In the 8.0 release, we described TTI's waning role, and today we have the followup. Time to Interactive (TTI) no longer contributes to the performance score and is not displayed in the report. However, it is still accessible in the Lighthouse result JSON.
Lighthouse now includes type declarations! Our example TypeScript recipe demonstrates how to achieve proper type safety with Lighthouse.
Third-party Entity classification
Since Lighthouse 5.3, the community-driven third-party-web dataset has been used to summarize how every third-party found on a page contributes to the total JavaScript blocking time, via the third-party-summary audit. With Lighthouse 10.0, we are adding a new property to the JSON result (entities) to make further use of this dataset. Every origin encountered on a page is now classified as first-party or third-party within entities. In 10.0, this classification is used to power the existing third-party filter checkbox.
In a future version of Lighthouse, this will be used to group the table items of every audit based on the entity it originated from, and aggregate the impact of items from that specific entity.
🆕 New Audits
Back/forward cache
The Back/forward cache (bfcache for short) is a browser optimization that serves pages from fully serialized snapshots when navigating back or forwards in session history. There are over 100 different reasons why a page may not be eligible for this optimization, so to assist developers Lighthouse now attempts to trigger a bfcache response and will list anything that prevented the browser from using the bfcache. #14465
