title: NestJS UDP Server without HTTP
body: <p>Is there any way to use nestjs as standalone udp server? I created custom udp server adapter as explained in documents but when i try to star application i gives me this error.</p>
  
  <p><em>No driver (HTTP) has been selected. In order to take advantage of the default driver, please, ensure to install the "@nestjs/platform-express" package ($ npm install @nestjs/platform-express).</em></p>
  
  <pre><code>async function bootstrap() {
  
    const app = await NestFactory.create(AppModule);
  
    app.useWebSocketAdapter(new UdpAdapter(app));
  }
  </code></pre>
