# FetchStreamPerformance | Sentry for SolidStart

This integration only works inside a browser environment. Requires JavaScript SDK version 11 or later.

*Import name: `Sentry.fetchStreamPerformanceIntegration`*

The FetchStreamPerformance integration measures how long streamed fetch responses take to finish. It captures spans from when response headers arrive until the body finishes, up to 90 seconds.

Use it with [BrowserTracing](https://docs.sentry.io/platforms/javascript/guides/solidstart/configuration/integrations/browsertracing.md) or your framework's routing integration.

```javascript
Sentry.init({
  integrations: [
    Sentry.browserTracingIntegration(),
    Sentry.fetchStreamPerformanceIntegration(),
  ],
});
```

Responses are tracked when they have no `content-length` header and their `content-type` starts with one of these values:

* `text/event-stream`
* `application/x-ndjson`
* `application/stream+json`

This integration has no configuration options.
