[email protected] Explainer No information provided Specification https://github.com/whatwg/cookiestore/pull/292 Summary Allows callers to specify a `maxAge` when setting a cookie with the Cookie Store API. Cookie expiry time is already configurable using the `expires` attribute, but `maxAge` provides a more idiomatic option and aligns the Cookie Store API with the options provided by `document.cookie` and the `Set-Cookie` HTTP Header. Blink component Blink>Storage>CookiesAPI <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EStorage%3ECookiesAPI%22> Web Feature ID cookie-store <https://webstatus.dev/features/cookie-store> Motivation Currently, developers can use the `expires` attribute when setting a cookie with the Cookie Store API to set an absolute timestamp for expiry. This can be unintuitive and is impacted by client-side clock skew. RFC6265bis <https://datatracker.ietf.org/doc/draft-ietf-httpbis-rfc6265bis/> and the document.cookie API provide a `Max-Age` attribute, which allows for relative cookie lifetimes and ergonomic deletion. We should provide a `maxAge` option in the Cookie Store API to support relative expiry and align with these APIs. Initial public proposal https://github.com/whatwg/cookiestore/issues/57 TAG review Not requested, this is a relatively small feature that has no impact on behavior or new information exposed through the API. TAG review status Not applicable Risks Interoperability and Compatibility Additive feature with no impact to existing cookies/behavior. Does not expose additional information or functionality-- setting a cookie's absolute expiry with the `expires` value is already supported in the API. Gecko: Positive (https://github.com/mozilla/standards-positions/issues/1334 ) WebKit: No Signal (https://github.com/WebKit/standards-positions/issues/597) We are actively developing this feature in collaboration with WebKit https://github.com/whatwg/cookiestore/pull/292#pullrequestreview-3538599229 Web developers: Positive (https://github.com/whatwg/cookiestore/issues/57) Could be easier for developers to work with now-relative values, aligns the Cookie Store API with the features provided by document.cookie and RFC6265bis Other signals: 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? No Debuggability Cookies (and their properties such as expiry time) are debuggable through the Application > Cookies tab on DevTools Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?

False Tracking bug https://issues.chromium.org/430926231 Estimated milestones Shipping on desktop 145 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
