WebSocket Middleware Decorator

This file defines the Middleware class decorator for the @sodacore/core WebSocket (WS) module. It marks a class as WebSocket middleware, attaches the necessary metadata for discovery, and ensures the class is registered as providing WebSocket services. Middleware classes should implement the IMiddleware interface.

---

Features

• Middleware Registration: Adds metadata to register the class as middleware within the Sodacore WebSocket framework.
• Service Tagging: Tags the middleware as providing WebSocket services for internal discovery and execution.
• Autowiring Support: Sets the type metadata to enable automatic dependency injection and lifecycle management.

---

Usage

import Middleware from './decorators/middleware';

@Middleware()
export class MyWsMiddleware {
	async use(context, next) {
		// Middleware logic here
		await next();
	}
}

API

Middleware(): ClassDecorator

• Returns: A class decorator function that registers the class as WebSocket middleware.

---

How It Works

• Sets the type metadata to 'middleware' for autowiring.
• Adds 'ws' to the class's services metadata array for service discovery.
• The metadata set by this decorator is used by the framework to discover and execute middleware in the WebSocket request pipeline.

---

Notes

• Middleware classes should implement the IMiddleware interface to ensure compatibility.
• This decorator is intended for use with WebSocket middleware classes in the Sodacore framework.
