title: How to inject HTTP server in Nest 6?
body: <p>I'm correctly working on upgrading a project from Nest 6 and I can't figure out how to inject the currently used HTTP server instance into a class. </p>
  
  <p>Previously, I've been using the <code>HTTP_SERVER_REF</code> from <code>@nestjs/core</code> like this:</p>
  
  <pre><code>@Inject(HTTP_SERVER_REF) private readonly httpServer: HttpServer
  </code></pre>
  
  <p>This constant doesn't seem to exist anymore. I have a few monkey-patch solutions in mind that would give me access to the HTTP server but I'm wondering: Is there a new, proper way to inject the HTTP server? I'm using the default <code>@nestjs/platform-express</code> package by the way.</p>
