+By default, the dev-server will reload/refresh the page when file changes are detected. [`devServer.hot`](#devserverhot) option must be disabled or [`devServer.watchContentBase`](#devserverwatchcontentbase) option must be enabled in order for `liveReload` to take effect. Disable `devServer.liveReload` by setting it to `false`:
