Explainer https://github.com/WICG/compute-pressure/blob/main/README.md Specification https://www.w3.org/TR/compute-pressure Summary Provides a way for websites to react to changes in the CPU pressure of the target device, such that websites can trade off resources for an improved user experience. Blink component Blink>PerformanceAPIs>ComputePressure<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EPerformanceAPIs%3EComputePressure> Search tags compute pressure<https://chromestatus.com/features#tags:compute%20pressure> TAG review TAG review status Pending Risks Interoperability and Compatibility Gecko: No signal (https://github.com/mozilla/standards-positions/issues/521) WebKit: Negative (https://lists.webkit.org/pipermail/webkit-dev/2021-May/031845.html) This issue has been taken into account: https://github.com/WICG/compute-pressure/issues/24 Web developers: No signals Other signals: Security https://github.com/WICG/compute-pressure/issues/79 WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Goals for experimentation This API provides device-specific information and has been designed to provide useful and actionable metrics while preserving user privacy. We'd like to see if the information provided provides the user experience improvement sought after and if the shape matches developer expectations. We will measure API usage metrics and obtain developer feedback to validate our designs. We'll focus on feedback on UX changes on lower-powered devices specifically. Ongoing technical constraints Debuggability chrome-internals://compute-pressure Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? No Is this feature fully tested by web-platform-tests<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>? Yes DevTrial instructions https://github.com/WICG/compute-pressure/blob/main/HOWTO.md Flag name see https://github.com/WICG/compute-pressure/blob/main/HOWTO.md Requires code in //chrome?
