+- On the browser side the `BrowserTracing` integration is enabled by default and adds automatic instrumentation for monitoring the performance of the application. The [Vue Router Integration](https://docs.sentry.io/platforms/javascript/guides/vue/configuration/integrations/vue-router/) is also automatically enabled. See all available [`BrowserTracing` options](https://docs.sentry.io/platforms/javascript/guides/vue/performance/instrumentation/automatic-instrumentation/).
 - On the browser side extra options for [Tracking Vue components](https://docs.sentry.io/platforms/javascript/guides/vue/features/component-tracking/) can be passed through the `vueOptions` object.
