This integration only works in the Node.js and Bun runtimes. Requires SDK version `8.33.0` or higher.

*Import name: `Sentry.lruMemoizerIntegration`*

This integration is enabled by default when performance monitoring is enabled. If you'd like to modify your default integrations, read [this](https://docs.sentry.io/platforms/javascript/guides/sveltekit/configuration/integrations.md#modifying-default-integrations).
