PWA Kit and Managed Runtime

**PWA Kit**

**Optimize Site Performance with \_\_server\_timing**

This feature is generally available from PWA Kit version 3.7. With the \_\_server\_timing query parameter you can monitor the performance of your PWA Kit site to support your optimization efforts. The parameter provides access to the Server-Timing HTTP header and logs, that offer metrics about parts of the server-side rendering process such as route matching, component loading, and fetch strategies. Performance metrics logs are also available in Log Center. See [\_\_server\_timing](https://developer.salesforce.com/docs/commerce/pwa-kit-managed-runtime/guide/debugging.html#__server_timing).

**Update SLAS Calls to Prevent Unauthorized Access Across Sites**

Retail React App version 4.0 consumes the new versions of [Commerce SDK React](https://salesforcecommercecloud.github.io/pwa-kit/) and [Commerce SDK Isomorphic](https://github.com/SalesforceCommerceCloud/commerce-sdk-isomorphic). These SDKs now satisfy Shopper Login and API Access (SLAS) guidance to pass channel\_id as an argument when retrieving guest access tokens. See [Guest Tokens](https://developer.salesforce.com/docs/commerce/commerce-api/guide/slas.html#guest-tokens).

**Store Locator Support**

Store locator is generally available with Retail React App version 4.0 or later and Commerce SDK React version 2.0.1 or later. With our store locator, your shoppers can find nearby storefront locations based on their ZIP code, city, and more. Easily extend your store information in Business Manager to customize the displayed location metadata on your site. See [Boost In-Store Sales with Store Locator](https://developer.salesforce.com/docs/commerce/pwa-kit-managed-runtime/guide/store-locator.html).

**Increase Revenue with Product Bundles**

Product bundles are generally available with Retail React App version 4.0 or later and Commerce SDK React version 2.0.1 or later. Use product bundles to group multiple related products into one orderable product for shopper convenience and personalization. Shoppers can update bundle variants and quantities directly in their cart. For example, an online sports apparel store can offer a "Runner's Bundle" so shoppers can select shoe size, apparel size, and fitness tracker model directly in their cart. Product bundles can help you to reduce cart abandonment and improve inventory management. See [Product Bundles](https://help.salesforce.com/s/articleView?id=sales.cpq_bundle_products.htm&type=5&language=en_US).

**Managed Runtime**

**Origin Lockdown with Embedded CDN (eCDN)**

Restrict access to a Managed Runtime environment to traffic coming from eCDN. Set a shared access control header across eCDN and environment to ensure that shoppers, bots, and crawlers don’t access your environment directly.

See the updated [Launch Your Storefront Guide](https://developer.salesforce.com/docs/commerce/pwa-kit-managed-runtime/guide/launching-your-storefront.html) and the new [`upsertOriginHeaderModification`](https://developer.salesforce.com/docs/commerce/commerce-api/references/cdn-api-process-apis?meta=upsertOriginHeaderModification) API for details on how to configure Managed Runtime and eCDN to lock down your environment.

**Debug Faster in Log Center**

Quickly find logs generated by your PWA Kit site by searching on namespaces added as prefixes to logs in Log Center. The namespace pinpoints the specific part of your codebase where an error occurred, helping you to focus your troubleshooting efforts. See [Debug Using Log Center](https://developer.salesforce.com/docs/commerce/pwa-kit-managed-runtime/guide/debugging.html#debug-using-log-center).
