#polyfill — Public Fediverse posts

In defense of polyfills. @leaverou pushes back on the claim that polyfills harm the web platform. She argues the need for fallbacks persists regardless, and banning polyfills just scatters worse ad-hoc code everywhere. Standardized APIs decouple code from the spec, so libraries swap freely. The real problem is a slow standards process that waits for implementer interest before demonstrated need. #polyfill #tools

В защиту полифилов. Лия Веру спорит с мнением, что полифилы вредят веб-платформе. Она объясняет, что потребность в фолбеках никуда не денется, а запрет лишь плодит худший разрозненный код по всему проекту. Стандартные API отделяют код от спецификации, поэтому библиотеки легко заменяются. Настоящая проблема — медленный процесс стандартизации, который ждёт интереса браузеров вместо того, чтобы реагировать на явную потребность разработчиков. #polyfill #tools

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

Y'all remember #PolyfillIO?

I realize the lesson there is; don't depend on code from domains you don't control, and in an ideal world that's what you should do

But is there still a need there? Are there #webPlatform features you'd like to use but you don't want to introduce a build process just to bundle the #polyfill from #NPM?

Or is there no point in #polyfills since #browsers don't share caches between origins these days so there's no precaching benefit anymore?
