# ModuleMetadata | Sentry for Effect

This integration only works inside a browser environment.

*Import name: `Sentry.moduleMetadataIntegration`*

Metadata can be injected by the Sentry bundler plugins using the `_experiments.moduleMetadata` config option. Once this integration is added, the metadata passed to the bundler plugin will be added to the stack frames of all events under the `module_metadata` property. This can be used to help tag or route events from different teams or sources.

**npm**

```javascript
import * as Sentry from "___SDK_PACKAGE___";

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  integrations: [Sentry.moduleMetadataIntegration()],
});
```

**Loader**

```html
<script>
  // Configure sentryOnLoad before adding the Loader Script
  window.sentryOnLoad = function () {
    Sentry.init({
      integrations: [Sentry.moduleMetadataIntegration()],
    });
  };
