# Native crypto and a lighter bundle for the HLS.js and DASH.js Data SDK

> The FastPix Data SDK for HLS.js and DASH.js drops the external uuid dependency for native crypto APIs and points to an updated default metrics endpoint.

The FastPix Data SDK for HLS.js and DASH.js now uses native `crypto` APIs instead of the external `uuid` dependency, trimming bundle size, and points to an updated default metrics endpoint.

What's new:

* **Native crypto for IDs**: random number and UUID generation now use the built-in `crypto` APIs, removing the external `uuid` dependency and reducing bundle size.

* **Updated metrics endpoint**: the default metrics collection domain was updated for better endpoint reliability. Explicitly configured custom domains are still respected.

* **Local test pages**: added local test pages for HLS and DASH player integration.

* **Internal hygiene**: general code sanitization and hygiene improvements across the SDK internals for better reliability and long-term maintainability.
