-The `BasePathProxyServer` is passed to the `CliDevMode` from core when the dev mode is trigged by the `--dev` flag.

-The basePathProxy also has another important job, ensuring that requests don't fail because the server is restarting and that the browser receives front-end assets containing all saved changes. We accomplish this by observing the ready state of the `Optimizer` and `DevServer` objects and pausing all requests through the proxy until both objects report that they aren't building/restarting based on recently saved changes.
