Introducing view-transitions-mock, a non-visual polyfill for same-document view transitions. @bramus built a spec-compliant JavaScript implementation of the View Transition API that works across all browsers. It handles document.startViewTransition(), the ViewTransition class with its promises, and view transition types. Animations are skipped in unsupported browsers, but DOM updates work as expected. #viewtransition #polyfill
Представляем view-transitions-mock — невизуальный полифил для view transition в рамках документа. Брамус Ван Дамм создал JavaScript-реализацию View Transition API совместимую со спецификацией, которая работает во всех браузерах без кучи условий в коде. Она обрабатывает document.startViewTransition(), класс ViewTransition с промисами и типы View Transition. Обновления DOM идентичны нативным, но анимации пропускаются в старых браузерах. #viewtransition #polyfill
