methods as exposed for WebSocket command invocation.
• Metadata Management: Stores metadata about exposed methods for later discovery and routing by the WebSocket framework.
• Command Routing: Enables remote clients to call specific controller methods using the namespace/methodName command format.

---

Usage

import Expose from './decorators/expose';

class ChatController {
	@Expose()
	async sendMessage(context, data) {
		// Handle sending a chat message
	}
}

API

Expose(): MethodDecorator

• Returns: A method decorator function that registers the method as exposed for WebSocket commands.

---

How It Works

• Retrieves the current list of exposed methods from the controller's metadata.
• Adds the decorated method's property key to the list.
• Updates the metadata so the WebSocket router can discover and invoke the method when the corresponding command is received.

---

Notes

• Only methods decorated with @Expose() can be called via WebSocket commands.
• The command format for invocation is namespace/methodName, where namespace is defined by the controller's @Controller decorator.
• This decorator is intended for use within WebSocket controller classes in the Sodacore framework.
