# Websocket to Container

Forwarding a Websocket request to a Container

WebSocket requests are automatically forwarded to a container using the default `fetch`method on the `Container` class:

**JavaScript**

```js
import { Container, getContainer } from "@cloudflare/containers";


export class MyContainer extends Container {
  defaultPort = 8080;
  sleepAfter = "2m";
}


export default {
  async fetch(request, env) {
    // gets default instance and forwards websocket from outside Worker
    return getContainer(env.MY_CONTAINER).fetch(request);
  },
};
```
